What lubricant to use for a screwdriver gearbox

What and how to properly lubricate a drill?

What is the best way to lubricate an old Soviet-made drill?
the main thing is that before lubricating all parts of the gearbox, you need to remove the old grease and wash all the parts (except for the bearings). Well, then you can lubricate, as other opponents have already said, with lithol or graphite lubricant. it more or less reduces the wear and tear of all parts. and at a price it is more affordable for most. And it is imperative to coat the part of the drill or drill that is inserted into the cartridge or barrel. This prevents the base of the cartridge or the striker from breaking in the perforated drill.

For Soviet equipment, no better lubricant than Litol-24 has been invented; it must be put into the gearbox and lubricate the guides and gears in Soviet, and not only Soviet, equipment.

Naturally, before lubrication, you need to thoroughly clean and wipe all parts dry (no need to wash with solvent, diesel fuel, or gasoline!) , just clean and wipe dry.

Place and apply fresh Litol-24 and assemble - that’s all!

Litol-24 lubricant will withstand high speeds and increased temperatures and increased loads and friction, it is put into the gearbox in quite a large volume, as the experts say - the excess will come out!, so its work is designed for a long time, and replacement is actually only during repairs.

In Soviet times, both people and technology were not spoiled by delicacies - they grabbed what they gave.

So you can treat your veteran drill with what remains from Soviet times - even simple grease.

Among modern lubricants for gear mechanisms, you can use CV joint grease (motorists know what it is), lithol. Bosch lubricants have proven themselves well in gear drives.

If you're lucky and come across this

When servicing the drill, do not miss this moment: remove, as thoroughly as possible, all the old lubricant, because there will probably be metal particles from the gears and other dirt that have penetrated inside the tool.

There are a lot of types of drills, both by purpose (impact, hammerless, drill-mixers, etc.) and by type of power, these include manual, electric and pneumatic.

Drills also differ in power and in the number of revolutions it can produce.

Manufacturers are different, many manufacturers produce their own lubricants and recommend using only them.

In any case, in order to lubricate the drill (its gearbox), you need to get to it (the gearbox).

There are also a lot of options here, perhaps your drill needs to be “split” into two parts (I’m talking about the body, unscrew the screws that secure the body).

It is not necessary to disassemble it into its components.

They removed the old lubricant (although this is not always done), thoroughly cleaned it of the old lubricant (a rag is convenient), put in a new one, in general, that’s all, there are no difficulties here.

Albina always lubricated his “ancient” Soviet drill with Litol-24, there was no thought of switching to something more “advanced”, the lubricant was completely satisfactory.

Rotary hammers require careful care during use. For their long-term operation, different types of lubricants are used. The compositions can be mineral, semi-synthetic, and also synthetic. Mineral ones are made from petroleum products, so they quickly lose their operational features and have to be replaced quite often.

It is very important to choose a composition that will be suitable for the selected type of hammer drill.

The best lubricant for rotary hammer drills

Having considered the purpose and requirements for lubricants for a hammer drill, let's figure out which lubricant for a hammer drill is better in terms of characteristics and reviews. To do this, we have compiled a rating of popular examples that have already been tested by time and operation in domestic and construction conditions.

Makita 196804-7

Lubricant from a Japanese brand, designed only for application to the shank and inside the chuck. Available in a white and red tube with the brand logo and index. The container holds 95 g, which lasts from a month to a year, depending on the frequency of use of the hammer drill. The soft walls of the tube make it easier to squeeze out the composition and apply it to the equipment.

Pros of Makita 196804-7

Does not delaminate even during long-term storage.
When heated, it does not turn into wax.
Produced directly in Japan.
Convenient packaging for squeezing.
The tube easily fits into a suitcase for transportation.
There is a loop for hanging in the garage or other work area.

Cons of Makita 196804-7

The cost is relatively high.
The white bottle gets dirty quickly.
The packaging does not indicate the composition - it is difficult to find a similar one, but cheaper.

Conclusion. This is one of the highest quality lubricants for hammer drills used in intensive mode. Reviews from craftsmen show that with it the equipment does not jam even when chiseling walls for 6 hours every day. In this case, only one chisel is used at all times. If you want to protect the cartridge and equipment as much as possible, then purchase products for drills from Makita.

Arsenal AR-401 (100 g) PATRIOT

In second place in the ranking is a product from the American brand “Patriot”. The product stands out at an attractive price. Suitable for lubrication of all drills with rotation speeds of 1000-4000 rpm. The tube capacity is 100 g.

Pros of Arsenal AR-401 (100 g) PATRIOT

The tube cap has no relief and is difficult to unscrew while wearing work gloves.

Conclusion. This product is notable for its economical consumption. Users in reviews share that it is enough to squeeze 0.5 g onto the drill shank, so that this is enough to lubricate the equipment during intensive use. True, such accelerated distribution over the surface is due to increased fluidity, so it needs to be added less, but more often.

Bison ZSB-125

Third place in the ranking goes to the domestic lubricant from Zubr. Its composition has a semi-synthetic base. The manufacturer added special additives to increase the positive properties of the substance under extreme loads. The product is suitable for drills, chisels, and crowns. It can be chambered in “light” SDS+ cartridges and “heavier” SDS-Max cartridges. The lubricant is resistant to water and does not form an emulsion. The product reliably protects the metal components of the hammer drill from abrasion and corrosion.

Pros of Zubr ZSB-125

Relatively low cost.
Tube capacity - 125 g.
Large inscription “For drills”, so as not to be confused when servicing the gearbox.
Loop for hanging grease on a hook in the garage.
For SDS+ drills, a thin layer is sufficient.
Nano-technologies were involved in the development of the composition.

Cons Zubr ZSB-125

It is difficult to unscrew the cap with sweaty hands.
It quickly becomes liquid.
It flies out of the cartridge onto the wall.
Difficult to wipe off wallpaper.

Conclusion. This lubricant has a wide temperature range. It does not thicken much at negative temperatures down to -50 degrees, and remains moderately fluid when it reaches +130 degrees. If you work as a hammer drill in the cold or in an open space in the summer, then this product will be the best.

Elitech 2006.000100

This category is completed by another domestic lubricant on a semi-synthetic basis. It is available in a soft tube with a capacity of 60 g. The substance is designed to reduce tool friction and protect against corrosion. The temperature range allows the product to be used from -55 to +140 degrees.

Pros of Elitech 2006.000100

There is no strong splashing when overheating.
Affordable price.
Doesn't turn into oil.

Cons of Elitech 2006.000100

It gets very dark when drilling for a long time.
If stored in a warehouse or garage for a long time, it may dry out or delaminate.
The tube capacity is smaller than other brands.

Conclusion. This lubricant best prevents metal corrosion. With it, your drills and chuck elements will remain intact and without traces of rust. If you prefer to use expensive drills and bits from domestic manufacturers, then this lubricant is perfect.

What it is?

Lubricant is a viscous substance that reduces the coefficient of friction between tool parts. The operation of a rotary hammer is associated with a huge number of different rotational movements, which increases the degree of wear of structural elements.

When drilling, quite a lot of dust is released, which significantly impairs the operation of the device, which is why it requires periodic lubrication.

Which parts need lubrication?

In terms of its physical and technical parameters, lubricant for drills, piston, drills, as well as gearboxes and other elements is almost no different from lubricants of all other types. This is a rather viscous substance with an oily structure; it is used to reduce the friction force of rotating parts, thereby reducing wear on operating mechanisms.

Lubrication only reduces the wear of mechanisms, but does not eliminate it. But it is quite possible to significantly extend the period of their operation.

Over time, the lubricant becomes saturated with dust, which is formed during drilling, grinding and crushing - this leads to a change in the degree of its viscosity. In this situation, friction, on the contrary, increases and the wear rate increases, so the lubricant should be updated from time to time. In order for the hammer drill to last longer, you should clearly understand which parts can be lubricated and how often this should be done.

Features of oil selection

One of the main parameters that is taken into account when purchasing a lubricant is the viscosity of the oil. High quality products are usually expensive, but in this case there is no need to save. A hammer drill is an expensive tool, so you should constantly take care of its performance. Typically, the types of lubricants are listed in the instructions, but if the information is missing, you can always seek advice from the manager of the service center or retail outlet where the device was purchased. Specialists will select the optimal composition for the hammer drill.

There are also universal compounds that can be used to lubricate different types of drills. In recent years , graphite lubricants have become very popular because they have good viscosity and a high level of quality.

Experienced specialists confirm that many branded mixtures are of much lower quality than mixtures made on the basis of graphite . In addition, they have a fairly affordable price, so many people confidently choose them.

For hammer drills, you should take substances such as grease and lithol . Litol - 25 is a high-quality, long-lasting material that has a low cost. Therefore, it is very popular among power tool owners.

Do not forget that such mixtures can cause slight braking of rotating structures, and can also significantly increase the heating of the tool during operation.

If we talk about specialized lubricants, it should be noted that to lubricate various parts you need to use oils that are suitable specifically for them. For example, oils that are used to process the gearbox are not suitable for lubricating drills.

And to lubricate the gearbox, a more liquid composition is required , which must completely cover the contacting parts, filling the free cavities. But if the gearbox has plastic parts, then the lubricant can only be silicone.

The transmission mechanism can also be lubricated with plastic compounds, but not all equipment can function without interruption when using products with a similar consistency.

Thicker mixtures are suitable to reduce tail tip wear. Usually the packaging indicates that they are intended for processing drills.

If you don’t have the necessary product at hand, you can opt for its graphite analogue, although it removes heat much worse than specialized oil.

For cartridges, you can use silicone lubricants . Lubricants are branded, produced by manufacturers of electrical tools, for example, Hitachi or Metabo, as well as AEG, Bosch or Interskol. They can also be produced by enterprises specializing in the production of lubricant mixtures.

The most popular brands are:

Bosch - produces oils for lubricating gearboxes and tail attachments;
Makita – purchased for drills;
Lubcon Thermoplex – produces products for gearboxes;
Turmogrease - universal lubricants;

Nanotek – used for shanks;
Interskol – optimal for processing drills;
PRORAB - is a composition used for processing the seats of tail parts;
Kress – used for lubrication and greasing of drills.

Bosch and Makita are in greatest demand among users.

How to properly lubricate parts?

When it comes to lubricating a hammer drill at home, as a rule, we mean replacing the lubricant on its individual parts yourself. First of all, you should lubricate the gearbox - this mechanism is quite easy to disassemble, but has a complex structure, so all actions must be carried out in a strictly defined order.

First you need to prepare the necessary materials:

dry clean cloth - rags;
plumbing tools that are necessary for assembling the gearbox;
the lubricant itself.

In most cases, world-famous manufacturers such as Bosch and Makita indicate in the instruction manual the entire procedure for disassembling and assembling devices and provide important recommendations. Owners of rotary hammers who are faced with such work for the first time, following these tips, can master all the manipulations quite quickly, spending a minimum of effort.

But if such a guide is not at hand, then you should work according to a certain algorithm.

The tool must be kept free of dust and dirt.
When disassembling and subsequently reassembling a drill and hammer drill, you need to remember as accurately as possible the order of arrangement of all functional parts, so as not to confuse them during disassembly. It is better to use video recording.
All work related to lubrication of parts is carried out only after a certain time after stopping the drill. It must cool down, otherwise the cooled lubricant can cause interruptions in the operation of the power tool if it comes into contact with hot areas.
After all the basic parts are removed, including the gearbox, they are washed with spindle oil or gasoline, and then thoroughly dried from excess moisture. Particular attention should be paid to the gearbox.
Each part of the device should be inspected as carefully as possible. In some areas there is no lubricant, which means that there is no need to apply a new compound to this place.
After applying the composition, the gearbox is carefully reassembled in the reverse order. If this is done correctly, the hammer drill can be used immediately.

Home workshop: how to repair a screwdriver gearbox?

Any tool, regardless of model and brand, will sooner or later break down. A screwdriver is no exception: individual parts and assemblies wear out over time, and without proper care or under force majeure circumstances they may fail.

The main functional load when operating the tool is distributed through the gearbox between the engine and the chuck, so if something happens to the gearbox, the work will stop. In order not to spend money on repair services, it is enough to use the advice of specialists to restore the operation of the unit yourself.

Useful tips

Owners of drills and hammer drills often wonder about the frequency of lubrication. Determining the time frame is problematic, but on average, the optimal period for changing the oil is considered to be a period of 12 months if the tool is operated at medium intensity.

Lubrication of many modern devices has been greatly simplified thanks to the introduction of a number of useful improvements. For example, popular brands often make special holes in the equipment into which a lubricant is simply poured , and there is no need for its disassembly and subsequent reassembly.

Typically, such systems are designed very competently - in addition to holes for filling oil, there are also outlets through which spoiled lubricant is drained.

There are special marks on the surface of the device that directly indicate how much lubricant is needed to maintain the functional operation of the power tool.

The only thing that is required in this case is to blow out the hole as intensively as possible before use. To do this, you can use a compressor and then flush the hole with gasoline.

Lack of lubricant often becomes the main cause of serious malfunctions of the hammer drill. In crushing mode, the lubricant is wasted in a significant amount, and if there is too little lubricant on the gearbox or drill, this often causes overheating of the entire device.

At the same time, there is no need to be zealous - if too much oily composition is applied, the rotation speed of the drill will be reduced, and this will also worsen the performance of the tool as a whole. In addition, excess lubricant will end up on working surfaces that are difficult to clean.

Lubricant for a rotary hammer allows you to extend its service life and make its use more efficient. In order for the effect of a lubricant to bring the expected results, when choosing it, you should take into account not only the characteristics of the lubricant, but also the technical parameters of the device for which it is planned to be used. When choosing how to lubricate a hammer drill, you must also keep in mind the fact that different parts of such equipment require different types of lubricant.

Proper lubrication of the hammer drill gearbox

There is an opinion that the presence of lubricant on the moving elements of the hammer allows you to postpone its replacement for a long time. Meanwhile, this opinion is fundamentally wrong, and in order to change it, it is enough to get acquainted with the principle by which lubricants work.

In modern construction it is very difficult to do without reliable and high-quality tools. One of the necessary electrical appliances is a hammer drill. It is with its help that you can drill holes in almost any surface or make a channel for wires; this tool also replaces a drill and jackhammer with almost no problems. Such a replacement is possible due to the fact that this equipment produces both rotational and longitudinal-axial movements. The article will discuss which lubricant to lubricate a hammer drill in order to maximize its service life.

Content:

The very first hammer drill appeared in 1851; it was then used in the mining industry, was manual and did not have such rich functionality. But after just over 150 years, it has become one of the necessary tools for the home craftsman and professional builder. The design of the hammer drill is quite complex and in order to preserve it for a long time and not subject to premature repair, it is recommended to carefully monitor its condition. First of all, it is necessary to lubricate certain parts. This process will help to significantly extend the life of the electric assistant.

To understand why a hammer drill requires lubrication, you should get to know its structure and operating principle in more detail.

Main structural elements of a rotary hammer

In order for the hammer drill to perform its direct functions, it is necessary to apply a certain force towards the surface being processed. It is possible to obtain such an impulse thanks to a pneumatic or electromagnetic mechanism. The power of the tool depends on the impact energy and the power of the electric motor. That is, the higher the values in joules and watts, the more powerful the tool.

The main elements of a rotary hammer with an electromagnetic type of impact include:

electromagnetic coil (usually 2 pieces);
core;
Boer.

And the elements of a tool with a pneumatic type of action include:

piston and cylinder;
striker;
drill (or other attachment).

Rotary hammers with pneumatic impact are more common today than those with electromagnetic impact. There are several options for their execution, the main two, which differ from each other in that the first uses a swinging bearing (the so-called “drunk”), and the second uses a crank mechanism. Tools with the first option are lightweight and compact, while with the second option, as a rule, they are medium or heavy in weight.

Also, the tools are usually equipped with:

chuck - necessary for securing the nozzle, there are several types: SDS Plus (installed in light tools) and SDS max (for medium and heavy tools), the first type has the ability to install a drill with shanks with a diameter of 1 cm, with the second type the shank diameter is 1 .8 cm, also SDS Plus has three operating modes (drilling, drilling, impact), and SDS max only two (drilling and impact). It is also possible to install a traditional jaw-type chuck (a hollow cylinder with an adjusting ring and metal cams that hold the nozzle);

chuck replacement system - quick change from one type of chuck (SDS) to another (cam);
reverse – changes the rotation of the drill; it can be of brush or electronic type;
gearbox - is a single housing (crankcase) in which various gears (bevel, cylindrical, worm) are located, this arrangement of parts allows you to protect the main mechanism from damage and dirt and dust, the main function of the element is to change the speed of rotation of the shafts;
vibration protection - there are passive or active (labeled AVS, most heavy hammer drills are equipped with) type, they dampen vibration from impacts, that is, they reduce it, but this effect cannot be completely removed, the active anti-vibration system has a shock-absorbing device - a counterweight with a spring, and the passive system consists of rubber pads and a rubberized handle, that is, it protects a little worse and is installed only on light household tools;
various indicators;
speed controller;
safety clutch - necessary to stop the rotation of the cartridge in cases where the nozzle jams during operation, there are two types: spring-cam (consists of coupling halves with teeth and a spring) and friction (consists of disks);
electronic immobilizer - to stop the hammer drill in emergency situations, for example, in cases of power surge, to avoid problems with the tool and maintain its performance;
motor - there are two types: transverse (vertical arrangement, has a larger area for cooling and is considered more protected from dust generated during operation, as a rule, used in cases where long-term drilling is necessary without interruptions) and longitudinal (horizontal arrangement helps to make the tool more balanced, that is, increases its ergonomics, and also more compact).

Having understood the structure of the hammer drill, you should know what kind of care the tool needs.

How to lubricate a hammer drill

The main purpose of a hammer drill is to drill, chisel and drill various surfaces. As a rule, most materials that this tool works with have a tendency to become dusty. Small particles falling on internal parts clog the device. It should be taken into account that the elements are in motion, during which they come into contact with each other, and, therefore, their abrasion may begin. To maintain the functionality of the tool, it is necessary to regularly clean and lubricate it. Only with such care is it possible to maximize the service life, avoid early breakdowns and expensive repairs.

Important: lubricant has several main types. One type is used for the gearbox and a completely different type is needed for drills or drill bits. Each device has detailed operating instructions, which specify clear lubrication intervals. These are the recommendations that should be followed.

There are general rules for all types of hammer drills.

How to lubricate a hammer drill gearbox

Thus, to lubricate the gearbox, it is most often recommended to use compounds in the form of liquid oil, which is poured in a certain dose into the tool body (into holes specially designed for this purpose). This oil fills the gear housing and is reliably isolated inside using caps installed on the holes or bolts. During operation, the parts are evenly coated with this product. Makita is considered the most popular manufacturer of oil for lubricating gearboxes.

As an example, we can name two popular types of products from these manufacturers, which are used during initial assembly or during tool repair:

lubricant “Makita P-08361” 30 ml, approximate cost 100 rubles;
oil “Bosch 1615430005” 45 ml, price about 300 rubles.

Advice: there are also plastic compositions for gearboxes (in the form of a cream), but it is worth considering that not all models of tools can work stably with products of this consistency. Every owner of a rotary hammer should have a gear lubricant. But if the hammer drill is under warranty, then it is best to carry out such an operation using the services of service centers, especially if there are no special holes (that is, if it is necessary to disassemble the tool).

How to lubricate a hammer drill

Lubricant for rotary hammer drills is used to reduce wear on the bits, and also extends the service life of the rotary hammer (including by reducing the amount of dust penetrating inside). Lubricant is applied before each insertion of the drill into the chuck; for this purpose, the grooves of the nozzle are lubricated with a small amount of the product. Before performing this operation for the first time, you need to carefully read the instructions for the instrument. This is necessary in order to understand how to properly disassemble/assemble a hammer drill without damaging its elements and achieve proper operation.
The amount of lubricant and its quality determine how the power tool will function. If the ratio is selected incorrectly, the device may overheat and even fail. Therefore, before using this or that lubricant, it is worth checking whether this manufacturer and type of product are included in the recommendations in the operating instructions for the hammer drill. The most common compositions for lubricating drills are also produced by the Bosch and Makita brands, only the products have a thicker consistency.
When starting to lubricate, you need to rinse and blow out the tool, wipe it dry and only then apply a new layer of protective agent. Those parts that do not need to slide should not be lubricated, as this can only damage the hammer drill. Such elements include, for example, a transmission coupling.

How to lubricate a hammer drill chuck

The composition should also be applied to replaceable drill bits in the form of a cartridge. The amount of the substance must be as indicated in the instructions. Too much or too little of it can cause the instrument to fail.

It is recommended to lubricate the shanks before each installation; after removing the nozzle, it must be wiped from dust and waste oil.

Choosing the type of lubricant is not a problem; the instructions have clear recommendations; if they are not available, then you can choose almost any product from trusted manufacturers.

The German company, which produces various pneumatic and electric tools, was founded in 1928 and has established itself as a reliable manufacturer. All tools have a company warranty of up to two years, and in some cases up to 10 years (subject to service in specialized service centers).

Product range

“Kress 98035301” – lubricant for drills (pack of 50 ml).

Litol

Sometimes a lubricant such as “Litol-24” is used in household use. This is petroleum oil that is thickened with a special composition. The product is characterized by chemical and mechanical stability, heat resistance and frost resistance (does not lose its properties at temperatures from +120 to -40 degrees), and also has water-repellent qualities. Such products are manufactured in accordance with GOST and have several modifications.
A modern type of product is a product called “Litol-24 LUX” - it is distinguished by a light yellow color and excellent water resistance, it comes in various packaging packages of 25, 10, 2, 0.8 kg, the approximate cost for 1 kg is about 100 rubles. (the larger the package, the lower the price per kilogram).

This product is used for gear and articulated gears and for all types of bearings, as well as for lubricating equipment in power tools. Experts recommend treating such a composition with caution, since the lubricant can cause additional heating of the hammer drill. In addition, it is not characterized by long and stable operation; it is also better to refrain from using it in battery units.

Branded lubricants, which are indicated in the instructions for the tool, will be more useful than using Litol, since they are characterized by better water resistance, and therefore more reliably protect the product from corrosion.

Proper lubrication of the hammer drill gearbox

Why do hammer drill elements need lubrication?

Lubricant, including that used for a hammer drill, is a viscous substance, the use of which is necessary to reduce the coefficient of friction between structural elements of a mechanical device moving relative to each other. Thus, lubricant only reduces friction, but does not eliminate it completely, so the lubricating composition is gradually saturated with wear products of rubbing parts - metal dust. As a result, not only does the viscosity of the lubricant change, but it itself becomes the cause of more intensive wear of the equipment.

It should be immediately noted that viscosity is the most important parameter that one must focus on when choosing a lubricant composition of a certain type.

Over time, the lubricant becomes dirty and loses its properties.

How to choose the right lubricant for a specific hammer drill model? First of all, you need to take into account the recommendations of the equipment manufacturer, who must indicate both the required type of lubricant and the frequency of its replacement. It is especially important to focus on such recommendations while the warranty period for the hammer drill has not yet expired. Otherwise, if the device breaks down, you will not be able to take advantage of the manufacturer’s warranty.

Many owners of rotary hammers, after the warranty period has expired, begin to use not branded compounds for lubrication, but their cheaper analogues - litol or grease. Of course, such lubricants are not capable of harming the structural elements of the hammer drill, but when using them, you should keep in mind that they should be replaced much more often.

Causes of failure

Like any mechanical unit, when the gearbox operates, the parts are affected by frictional forces, causing them to gradually wear out or wear out and lose their “adhesion.” In order to avoid this, all parts of the assembly must be properly lubricated.

Therefore, the first reason for gear unit failure is a lack of lubrication (but there may also be an excess of it).

Also, the gearbox is affected by such a “scourge” of mechanics as dust. It settles on the parts and during operation heats up along with them. This is especially dangerous for plastic gears, since under the influence of heat from dust they are subject to deformation - which leads to failure.

Finally, another nuisance for the gearbox is the ingress of foreign particles into it. Clogging between the teeth, they jam them. Because of this, when the motor shaft rotates, an excessive load is created on other structural elements, which leads to their destruction.

Reference. If one of the reasons or force majeure has led to damage to an element of the gear unit (gears, bearings or shafts), it is often necessary to install a new gearbox as a whole, since not all manufacturers have on sale individual gearbox parts to make a replacement.

Gearbox lubrication

The hammer drill gearbox is the most complex component of the device in terms of design, so it requires special attention. Lubricating the rotary hammer gearbox is not so difficult, but self-assembly of a previously disassembled unit can cause serious difficulties. If the hammer drill is still under warranty, then with questions about lubrication of its gearbox, it is best to contact a specialized workshop that provides warranty service for such equipment.

A detailed diagram of your hammer drill will help you understand the mechanism and correctly assemble the tool

If the hammer drill you own is not covered by any warranty or the warranty period for your equipment has already expired, and the authorized service center is located far enough away, you can lubricate the gearbox yourself, observing maximum care and attention. For this you will need:

a set of plumbing tools with which you will assemble and disassemble the hammer drill gearbox;
clean rags;
the composition itself for lubrication.

“Native” lubricant for the Makita P-08361 gearbox. Refilled during initial assembly of the tool and recommended for maintenance

It is better if the lubricant is a branded product specifically designed for equipment of a certain brand. So, it can be lubricant for a Makita hammer drill or lubricant for a Bosch hammer drill. If you don’t have a branded lubricant and you can’t buy it, you can use inexpensive domestic lubricants.

It is very important that you have instructions for the hammer drill that you are going to lubricate. Naturally, if you own a Makita or Bosch rotary hammer, this should be an instruction manual for the equipment of these particular brands.

All gearbox parts should be completely cleaned of old grease.

After carefully studying the instructions for the hammer drill, you can begin the procedure for lubricating its gearbox.

Before disassembling, the hammer drill should be thoroughly cleaned of dust.
When disassembling the gearbox, it is advisable to immediately remember how its structural elements are located in it. It should be borne in mind that it is not recommended to disassemble and lubricate the gearbox immediately after finishing using the hammer drill. This is explained by the fact that still hot gearbox parts, when exposed to a cold lubricant, may lose their physical characteristics.
After all components of the gearbox are removed from its housing, they should be thoroughly washed with gasoline or spindle oil and wiped dry.
The inside of the gear housing must also be washed, wiped (as far as possible) and allowed to dry completely.
When disassembling the hammer drill gearbox, you can pay attention to the fact that there is no lubrication on some elements of its design. This only means that such parts do not require lubrication and there is no need to apply it to them.
As mentioned above, it is better to use a branded lubricant for the gearbox of a drill or hammer drill, which has a number of advantages. In particular, branded lubricants retain their original characteristics much longer, so they can be used much less frequently. In addition, the proprietary lubricating composition has such an important quality as water resistance, so it effectively protects the metal parts of the hammer drill from moisture and, accordingly, from corrosion. As a good alternative to branded lubricants for the gearbox of a rotary hammer or drill, you can use Metabo oil, the cost of which is quite affordable.
After lubricating all elements, the gearbox must be carefully reassembled, observing the reverse sequence.

DIY repair

In a home workshop, repairing a gearbox is not so difficult. Repair comes down to disassembling the unit into individual parts, checking the integrity of their structure, purging and lubrication, followed by reassembly. The process is divided into the following stages:

Separating the gearbox from the engine and removing it (usually together with the chuck) from the screwdriver housing.
Unscrewing the housing and removing the locking washer.
Sequential removal of satellite gears and transfer plates (2 or 3, depending on the design).
Removing the ring gear and checking the ball bearings (they can roll around the entire seal, but should not roll out beyond it).

After removing all the parts, they must be cleaned of “old grease,” wiped dry and made sure that they are not damaged.

Then the craftsmen recommend folding them in the reverse order “dry” and making sure that when the satellites rotate, the chuck spindle also rotates. If the rotation is carried out without twisting, then it can be assembled back.

First, bearings are placed in the recesses in the housing, onto which the ring gear is installed. Then, one at a time, the transfer plates are placed, with the satellites installed on them, and the locking washer is placed on top.

Causes of equipment overheating

Many home craftsmen have a question about how to use a hammer drill so that its gear housing does not overheat. First of all, you should find out the reason for the excessive heating. One of these reasons may be too much lubricant in the internal part of the gearbox, which also negatively affects the performance of the device.

The reason for the intense heating of the rotary hammer gearbox may also be that an insufficient amount of lubricant is supplied to its internal parts. This can happen in cases where the hammer drill is used for too long in the chiselling mode.

Through this hole in the hammer drill body, lubricant is periodically added during operation.

Another common reason for the device to overheat is that the holes through which cooling air flows to the hammer drill motor are clogged. In such cases, it is necessary to thoroughly clean the rotary hammer from dust and switch it to normal drilling mode for a while. When operating in this gentle mode for about half an hour, the temperature of the gearbox housing should decrease.

With proper care of the technical condition of the rotary hammer and compliance with all recommendations for its use, the gear housing should not overheat under any operating conditions.

Design and principle of operation

The gearbox is a complex mechanical transmission unit through which the axis of the motor-power unit transmits torque to the cartridge.

Two or three transmission stages are installed in the gearbox

The design of the “household” dual-mode screwdriver assembly includes:

The plastic case is a small drum that is mounted on a cartridge. The body itself is fixed motionless, and the chuck shaft is inserted into a clamp on one of the transfer plates;
2 or 3 transfer plates (carrier) - a round metal plate, on one side of each there are 3 protrusions for small gears. On the other side of one of them there is a clamp for the chuck shaft, and the other (or 2 others) has another so-called. a “planetary” gear that rotates three small gears;
6 or 9 small gears (three each: they can be of the same or different thicknesses) are the so-called “satellite” gears, which are installed and rotate freely on the projections of the transfer plates. With their teeth they interact with the sun gear located between them and with the ring gear, which is located on the inner surface of the housing;
ring gear - a metal ring with teeth on the inside and small protrusions on one of the rings on the outside. It is placed on these protrusions and ball bearings on the inner surface of the housing.

The parts are lubricated, assembled in series and installed inside the ring gear, which lies inside the housing drum (it has a seal with recesses for ball bearings and gear lugs). After this, the surface of the open satellites is covered with a metal washer, in the center of which there is a hole into which the engine shaft enters with another gear attached to it.

During operation of the screwdriver, the gear wheel on the motor shaft rotates the upper satellites, and they, spinning around their axis and, along the ring gear, respectively, transmit movement to the next carrier. Depending on the number of plates and small gears, the rotation speed will decrease proportionally.

As can be seen from the design of the gear unit, they are divided depending on the number of transfer plates into:

two-stage.
three-stage. In this case, another plate with a “planetary” gear and 3 satellites is added to the design.

Reference. The number of speed modes of the device depends on the presence of stages, and this, in turn, will affect its cost.

Another indicator by which gearboxes are divided is the material from which their parts are made.

In the production of satellite gears the following is used:

plastic. Such structures are relatively lighter, but their reliability is lower than that of their metal counterpart;
metal. They are durable and with proper care and lubrication they will work like a clock.

Important. The disadvantages of metal parts are a continuation of their advantages - they are heavier than plastic ones and are more expensive. Moreover, if a screwdriver is used without violating the operating rules 2-3 times a year, the master most likely will not feel the difference in what material the gearbox parts are made of.

Proper care of a drill with a hammer drill function

A hammer drill is a hybrid of two types of equipment used to create holes in various materials. Unlike a classic hammer drill, this drill has some design flaws, which makes its maintenance more difficult and not very convenient. Such disadvantages include, in particular:

lack of a special container into which the lubricant is poured;
the difficulty of servicing the cartridge due to the peculiarities of its structure.

The main care for a drill with hammer drill functions is that after each use, the drill of such equipment (including the tail section) must be thoroughly cleaned of drilling waste, and before inserting such a tool into the drill, a small amount should be applied to its shank lubricants (you can use regular grease). If the amount of lubricant on the shank is excessive, it will not harm the tool itself or the equipment being used, but it may negatively affect the appearance of the surface you are drilling, as excess lubricant will splash out of the rotating chuck.

Impact drill gearbox lubrication

As a rule, drills that have the functions of a hammer drill are purchased for household use, since their price is quite affordable, and they cope quite well with their functions when performing simple repair work around the house. Despite the fact that these power tools differ in the features mentioned above, caring for a hammer drill does not take much time and does not cause problems even for not very experienced users.

Which hammer drill components need to be lubricated?

According to the operating instructions, the hammer drill requires lubrication in three zones. This will extend the life of the device and equipment, and facilitate the operation of the tool. Let's figure out what exactly needs lubrication and why.

Working equipment

Working equipment (drills and bits) inserted into the chuck are subject to enormous load. They receive from 1000 to 5000 blows per minute, transmitted to solid material, thanks to which the tool easily passes stone, concrete screed, brick and other obstacles.

The operating instructions instruct you to lubricate the drill shank before each use. If the hammer drill is operated during the day, the operator is required to periodically remove the drill and check the presence of lubricant on the shank. Without lubrication, the assembly will quickly overheat and break, which will require not only the purchase of new equipment, but also repair of the cartridge.

Lubricant for hammer drills is applied to the grooves (two or five, depending on the type), which are secured with locking wedges. You must first wipe the outside with a napkin to remove any remaining dust and dirt. The product is usually squeezed out of a tube. 1 g is enough for uniform application. When changing drills, bits and other equipment, lubrication must be done each time. After removing the drill or other device, the end should be wiped with a napkin so that it does not stain the suitcase and surrounding objects during storage.

Correct application of lubricant to the hammer drill.

Lubricant for drills reduces friction in the fixation system and extends the life of the drill shank (if this section “sticks together”, then even with an intact punching part with a Pobedit nozzle, the equipment will not be suitable for work). Hammer drill lubricant also protects against dust penetration, trapping it on itself. Small particles of crushed walls and other debris do not penetrate into the instrument.

Watch a video about lubrication of hammer drills:

Cartridge

When you buy a new hammer drill, its chuck is dry. The user needs to lubricate the entry point of the tool, since this is where the greatest friction occurs. This action will protect the assembly from excessive wear and dust penetration.

Gearbox

This unit is responsible for transmitting torque from the electric motor to the cartridge. Internal parts here are subject to increased friction when operating at high speeds and elevated temperatures. The mechanism also gradually becomes clogged with debris, dust and dirt. To reduce wear, manufacturers supply it with a special coating, but this is not enough for everyday work, so after a long period of operation it is necessary to disassemble the housing and apply lubricant to the gearbox. If you do not know how to do this, then the tool must be taken to a service center, where a specialist will perform this work.

The gearbox can be of two types:

1. With separate execution from the shock group . Here the reciprocating mechanism for making strikes is made separately. It consists of a crankshaft and a piston group that create a force transmitted to the cartridge. The system has its own lubrication. The gearbox is only responsible for the rotation of the equipment.

Rotary hammer gearbox with separate design from the shock group.

Lubricant selection

Before dealing with the question of how to lubricate a hammer drill, you should become familiar with the means that can be used to carry out such a procedure. As a rule, the manufacturer indicates the type or brand of lubricant that is optimally suited to the equipment of a certain model. In any case, such instructions are in the instructions for hammer drills produced under reputable brands. If there are no such recommendations, you can ask the consultant at the store which lubricant is best for the hammer drill you are purchasing.

Service centers use branded lubricants that are difficult to find in the store, but can be ordered if you know the product code

A universal and relatively inexpensive lubricant that can be used for most modern models of rotary hammers is oil poured into diesel engines. Compositions based on graphite are actively and quite successfully used to lubricate hammer drills. Such compositions, in particular, are used to lubricate open-type worm gears.

Litol-24 is also actively used as an inexpensive lubricant for structural elements of perforating devices. Meanwhile, such a lubricating composition can cause overheating and braking of rubbing parts, in addition, its effect does not last long.

How to choose a lubricant for a hammer drill?

Most often, the instructions for each device indicate the necessary lubricant for the hammer drill gearbox.
For example, for Makita rotary hammers there is a special lubricant P08361. Other compounds are suitable for Bosch. Branded lubricants have the required water resistance and prevent corrosion. If there is no information on how to lubricate the hammer drill, then you can use some other means. But you need to find out from the store consultant whether they are suitable specifically for your hammer drill. One of the most popular products is diesel engine oil. also quite good and is often used for open worm gears. Litol 24 is also popular, but this lubricant also causes braking and additional heating. Yes, and it works for a relatively short time, unlike branded lubricant for hammer drills and for cordless tools, it is extremely undesirable.

A few more recommendations for lubricating a rotary hammer

The question of how often a rotary hammer should be lubricated arises among users of such equipment quite often. There cannot be a definite answer to this question, since the regularity of lubrication depends on the intensity of use of the hammer drill, as well as on the loads the equipment experiences. In addition, you need to pay attention to the manufacturer’s recommendations, which must be indicated in the technical data sheet, as well as whether the warranty period for the device you are using has expired.

Hidden surfaces of gearbox parts must be lubricated before assembling the mechanisms

The question of how to lubricate a hammer drill of one of the modern models is much easier to answer, since the vast majority of such devices are already equipped with a special container into which you simply need to pour the lubricant, unscrew the drain cap and drain the old lubricant. Before filling in new lubricant, the level of which should not exceed the control mark, it is better to blow out the container using any suitable compressor, and then rinse it with spindle oil or regular gasoline.
