Instructions for making a hydraulic valve for removing the engine with your own hands

Homemade crane for car engine

For repair work on a car engine, a lifting device was needed, a craftsman from Novosibirsk decided to make a homemade crane with his own hands.

As planned, the crane should be collapsible so that it does not take up much space in the garage. Lifting will be carried out using a hydraulic jack.

The photo shows the homemade design.

The base is welded from a 60 mm channel and a 50 mm square pipe; additional trim is used to strengthen the structure.

The channel is welded at an angle at which the vertical column tilts back.

Vertical stand and boom made of 50 mm square pipe.

The legs and reach of the boom are made from 40mm square tube. I drilled holes for the vertical stand, legs, and arrows for outreach. I welded the ear under the jack and figured out how the jack would fit on a piece of some kind of metal structure. The boom has a 30mm corner reinforcement.

Shoulder - 1/5, approximately 110 cm of the boom and 22 cm of the stop from the axis of the vertical post.

In the photo there is a rise of 130 cm to 210 cm. The boom can be moved plus depending on the load capacity. You can also unscrew the screw from the rod on the jack. The jack is designed for 3000 kg, so the weight on the boom is maximum 600 kg (arm 3000/5).

During testing, the vertical console began to bend (between the lower channels and the lower stop of the jack). Motor + gearbox, 250-260 kg. I had to strengthen it and weld 5 mm cut plates onto the 50 pipe.

A homemade crane is easy to use, 25 minutes and the motor is already on the cushions in the car.

Difficulties in making a lift

The cost of a finished car lift is high, but a self-made version can damage a person working under it if the design is unreliable. The weight of the car should not exceed more than a ton; if the structure falls on a person, irreversible injuries can occur.

A homemade car lift is made according to prepared drawings, or versions of finished products are used. In the latter case, one has to rely on the author's high computational skills. Incorrect calculation of the base or one of the fastened units can lead to irreversible consequences, at best, damage to the lifted unit.

Do-it-yourself hydraulic crane for engine removal: instructions and drawings

For full convenience of using your own garage, sometimes you need equipment for lifting heavy parts of the car. The best solution to this problem is a hydraulic crane. The unique structure allows you to rearrange small loads with little effort from the mechanic or car owner.

Design features and operating principle

The hydraulic valve is made of durable metal and has a stable design. The main principle of the mechanism structure: stable support with low dead weight. This helps you lift loads of up to three tons with ease, but a maximum of two meters above the ground.

Garage crane is used for:

• removing the engine;
• lifting beams, bridges;
• movement of dimensional units.

The crane contains a hydraulic drive and operates through a system of communicating vessels. The method allows you to make the rise smooth.

Stationary

The stationary crane is installed in large car repair shops and is securely attached to a monolithic foundation. The mechanism has a boom with a rotating system and is equipped with a manual drive. Allows you to work on only one vehicle at a time.

It is important to calculate the installation location in advance, since it will not be possible to dismantle the structure without loss.

An integral advantage of a stationary crane is its large lifting capacity. It is provided by a monolithic support, which creates rigidity of the system.

Portable

The hydraulic rolling crane has wheels on its base. The support is provided by the lower metal beams, which results in loss of load capacity readings. It is better to choose a faucet with a massive triangular support. By design they are divided:

• on cast solid supports with limited boom reach, but good load capacity;
• telescopic or folding - they have an increased boom reach, but reduce the load capacity by several times.

Important! Folding units need to strictly follow the instructions for lifting the permitted load. The arrow cannot withstand and, if the permitted standards are not observed, it breaks off.

Main types of equipment

The average garage has a reduced square footage and requires careful selection of equipment. Before installation, it is recommended to carefully study the need for individual mechanisms, their types, pros and cons. A hydraulic valve is determined by two criteria.

By type of drive

There are also two subtypes of hydraulic drive:

• automated design with hydraulic cylinders;
• combined, with hydraulic cylinders and manual winches.

A significant drawback of the first is oil cylinders. They need frequent regular replacement, so this design is considered extremely unprofitable for constant use. The combined system will last longer. However, some of the work with winches will have to be taken on by mechanics.

According to the design of the support

Hydraulic cranes are divided into mobile and stationary, they can be folding and prefabricated cast (goose). For ordinary garages, it is more rational to choose a mobile structure with folding parts.

What properties should a garage lift have?

There are two main requirements: stability and load capacity. Secondary requirements are the ability to move, rotating support, low support beams, folding mechanism. The properties required by the lift are calculated solely from the individual characteristics of the room.

DIY crane assembly technology

If you have certain skills, assembling the mechanism yourself will not be difficult. To do this, it is important to draw up a preliminary design drawing, choose materials wisely and strictly follow the assembly instructions.

Schemes and drawings

Below are sample drawings of a hydraulic crane. You need to make accurate calculations yourself, based on the parameters of a particular garage.

Material selection

To build a garage lift yourself, it is recommended to first purchase all the required materials:

1. 3 steel corners with parameters 7.5x7.5x0.8 centimeters.
2. “Worm” gearbox, the minimum load capacity of which starts from 300 kilograms, and the additional indicator is 60 kilograms.
3. A strong steel plate one centimeter thick. If you have an old metal cutting machine, you can take it from it; you won’t need outside help for this.
4. About 10 matching bolts.
5. 2 dense metal chains with a diameter of two to three centimeters. The crane is designed to work with very heavy materials - you should carefully monitor the quality of the metal.
6. Hook.
7. Steel cable with a diameter of 5 millimeters.
8. 2 keys with different parameters in the shape of an asterisk.

Step-by-step construction instructions

The process of assembling and installing a homemade garage crane does not look complicated:

• steel corners must be installed on parallel walls;
• fasten the steel plate to them using M8 bolts;
• fix the “worm” gearbox on the plate;
• install a larger key on the drive shaft;
• drill a hole in a pre-designated place, insert a chain into it and close it into a ring;
• fix a smaller key on the output shaft of the gearbox;
• drill 2 more holes in the plate;
• pass the second chain through the holes, where one end is on a small key, and a hook is installed on the second.

Installing a faucet yourself has a number of important advantages. For example, the cost of a homemade mechanism is almost two times lower than a purchased one.

What types of lifts are there?

Lifts come in various designs, differing in the method of lifting the car and the type of drive. For vehicle repairs, three types of drives are mainly used:

• chain mechanisms;
• screw;
• hydraulic systems.

The method of lifting the car plays an important role in the design; a garage lift can be a fork, scissor, or platform design. The most popular are fork screw units, the basis of which is a long threaded shaft made of tool steel. The parts of the unit are able to withstand the load of an average car; it is almost impossible to make the mechanism with your own hands, due to the complex design of the forks.

Types of lifts for car repairs

The easiest way to make a platform lift with your own hands is using a screw mechanism.

Parallel beams attached to the mechanism are capable of lifting a car weighing up to 3 tons.

How to remove the engine from a car in the garage with your own hands?

Basic maintenance of the motor is possible without dismantling it. Replacement of spark plugs, maintenance of intake and exhaust manifolds, and even replacement of the timing belt (chain) is carried out directly in the engine compartment of the car. However, work with valves, crankshaft, piston group, etc. is carried out only with the engine removed. Not to mention the overhaul procedure.

From our article you will learn how to remove the engine from a car in the garage, how you can remove the engine yourself and how to do it correctly.

The material was prepared by the site Auto-science.ru - whose specialists will help you check the mileage of your car efficiently and without errors.

How to remove the engine from a car in the garage without resorting to the help of a car service?

In fact, this is not such a complicated procedure as it might seem at first glance. The main task is to select tools for removing the motor.

Important! The engine weighs several hundred kilograms. Falling it can not only cause property damage, but also cause serious injury.

Before lifting the engine from the engine compartment, it is necessary to carry out the following procedures:

1. Drain all technical fluids: oil, power steering fluid, brake fluid.
2. Free the cooling system from antifreeze.
3. Drain the gearbox (except when you remove the engine without removing the gearbox).
4. Disconnect all hoses and pipes of the fuel, brake, lubrication and cooling systems.
5. If possible, remove attachments: air conditioning compressor, generator, etc.
6. Disconnect electrical cables, engine control unit, injector control cables, high-voltage ignition coil wires.
7. Remove the connectors from all motor sensors. It is recommended to make a list (“based on” the maintenance and repair instructions), this will help you not to miss a hidden connector.
8. In most cases, you will need to remove the hood cover.

If you plan to remove the engine without the transmission, you need to unscrew all the tightening bolts and make sure that after removal the gearbox will not fall under the car. That is, you need to take care of temporarily securing the unit.

How to remove the engine from a car?

At home, there is usually no professional lifting equipment, so you will have to rent it or make it yourself.

Do-it-yourself goose for removing the engine

This is a simple mechanism that resembles a gooseneck. It makes it possible to move the engine away from the engine compartment. It may have a rotating design that allows you to remove the engine without moving the machine.

The heavy internal combustion engine is simply transferred to a workbench located next to the car. In fact, it is a universal garage crane. The rack rests on long “legs” located under the engine compartment to prevent it from tipping over. A cable and a winch are used for lifting.

The gander is used both in garage conditions and in small services.

DIY engine removal lift

As a rule, this is a rolling crane, the lower part of which is placed under the front bumper. A smooth platform is required; on uneven ground, removing the engine using such a device is problematic. The lift operates using hydraulics or a tensioning mechanism like a winch. The device is simple: a stand with rolling supports, and a movable boom on which the motor is suspended. You can make a lift with your own hands from a channel or a square professional. pipes.

If there are strong wheels on supporting legs, you can quickly roll out the lift with the motor and move it to the repair area.

Do-it-yourself winch for removing the engine

Applicable if the car is being repaired in a solid stone garage. The most inexpensive tool that can be used to remove an engine. A chain or cable is used to pull it out.

There are two design options:

• A transmission mechanism with a drum that is suspended from the ceiling.
• The winch is fixed to the floor, and a pulley is fixed under the ceiling.

Features of removing various motor designs

Longitudinal arrangement. As a rule, such internal combustion engines are removed without a gearbox, although exceptions are possible. The radiator needs to be removed.

Transverse arrangement. The motors are compact and easy to lift vertically. The gearbox remains on the engine.

Hybrid systems and electric vehicles. Internal combustion engines in such machines take up little space or are absent altogether. Electric motors can be built into the wheel drive or integrated into the transmission. Due to their small size, their dismantling is not difficult.

All types of internal combustion engines are installed on supports. In frame structures, the attachment points are located on the frame; in cars with a monocoque body, there is usually a subframe.

Choosing a design

Let's look at how to make a car lift. This device is used to fix the car and lift it to a certain height to provide access to the chassis, suspension, and mechanisms of the car.

First, choose a lift layout. The most popular devices are those with 2 stands. This design can have an electromechanical drive. There are designs with several racks; they distribute the load better. The scissor design is a platform with a lever system.

This device may have an electromechanical drive that will transmit the load. When making a homemade lift, you need to ensure that the device is safe and securely holds the car. It must be taken into account that when performing work, the master will be under a machine whose weight exceeds a ton.

how to lift the engine out of a car with your own hands

You really can't do it with your hands.
manual winch

head removed, hinge, 2 bolts, rags for wings, 2-3 meter thick pipe, 2 lift, 1 coordinate, do not put legs

You can take everything apart under the hood. I've already done this.

the cable, the crowbar, and two people can pull it out entirely. if there is one then for parts

There are special attachments sold in auto parts stores, where you can turn the handle by hand or something like that…. Well, personally, how long ago was the engine removed from a Muscovite - they drove it into the garage, the chain to the engine, then the chain was thrown over the crossbar, and then this chain was attached to the second car

depending on what car. on a six without a head, one was pulled out and installed. hard, but tolerable

at least three of us are required or a winch behind the beam

If a car has up to 2 liters, remove everything from the engine, the block will become much lighter. The engine jack is lifted, removed from the cushions and pulled out. If it’s a Jeep/SUV, then pull the waist, or take everything off again and take two or three people out. If it’s a BelAZ, then it’s easier to squeeze it out without special ones. equipment

I knew one guy - one of them pulled out pennies from the collection.

When the time comes to overhaul the engine, there is no way to do without overhauling its internal parts. To do this, you have to remove it and take it to a mechanic, who can replace all the old worn parts with new ones. But it is at this stage that most drivers make their mistakes when they try alone to quickly remove the engine, repair it and quickly drive their favorite car. First of all, you need to understand that it is impossible to remove the power unit alone, otherwise you can not only hopelessly damage the engine crankcase, but also damage your limbs. How many cases have there been when drivers, in great haste, tried to remove the engine themselves! Then we drive the car to the garage, where there is a pit and reinforced concrete floors, which allow us to more confidently carry out all these necessary repairs. You can only disconnect all the electrical cables, fuel wires and belts from the pulleys, while not forgetting to drain all the water from the radiator and the oil from the engine crankcase. These are all elementary but necessary operations that every self-respecting driver should know. Therefore, before removing the engine, you need to prepare all useful containers where all liquids from the engine will be drained, not forgetting to prepare soft rags along the way, with which you will have to collect all the spilled liquid (you can be sure that there will definitely be some). It is advisable, if the engine still has a liquid air filter (they are installed on GAS), to remove it and pour out the old oil. This will reduce the weight of the engine. Then we rent a special device - a jack-trolley and place it under the engine. With its help, we slightly lift the engine from below in order to be able to loosen the bolts on the rubber pads on which, in fact, the engine hangs. After the last nuts are unscrewed, the engine is then smoothly and gradually released to the bottom. This first option is suitable when an electric lift is available and the car can be raised completely. But in widespread cases, when you don’t have a hoist or floor lift at hand, but you really want to go, you can get by with primitive devices. You need to prepare a metal cable and pipe. Then we wrap the cable around the engine, lift the engine, loosen the nuts on the mounts and very carefully lower the engine to the bottom of the pit. It is better to do this dangerous work with three people, because two will hold the iron pipe, and the third will loosen the nuts on the engine shock-absorbing mounts. Needless to say, before removing the engine from the car, the wheels should be firmly fixed in wooden blocks in order to completely eliminate even the slightest movement of the car chassis? Install the engine in reverse order.

A winch or assistants to help.

Lower into the pit, then winch up

the simplest and cheapest option is a manual hoist. You can buy it for 3-4 rubles! https://www.mp-u.ru/shop/ruchnaya_tal

My husband also suffered and finally bought a hoist. Perhaps you should buy or maybe repair the old one. There are also spare parts for the hoist here.

What will you need?

If you decide to make a lift for your car yourself, then first of all you will need a drive mechanism and a stopper. These design elements can be found in specialized stores that sell similar equipment, or in enterprises that are discarding old but working machines.

If you decide to make a scissor lift, then you should select two hydraulic cylinders of appropriate power and length. Autolifts of this type are very difficult to equip with a reliable and safe locking system. Otherwise, their production is easier than the creation of lifts of alternative designs.

It is worth noting that installing stoppers on platform or fork lifts is much easier than on scissor lifts. To do this, an oblique steel strip and a retainer with a thickness of 2-3 centimeters are enough. When starting to manufacture or operate a homemade lifting mechanism, remember that you are relying on the reliability of the structure you created yourself, so carefully check the functionality and integrity of all its parts!

Equipment for removing the engine from a car

Removing the engine from a car is done in case of replacement and repair of car engine parts. Before removing the engine, it is necessary to move the machine to an overpass or inspection pit.

Lifting of the device is usually done using talc or another lifting device, such as a motor support. Since most engines are designed in conjunction with a gearbox and clutch, it is more convenient to remove the entire unit. The result of the technical condition allows you to determine the need to remove the engine from the car. In case of serious technical problems with the car, various repair equipment will be needed one way or another.

The procedure for removing the engine from the car

• We remove the hood; if the power unit is removed downwards, the hood does not need to be removed;
• Drain the antifreeze;
• Drain the oil from the engine;
• Disconnect the wires of all electronics;
• Disconnect the brake booster hose;
• Disconnect the fuel supply hoses;
• Disconnect the throttle and choke wires;
• Disconnect the clutch hydraulic cylinder or cable drive;
• Disconnect the muffler intake pipes;
• We fix the motor on the lifting device;
• Unscrew the fasteners to the body;
• We remove the engine; after the work, assembly is carried out in the reverse order.

Before disassembling the engine, it is necessary to carry out mandatory external cleaning on a stand specialized for these tasks. The stand allows you to rotate the motor at different angles for convenient washing and disassembly and assembly work. In order to ensure long-term operation of the car and the engine itself, all unusable parts are replaced with new ones.

Worn parts are marked for future replacement. The parts that most often become unusable are: pins and connecting rods with covers, pistons, liners, flywheel with clutch, crankshaft, cylinder block, bearing caps.

In conclusion, we can say that removing the engine from a car is a serious and lengthy process and is considered inappropriate without preliminary and accurate diagnostics.

Mechanism with 3-leg shoe

It’s easy to assemble a device with a shoe on three supports with your own hands. In this situation, a U-shaped base is prepared. After this, it will be possible to secure the pickup. For this purpose, numerous experts advise using a clamp. The hydraulic mechanism can be directly determined on the screws. However, it should not cover the supports.

Next, to make a car lift with your own hands, you need to fix the regulator. To do this, a small plate is cut from an iron sheet. It should be welded at the top beam. The distance from the edge should be at least 2.2 cm. After this, the shoe is strengthened. The first base is installed at the hydraulic device. At this time, 2 other supports should be placed at the front edge of the model.

Using a lift

The worm system should be operated in the following manner. Move the car about one size deeper into the room to make room for the table.

The operating principle is not particularly complicated:

1. Be sure to remove the bolts holding the engine and frame of the machine.
2. Place loops of steel rope under the motor and throw the ends onto the hook.
3. Start searching the chain. Over time, the movement will transfer to the drive shaft, it will force the loading shaft to move and tension will occur in the cables. The engine must be lifted slowly and carefully.
4. After pulling out the motor using a lift, stop operating the crane. The weight of the lifted load will now be securely held by the regulator.
5. Move the car and install in its place a strong table that can withstand a significant load from the motor.

Note! Use a durable table that can withstand heavy loads. It is preferable that it be on wheels for more convenient movement in any direction.
