Hydraulic jack repair. Causes of breakdowns and their elimination

In order to repair a hydraulic jack as rarely as possible, you need to monitor the product and operate it correctly. Maintain the required level of liquid that seeps through the seals. Often, due to the entry of air, the load becomes jammed during lifting. Then difficulties arise when lowering it. In these cases, the jack needs to be disassembled and repaired. You can actually carry it out on your own, following a certain sequence of actions.

The hydraulic jack consists of 3 components:

• Cases.
• Piston.
• Working fluid.

At the beginning of operation, the mechanism is placed on a flat plane, the valve closes and the rod is raised due to the movement of the lever. When deflated, the valve opens and the pressure of the load returns the rod to its place.

When the lever is pressed, fluid is pumped from the housing into the cylinder, pushing it upward. The suction and discharge valves prevent its return.

When the valve in the pump opens, the fluid returns to the housing space.

Bottle products

Bottle jacks have the ability to lift loads ranging from 3 to 200 tons. This is ensured by the presence of a large support plane.

There are 2 types of bottle machines:

• Single-rod. Due to their ease of use, they are used in mechanical engineering and construction. The jack is used by car enthusiasts to lift cars. Used as a unit in a pipe bender or press.
• Double-rod. Works in both vertical and horizontal positions. The device includes 2 rods. They are lifted by a cylinder.

Roll-up view

Externally, it is a cart mounted on wheels. Before work, it rolls under the lifted load.

The design is large in size, so it has found application in tire shops. Lifting is carried out by pressing the lever. When the valve opens, the stem moves down.

If a slight lowering is required, a tubular handle is used. It fits onto the valve screw and rotates it around its axis. A slight decrease in the rod begins.

This type of product has disadvantages:

• Large dimensions and heavy weight of the product.
• Availability of a concrete or asphalted area.

Types and causes of breakdowns

Repairing a hydraulic jack is done by yourself. To do this, all possible malfunctions and rules for eliminating them are studied. Parts are prepared in advance to replace failed ones. The main causes of breakdowns and the rules for eliminating them are known. To do this, you need to have the right tool at hand.

Hydraulic cylinder malfunction

If the hydraulic cylinder malfunctions, the oil reservoir must be removed. First the piston is disconnected. To do this, use wrenches to unscrew the screws located in the upper part. The protective rings are removed and the reservoir is pulled out. If the cylinder is damaged, it must be replaced. During installation you will need a clamp. The bolts removed from the jack are replaced with new ones. They are selected the same size. If the removed bushings are worn out, new ones are installed. Some models allow the use of the round type.

Overhang of the upper and lower rings

If the top ring flies out, the top plate is disconnected. It is first inspected for defects. The screws are unscrewed using keys. It is important to inspect the piston to make sure that the broken ring has not damaged it. After this, install a new one on the rod. In order to improve fixation, you should use a sealant.

If the lower ring flies out, the lower frame is removed. In this case, the hydraulic cylinder is inspected. Its integrity is checked. It is important that the piston moves smoothly without jamming.

To remove the frame, the jack is turned over and securely fastened. The cover is removed only after the sealing ring has been inspected. Using a screwdriver, the retractable extension is dismantled. It also requires inspection, since there is a risk of it being damaged by the ring.

If it is replaced, the markings that are stamped on the case or written down in the documentation are specified.

During installation, the rod is lubricated with machine oil. A new ring is also being installed.

Broken traction lever

The difficulty of such a repair is that it will require removal of both the traction device and the cylinder. First, the top cover is removed and the cylinder is inspected. There may be scratches on it. Sometimes the moving plate also requires replacement.

The cylinder is removed using a clamp, and the top plate is supported by rods. If the design contains several pistons, then removal of the coil is also required.

The traction device with the connected lever is located on the bottom plate. To remove the lever, use a hammer to release the rod. At the last stage, the lever is fixed to the draft mechanism.

Broken wedge grip

In the event of such a breakdown, the top plate is disconnected. To do this, unscrew 4 screws. Using a screwdriver, pry up and remove the tie. It is located near the oil system.

Then the grip, which is located on the rod, is removed. Before installing a new one, the stove is inspected. Assembly is carried out in reverse order.

Removing the jack plate

When repairing such a breakdown, the piston system is first checked. It may be damaged. Depending on the type of jack, the plate is secured with different bolts. As a rule, they have an M6 thread. There are 4 of them, and they are located along the edges. When replacing the plate, you should also check the oil system, since it may also be damaged.

Replacing the hinge

This type of repair is easy to do yourself. To do this, unscrew the bolts and remove the top plate. After this, the rod is disconnected, the loop is easily removed. It is often bent. Using a machine, its surface is leveled. In case of large deformation, it is better to replace such a product with a new one.

The fitting is not working well

This failure is directly related to poor pipeline performance. It is necessary to inspect the piston system. Due to its malfunction, the fitting experiences increased pressure. To do this, the piston assembly is dismantled and damage is looked for in it. If possible, it is eliminated. Otherwise, this part of the jack must be replaced.

Troubleshooting a pipeline

These types of repairs are carried out by service centers. At home, you can inspect the unit and make only simple repairs.

To do this, the bolts are unscrewed and the top plate is dismantled. Using a screwdriver, the tie is undermined and then removed. If an external inspection shows that the top nut is broken, then it is impossible to repair such a breakdown at home.

Repair rules and selection of spare parts

Repairing a hydraulic jack begins with disassembling it. All parts of the product have threaded connections, so you should be armed with wrenches.

The work sequence is as follows:

• The oil needs to be drained. A special container is prepared for this.
• The piston and valve are removed. They are undergoing a visual inspection. All dirt and rust are cleaned off.
• The cause of the malfunction is a deformed rod. The jack cannot lift the load. In this case, the part needs to be replaced.
• Gaskets require careful inspection. If no defects are found during an external inspection, it is still better to replace them. Often microscopic flaws are not visible, but they are the cause of the malfunction.
• The oil valve is checked. Sticky dirt is removed. Due to its presence, the ball is in the wrong position and oil leaks.

All parts of the disassembled device are washed in a special liquid. Defective parts are replaced. For this purpose, spare parts are being selected. All new structural elements must have the same parameters. Repair kits are available to replace a small structural unit. They include parts and gaskets between them. Assembly is carried out in reverse order.

Oil replacement and filling rules

Before adding new oil, the old oil is completely removed. If there is flushing liquid there, it is also removed.

Before pouring a new one, all present air is eliminated. The outlet valve opens and the device goes down. Then you should carry out at least 5 pumpings. The bolt is removed from the filler neck and oil is poured through the nozzle to the required level. Then the pumping is repeated and the oil is refilled. It is important to remove all air from the system. As soon as the oil surface stops bubbling and reaches the desired level, the jack is ready for use.

Operating rules for jacks for 5 and 12 tons.

If you use the jack correctly, the number of breakdowns will sharply decrease.

To do this you need to adhere to the following rules:

1. Lifting loads that exceed the permissible limit is prohibited.
2. The work is carried out smoothly, without jerks.
3. Installation can only be carried out on a flat surface.
4. Before work, all moving joints are lubricated.
5. An external inspection of the device is carried out to detect cracks or oil leaks.
6. The oil level is checked and must be brought to normal.

To keep your hydraulic jack running smoothly, it requires monthly maintenance. Since the product is constantly under heavy loads, all parts require lubricant. It is important to prevent the presence of dirt, which leads to jamming of the device. The device is stored in a lowered position.

A jack is a special device that is used to lift heavy loads and fix them at the desired height. The use of this mechanism is indispensable when repairing a car during the process of changing a wheel.

A hydraulic jack is considered the most convenient and effective when performing various types of work. The working force is achieved thanks to a piston, which is driven under pressure generated by hydraulic oil. However, during operation, the equipment may fail. You can assemble the device and repair a hydraulic jack yourself at home.

Operating principle of a rolling jack

Rolling jacks are a type of hydraulic tools. To make the body of the device, durable metal elements are used, onto which wheels are attached for transporting and moving the jack. A lifting mechanism and a hydraulic cylinder are installed in the hole on the body, thanks to which the platform rises in a horizontal position during the extension process.

The hydraulic jack is put into operation by swinging the lever, and lowering it by turning the valve screw. When the weights are lowered onto the upper part of the valve screw, the tubular handle is mounted, after which the entry of the partition into the groove is noted. Rotation of the handle around its axis allows you to directly rotate the screw itself. As a result of this, there is a release of pressure that is in the hydraulic cylinder, after which the load is lowered to the desired height. Thus, when performing simple movements, the car is raised and lowered.

Types of hydraulic jacks

There are various rolling hydraulic jacks on the market that are used for personal purposes when repairing cars whose weight category does not exceed 3 tons. However, there are also more professional models. Often such devices are equipped with pedals that allow for preliminary lifting. These types of equipment are most often used by car service centers and tire stations. This device is used to lift loads up to 4 tons, and makes it possible to complete the job faster.

There are also models of jacks that make it possible to lift loads of up to 20 tons. At the same time, they are equipped not only with a pedal that allows for preliminary lifting, but they also have a special sliding crossbeam, which is designed for servicing heavy machines and special equipment. This mechanism has a number of disadvantages, including its bulk and size, which complicates its transportation in a car. When working with such a device, you must have a flat horizontal surface, for example, asphalt or concrete.

Repair of a rolling hydraulic jack: process features

To carry out repair work, the following will be required:

• wrench;
• containers into which the oil will be drained;
• kerosene;
• oils

While using the jack, the tool may break. As a rule, when malfunctions of this equipment occur, oil begins to leak, the tool jams when rising to a height or, conversely, when lowering. If such defects are detected, it is imperative to repair the device.

If the cause of the breakdown is an oil leak, then first of all you will need to disassemble the jack, remove the pistons and check them for corrosion. After that, all dirt and resulting corrosion must be completely removed. Then you need to check the stem.

If the element is bent and deformed, then we can talk about the impracticality of repairing this jack.

When repairing a valve that allows oil to pass through, it is necessary to unscrew it and check whether there is dirt or deformation there. If deformation is present, the valve must be replaced. If it is slightly contaminated, leakage of the working fluid will be observed, since the ball will no longer fit tightly into the seat. To eliminate this, first of all, you need to drain the old working fluid (oil) into an empty container and pump the system completely by raising and lowering the lever.

After this, it is necessary to rinse each part from adhering dirt and remove any remaining old working fluid. It is imperative to replace all cuffs, as well as sealing gaskets. If it is noted that dirt has hit the working part, then it must be removed by first unscrewing the housing head.

After that, it is necessary to pour kerosene into the base of the jack and bleed the equipment. To do this, the locking needle must be unscrewed. After all manipulations, kerosene should be removed and clean oil should be poured into the working part.

It is worth noting that the performance of the jack after cleaning may decrease slightly. This is due to the accumulation of air bubbles in its working part due to insufficient oil.

If such a situation is observed during operation, then repairs must be carried out according to the following principle. First of all, you need to open the plug on the oil tank and loosen the bypass valve. After this, pump the pump on a hydraulic press at a rapid frequency in order to move air from the working part to the container where the oil is present. Then you need to close the hole on the oil tank and tighten the bypass valve. If the manipulations were performed correctly, the jack will work as before. If there is residual air, the work must be repeated again.

If the jack does not work properly or the lifting of loads is carried out extremely slowly, then you can use another method of removing air from the working part.

To do this, the locking needle must be turned 1.5-2 turns. After this, lift the plunger by the screw to the uppermost value mark. Next, it must be lowered to the lower position. Each action must be repeated in a circle about 2-3 times. You can prevent similar problems from occurring in the future by periodically checking the oil level in the working plane of the jack and adding it if necessary.

A jack is one of the most important tools in your arsenal; it will help you everywhere: repairing a car or equipment, carrying out a variety of construction and repair work. And if suddenly your device fails for some reason, you need to find out how to repair a hydraulic jack yourself!

You will also be pleased with the wide variety of jacks, each of which has its own characteristics and distinctive features.

• The most famous is the mechanical one, the main advantage of which is considered to be low cost. Additional advantages are: low weight, high lift level and fast working stroke. Among the disadvantages, the small support area is noted, which leads to little stability.
• The next type is electrical equipment, it works from the electrical wiring of the machine, and the jack is controlled using a small block. The load capacity of the device reaches 2 tons, but the disadvantages include the large mass of the device and manual lowering, which requires a lot of time.
• There is also one that runs on compressed air or a compressor. The advantages include low weight, reduced work costs, and a large support area.
• But we will pay more attention to the hydraulic jack, because this model is most often used not only when repairing a car, but also during construction work, including work with reinforced concrete and reinforcement structures. They are able to demonstrate the highest possible performance, because the efficiency of the device reaches 80%, and the load capacity is about 200 tons, depending on the model. Unfortunately, we cannot do without difficulties. For example, you cannot precisely adjust the release height, so you should study the operating instructions for the tool in advance. During operation, in order not to cause the jack to break, it is advisable to monitor the condition of the oil seal, valves and the presence of oil. Yes, and you need to transport the tool wisely - only in a vertical position, so that the fuel does not simply leak out through the valve.

Like any equipment that carries enormous loads, devices can often break down, and therefore you always need to know how to repair a jack yourself. To be fully armed at the moment of breakdown!

There are some other considerations, including the need to change the oil. However, any repair is carried out practically according to the same scheme. And the first thing you need to know is how to disassemble the device, after which you can start replacing the fluid. Disassembling the tool is carried out in the following order:

• Using wrenches, unscrew the fasteners;
• Remove the fluid bleed valve and piston;
• Carrying out a proper inspection, we check the quality of the valve and all gaskets - if you notice that they have become unusable, we simply change the elements of the jack;
• We clean the mechanism from debris and other foreign elements, rinse the cylinder;
• We check and change the old rubber if necessary;
• The last step is to reassemble the tool in reverse order.

Naturally, after you assemble the jack, you should definitely check it for functionality! If the device starts working, great, but it’s not always possible to fix everything the first time. Perhaps the whole problem is in the oil?

Oil is the driving force of the device; it is the oil that presses on the piston, setting the rod in the desired position. Due to this, it is possible to lift almost any load. If there is not enough oil in the device, the mechanism will not work. Many who start repairs for the first time skip this point, which ultimately leads to problems with the operation of the jack. Oil change instructions:

How to fill oil into a jack - step by step diagram

Step 1: Flushing the mechanism

In order to fill the jack with oil, you must first unscrew the plug and drain the old fluid. The next step is to clean the mechanism using washing liquid, which can be purchased at any hardware store. By the way, it is quite difficult to completely wash the jack, especially for a beginner, because you will have to fill in the liquid at least two or three times, after which it is pumped, the liquid is added again and pumped again. Draining the old oil is done in the same way - so that not a drop of old fluid remains inside the mechanism.

Step 2: Adding Oil

The container must be filled with oil completely, that is, until the liquid reaches the required level. At the same time, install the jack in a low position. To lower the rod to the lower position, be sure to turn the valve screw until it reaches the “drain” position. After tightening the plug, we pump it five times, after which we add oil and tighten the plug again. During the cleaning process there will not be enough oil every time, and therefore it is necessary to pump until the “fuel” of our jack reaches the required level and bubbles stop appearing on the surface of the liquid.

As you have seen, repairing jacks yourself is a fairly simple job. However, of course, you don’t want to bring it to repair work, because this requires both time and effort to implement. That is why we have compiled a selection of recommendations from experts for you. If you follow them, the operation of your jack will become much easier, and repairs can be “pushed” further away.

• In order for the oil change work to proceed efficiently and correctly, it is necessary to remove any loads, and the device itself can be started to be used only after you have completely completed all the work and assembled the jack;
• It is advisable to replace the “fuel” twice a year, and if you use the jack constantly, then at least once a month you need to carry out this work, and you must wash the entire mechanism every time;
• You can choose any oil, but if you are going to use the device in the winter, be sure to use a synthetic solution. This will allow the mechanism to always be in “full combat readiness” for work;
• Regardless of what time of year it is outside, it will be better if you can store the tool in a dry and warm place, otherwise the oil may simply freeze;
• If it is necessary to carry out work in the winter season, remember that working in the cold for too long can lead to damage to the device, and therefore the use of the jack is possible in the most extreme cases and for a short time.

If you work using these methods, you can significantly extend the life of the jack. And expensive repairs, which can cost you a significant amount, can be “postponed” for an indefinite period, which is good news!

Every self-respecting motorist knows at least a dozen ways to use a good jack. And the fact that wheels are changed with its help is already clear. One of the most reliable designs of jacks remains hydraulic, and it became available to a wide mass of motorists not so long ago. The fact is that the industry had previously produced only heavy-duty hydraulic jacks, which could only be used stationary or transported in trucks. These mechanisms were simply unsuitable for passenger vehicles. Their large weight, dimensions and large initial lifting level made their use possible only in pits and at special service stations.

Now the situation has changed greatly and there are many more jacks with hydraulics, and they have become different, both structurally and in size and load-carrying capacity. Now everyone can choose a jack in their weight category and in accordance with their needs. Now you don’t need to buy a huge five-ton mechanism in order to raise the front end of a small Daewoo. Such small models are compact, lightweight, fit into the trunk and can serve as a small press and a whole bunch of other jobs.

There are many types of hydraulic jacks, but if our favorite and only one is broken, we absolutely don’t care what you can buy in stores:

• rolling hydraulic jack;
• bottle;
• single plunger or double plunger;
• with electric or manual drive.

The principle of operation is the same for everyone, and repairing a hydraulic jack with your own hands should be carried out on the basis of knowledge of its fundamental design, regardless of the brand and load-carrying capacity.

Any hydraulic jack has a working fluid, oil, which has a very low compression ratio. For uninterrupted and stable operation of the hydraulic mechanism, periodic replacement of the fluid and cleaning of the system is required.

Depending on the load capacity class, the jack may have a two- or three-stage telescopic rod design. Jacks are often equipped with threaded extensions that allow the initial lifting height to be adjusted.

The working hydraulic part consists of:

It’s quite easy to figure out all this stuff, and we’ll start with the causes of the malfunction in the hydraulic part of the device.

Causes of hydraulic jack malfunction

The first reason for hydraulic failure is damage to the plunger and working cylinder mirrors. In this case, the device does not hold pressure, oil easily flows from the working chamber to the one above the piston, so such a jack simply either does not work or does not hold the load well. Damage to mirrors occurs due to the owner's negligence. Firstly, the jack cannot be stored and transported horizontally if the manufacturer has not provided for this possibility. The result is leaking working fluid, airing of the hydraulic system, and where there is air, there is corrosion.

Secondly, when corrosion appears on the mirrors of the working surfaces of the jack, the cuffs and seals immediately wear out - the rubber is not iron. As a result of this story, even more foreign debris, wear products of cuffs, and corrosion products appear in the oil, which leads to clogging of the oil passages and valves. Therefore, it is necessary to replace the fluid and flush the hydraulic system.

Repair of the hydraulic part of the jack

Hydraulic repair comes down to draining the old fluid, completely disassembling the jack and replacing the seals and cuffs. There is nothing complicated about this, since the jack does not require any complex adjustments, only diagnostics, maintenance and, if necessary, replacement. And all sealing elements and cuffs without exception must be replaced. We strongly recommend not to go to workshops and especially not to look for original seals - it is practically useless. The fact is that almost all sizes of hydraulic jacks, or more precisely, their seals, are standard and can be sold at any point that deals in consumables for tractor and automotive hydraulics. It will be three times cheaper, the main thing is to measure the rubber parts or take them with you.

Repair of rolling hydraulic jacks

A rolling hydraulic jack differs from a bottle jack only in its more complex mechanical part and hydraulics, which are designed to work in a horizontal position. If it is completely disassembled, the hydraulic part will have very minor changes compared to the vertical jack. The mechanical part is repaired as problems arise, and they can be expressed in wear of the lever-lifting system, wear of hinges and joints, as well as adjustments of the support mechanism.

After the jack has been repaired and assembled, it is necessary to remove air from the system and pump it with new fluid. The liquid is filled to capacity, after which the structure is pumped several times until the jack stably holds the rated load. After this, the system is checked for fluid leaks and the jack is ready for use. Lift weights carefully, and good luck to everyone!

DIY hydraulic jack repair

Any hydraulic jack is powered by fluid, and the main elements of the jack are the body, piston and oil. If you decide to learn how to carry out repairs yourself, you definitely need to know what reasons can lead to breakdowns. First of all, the design of the device could be “attacked” by corrosion, which leads to restrictions in the release of the mechanism. Naturally, jacks often break due to too much stress, which causes the rods to bend.

There are some other considerations, including the need to change the oil. However, any repair is carried out practically according to the same scheme. And the first thing you need to know is how to disassemble the device, after which you can start replacing the fluid. Disassembling the tool is carried out in the following order:
