A hydraulic jack is used for all jobs where the load needs to be lifted to a slight height.
Most often seen in locksmith shops, construction sites, equipment repair shops.
But, as in any other mechanism, failures occur in its operation, and then the repair of the hydraulic jack is inevitable.
The unit runs on liquid, so the main malfunction of such a lifting mechanism is oil leakage. Due to insufficient oil, air enters the working cavity, which slows down or makes the operation of the lift impossible.
Problems can be solved in one of three ways:
- contact the workshop;
- do-it-yourself hydraulic jack repair;
- throw away the old mechanism and buy a new one.
Most often, the easiest and least expensive way is chosen - self-repair.
For clarificationthe reasons for the breakdown of the jack must be disassembled. The old liquid is drained into a specially prepared container. Next, you need to remove the pistons and examine them for the presence of rust.
The most important part in the construction of jacks is the stock. It is checked for curvature. If there is deformation, then it can be stated with certainty that the repair of the hydraulic jack is impossible.
It is necessary to examine the valve that passes the oil. It can also fail due to mechanical deformation. In this case, it is replaced with a new one. But more often than not, the valve is just dirty, the ball is not sitting tightly in the seat, which is why the fluid leaks.
After disassembling the jack, thoroughly wash all parts to remove any remaining dirt and oil.
The used oil must be drained by pumping the system with vertical movements of the lever.
If there are cuffs, gaskets and other sealing parts, they must be completely replaced with new ones. What is it for? Any previously used gasket already has a defect, even if it is not visible, which will definitely appear when pressure increases.
Fresh oil is poured. This completes the repair of the hydraulic jack.
Important. Before assembling the jack, it must be pumped. Bleeding will remove any remaining air from the system. If you forget to do this, the performance of the mechanism will drop, or it will not work at all.
If you are not completely sure that youif you manage to carry out a quality repair - take the device to the workshop.
Repair of hydraulic jacks is a troublesome business, so only specially trained people will carry out repairs with high quality and with a guarantee of this quality.
And in the end - advice for motorists. Who else but they use jacks more often than others. So, you should always have it with you. Which jack to choose?
It will not be difficult to buy a car jack if you apply the following algorithm:
- determine the load capacity;
- select the maximum lifting height;
- take into account the pickup height;
- select drive type;
- choose a brand.
Having understood all the details and subtleties, you will work out the right decision and easily select the appropriate option.
