Repair of the hydraulic cylinder

The machine – no matter if it is used frequently or rarely – must be operational. It also includes her hydraulic systems. Below you can read how to quickly and easily repair the most common damage to hydraulic cylinders.

No machine in agricultural technology can do without hydraulics. Typically, the sealing elements used there are of such high quality that leaks due to aging and wear are rather rare. If anything, the most common cause of failure is the mechanical damage to the piston rod ( . For example, a strong impact on the chrome beam is enough, and a small hole in the precisely finished surface already announces oil leakage.
Regardless of whether it will be a recess or a corrosive coating: grooved rings that are mainly responsible for sealing will not help. The cylinder begins to “sniff”. In addition, sharp burrs can cause an immediate cutting of the sealing edge of O-rings, which promises a decrease in performance and a more serious failure.
What to do when the hydraulic cylinder drips? The most professional solution is to go to the nearest repair service with a cylinder ( . This is a cliche because the result is often almost a new cylinder and a large gap in your pocket. Because such specialist repair shops are not available on every corner, sometimes you have to make way to go there. It takes valuable time. When ordering repairs, it is also necessary to predict the waiting time in the queue. And the machine is immobilized and the robot lies … Therefore, we encourage you to be brave – you can also regenerate the cylinder yourself! All you need is some skills, some tools, and equipment.
Here are some tips on how to repair a leaking hydraulic cylinder yourself. While the usual replacement of the seal is always successful, if it has been properly carried out, repairing the damaged piston rod is a bit more demanding. We will reveal a few patents from the construction machinery industry, how to use the appropriate masses that will replace metal losses. So – do it!
Opening the actuator

The cylinder seals are located in the cylinder head that closes the cylinder tube around the piston rod. The gaskets are also at the bottom of the piston ( . To get to the seals, the head must be separated from the cylinder tube. There are different ways of opening for different types of actuators. The most common construction is the head screwed on or inside the cylinder. You can talk about happiness if you can open this set with a hook key or a large pipe wrench. If it does not work, you have to try a few tricks.
