How to remove piston from cylinder rod?
You can remove the piston from the rod assembly by loosening the lock nut. Next, slide off the end cap and gland assembly. Once that is complete, remove the seals and inspect the parts, including polished parts such as the cylinder tube, rod, and piston.
What happens if you force the rod out?
If you try to force the rod out when resistance is met, the ring could jam and the cylinder may be damaged. Once the rod has been removed, the removal ring should also be removed and now you can remove the locknut, piston, and head/gland. From there you can access the seals, which should all be inspected and replaced.
How to remove wire ring from cylinder?
For a wire ring cylinder, the rod assembly should be retracted and the external steel wire ring removed . A mallet and punch can then be used to push the head into the cylinder tube until the internal groove is exposed and the internal wire ring is moved into a position to be removed.
What is a seal replacement kit?
The seal replacement kit for the cylinder includes a plastic removal ring, which should be straightened and then inserted in the internal groove with the feathered end pointing into the tube itself. If the ring is not entirely within the groove before the rod is pulled out, it may get stuck and become trapped between the tube and the head (which is certainly something to be avoided). If the ring is not in the groove, it may be necessary to remove it and try again.
What does it mean when a rod seal is bent?
The rod seal should also be checked for distortion, which normally is a sign of a bent rod or a worn-out guide bushing. If the inside of the tube is scratched, scored, or pitted, it will need to be honed or, if the damage is too deep into the surface, replaced.
What to do if you disassemble a hydraulic cylinder?
If you disassemble the hydraulic cylinder as a part of repair, inspect not only the failed part but also perform a thorough inspection of all other hydraulic cylinder components.
What is hydraulic cylinder?
Hydraulic cylinders take a significant part of the entire hydraulic system. They are mechanical actuators that provide the unidirectional force. Integration of hydraulic cylinders will eliminate the presence of levers and gears. Both mobile (front end loaders, hydraulic lifts, construction vehicles, tractors, auto cranes,) and industrial systems (hydraulic presses, agricultural machines, marine equipment, forges, and packing machines) utilize hydraulic systems. Among them, most of the applications use hydraulic cylinders for lifting, sliding, picking and gripping.
Can you replace hydraulic seals?
For hydraulic cylinder seals replacement, don’t measure the existing size of the seal. It will expand or compress according to the environmental condition. The best option to replace seals is to contact your hydraulic equipment manufacturer and order a proper seal kit for the particular cylinder you need.
Can metal tools scratch cylinder rods?
Metal tools will scratch the surface of the cylinder rod or cylinder barrel and will create problems like corrosion. So always choose the best-fit tools for repairs.
What Causes the Breakdown of a Hydraulic Cylinder?
There are many causes that can contribute to the breakdown or leak down of your hydraulic cylinder. Your hydraulic piston seals can simply be worn down in old age with time, affecting their effectiveness to the point that they fail to maintain a full seal.
Can you disconnect a hydraulic hose?
Once it is clean, you can disconnect the hoses and both ports and hoses should be plugged. Now, you can open the cylinder ports and let the hydraulic fluid drain.
Should hydraulic seals be replaced?
In addition, all polished surfaces should be inspected carefully, seals should always be replaced if they are removed, and specific torque values should be used when tightening important components. Lastly, if you incorrectly reassemble the hydraulic cylinder or fail to properly install seals, then this can result in more serious and costly damage.
Why repair hydraulic cylinders?
In most cases of failure, a specific component fails rather than the entire system, leaving other parts in excellent condition as long as the failure is caught relatively quickly. In such cases, only the damaged part needs to be replaced as is common with bearing and seal problems. Repairs may also be more economical than replacements, and, in the case of customized cylinders, may involve far less lead time.
What parts of a hydraulic cylinder fail?
There are quite a few parts in a hydraulic cylinder that can fail: the barrel (which contains most of the other parts), the piston rod (which is what most people see in motion), the piston (responsible for transferring motion to the piston rod), the cylinder head, the cylinder cap, and various seals and bearings.
What causes a piston rod to fail?
Failures can take many different forms. There can be contaminated fluid that accelerates wear, damages critical seals, and causes what seems like a sudden failure that had actually developed over time. Bearings, including eye bearings and piston rod bearings, can wear out and lead to catastrophic failure. Piston rods can be bent, leading to serious problems, and exposure to corrosive chemicals can damage steel and seals alike. Then there can also be dents in the barrel or rod that adversely affect performance and potential safety.

Why are hydraulic cylinders important?
Hydraulic cylinders are vital to keeping things moving, literally and figuratively. When issues arise and failures occur, there comes a time when you have to decide whether to repair the cylinder or have it replaced. There is a significant amount of information that needs to go into that decision, ranging from the cylinder’s expected life cycle to the lead time involved in a replacement. And then there are the cost issues involving not just the short-term economical benefits but what the cost of repairs or replacement is over the long-term. Key to such decisions is what caused the failure to occur in the first place: was the cylinder just worn out, or are there any underlying problems (e.g., alignment, hydraulic contamination) that need to be addressed before a solution is put into place?
What is the purpose of a cylinder before it is replaced?
Before a cylinder is replaced or repaired, it is important to address what caused or contributed to the failure so that the replacement does not fall prey to the same weakness. On the other hand, if a bearing or a seal simply wore out, a simple repair involving the replacement of those components should suffice.
How does efficiency affect hydraulics?
And that efficiency can affect other components in the hydraulic system, leading to energy losses and slightly higher costs related to power. A repair can solve these inefficiencies at a lower cost.
