How do you remove a piston hydraulic cylinder?
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.
How do you remove a stuck hydraulic cylinder pin?
If you don’t want to use td25c’s method (which is a good one), put a long hacksaw blade in a reciprocating saw and cut through the pin on both sides of the rod eye. Then you can put the rod in a press. The pin may not be seized in the rod.
Can a hydraulic cylinder get stuck?
The cylinder becomes hydraulically locked when the rod seal leaks due to pressure around the piston equalizing. Excessive heat can also create hydraulic drift.
What is the gland on a hydraulic cylinder?
The cylinder head is fitted with seals to prevent the pressurized oil from leaking past the interface between the rod and the head. This area is called the seal gland. The advantage of a seal gland is easy removal and seal replacement.

What would cause a hydraulic cylinder to not retract?
If the rod does not retract, it could be an indication of internal leakage or port blockage. As such, you will have to check all ports and pipes for blockage. In addition, you need to check valve operation. Dampness on the piston rod is a sign of possible leakages, mainly caused by worn seal of the cylinder rod gland.
