Failure Symptoms

Initial signs of a failing piston assembly may include a gradual decrease in hydraulic system performance or increased cycle times. If left unaddressed, the issue can progress to noticeable power loss and erratic hydraulic operation. Continued operation with a compromised piston assembly risks damage to other hydraulic components due to increased stress and potential fluid contamination.

Installation Tip

Ensure the cylinder bore is thoroughly cleaned and free of any debris or scoring before installing the new piston assembly. Avoid forcing the piston into the cylinder, as this can damage the seals and the cylinder wall.

Service Note

Inspect the cylinder bore and hydraulic seals for wear or damage when replacing the piston assembly.
