Failure Symptoms

Early signs of a failing cylinder include a gradual decrease in the speed or force of the operated component, or audible signs of internal leakage. If ignored, the cylinder may lose its ability to hold position or extend fully, impacting operational capability. Continued use risks further internal damage and potential contamination of the hydraulic system.

Installation Tip

Ensure the cylinder rod and mounting points are clean and free from damage before installation to prevent compromising the new seals. Always bleed air from the hydraulic system after installation to ensure proper operation.

Service Note

Inspect the hydraulic fluid for signs of contamination and check the condition of the associated hydraulic lines and fittings.
