Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first observable sign of failing hydraulic cylinder seals is often external fluid leakage around the rod or piston. This can progress to slow or erratic cylinder operation, loss of lifting or holding capacity, and internal contamination of the hydraulic fluid. Continued operation risks damage to the cylinder, pump, or other hydraulic components.

Installation Tip

Carefully clean the cylinder bore and rod to remove any debris or old seal material that could damage the new seals. Ensure all new seals are properly lubricated with the recommended hydraulic fluid before installation.

Service Note

Inspect the hydraulic fluid for contamination and check the hydraulic pump and hoses for any signs of wear or leaks when replacing cylinder seals.
