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

Early indicators of a failing piston body might include minor hydraulic fluid leaks around the cylinder or a slight reduction in system performance. If the problem persists, expect a noticeable loss of power, increased noise from the hydraulic pump, or complete system failure. Continued operation with a compromised piston body can lead to severe internal damage and costly repairs to the hydraulic system.

Installation Tip

Thoroughly clean the cylinder bore and inspect for any scoring or damage before installing the new piston body. Ensure that all seals are properly lubricated and seated correctly to prevent immediate leaks.

Service Note

Inspect the cylinder liner, piston seals, and hydraulic fluid for contamination when replacing the piston body.
