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 sign of failure is often a gradual loss of hydraulic system performance or visible fluid seepage. If ignored, the leakage will worsen, leading to reduced lifting capacity and slower cycle times. Unaddressed, this can result in insufficient hydraulic pressure to operate critical functions, potentially halting equipment operation.

Installation Tip

Ensure the cylinder bore and rod are meticulously clean before starting to prevent damage to the new seals. Avoid using sharp tools that could nick or scratch the delicate sealing surfaces during installation.

Service Note

Inspect the hydraulic cylinder rod for any scoring or damage that could compromise the new seals' effectiveness.
