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 a failing seal kit is typically visible hydraulic fluid leakage around the boom cylinder rod. If ignored, the leakage will worsen, leading to a gradual loss of hydraulic pressure and slower, less responsive boom operation. Continued operation risks significant hydraulic system contamination and potential damage to the cylinder rod.

Installation Tip

Carefully clean the cylinder bore and rod to prevent damage to the new seals during installation. Ensure all seals are properly oriented according to the kit's instructions to prevent immediate failure.

Service Note

Inspect the hydraulic fluid for contamination and check the cylinder rod surface for any scoring or pitting.
