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

A failing hydraulic cylinder seal kit will typically first present as external oil leaks around the cylinder rod or body. This can progress to jerky or slow cylinder operation as internal pressure is lost. If left unaddressed, significant hydraulic fluid loss can occur, leading to system malfunction and potential damage to other hydraulic components.

Installation Tip

Thoroughly clean the cylinder bore and rod before installing new seals to prevent damage from debris. Ensure all seals are properly seated and lubricated before reassembly.

Service Note

Inspect the cylinder rod for scoring and clean the hydraulic fluid for contamination when replacing cylinder seals.
