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

Observable signs of failure include sluggish or erratic boom movement, or visible hydraulic fluid leaks from the cylinder seals. If ignored, the boom may lose its ability to hold position under load, leading to reduced operational capability. The worst-case consequence is uncontrolled boom movement, posing a significant safety risk.

Installation Tip

Before installation, thoroughly flush the hydraulic system to remove any contaminants that could damage the new cylinder's seals. Ensure the cylinder rod is clean and properly lubricated before inserting it into the barrel.

Service Note

Inspect hydraulic hoses, fittings, and the hydraulic fluid level and condition when replacing the boom cylinder.
