Failure Symptoms

Visible hydraulic fluid leaks around the arm cylinder are the first sign of seal failure. If ignored, the leaks will worsen, leading to a gradual loss of hydraulic power and slower arm movements. Eventually, the cylinder may lose its ability to hold its position, impacting the machine's digging efficiency and stability.

Installation Tip

Clean the cylinder bore and rod thoroughly before installation to prevent debris from damaging the new seals. Ensure seals are correctly oriented and seated before reassembling the cylinder.

Service Note

Inspect the cylinder rod for any scoring or pitting that could damage the new seals.
