Failure Symptoms

Initial signs of failure include visible hydraulic fluid seepage around the adjust cylinder rod. If left unaddressed, this can lead to a gradual loss of hydraulic pressure, resulting in inconsistent or slack track tension. Continued operation with leaking seals can compromise the undercarriage's stability and potentially lead to uneven wear on components.

Installation Tip

Clean the cylinder bore and piston rod thoroughly before installation to remove any debris that could damage the new seals. Ensure the seals are properly oriented and seated without twisting to maintain their sealing integrity.

Service Note

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