Failure Symptoms

Initial signs of failure include a slight lag in boom extension or retraction speed. If ignored, the boom may exhibit noticeable drift when holding a position, and hydraulic fluid loss will become apparent. Continued operation with failed seals can lead to reduced hydraulic system efficiency and potential damage to other hydraulic components.

Installation Tip

Ensure the cylinder bore and rod are meticulously cleaned before installation to prevent debris from damaging the new seals. Avoid using sharp tools to install the seals, as this can easily cause nicks or tears.

Service Note

Inspect the hydraulic fluid for contamination and check the condition of the cylinder rod for any scoring or wear that might affect the new seals.
