Failure Symptoms

Visible hydraulic fluid leaks around the main pump housing are the first sign of seal failure. If ignored, these leaks will worsen, leading to a gradual loss of hydraulic system pressure and performance. Eventually, the pump may suffer internal damage due to insufficient lubrication or pressure loss, requiring more extensive repairs.

Installation Tip

Thoroughly clean the pump housing and all mating surfaces before beginning assembly to prevent debris from compromising the new seals. Ensure seals are installed with the correct orientation to prevent immediate leakage.

Service Note

Inspect the hydraulic pump shaft for scoring or wear, and check the hydraulic fluid for contamination.
