Failure Symptoms

Initial signs of a failing main pump seal kit include a gradual loss of hydraulic system pressure and slower response times for implement movements. If ignored, internal leaks will worsen, leading to reduced pump efficiency, potential overheating of the hydraulic oil, and external oil leaks from the pump housing. Continued operation risks significant damage to the pump's internal components.

Installation Tip

Carefully clean all internal pump surfaces and grooves before installing the new seals to prevent damage. Ensure all seals are seated correctly and not twisted during installation to guarantee a proper seal.

Service Note

When replacing the main pump seal kit, it is crucial to inspect the pump shaft for scoring or wear that could compromise the new seals.
