Failure Symptoms

The first indication of a failing gear assembly might be a whining or grinding noise from the hydraulic pump. As wear progresses, hydraulic power will noticeably decrease, and functions may become sluggish. Continued use risks significant damage to the hydraulic pump housing and other internal components.

Installation Tip

Ensure all mating surfaces are clean and free of debris before assembly to achieve a proper seal. Avoid forcing the gear assembly into place; it should fit smoothly if aligned correctly.

Service Note

Inspect the hydraulic pump housing, seals, and hydraulic fluid for any signs of wear or contamination when replacing this gear assembly.
