Failure Symptoms

Early indicators of a failing main hydraulic pump include a noticeable loss of power during operation and slower response from the boom, stick, and bucket. If the issue persists, the pump will struggle to maintain system pressure, leading to erratic movements and potential overheating. Ignoring these symptoms can result in damage to other hydraulic components and extended downtime.

Installation Tip

Thoroughly clean the hydraulic system and reservoir before installation to prevent any residual contaminants from damaging the new pump. Ensure the pump shaft is properly aligned with the drive coupling to avoid premature wear on the shaft or coupling.

Service Note

Inspect the hydraulic system for leaks, clean the hydraulic oil cooler, and replace the hydraulic filter element.
