Failure Symptoms

Initial signs of a failing main hydraulic pump include sluggish or weak hydraulic functions and a noticeable increase in hydraulic system temperature. If ignored, the pump's output will continue to decrease, leading to reduced productivity and potential overheating. Continued operation with a compromised pump risks damage to other critical hydraulic components.

Installation Tip

Ensure the hydraulic system is completely drained and flushed to remove any debris before installing the new pump. Avoid overtightening the mounting bolts, as this can distort the pump housing and lead to premature failure.

Service Note

Inspect and replace hydraulic filters, and check the condition of hydraulic hoses and fittings when replacing the main hydraulic pump.
