Failure Symptoms

Initial symptoms of a failing pump may include a slight reduction in hydraulic system speed or responsiveness. If left unaddressed, the problem can escalate to significant power loss, inability to operate implements, and potential overheating of the hydraulic fluid. A severely degraded pump can lead to complete hydraulic system failure, halting machine operation.

Installation Tip

Ensure the hydraulic system is completely flushed and clean before installing the new pump to prevent contamination. Never run the new pump dry; prime it according to the service manual instructions before initial startup.

Service Note

Always replace hydraulic filters and inspect the hydraulic fluid for debris or metal particles when replacing the pump group.
