Failure Symptoms

A noticeable reduction in the speed and power of all hydraulic functions is a primary indicator of a failing hydraulic pump. If ignored, this can progress to intermittent or complete loss of hydraulic operation, rendering the machine unusable. The risk is significant downtime and potential damage to other hydraulic system components due to inadequate lubrication or pressure.

Installation Tip

Thoroughly flush the hydraulic system and replace all hydraulic filters before installing the new pump to prevent immediate contamination. Ensure the pump shaft is properly aligned with the drive coupling to avoid premature wear.

Service Note

When replacing the main hydraulic pump, it is essential to replace the hydraulic system filters and inspect the hydraulic fluid for any signs of contamination or degradation.
