Failure Symptoms

Early signs of pump failure may include unusual noises like whining or groaning from the hydraulic system and a gradual reduction in hydraulic power. If not addressed, these symptoms will progress to slow or erratic operation of hydraulic functions. Continued operation risks overheating the hydraulic fluid and potentially damaging other system components.

Installation Tip

Ensure the hydraulic reservoir is completely full with the correct fluid type after installation to prevent air from being drawn into the system. Never attempt to rotate the pump shaft by hand before it is securely mounted and connected.

Service Note

It is essential to replace the hydraulic filter and inspect the hydraulic fluid for any signs of debris or wear when installing a new pump group.
