Failure Symptoms

Initial signs of a failing piston motor include a gradual loss of speed or torque in the driven component, accompanied by increased hydraulic fluid temperature. If left unaddressed, the motor may seize or develop severe internal leaks, leading to a complete loss of function for the affected system. This can result in significant downtime and potential damage to the hydraulic pump.

Installation Tip

Always prime the new motor with clean hydraulic fluid before connecting the lines to ensure adequate lubrication upon startup. Avoid mixing different types of hydraulic fluid, as this can degrade seals and internal components.

Service Note

Inspect the hydraulic filter, reservoir, and associated hydraulic lines for any signs of wear or contamination.
