358-5009 Radial Piston Motor — Cat 250 226D

This radial piston motor is a high-torque, low-speed hydraulic motor designed to convert hydraulic energy into mechanical rotational force for applications like drive systems or winches. It is built with robust materials to meet demanding operational standards, offering superior longevity and efficiency over a worn motor that may exhibit reduced torque or increased leakage. Operators might observe a loss of drive power, unusual noises during operation, or excessive heat buildup in the hydraulic system when this motor is failing.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Early indicators of a failing radial piston motor include a noticeable reduction in torque, increased operating noise, or a slight hesitation during rotation. If ignored, the motor may experience progressively weaker performance, increased hydraulic fluid leakage, and potential overheating of the hydraulic system. The ultimate consequence of continued operation is the loss of power to the driven component, potentially immobilizing the equipment.

Installation Tip

Ensure all hydraulic lines are thoroughly flushed to remove any debris before connecting them to the new motor. Avoid rotating the motor shaft by hand during installation, as this can displace internal seals.

Service Note

Inspect the hydraulic pump and hydraulic fluid for signs of wear or contamination when replacing the radial piston motor.
