Check the motor is hooked up correctly and has pressure and flow.
About Hydraulic Motors
- Purpose of a Hydraulic Motor: Convert hydraulic power into a rotary (rotational) mechanical motion.
- How it works: Fluid enters the motor, pushes rotors, which are connected to a shaft. The shaft can then be attached to a load.
- When it is used: When rotational work needs to be done.
Common Component Failure Problems
- Check that the hoses are hooked up correctly.
- If motor is unidirectional, hoses should be hooked up in correct direction.
- If motor is bidirectional, hoses should be hooked up in the direction intended.
- Check pressure and flow.
- Is motor getting expected pressure?
- If not, problem is likely upstream.
- Is motor getting expected flow? Is the flow high enough for the valve to function properly?
- If not, problem is likely upstream.
- Internal components damaged.
- If hooked up correctly and getting expected pressure and flow, internal components are likely broken or worn out.
- Rebuild or replace motor.
