REPLACING HYDRAULIC MOTOR

 

When replacing the hydraulic motor the unit should be setting on the ground 

with the hydraulic couplers disconnected.

NOTE: Field replacement of the internal motor seals voids warranty.

1. 

With unit setting on the ground and hydraulic couplers disconnected, tag and 

disconnect the hydraulic hoses and fittings from the hydraulic motor. Note 

the hose routing for re-installation.

2. 

Loosen the four sockethead capscrews on the coupler and slide the motor 

out of the coupler.

3. 

Remove the capscrews holding the motor to the motor mounting plate(s), 

and remove the motor.

4. 

Install the new motor onto the mounting plate(s) using the existing hardware.

5. 

Slide the motor with the mounting plate(s) into the coupler and retighten the 

sockethead capscrews. Torque all hardware to specification. See Section O.

6. 

Re-connect the hydraulic hoses and fittings to the new motor. 

WARNING!  Avoid serious injury. Lower the rotary cutter to the ground, 

set the parking brake, stop the skid-steer engine, and remove 

the key before leaving the operator's seat.  If unit must be left 

raised for maintenance, block the unit securely to prevent 

accidental release of the lifting mechanism. Disconnect the 

hydraulic couplers.
