COMMERCIAL HYDRAULIC MOTOR
INSTALLATION INSTRUCTIONS
1. Use the motor selection chart to select the proper hydraulic motor to correspond
with the GPM flow rating of the loader to be used.
2. Install O-ring (PN / N11859) in groove at rear of the bearing block (PN / N10533).
It may be helpful to use grease to hold the O-ring in position.
3. Start the motor output shaft into the splined coupler of the bearing block and
carefully slide the motor forward till the motor mounting flange mates with the
mounting surface of the bearing block. Be sure the O-ring stayed in position and
didn’t get damaged.
(Note: The body of the motor is offset from the output shaft. Install with the belly
side of the motor hanging down.)
4. Install 2 / 1-1/4” x ½” UNC Gr. 8 bolts in the lower 2 holes of the motor mount.
(Note: It may be necessary to grind a corner off the head of the 1-1/4” bolts to
allow clearance for installation into the lower 2 holes of the motor mounting flange.)
5. Install 4 / 1-1/2”x ½” UNC Gr.8 bolts in the remaining 4 mounting holes.
Use a thread locking compound to assure that all 6 bolts will stay securely fastened.
6. Using a staggered pattern, tighten all 6 bolts to 50 ft.lbs. of torque, then to 75 ft.lbs.,
and finally to the maximum torque setting of 100 ft.lbs.
7. Replace hydraulic fittings and hoses as shown in the operator’s manual.
8. Follow the Dealer Pre-Delivery Set-up Instruction sheet to prepare the cutter for
operation.
9. After carefully checking for hydraulic leaks, the cutter should be ready to go.
(Note: Because there is no shaft seal used with this motor setup, it is extremely
important to protect the internal parts of the spare motors from foreign materials
by enclosing the complete motor in a plastic bag or other sealed container.)
