Cutter Motor Replacement
The cutter motor bearings are pre-lubricated and sealed, requiring no further lubrication or maintenance. If the
motor requires replacement, follow the steps below:
1. Turn the power off and lock out the disconnect.
2. Check terminals with voltmeter to confirm the power is off.
3. Remove motor terminal cover and disconnect wires. Mark wires for ease of replacement.
4. Remove four cap screws around the motor flange and separate the motor from the reducer. Watch for
shaft key that must be reinstalled later. Replacement motor does not come with a new key.
5. Check the motor electrically for shorts to confirm that it is defective.
6. Apply anti-seize lubricant to the shaft of the replacement motor.
7. Position the shaft key in the motor keyway, align it with the reducer keyway, and install the motor.
Make sure that the key stays in position as the shaft is inserted.
8. Install the four cap screws to hold the motor in place on the reducer.
9. Connect the wires and install the terminal cover.
10. Check motor rotation to verify that the cutter turns counterclockwise. Reverse two wires at the motor if
necessary, to change rotation direction.
Cutter Gear Reducer Removal and Replacement
To remove the gear reducer, follow the steps below (refer to Figure 41):
1. Turn the power off and lock out the disconnect.
2. Remove the motor from the gear reducer.
3. Slightly loosen the 4 bolts and nuts holding the gear reducer in place.
4. Remove the four bolts holding the mounting plate to the water tank gear enclosure and remove the
gear reducer and mounting plate from the tank.
5. Measure the distance between the top of the drive gear and the mounting plate for future reference.
6. Remove the three cap screws from the gear and hub and install 2-1/4-in. [57 mm] -20 x 2-in. [51 mm]
long cap screws in the threaded holes of the drive gear. These two screws can be used as jacking bolts to
remove the gear from the taper split hub.
7. The split hub is removed by placing a screwdriver in the split and sliding the hub off the shaft.
8. The new gear reducer is installed by reversing the removal procedure.
9. Check that the gear and hub are properly positioned on the shaft. The driver and cutter ring gears must
mesh completely along the gear thickness as installed in the machine.
10. Adjust the final gear mesh so that only a slight amount of play exists between the drive gear and the ring
gear.
11. Check that all bolts are tightened securely and that there is no excessive gear noise when the cutter
motor is running.
