Cutter Motor Removal/Replacement. The cutter motor’s bearings are prelubricated and sealed
and require no further lubrication. If the motor needs replacing, proceed as follows:
1.
Turn power off and lock out disconnect.
2. Check terminals with volt meter to confirm 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 which must be reinstalled later.
5. Check the motor electrically to confirm it is defective.
6. Apply Anti-Seize lubricant to the shaft of the replacement motor.
7. Position the shaft key in the motor key-way, align it with the reducer key-way and install the
motor. Make sure the key stays in.
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 make sure the cutter turns in the proper direction. Reverse two wires at
the motor if necessary to change rotation direction.
Cutter Gear Reducer Removal/Replacement. To remove the gear reducer, proceed as follows:
Turn power off and lock-out disconnect.
1.
Remove motor from reducer.
2. Loosen (slightly) the four bolts and nuts holding the gear reducer in place.
Remove the four bolts holding the mounting plate to the water tank gear enclosure and remove
the reducer and mounting plate from the tank.
3. Measure the distance between the top of drive gear and the mounting plate for future reference.
4. Remove the three cap screws from the gear and hub and install two 1/4”-20 x 2” long all thread
set or 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 tapered split hub.
5. In necessary, the split hub can be removed by driving a screw driver in the split and sliding the
hub off the shaft.
6. The new gear reducer can then be installed by reversing the removal procedure.
7. Be sure the gear and hub is properly positioned on the shaft so it will have a full vertical mesh
with the cutter ring gear.
8. Final gear meshing should be adjusted so there is only a slight amount of play between the ring
gear and drive.
9. Make sure all bolts are tightened securely and there is no excessive gear noise when the cutter
motor is running.
Water Tank Removal.
1. Turn off and lock out power to the machine.
2. Turn off water supply and disconnect lines from the tank.
3. Drain the tank and disconnect pump suction tube and drain line tubing and water lines.
4. Disconnect the ice discharge chute.
5. Loosen bolts holding the tank to the cutter assembly until the tank rests on the casters.
6. Remove cutter motor and gear reducer together. Hang on machine frame to support and secure.
7. Loosen bolts holding the tank supports.
8. The tank can then be removed to the side of the machine.
Make sure the rubber gasket is in place and aligned properly when the tank is reinstalled and
bolted to the freezer.
