Cutter And Bearing Removal/Installation.
Refer to FIGURES 9-3 & 9-4 for parts identification
and location.
1.
Turn off and lock out power to the machine.
2.
Remove the cutter motor from the reducer.
3.
Remove the water tank assembly and then the cutter assembly.
4.
With a 1/4” or slightly smaller punch reach in through the ice discharge opening, drive the spiral
pin out of the disc hub and cutter shaft, and push or drive the disc off the shaft.
5.
Lift the cutter assembly out of the bearing surface of the cutter. The surface should be smooth
and free from nicks or burrs.
6.
Inspect the bearing for wear. There should be no side movement between the shaft and bearing
and the bearing thrust flange should be no thinner than 3/16” (it is 1/4” thickness new).
7.
Before removing the bearing, reference mark the location of the bearing support on the side of
the tank.
8.
Loosen and remove the three cap screws from the bearing support ends and lift the support out of
the water tank.
9.
Drive the 3/16” x 1/2” pin located in the side of the support hub in and through the bearing wall.
10.
Now the bearing can be pressed or driven out of the support hub.
11.
Try the new bearing on the cutter shaft to make sure it turns easily.
12.
Press or drive the new bearing into the hub. Be careful not damage the bearing surfaces (the old
bearing may be used as a driver).
13.
Drill a 3/16” hole through the bearing wall, using the original hub hole as a pilot. Insert and
drive the 3/16” pin flush with the outside of the hub, making sure the pin doesn’t extend beyond
the inner surface of the bearing.
14.
Slide the new bearing and support onto the cutter shaft to make sure it spins freely. If it is tight,
ream the bearing inner surface slightly until it turns free.
15.
Install the bearing support in the tank, using the reference marks as a guide.
16.
Slide the cutter and shaft into the bearing and check the cutter alignment. By laying a straight
edge across the tank top flange, there should be 0” to 1/16” clearance between the rim of the
cutter and the top of the tank flange. Loosen the bearing support cap screws and drive the
support arms up or down for the proper alignment.
17.
Tighten the support screws securely and finish assembly of the cutter and cutter disc.
18.
Install the tank and other parts, reversing the procedure of removal.
