1. Upper Bearing Wear Check

To ensure that the bearing inside the extruding head does not exceed the wear tolerance of .02", follow the instructions below. See Fig. 2.

1) Move the control switch to the "OFF" position, then turn off the power supply. Remove

the front and top panels, then move the power switch to the "OFF" position.

2) Remove the front cover of the storage bin. Remove spout B,

.02" Round Stock

then remove spout A and the cutter. See Fig. 1.

3) Grasp the top of the auger and move

or Pin Gauge

Auger

the auger towards you and then try to

Extruding

insert a .02" round stock or pin gauge in

Head

between the back side of the auger shaft

 

and the bearing surface. Check several

 

locations around the auger shaft. If the

 

gauge goes between the shaft and the

 

bearing at any point or if the bearing is

 

scratched or cracked, both the top bearing

 

in the extruding head and the lower

 

bearing in the housing should be replaced.

Instructions for removing the extruding

head and housing are located later in this

 

procedure.

 

Note: Replacing the bearing requires a bearing press adaptor. If one is not available, replace the whole extruding head and housing.

4)Replace the cutter, spout A, spout B, and the front cover of the storage bin in their correct positions.

5)Move the power switch to the "ON" position, then replace the panels in their correct positions.

6)Turn on the power supply, then move the control switch to the "ICE" position to start the automatic icemaking process.

2.Removal and Replacement of Extruding Head

1)Move the control switch to the "DRAIN" position and drain all of the water from the evaporator.

2)After the water has stopped draining, move the control switch to the "OFF" position, then turn off the power supply. Remove the front and top panels, then move the power switch to the "OFF" position.

3)Remove the front cover of the storage bin. Remove spout B, then remove spout A and the cutter. See Fig. 1.

4)Remove the apron panel, then remove the left side panel.

5)Remove the extruding head heater, then remove the allen head cap screws and lift off the extruding head.

6)Place the new extruding head in place and tighten down the allen head cap screws.

7)Replace the extruding head heater and cutter in their correct positions.
