12)Remove the O-ring and mechanical seal from the housing. If only replacing the mechanical seal, proceed to step 15.

WARNING

To help prevent water leaks, be careful not to damage the surfaces of the O‑ring or mechanical seal.

6b. Lower Housing

13)Remove the hex bolts w/washers securing the lower housing to the gear motor and remove the lower housing from the gear motor. If inspection of the upper bearing inside the extruding head (see "V.B.1. Upper Bearing Wear Check") indicates that it is out of tolerance, replace both it and the bearing inside the lower housing.

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

14)Mount the lower housing on the gear motor.

15)Install the O-ring and lower part of the mechanical seal on the lower housing.

16 ) Make sure the lower mechanical seal is in place, then place the evaporator in position. Secure the evaporator to the lower housing using the socket head cap screws and split lock washers.

17)Install the auger assembly with the upper part of the mechanical seal attached.

18)Replace the removed parts in the reverse order of which they were removed.

19)Replace the top and side panels in their correct positions.

20)Move the control switch to the "ICE" position.

21)Plug the unit into the electrical outlet, then move the power switch to the "ON" position to start the automatic icemaking process.

22)Replace the front panel in its correct position.

7.Removal and Replacement of Gear Motor

1)Remove the front panel, then move the power switch to the "OFF" position.

2)Move the control switch to the "DRAIN" position.

3)Move the power switch to the "ON" position.

4)Allow the water to drain from the evaporator.

5)Move the power switch to the "OFF" position, then unplug the unit from the electrical outlet.

6)Remove the top and side panels.

7)Remove the strap connecting the spout to the chute assembly, then remove the spout.

8)Remove the hex head bolts and washers securing the lower housing to the gear motor. Lift the evaporator up slightly.

9)Remove the socket head cap screws with split lock washers securing the gear motor.

10)Disconnect the gear motor wiring, then remove the gear motor.
