10)Remove the bolts securing the housing to the gear motor and remove the housing from the gear motor. If inspection of the upper bearing inside the extruding head (see "F. 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 housing.

11)Mount the lower housing on the gear motor.

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

13 ) Lower the evaporator down and secure it to the lower housing.

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

2)Unplug the unit from the electrical outlet.

3)Remove the panels.

4)Remove the thumbscrews and take off the spout assembly from the evaporator.

5)Remove the bolts securing the lower housing to the gear motor. Lift the evaporator up slightly.
