6b. Lower Housing
9) 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 "IV.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.
10) Mount the lower housing on the gear motor.
11) Install the O-ring and lower part of the mechanical seal on the lower housing.
12) 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.
13) Install the auger assembly with the upper part of the mechanical seal attached.
14) Replace the removed parts in the reverse order of which they were removed.
Note: Be sure to use new seal bolts. See "Seal Bolt Removal and Installation
Instructions" earlier in this section.

2) Remove the top and side panels.
3) Remove the strap connecting the spout to the chute assembly, then remove the spout.
4) Remove the hex head bolts and washers securing the lower housing to the gear motor.
Lift the evaporator up slightly.
5) Remove the socket head cap screws and split lock washers securing the gear motor.
6) Disconnect the gear motor wiring, then remove the gear motor.
7) Remove the gear motor bracket and spline coupling from the old gear motor and place
