9) Grasp the cutter and carefully lift out the extruding head.
10) Grasp the auger and carefully lift it out. When pulling out the auger, the upper part of the
mechanical seal should come out with it.
11) Remove the socket head cap screws securing the evaporator to the lower housing.
12) Raise the evaporator up to access the lower housing.
13) The mechanical seal consists of two parts. One moves along with the auger, and the
other is fixed on the lower housing. If the contact surfaces of these two parts are worn,
cracked or scratched, the mechanical seal may cause water leaks and should be
replaced.
14) Remove the mechanical seal from the housing. If only replacing the mechanical seal,
proceed to step 17. NOTICE! To help prevent water leaks, be careful not to damage
the surfaces of the O-ring or mechanical seal.
5b. Lower Housing
15) Remove the O-ring and the bolts securing the lower housing to the gear motor and
remove the 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 entire extruding head and housing.
16) Mount the lower housing onto the gear motor, then install the O-ring onto the lower
housing.
17) Install the lower part of the mechanical seal onto the lower housing.
18) Lower the evaporator down and secure it to the lower housing.
19) Install the auger assembly with the upper part of the mechanical seal attached. Replace
the cutter, extruding head, and evaporator flange in their correct positions. Align the
evaporator flange holes with the extruding head holes. See Fig. 7.
20) If new seal bolts do not have preapplied threadlocker, apply Loctite 243 or equivalent
threadlocker to seal bolts. Tighten new seal bolts to a torque of 11.1 ft-lb/15 N·m.
21) Tighten the cutter on the auger.
22) Replace the packing and spout in their correct positions.
23) Open the water supply line shut-off valve.
24) Plug the appliance into the electrical outlet, then move the control switch to the "ICE"
position to start the automatic icemaking process.
25) Once the appliance starts to produce ice, allow it to run for another 30 minutes. Check
for water leaks.
26) After 30 minutes, move the control switch to the "OFF" position. Unplug the appliance
from the electrical outlet.
27) Pour warm water into the storage bin and melt the ice. Clean the storage bin liner using
a neutral cleaner. Rinse thoroughly after cleaning.
