11) Remove the socket head cap screws securing the extruding head and evaporator ange.
Remove the evaporator ange, then grasp the cutter and carefully lift out the cutter and
extruding head. Grasp the top of the auger and carefully lift out the auger. When pulling
out the auger, the upper part of the mechanical seal should come out with it.
12) Remove the socket head cap screws securing the evaporator to the lower housing.
13) Raise the evaporator up to access the lower housing.
14) The mechanical seal consists of two parts. One moves along with the auger, and the
other is xed 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.
15) Remove the mechanical seal from the housing. If only replacing the mechanical seal,
proceed to step 18. NOTICE! To help prevent water leaks, be careful not to damage
the surfaces of the O-ring or mechanical seal.
5b. Lower Housing
16) 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 "V.C.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.
17) Mount the lower housing onto the gear motor, then install the O-ring onto the lower
housing.
18) Install the lower part of the mechanical seal onto the lower housing.
19) Lower the evaporator down and secure it to the lower housing.
20) Install the auger assembly with the upper part of the mechanical seal attached. Replace
the cutter, extruding head, and evaporator ange in their correct positions.
21) Open the water supply line shut-off valve and check for water leaks.
22) Plug the unit into the electrical outlet, then move the power switch to the "ON" position.
23) Allow the icemaker to operate until the gear motor starts. Check for water leaks.
24) Move the power switch to the "OFF" position, then unplug the unit from the electrical
outlet.
25) Replace the removed parts and panels in the reverse order of which they were removed.
26) Plug the unit into the electrical outlet, then move the power switch to the "ON" position
to start the automatic icemaking process.
