BELT HEATER
8) Detach the spring, and remove the belt heater.
EXTRUDING HEAD
9) Remove the sealing bolts, and lift off the extruding head.
10) Check the bearing inside the extruding head. If it is worn out or scratched, replace the
bearing.
Note: Replacing the bearing needs a fitting tool. If it is not available, replace the whole
extruding head.
AUGER
11) Lift out the auger. Check the top and bottom areas in contact with the bearings. If the
surface is scratched or pitted, replace the auger. Check the blade edge of the auger. If it
is scratched or worn where it has contacted the evaporator, replace it.
EVAPORATOR
If the evaporator requires removal or replacement, please contact the manufacturer.
HOUSING AND MECHANICAL SEAL
12) The mechanical seal consists of two parts. One part rotates with the auger, the other is
static and is fitted into a top recess in the housing. If the contact surfaces of these two
parts become worn or scratched, the mechanical seal may leak water and should be
replaced.
13) Remove the O-ring on the top outer edge of the housing.
14) Remove the four bolts and lift the housing clear of the gear motor. Check the bearing
inside the housing. If it is worn or scratched, replace it using a fitting tool. Carefully ease
out the lower part of the mechanical seal before replacing the bearing.
Note: If a fitting tool is not available, replace the whole lower housing complete with
bearing.
GEAR MOTOR
15) Cut the connectors.
16) Remove the three socket head cap screws securing the gear motor.
17) Assemble the removed parts in the reverse order of which they were removed.
