Maintenance: Component Inspection

Auger. The auger is made of stainless steel. It has
a polished surface that may be very shinny or dull.
Allow the auger to dry, if mineral scale is found on
the auger's surface, clean off the auger with ice
machine cleaner and a scrubbing pad.
Remove the water seal and clean off the shoulder
of the auger.
Bearings: The top bearing should spin freely with
no rough spots. If it feels rough when spun by
hand, replace it. There should be minimal rust or
dirt. If in doubt, replace the bearing.
The bottom bearing must be removed from the
evaporator when replacing the water seal.
Remove the three bolts holding the evaporator to
the gearmotor adapter and lift the evaporator up
slightly. Tap the water seal and bottom bearing out
from the top down. Check the bottom bearing the
same way as the top.
Replace the water seal and install a new bearing
set if needed.
To replace the water seal:
1. Remove old rotating half from the auger. Clean
the mounting area.
2. Place a bead of food grade sealant (such as
Scotsman part number 19-0529-01) onto the
shoulder of the auger where the rotating half of the
water seal will be installed.
3. Wash the new seal in water. While wet, slip it
onto the bottom of the auger, rubber side toward
the auger. Push up until seated against the
sealant. Do not allow any sealant to come into
contact with the face of the seal.
4. Wash the stationary half the water seal with
water. Slip it up into the bottom of the evaporator
until the bottom of the seal is inside the evaporator
about 1/4".
5. Push the bottom bearing against the water seal
until the bottom bearing is inside the evaporator
about 1/16".
6. Replace the evaporator on the adapter, and
re-attach the stand using the original bolts.
7. Attach the auger to the top bearing and breaker.
8. Return the auger to the evaporator and slide it
down until the splines touch the coupling.
9. Rotate the auger until the coupling splines align
with the auger.
10. Push the auger down, and rotate the breaker
until the screw hole lines up with the pilot hole in
the evaporator.
11. When the auger is completely seated, reinstall
the breaker screws.
12. Replace spout and rubber top.
13. Switch on the water supply.
14. Observe operation. The unit should make
minimal noise while producing ice. Catch first 2
minutes of ice and discard it.
15. Replace all panels.
Coupling
Use the grease zerk on the side of the coupling to
add grease once per year.
That concludes normal maintenance. If the fan
motor has an oil plug, it may be oiled after 10
years of operation.
