Bearing Replacement:
Top Bearing Replacement
If the inner race is secure, use an arbor press to
push the top bearing out of the breaker. If the inner
race has separated from the bearing, replace the
breaker.
Insert a new bearing in the breaker, check for
orientation:
The top of the bearing has a wider inner race and
a narrower outer race than the bottom.
Replace the "O" ring in the breaker.
Push the bearing in, push only on the outer race.
Water Seal & Bottom Bearing Replacement:
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 holes line up with
the pilot holes in the evaporator.
11. When the auger is completely seated,
reinstall the breaker screws.
12. Replace permagum and foam top.
13. Switch on the water supply.
14. Check bin cover for electrical grounds
and switch on the electrical power.
15. Observe operation. The unit should
make minimal noise while producing ice.
Catch first 2 minutes of ice and discard it.
16. Replace the bin cover and all panels.
