REMOVAL AND REPLACEMENT
Ice Breaker and Auger Removal
1. Remove styrofoam cap and two screws from the
side of the evaporator.
2. Pull up on cap hook located in the top of the
freezer assembly to remove the ice breaker
assembly, auger, and the top portion of the water
seal.
3. Remove the snap ring and cap, and remove the
bolt from the ice breaker and auger assembly to
separate the ice breaker assembly from the auger.
The bearings may be replace or the ice breaker
and bearings may be replaced as an assembly.
3. Apply Scotsman part number 19-0529-01 food
grade sealant to the auger shoulder before
pushing on the water seal. Place just enough
sealant onto the shoulder of the auger, so that
when the water seal is placed on the auger, the
gap between the auger shoulder and the water
seal is completely filled with the sealant.
4. Clean the inside of the evaporator at the bottom
bearing and water seal mounting area. Lubricate
the outside edge of the stationary seal with water.
5. Carefully push the stationary part of the water
seal up into the bottom of the evaporator. It must
go in straight and must not be pushed in beyond
1/4" past the bottom of the evaporator.
6. Install a new bottom bearing, push it into the
evaporator under the new
water seal. It must be pushed
in straight, but do not push it in
past 1/8" from the bottom of
the evaporator tube.
7. Mount the adapter stand to
the bottom of the evaporator.
Hand tighten the three cap
screws until the stand flange is
tight against the bottom of the
evaporator. Hand tighten the
three cap screws until the
stand flange is tight against
the bottom bearing. Then,
tighten the screws in a rotating
pattern to insure proper
alignment.
8. The
top bearing should also be
changed at this time. Be sure
to mount the top
breaker/bearing assembly onto the
auger before installing the auger into the
evaporator tube.
9. Lower the auger into the evaporator,
twist it to engage the splines of the
coupling. Secure the breaker and
bearing to the evaporator tube with the
two screws removed in step 1 of “Ice
Breaker and Auger Removal”. Test the
unit.
