REMOVAL AND REPLACEMENT: Water Seal
To Remove the Water Seal:
(Assuming all steps to remove the auger have
REMOVAL OF THE WATER SEAL
been performed.)
1. The gearmotor/evaporator assembly will have to
be pulled away from the machine (if not yet done).
2. Remove the 4 hex head cap screws holding the
evaporator to the gearmotor assembly. Lift the
evaporator up and off of the gearmotor.
3. Remove the snap ring or wire retainer from the
grove under the water seal.
4. Pull or drive out the lower half of the water seal.
To Replace the Water Seal:
1. Lubricate the water seal with water, and push
the water seal into the bottom of the evaporator
slightly past the grove for the snap ring.
2. Replace the snap ring and pull the water seal
down against it.
3. The part of the water seal that rotates with the
auger must also be replaced. Remove the old part
from the auger and clean the mounting area.
4. Place a small bead of food grade silastic sealant
(such as 732 RTV or Scotsman part number
19-0529-01) on the area of the auger where the
water seal is to be mounted.

a good idea to inspect the interior of the gearmotor.
