To Remove the Water Seal:
(Assuming all steps to remove the auger have
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.
5. Carefully push the water seal (rubber side
against the auger shoulder and the silastic.)
/////////////////////////////CAUTION///////////////////////////
Do not get any silastic onto the face of the
seal.
/////////////////////////////////////////////////////////////////////////
6. Allow the auger and seal to air dry until the
silastic is dry on the surface.
7. If the original water seal was leaking, it
would be a good idea to inspect the interior of
the gearmotor.
To Replace the Evaporator:
(Assuming all the steps for removal of the
thrust bearing, breaker, auger, and water seal
have been performed.)
