Drive System
The drive system consists of all
components used to turn the auger.
The auger drive motor turns the gear
reducer via a V-Belt. A coupler is
used to connect the gear reducer to
the auger. The auger is located in
the evaporator and is supported by
two bearings, one at each end.
Auger Drive Motor and V-Belt
When facing the shaft, the auger
motor should turn
counter clockwise.
A pulley on the shaft of the motor
holds one end of the V-Belt, which is
used to connect the auger motor to
the input shaft of the gear reducer.
The pulley on the auger drive motor
must be aligned with the pulley on
the input shaft of the gear reducer.
This can be checked by placing a
straight edge across the face of the
two pulleys. If out of alignment, the
pulleys can be repositioned by
loosening the setscrew that holds the
pulley to the shaft, realign the pulleys
and then retighten the setscrew.
The V-Belt can be adjusted by
loosening the four (4) auger motor
mounting bolts and moving the motor
until the proper belt tension is
achieved. The belt should be
adjusted so that it will flex
approximately ½ inch when applying
slight pressure to the center of the belt. If the V-Belt is too tight, it will put an excessive load
on the auger motor and gear reducer. If the V-Belt is too loose, it may slip and reduce ice
production.

Auger motors should be oiled once a year with approximately 4 to 5 drops of SAE 20 oil in
each bearing.
Note: Models with two evaporators use a single drive motor with a shaft on each end of the
drive motor.
