Drive System

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-BeltWhen 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 Coupler pulleys can be repositioned by

loosening the setscrew that holds the pulley to the shaft, realign the pulleys and then retighten the setscrew.

Evaporator

Drip Boot

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.
