Gear Reducer
The gear reducer transfers torque to the auger. The auger drive motor turns the input shaft of the gear reducer at a high rate of speed. The input shaft turns a worm (screw type gear) that meshes with a worm gear (bronze gear). The worm gear turns the output shaft at a reduced speed.
The gear reducer should be inspected for oil leakage, noise, and vibration during scheduled maintenance of the machine. If the gear reducer is noisy, vibrating or seizing, the oil level may be low, internal parts may be worn, or the gear reducer may be under excessive load due to a problem in the evaporator. If a problem is found with the gear reducer, it must be replaced.
If the gear reducer is damaged, it may bind or lock up causing the auger motor to shut off on overload. This is usually caused by a damaged worm gear due to lack of lubricant or
excessive loading of the gear reducer.

Coupler
The coupler is a three piece assembly used to connect the gear reducer to the auger. The coupler includes the upper half, lower half and the nylon “spider” which fits between the teeth of the coupling halves, preventing metal to metal contact of the coupling teeth.
There should be an 1/8 inch gap between the coupler halves. The “spider should fit tightly between the coupling teeth. If there is excessive play between the coupling halves, the “spider” should be inspected for wear and replaced.
