Watch the video that was posted above. about 1:40 into it Don goes over the 3 pins that can break. The two closest to the boiler are cotter pins, and normally should not need to be changed. The pin at the end of the shaft (next to the main drive gear) is the shear pin, and that is typically what breaks if there is an obstruction in the auger.
