SHEAR PIN REPLACEMENT
Under most circumstances, if the auger strikes an object
which could cause damage to the unit, the shear pin will
break. (This protects the gear box and other parts from
damage.)
The shear pins are located on the auger shaft as shown
in Figure 31. To replace the shear pins, tap out broken
pin with a pin punch, and install a new shear pin and cot-
ter pin. Spread the legs of the new cotter pin fully. Do
NOT replace shear pins with anything other than the
correct grade replacement shear pin. See the
REPLACEMENT PARTS section at the back of this man-
ual for the correct part numbers. (Use of bolts, screws or
a harder shear pin will lead to damaged equipment.)
