SHEAR PIN REPLACEMENT

WARNING

Do not go near the discharge chute or auger

when the engine is running. Do not run the engine with any cover or guard removed.

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 30. 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.)
