SHEAR PIN REPLACEMENT

WARNING

 

 

B

 

 

 

Do not go near the discharge chute or auger

 

 

when the engine is running. Do not run the

A

 

engine with any cover or guard removed.

 

Under most circumstances, if the auger strikes an

 

 

object which could cause damage to the unit, the

 

A

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 28. To replace the shear pins, tap out

 

 

the broken pin with a pin punch, and install a new

 

 

shear pin and cotter pin. Do NOT replace shear pins

 

 

with anything other than the correct grade

 

 

replacement shear pin. (Use of bolts, screws or a

 

 

harder shear pin will lead to damaged equipment.)
