Shear Pin Replacement; Belt Guide Adjustment - Snapper SMI I924E B&S 24 Operator's Manual

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 27. 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.)
