4.1.7. AUGER SHEAR BOLT REPLACEMENT
IMPORTANT: If engine is operating correctly and
auger/impeller drive belt is not damaged or severed,
but the auger/impeller does not rotate it is possibly
the auger shaft shear bolt.

old shear bolt and nut. DO NOT reuse bolt or nut
under any circumstances. Always replace existing
hardware with genuine Snapper new replacement
shear bolts and nuts. DO NOT substitute these
shear bolts and nuts with hardware other than what
is specified as auger/impeller and engine damage
can result.
2. Install new shear bolts and nuts. Tighten to 5 to
10 ft. lb. of torque. See Figure 4.11.
