AUGER SHEAR BOLT REPLACEMENT
The augers are secured to the auger shaft with special bolts
that are designed to break if an object becomes lodged in the
auger housing. Use of a harder bolt will reduce the protection
provided by the shear bolt. To replace a broken shear bolt,
proceed as follows:
NOTE: For the operator's convience, the shear bolt
wrenches are located in the toolbox.
NOTE: The spacer fits into the larger hole in the auger
tube.
WARNING: To insure safety and performance
levels, only original replacement shear bolts
should be used.
1. Move throttle to STOP, disengage all controls, discon-
nect the spark plug lead wire, and insure all moving parts
have stopped.
2. Lubricate the auger shaft zerk fittings (see Lubrication
Points in the Maintenance section of this manual).
3. Align the hole in the auger with the hole in the auger shaft.
Install new shear bolt, spacer and Iocknut found in the
