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:
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 locknut found in the
toolbox located on the belt cover (See Figure 55).
NOTE: The spacer fits into the larger hole in the auger
tube.

TO ADJUST OR REPLACE THE SPARK PLUG
Check the spark plug every twentyfive (25) hours. Re-
place the spark plug if the electrodes are pitted or burned
or if the porcelain is cracked.
1. Clean spark plug and reset gap periodically.
2. Clean area around spark plug base before removal, to
prevent dirt from entering engine.
3. Replace spark plug if electrodes are pitted or burned or
if porcelain is cracked.
4. Clean spark plug by carefully scraping electrodes (do not
sandblast or use wire brush).
5. Be sure spark plug is clean and free of foreign material.
Check electrodes gap with a wire feeler gauge and reset
gap to 0.030” (0.76 mm) if necessary. If a new spark plug
is needed, refer to Engine Repair Parts section of this
manual for proper replacement spark plug.
6. Before installing spark plug, coat threads lightly with
graphite grease to insure easy removal.
7. Tighten plug firmly into engine. If torque wrench is avail-
able, torque plug to 1823 ftlbs.
