TO REPLACE AUGER SHEAR BOLT

..... ........ ..........

....

The augers are secured to the auger shaft with special shear bolts (See Fig,. 34) that are designed to break (to protect the machine) if an object becomes lodged in the auger housing. Use of a harder bolt will destroy the pro- tection provided by the shear bolt.

IMPORTANT: TO INSURE SAFETY AND PERFORMANCE LEVELS, ONLY ORIGINAL EQUIPMENT SHEAR BOLTS SHOULD BE USED. WHEN REPLACING SHEAR BOLTS, BE SURE TO REPLACE SHEAR BOLT SPACERS

To replace a broken shear bolt, proceed as follows:

oMove the throttle to STOP and turn off all controls.

oDisconnect the spark plug wire. Be sure all moving parts have stopped.

oLubricate the auger shaft by squirting oil into the shear bolt hole in the auger shaft. Then rotate the auger to distribute the oil on the shaft

eAlign the hole in the auger with the hole in the auger shaft. Install the new shear bolt and Iocknut
