Shave Plate & Skid Shoes
The shave plate and skid shoes on the bottom of the
snow thrower are subject to wear. They should be
checked periodically and replaced when necessary.
1. Remove the four carriage bolts, belleville washers
and hex nuts which attach skid shoes to the snow
thrower on two sides. See Figure 11.
2. Reassemble new skid shoes with the four carriage
bolts, bellevilte washers (concave side goes
against skid shoes) and hex nuts. Make certain the
skid shoes are adjusted to be level.
3. To remove shave plate, remove skid shoe and rest
of the hardware including carriage bolts, belleville
washers and hex nuts which attach shave plate to
the snow thrower housing. For location of shave
plate, see Figure 11.
4. Reassemble new shave plate, making sure heads
of the carriage bolts are to the inside of the housing.

Augers
The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. See Figure 11 . If you
hit a foreign object or ice jam, the snow thrower is
designed so that the bolts will shear.
If the augers do not turn, check to see if the bolts have
sheared. Replace if necessary. See Figure 11.
Two replacement shear bolts and hex lock nuts have
been provided with the snow thrower. This type of nut is
used where vibration occurs. Since lock nuts cannot be
threaded onto a bolt by hand, use a wrench. When
replacing bolts, spray an oil lubricant into shaft before
inserting new bolts.
Replacing Belts
NOTE: There are two belts on this snow thrower: auger
belt and drive belt. It is recommended that both belts be
replaced at the same time.
1. Remove the spark plug wire from the spark plug
and ground it against the engine.
2. Drain gasoline from the gas tank, or place a piece
of plastic sheet underneath the gas cap to prevent
gasoline leakage.
3. Remove the self-tapping screw shown in Figure 11,
and push the belt cover to release the plastic tabs.
Pull the belt cover out from around the engine and
the chute. Remove it away and save.
