SECTION 8: SERVICE
WARNING: Disconnect the spark plug
wire and ground against the engine
before performing any repairs or
maintenance.
Engine
Refer to separate engine manual for all engine
maintenance procedures.
Augers
The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. See Figure 20. If you hit
a foreign object or ice jam, the snow thrower is
designed so that the bolts will shear.
If the augers will not turn, check to see if the bolts
have sheared. A replacement shear bolt and hex lock
nut have been provided with the snow thrower. When
replacing bolts, spray an oil lubricant into shaft before
inserting new bolts.
Shave plate and 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.
• To remove skid shoes, remove the four carriage
bolts, cupped washers and hex nuts which
attach them to the snow thrower. Reassemble
new skid shoes with the four carriage bolts,
cupped washers (cupped side goes against skid
shoes) and hex nuts.
• To remove shave plate, remove the carriage
bolts, cupped washers and hex nuts which
attach it to the snow thrower housing.
Reassemble new shave plate, making sure
heads of the carriage bolts are to the inside of
the housing. Tighten securely.
