REMOVAL OF BLOWER HOUSING AND BELT
REPLACEMENT
CAUTiON: SINCE REPLACING THE BELTS WILL IN
VOLVE TURNING THE ENGINE OVER WITH THE
STARTER, AND THE ENGINE MIGHT ACCIDENTALLY
START RESULTING IN INJURY, THE SPARK PLUG
WIRE MUST BE DISCONNECTED DURING THIS PRO
CEDURE.
The traction drive belt and the blower drive belt are
both accessible by removing the blower housing as
follows:
1. See Figure 21 ("ASSEMBLY & PRE-SERVICE"
section). Remove hairpin securing the deflector
control cable to the deflector. Loosen jam nuts
securing deflector control cable to bracket on
chute. Then free the cable from the Sno-Thro
blower housing.
2. Remove the hair pin cotter in the chute crank
assembly. Separate the chute crank. See Figure 4.
3. Remove the two screws securing the belt guard to
the tractor. Remove the belt guard.
NOTE: TIPPING THE TRACTOR BACK ON THE
HANDLEBARS WHEN SEPARATING THE UNITS MAY
RESULT IN BENDING THE BOTTOM COVER. TO
AVOID THIS SITUATION, EITHER TIP THE UNIT UP ON
THE BLOWER HOUSING AND REMOVE THE BOTTOM
COVER BEFORE SEPARATING THE UNITS; OR SUP
PORT THE HANDLEBARS SO THE TRACTOR DOES
NOT TIP ALL THE WAY OVER; THEN LIFT OFF THE
BLOWER HOUSINiS.
4. Remove the screws on each side that secure the
blower housing to the frame. As the blower hous
ing and tractor are tipped apart, roll the blower
drive belt off the engine sheave between the
sheave and belt finger. This can be easily done by
pulling the recoil starter rope to rotate the engine
sheave. With the belt disconnected, the blower
housing may then be lifted from the frame.

of the blower housing. To replace this belt, hold the im
peller brake away from the belt and slip the belt from
the sheave. See Figure 5.
Replace the blower drive belt by slipping it into position
on the sheave, positioning the brake shoe on the belt.
