Slowly pivot the rear half of the snowthrower
back. Rest the handlebars on a stable object.
5.
Take the
auger
drive belt (Figure 5-8, Item P) off
the engine
auger
drive pulley (Figure 5-8, Item Q).
You
may have to loosen the bolt that secures the
belt guide (Figure 5-8, Item
S)
to the back of the
engine and move the belt guide out of the way.
6. Loosen the bolts that attach the belt guides to the
front of the chassis below the transmission pulley.
Turn these belt guides to give you room to take
the wheel drive belt off the transmission pulley.
7.
You
may
have to loosen the bolt that secures the
engine pulley belt guide (Figure 5-5, Item

in
place and turn this belt guide
out
of the way.
8. Take the wheel drive belt off the transmission
pulley and engine wheel drive pulley.
To
install the wheel drive belt:
1.
Place the wheel drive belt on the engine wheel
drive pulley and transmission pulley.
2. If you had to loosen the bolt that secures the
engine pulley belt guide (Figure 5-5, Item
R)
in
place, position the leg of this belt guide approxi-
mately 1/16-inch from the outer surface of the
wheel drive belt and tighten the bolt that secures
it to the
back
of the engine.
3. Rotate one of the two belt guides that is below the
transmission pulley so that its
"leg"
is 1/16-inch
away from the outer surface of the wheel drive
belt. Hold the belt guide in this position and
22
tighten the bolt that holds the belt
guide
in place.
Repeat this step for the remaining belt guide.
4. Retighten bolt that attaches belt
guide
(Figure 5-8,
Item

to engine.
5. Move the rear half of the snowthrower close to the
front half. Place the
auger
drive belt onto the
engine
auger
drive pulley (Figure 5-8, Item Q).
6. Move the snowthrower halves together. Align the
four attachment holes (two in each side of the
frame). Loosely install the four screws (Figure 5-8,
Item Q) that secure the halves of the snowthrower
together. Then firmly tighten the screws.
7.
Reinstall the worm
gear
and support (Figure
5-7,
Item M) to the left-hand side of the snowthrower.
Firmly tighten the bolt (Figure
5-7,
Item N) that
holds it in place. Rotate the chute control
crank
to
make sure that the deflector
chute
turns freely. If it
doesn't, loosen the bolt (Figure
5-7,
Item N) and
adjust the support inward
or
outward so that the
chute doesn't bind.
8. Adjust the wheel drive cable. See
"Wheel
Drive
Cable Adjustment".
