STEP 35: (SEE FIGURE 35)

• Assemble the cable bracket (6) to inner part of the

double holes in the clutch/idler assembly using two
5/16" x 3/4" carriage bolts (L) and 5/16" nylock nuts
(Y). Use the two front holes in the cable bracket for
42" mower decks. Use the two rear holes for 46"
mower decks.

STEP 36: (SEE FIGURE 36)

• Attach the two rear pulley frame brackets (10) to the

inside of the clutch/idler assembly using two 5/16" x 1"
hex bolts (C), eight 5/16" washers (Q), and two 5/16"
nylock nuts (Y) for each bracket.

• Attach the two front pulley frame brackets (12) to the

inside of the clutch/idler assembly using two 5/16" x
3/4" hex bolts (D), 5/16" washers (Q), and 5/16" nylock
nuts (Y) for each bracket. Add extra washers if needed
in step 39.

• Insert a tensioning chain (U) through the hole shown

and attach the end link to the spring on the lower idler
arm.

• Install a 3/32" hairpin cotter (GG) in the 4th link of the

chain.

STEP 37: (SEE FIGURE 37)

• Two different length drive belts are included with

your snow thrower. Tractors with manual attachment
clutches and dual front deck suspension brackets use
the 55" drive belt with

#46989

printed on the outside

of the belt.

DO NOT USE

the other belt.

• Slightly loosen the hex bolt next to the flat idler pulley.

Install the drive belt down between the hex bolt and the
flat idler pulley with the flat side of the belt against the
pulley. Retighten the hex bolt.

• Loop the belt around the large v-pulley, placing it

between the v-pulley and the hex bolt next to the pulley.

STOP

Did you choose the correct drive belt for
your tractor? Using the wrong length belt
may cause premature bearing or belt failure.
