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

STEP 10: (SEE FIGURE 10)

• Two different length drive belts are included with your

snow thrower. Use the longer, 56" drive belt (

#48138

)

on tractors with manual attachment clutches.

• 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.
Place the belt to the inside of the other flat idler pulley.

the large 3/8" spacer to the clutch frame. Use a 3/8" x
3-1/4" hex bolt, a 3/8" washer, a 3/8" lock washer and a
3/8" hex lock nut.

• Insert a tensioning chain through the hole shown and

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