If your tractor has an electric attachment clutch go to step 14 on page 11.

STEP 7: (SEE FIGURE 7)

Attach the pulley (long end of hub facing down) and the large spacer (SS) to the hole shown in the clutch/ idler assembly. Use a 3/8" x 3-1/4" hex bolt (B), a 3/8" washer (X), a 3/8" lock washer (S) and a 3/8" hex lock nut (DD).

STEP 10: (SEE FIGURE 10)

Two different length drive belts are included with your snow thrower. Tractors with manual attachment clutches and single front deck suspension brackets use the 56" drive belt with #48138 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. Place the belt to the inside of the other flat idler pulley.
