STEP 20: (SEE FIGURE 19)

Assemble the drive belt onto the engine pulley first and then onto the large pulley on top of the clutch/ idler assembly. Place the belt to the inside of the idler pulley and the belt keeper bolt located beside the large pulley.

Place tension on the belt by pulling the left side tensioning chain (PP) out as far as the 3/32" hairpin cotter in the chain will allow. Secure the chain in this position by inserting a 1/8" hairpin cotter (KK) through the chain.

IMPORTANT: Do Not assemble the drive belt around the outside of the keeper bolt beside the large pulley.
