• 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.

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.
• Go to step 48 on page 21.
