clutch arm and insert the drilled end of the rod
through the arm. Secure with a 5/64" hairpin cotter.
Attach the two front pulley frame brackets to the inside
of the clutch/idler assembly using two 5/16" x 3/4" hex
bolts, 5/16" washers and 5/16" nylock nuts for each
bracket. Add extra washers if needed.
Insert a tensioning chain through the hole shown and
attach the end link to the spring on the lower idler arm.

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.
