When assembling the belt under the tractor, hold this
manual above you so that you will be viewing the belt
diagram and the tractor from the same direction.
Assemble the short "V" belt onto the engine pulley
_sothat it passes between the pulley and the engine
pulley keeper. Next assemble the belt onto the
large rear pulley on top of the clutch/idler assembly,
passing it between the pulley and the keeper bolt
located beside the pulley. Position the idler pulley
against the outside of the belt. See figure 15.
Place tension on the belt, by pulling the left side
tensioning chain as far out as the assembled
hairpin cotter will allow. Secure the chain in this
position with a 1/8" hairpin cotter. See figure 15.
IMPORTANT: Make sure that the "V" belt is not
assembled around the outside of the engine pulley
keeper or the keeper bolt.
