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 so that 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 11. IMPORTANT: Make sure that the "V" belt is not assembled around the outside of the engine pulley keeper or the keeper bolt.
