Make sure the attachment clutch lever on the dash panel is in the disengaged (down) position. Position the idler arm so that it points straight forward, as shown in figure 10. Align the engage- ment rod trunnion with the hole in the idler arm by screwing the trunnion in or out on the rod. Attach the trunnion to the idler arm using a 5/64" hairpin cotter. See figure 10.

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.

Hook the extra spring through the end of the tensioning chain.•See figure 13.
Assemble the spring and a 3/8" hex lock nut onto the bottom of the bolt and nut which secures the
idler pulley to the upper idler arm. Hold the bolt head and tighten the 3/8" hex lock nut, leaving it loose enough for the spring to pivot freely between the two nuts. See figure 13.
Attach a 3/32" hairpin cotter to the chain, placing it in the fifth link from the spring. See figure 13.
