INSTALLING CLUTCH/IDLER ASSEMBLY

Turn the clutch/idler assembly upside down and place the extra tensioning chain through the hole shown in figure 11.

USE THIS HOLE

FIGURE 11

Hook the loose spring through the end of the tensioning chain. See figure 12.

Hook the other end of the spring onto the bottom of the bolt and nut which secure the idler pulley to the upper idler arm. Hold the bolt head and assemble a 3/8" hex lock nut onto the bolt, leaving it loose enough for the spring to pivot freely between the two nuts. See figure 12.

Attach a 3/32" hairpin cotter to the chain, placing it in the fifth link from the spring. See figure 12.

Assemble the short "V" belt onto the engine pulley and then onto the large pulley on the clutch/idler assembly. The belt must be placed to the inside of

the idler pulley and the keeper bolt. See figure 14. IMPORTANT: Do Not assemble the "V" belt

around the outside of the keeper bolt.

Place tension on the belt by pulling the left side tensioning chain out as far as the 3/32" hairpin cotter will allow. Secure the chain with a 1/8"

hairpin cotter. See figure 14.

Hold this drawing above you while viewing the Clutch/Idler Assembly from underneath the tractor. Right and left in the drawing will be the reverse of the viewer's right and left.
