ELECTRIC ATTACHMENT CLUTCHES

Turn the clutch/idler assembly upside down and place the extra tensioning chain through the left front hole as shown in figure 19.

TENSIONING CHAIN

FIGURE 19

Hook the loose spring through the end of the tensioning chain. See figure 20.

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 20.

Attach a 3/32" hairpin cotter to the chain, placing it in the fifth link from the spring. See figure 20.

Assemble the short "V" belt onto the engine pulley and then onto the large pulley on top of the clutch/ idler assembly. The belt must be placed to the inside of the engine pulley keeper, the idler pulley and the keeper bolt located beside the large pulley. See figure 22 on page 13.

Place tension on the belt by pulling the left side tensioning chain out as far as the 5/64" hairpin cotter will allow. Secure the chain in this position by inserting a 1/8" hairpin cotter through the chain. See figure 22 on page 13.

IMPORTANT: Do Not assemble the "V" belt around the outside of the engine pulley keeper or the keeper bolt.
