INSTALLING CLUTCH/IDLER ASSEMBLY

This section covers the installation of the Clutch/Idler assembly to tractors with attachment clutches that are either rod operated (p. 15), cable operated (p. 17) or electric (p. 19). Use the appropriate instructions for your tractor.

ROD OPERATED MANUAL ATTACHMENT CLUTCH

STEP 29: (SEE FIGURE 29)

Move the attachment clutch lever on the dash panel to the disengaged (down) position.

Screw the trunnion (II) onto the end of the snow thrower engagement rod.

Locate the clutch arm (where the mower clutch rod was connected) underneath the right hand side the tractor, just to the inside of the suspension arm. If there is an extension attached to the clutch lever, the extension, bolt and nut must be removed and stored with the mower deck.

IMPORTANT: Re-attach the extension to the clutch lever before reinstalling the mower deck.

Position the engagement rod to the inside of the clutch arm and insert the drilled end of the rod through the arm. Secure with a 5/64" hairpin cotter (JJ).

STEP 31: (SEE FIGURE 31)

Two different length drive belts are included with your snow thrower. Tractors with manual attachment clutches and dual front deck suspension brackets use the 55" drive belt with #46989 printed on the outside of the belt. DO NOT USE the other belt.

Slightly loosen the hex bolt next to the flat idler pulley. Install the drive belt down between the hex bolt and the flat idler pulley with the flat side of the belt against the pulley. Retighten the hex bolt.

Loop the belt around the large v-pulley, placing it between the v-pulley and the hex bolt next to the pulley.

STEP 30: (SEE FIGURE 30)

Attach the two suspension arms to the inside of the clutch/idler assembly using two 5/16" x 3/4" hex bolts (E), 5/16" washers (U) and 5/16" nylock nuts (CC) for each arm. Place the washers between the arms and the assembly frame.

Insert a tensioning chain through the hole shown and attach the end link to the spring on the lower idler arm.

Did you choose the correct drive belt for STOP your tractor? Using the wrong length belt

may cause premature bearing or belt failure.
