STEP 47: (SEE FIGURE 46)
• Assemble the drive 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 idler pulley and the keeper bolt located beside the
large pulley.

• Place tension on the belt by pulling the left side

tensioning chain out as far as the 3/32" hairpin cotter
(FF) will allow. Secure the chain in this position by
inserting a 1/8" hairpin cotter (EE) through the chain.

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

STEP 46: (SEE FIGURE 45)
• Attach the clutch/idler assembly to the tractor frame

as follows. Hook the assembly's notched arms onto
the two shoulder bolts you assembled to the inside
of the tractor frame. Lift the front of the assembly and
attach it to the R.H. and L.H. hanger brackets using
two pivot lock pins (GG) and 1/8" hairpin cotters (EE).
