STEP 19:  (SEE FIGURE 18)

•  Hook the rear of the clutch/idler assembly onto the 

two shoulder bolts assembled to the outside 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 and 1/8" hairpin cotters.

STEP 18:  (SEE FIGURE 17)

•  Turn the clutch/idler assembly right side up.
•  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.

STOP

Did you choose the correct drive belt for 
your tractor? Using the wrong length belt 
may cause premature bearing or belt failure.

STEP 20:  (SEE FIGURE 19)

•  Assemble the drive belt onto the engine pulley. You 

may need to remove the belt from the large pulley on 
the clutch/idler assembly in order to assemble it onto 
the engine pulley. When re-assembling the belt onto 
the large pulley, be sure the belt is between the large 
pulley and the hex bolt next to it.

•  Place tension on the belt by pulling the left side 

tensioning chain out as far as the 3/32" hairpin cotter 
that was installed in the chain in step 15 will allow. 
Secure the chain in this position by inserting a 1/8" 
hairpin cotter through the chain.

NOTE;

  To prevent the chain from dragging on the

ground, loop the end of the chain though the pivot lock
pin. Refer to figure 56 on page 23.
