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).

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

STEP 45:  (SEE FIGURE 44)

•  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. 
Place the belt to the inside of the other flat idler pulley.
