STEP 40:  (SEE FIGURE 40)
•  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.

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

Go to step 48 on page 21.

STEP 39:  (SEE FIGURE 39)
•  Remove the engine pulley keeper from the side of 

the tractor frame by removing the washer and nut 
that secure the keeper. Attach the new pulley keeper 
supplied with the snow thrower, reusing the original 
bolt, washer and nut.

NOTE: Some tractors may already be equipped with a
pulley keeper that is identical to the new one supplied.

•  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).
