STEP 33:  (SEE FIGURE 33)
•  Make sure the attachment clutch lever on the dash 

panel is in the disengaged (down) position.

•  Pivot the upper idler arm so that it rests against 

the stop bolt and is pointing toward the front as 

shown. Screw the trunnion along the threads of the 

engagement rod until it is aligned at the front end of 
the idler arm slot. Attach the trunnion to the slot using 

the 3/8" thin washer and a 5/64" hairpin cotter.

•  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.

•  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 32:  (SEE FIGURE 32)
•  Be sure to lift up the front end of the engagement rod 

as shown when performing the next operation. You 
can temporarily support the rod using a rubber band 
tied to the engine pulley keeper.

•  Attach the clutch/idler assembly to the tractor frame 

as follows. Hook the assembly's notched rear pulley 
frame brackets 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 and 1/8" 

hairpin cotters.
