• Make sure the attachment clutch lever on the dash

• Pivot the upper idler arm so that it rests against the

stop bolt and is pointing toward the front as shown.
Screw the trunnion (II) along the threads of the
engagement rod until it is aligned at the front end of
the idler arm slot. Attach the trunnion (II) to the slot
using the 3/8" thin washer (W) and a 5/64" hairpin
cotter (JJ).

• 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.

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