9. Move the wheel drive belt off the jackshaft pulley.
Make sure that it is moved to the right hand side of
the pulley.

10. Slide the jackshaft and the wheel shaft to the left
until the right-hand ends of both shafts are free. A
bushing and spacer(s) will fall off the right-hand side

of the jackshaft. Save them, since you’ll need to
reinstall them later.

HINT: Use a soft-faced hammer on the right-
hand end of the wheel shaft if it is tough to
remove. Use the hammer and the large straight
punch to tap the jackshaft to the left if you
cannot easily move it by hand.

11. Use the 5/16-inch wrench to remove the bolts

that secure the wheel drive belt cover to the mower.

secures the engine Power Take Off (PTO) pulley to
the engine’s PTO shaft.

13. Slide the PTO belt guide, the wheel drive belt, and

the PTO pulley off the engine’s PTO shaft. Take the belt off
the pulley.

14. Move the wheel drive belt around the right-hand
end of the jackshaft and the wheel shaft. Push the

wheel drive belt to the rear and remove it from the

mower.

To install the wheel drive belt:

NOTE

If you’re installing a new belt, close up the
adju.ster in the middle of the wheel drive control
cable. Also screw in the adjuster on the lower
end of the control cable. Refer to Steps 1 through
4 of "Wheel Drive Initial Setting”.

1. Check the engine PTO shaft to make sure that

there is a felt washer installed on the PTO shaft.
Replace the felt washer if necessary (See the Parts
Catalog for replacement information.)

2. Push the front end of the wheel drive belt beneath
the wheel drive idler pulley and then forward into the
mower’s chassis. Loop the wheel drive belt around

the PTO pulley and then slide the PTO pulley onto the

engine’s PTO shaft.

3. Rotate the PTO pulley on the engine PTO shaft

until the PTO pulley cotter pin holes align with the

cotter pin hole through the engine PTO shaft. We

recommend that you install a new cotter pin through

the holes. Use the pliers to bend the legs of the cotter

pin around the PTO pulley hub so that the cotter pin
can’t come out. See Photo 5-16.
