STEP8.

Remove the cylinder driveshaft pulley (lower pulley):

Ag.6

IMPORTANT:
Exercise care at all times when attempting to remove the
pulley. The pulley is made of cast-iron and it could crack if
excessive or sudden force is applied to it with either a mallet

or a prying tool.

A. On the engine side of the cylinder shaft, rotate the lower
pulley until the two set screws

in

its shoulder are visible (see

Fig. 6). Using a

%2" hex key (Allen) wrench, remove the two

set screws.

B. Spray penetrating oil liberally into the two set screw holes.
Next spray the cylinder shaft

on

both sides of the pulley.

Allow theoil to soak

in

for several minutes.

C. Using a soft-head mallet, tap the pulley inward (toward
the main frame) until it loosenson theshaft.

~void

striking the
more fragile, outer edges of the pulley with the mallet. After
loosening the pulley, add more penetrating oil to the newly
exposed portion ofthe cylinder shaft.

D.

Slide the pulley outward and off the shaft using two flat
blade screwdrivers as levers behind the pulley to pry it off.
Use even pressure around the pulley to avoid cocking it on
the shaft. Save the pulley and its two set screws (removed

in

Step 8A) for reuse.

NOTE: On some machines, the location of the engine
mounting plate may prevent the pulley from being
removed from the cylinder shaft. If so, leave the pulley

on

the shaft and proceed to Step9.The pulley will be

removed later,

in

Step

17.

E.

Using pliers, remove the 1W'long rectangular key from

the keyway

in

the shaft (unless key remains inside the key-

way ofthe pulley). See Fig.

6.

If necessary, tap the key with a

mallet and apunch to help loosen

it.

Save the key for reuse.

F.

Wipe the shaft clean and remove any rust or burrs with

an
emery cloth. This step is critical as any rust or burrs could
prevent the shaft from being removed in the steps thatfollow.
Finally, thoroughly lubricate the shaft with penetrating oil.

STEP 9.

On the engine side of the cylinder shaft, loosen the set screw
in

the bearing locking collarusing a

1/a"

hex key (Allen) wrench.

Being careful to avoid any sharp edges on the cutting flails or
other metal parts (wear thick gloves for added protection),
reach down inside the shredder hopper and securely fasten a
clothesline or very strong twine around one of the cylinder
pins just behind the flywheel so the entire assembly will be
balanced. The rope or twine must

beingood condition (not

frayed or split) and

be

capable of supporting 40 or more
pounds. Pull the rope or twine taut to remove any slack and
securely fasten the upper end to a sturdy 2"x4" piece of wood

(see Fig. 10) spanning the shredder hopper. Tying up the

cylinder assembly

STEP 16.

Remove the two flangettes and the bearing between them by
prying out the innerf1angette with a screwdriver, orby tapping
the opposite end of the cylinder shaft with a soft mallet. If
necessary, apply penetrating oil to the shaft to help free the
bearing. Save the f1angettes, bearing and three locknuts and
screws forreuse.

STEP 17.

Remove the cylindershaft:
A. Note the position of the cylinder shaft relative to the hole

in

the shredder wall (see Fig. 11). The shaft mustbecen-

tered vertically

in

the hole of the main frame. If it isn't cen­tered, reposition the cylinder shaft by adjusting the length of
the rope or twine that supports the cylinder assembly.

B. On the engine side of the cylinder shaft, make certain that
the shaft

is

clean and free of any burrs or rust. It also must be

well-lubricated with oil. NOTE: If the pulley

is

still on the shaft,

be sure to clean and lubricate the shaft after the pulley

is

removedinStep D below.
C. Spray penetrating oil into the two screw holes in the cylin-

der assembly tube from which you removed the screws

in

Step 12 (seeFig. 9).
D.

On the engine side of the cylinder shaft, use a soft mallet
to tap the shaft a little toward the chipper side. As the shaft
moves forward, remove the pulley (if still on), its

key,

and the

locking collar if not doneso previously.
E.

Continue driving the shaft inward until the keyway end of

the shaft

is

flush with the slotted bearing sleeve on the engine
side of the main frame (see Fig. 12). Now spray additional
penetrating oil into the two screw holes mentioned in Step C
above.
