Installing Push Arms,
Torsion Springs and Bushings
1. Apply grease to inside and outside of new bushings.
Using
a hammer and flat plate, carefully drive the bush-
ings into the push arm pivot tubes. The bushings must
be flush with the end of the tube.
2. Inspect the torsion springs. If the springs are dam-
ag
ed, use new springs when assembling the parts.
3. Slide the torsion springs onto the inside of the push
ar
m pivot tubes. Install the washers, push arms with
springs and push arm brackets onto the pivot shaft.
Install the roll pins to secure the parts in place.
4. Raise the push arm and pivot shaft assembly into
po
sition and secure it in place with cap screws, support
plate, reinforcement support and locknuts. Make sure
the springs contact the retainer plate on the push arms
and the underside of the frame.
5. Have a helper push down on the left push arm while
you
place a 3 ft. long block of wood between the chassis
and to top of the push arms, across the full width of the
machine.
NOTE: After the wood block is installed, there should be
en
ough clearance for installing the ball joint into the front
of the push arm.
6. Thread jam nut fully onto the left-hand ball joint.
Scr
ew the ball joint into the left-hand push arm until the
center of the ball joint is 2.25 inches away from the front
of the push arm. Do not tighten the jam nut until the deck
is mounted.
7. Install the brake mount and pedal assembly with cap
scr
ews, locknuts, carriage bolts, lock washer and nuts.
Route the right-hand brake cable through the hole in the
right-hand push arm bracket. Connect the cable to the
brake strut with the clevis pin and the tension spring.
Hook the opposite end of the tension spring into the hole
in the side of the chassis. Also install the cable into the
mount on the frame.
