INSTALLATION - CONTINUED
CAUTION
Never hammer directly on the pivot shaft flanges. Always use a wooden block or damage will occur to
the pivot shaft.
NOTE
Ensure pivot shafts are clean.
When installing pivot shafts, slots in pivot shaft for retaining bolt must be aligned with bolt hole
in tophandler.
Remove the lockwashers from the retaining bolt and place on one of the jackscrews. Insert the
jackscrew through the slot and into the retaining screw bolt hole. Use the jackscrew to draw the
pivot shaft into the boom. It may be necessary to tap on the pivot shaft with a 4x4 block and ham-
mer to aid in installation. Make sure the lockwashers are reinstalled back onto the retaining bolt
before installation.
It may be necessary to connect the hydraulic hoses and use tophandler controls to aid in boom-to-
tophandler positioning.
Turning the steering wheel while in crab steering will move the boom side to side for minor align-
ment adjustments. Boom movement is the opposite of steering wheel movement.
