23. Remove the elastic locknut (18) and capscrew (19)
holding the quick attach pivot pin (20) to the quick
attach assembly (21). Save the capscrew and
discard the elastic locknut. Place a support under
the quick attach assembly to prevent it from dropping
when the pivot pin is removed.
24. Use a brass punch and a rawhide hammer to
remove the quick attach pivot pin (20) from the quick
attach assembly and the bushings in the gooseneck.
Record the location and quantity of the shim
washers (22 and 23) as the pin is being removed.
Save the washers (22 and 23) from each side of the
quick attach.
25. Inspect the pin for nicks or surface corrosion. Use
fine emery cloth to repair minor nicks or corrosion. If
damaged and if it cannot be repaired, the pin must
be replaced.
Note: The Attachment Tilt cylinder is heavy. Use a hoist
and sling to support the Attachment Tilt cylinder when
the base end pin is removed.
26. Remove the retaining ring (24) from one side of the
base end pivot pin (25). Save the retaining ring. Use
a brass punch and a rawhide hammer to remove the
base end pivot pin from the inner boom
gooseneck (26).
27. Inspect the pin for nicks or surface corrosion. Use
fine emery cloth to repair minor nicks or corrosion. If
damaged and if it cannot be repaired, the pin must
be replaced.
28. Lower the Attachment Tilt cylinder (27) with the hoist
and remove from the backside of the gooseneck.
Place the Attachment Tilt cylinder on a clean, level
surface.
29. Pull the inner boom straight out of the intermediate
boom. Reposition the slings as needed so the inner
boom balances when removed from the intermediate
boom. Set the inner boom down on a hard, level
surface. Support the boom as needed to prevent it
from tipping over.
