Boom
3.72 Model 8042, 10042, 10054 Legacy Rev. 03/04
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.
39. Remove the retaining ring (1) from one side of the base
end pivot pin (2). Save the retaining ring. Use a brass
punch and rawhide hammer to remove the base end
pivot pin from the inner boom gooseneck (3).
40. Inspect the pivot pin (2) 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.
41. Lower the Attachment Tilt cylinder (4) down with the
hoist and remove from the rear of the gooseneck.
Place the Attachment Tilt cylinder on a clean, level
surface until installation.
42. Pull the inner boom straight out of the secondary
intermediate boom. Guide the four hose ends into the
rear of the boom as the inner boom is being
removed. Reposition the slings as needed so that the
inner boom balances when removed from the
secondary intermediate boom. Set the inner boom
down on a level hard surface. Support the boom as
needed to prevent it from tipping over.
43. At the rear of the inner boom, remove the elastic
locknut (5) and flat washer (6) holding the threaded
clevis on the inner boom extend chain (7) to the clevis
anchor. Pull the threaded clevis from the anchor, and
remove the extend chain from the inner boom. Save the
flat washer and discard the elastic locknut.
44. At the rear of the inner boom (8), remove the
capscrews (9) and lockwashers (10) holding the top
wear pads (11), spacer (12) and shims (13) to the top of
the inner boom. Label the wear pads, spacers and
shims as “Inner Boom Top Left” and “Inner Boom Top
Right” sides. Save the spacers, capscrews,
lockwashers and wear pad inserts (14).
