Boom
53. Remove the capscrews (15) and lockwashers (16)
holding the lower side wear pads (17) and
shims (18) to the side of the inner boom. The front
capscrews will also hold the mounting clips (19) for
the hose channel assembly to the side of the inner
boom. Label the wear pads and shims as “Inner
Boom Lower Side.” Save the shims, capscrews,
lockwashers and wear pad inserts (20).
54. Carefully slide the hose channel assembly out the
rear of the inner boom. Place the hose channel
assembly on a level surface. Unless the hose
channel assembly has been damaged, there is no
need to disassemble the hose channel assembly.
55. If the hose channel has been damaged, disassemble
the hose channel assembly to replace any parts that
are bent or twisted:
a. Remove the capscrews (21) and
lockwashers (22) holding the mounting clips (23)
to the channels (24). Remove the retainer
nuts (25) from the mounting clips.
b. At the front of the hose channel assembly,
remove the capscrews (26) and elastic
locknuts (27) holding the channels to the front
guide (28). Save all hardware and discard the
elastic locknuts.
56. Carefully lower the inner boom onto suitable
supports, or to the ground.
57. Inspect the boom and welds. Consult the local Sky
Trak distributor or the JLG Service Department at
1-877-554-5438 or 1-717-485-6657, if structural
damage is detected.
58. Inspect hoses, hardware, wear pads, mounting
points, chains and other components visible with the
inner boom removed. Replace if damaged.
59. Inspect all wear pads for wear. (Refer to Section
3.9.1, “Wear Pad Inspection.”)
