5.4-9 Fly Boom Section Removal
1.
On the platform end of the boom, mark and
remove the slave cylinder hoses on the top
side of the fly boom tip. Crack the lines slowly
to relieve any residual pressure. Use a suitable
container or rags to catch any oil spillage. Cap
hoses and ports to keep them clean.
2.
Remove the fasteners for the cable/hose tube
support on the side of the fly boom.

3.
Remove the top and side wear pads and shims
inside the platform end of the mid boom.
Store the shims with their repective parts for
reassembly later.
M62255AA
4.
Place a suitable stand that can bear the weight
of the fly boom ahead of the machine. Attach
a lifting sling to the tip of the fly boom. Lift it up
slightly, then remove the bottom wear pad.
M62256AA
5.
Lift/slide the fly boom out 2/3 of the way. Pull it
out straight to avoid binding. Set it down on the
stand to re-sling as required. Balance the load
as it is being removed.
NOTE
All the wear pads must be removed from the
platform end of the mid boom so the fly boom
section can be pulled all the way out. The wear
pads on the counterweight end of the fly boom
section would otherwise prevent removal.
6.
Slide the fly boom completely out of the mid
boom and set it down on suitable blocking.
7.
Replace the wear pads on the counterweight
end of the fly boom. Use Loctite 242 or 243 on
the wear pad fasteners.
