5.4-10 Mid Boom Section Removal
1. Place blocking inside the cable/hose tube to
support the e-chain track when the main support
bolt is removed. Cut the blocks about 5" (12 cm)
high. Place them about 4 ft (1.2 m) apart.
2. Remove the main power track carrier bolt from
the platform end of the mid boom. Allow the
cable/hose tube to rest on the blocking. Secure
it with a strap.
3. Locate the limit switch on the left-hand side of
the main boom, at the platform end of the lower
e-chain tube. Pull in the limit switch arm and
place a piece of tape over the switch hole. The
tape prevents the switch from being damaged
as the fly boom is removed.
4. Place a suitable stand that can bear the weight
of the mid boom about 2/3 the boom length
ahead of the machine.
5. Connect lifting slings to the platform end of the
mid boom.

inside the platform end of the main boom.
Store the shims with their respective parts for
reassembly later.

8. Set it down on the stand and re-sling to lift from
two points.

shims from the platform end of the main boom.
