Remove Bottom Wear Pad
NOTE
All the wear pads must be removed from the
platform end of the mid boom so the y boom
section can be pulled all the way out. The wear
pads on the counterweight end of the y boom
section would otherwise prevent removal.
8. Slide the y boom completely out of the mid boom
and set it down on suitable blocking.
9. Replace the wear pads on the counterweight end
of the y boom. Use Loctite 242 or 243 on the
wear pad fasteners.

Mid Boom Section Removal
Procedure:
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 y
boom is removed.
