12. Twist the ends of the retraction cables to remove the
ends of the cables from the slots in the side of the
boom fly section.
13. From the rear of the boom, pull out the boom retrac-
tion cables.
Telescope Cylinder/Boom Cable
Installation
1. Attach the threaded end of the new retraction cables
to the tie wires used in the removal procedure.
2. From the front of the boom, pull the retraction cables
through the boom and through the attachment holes
in the bottom of the boom base section. Loosely
install the adjustment nuts and jam nuts.
3. Install new retract sheaves, then route the opposite
end of the retraction cables around the sheaves.
Push the ends of the cables through the slots in the
side of the boom fly section.
4. Install the sheave guards and secure them in place
with the retaining screws.
5. Pull the boom sections out to approximately where
they were extended to for telescope cylinder
removal.
6. Install a new extend sheave on the end of the tele-
scope cylinder.
7. Route new extend cables around the telescope cyl-
inder. Loosely fasten the threaded end of the cables
to the rod end of the telescope cylinder with the
adjusting nuts and lock nuts. Install the opposite
end of the cables in the cable mount block.
8. Use tape or tie straps to fasten the cables to the tele-
scope cylinder assembly. It is important that the tape
or straps be strong enough to hold the cable in
place yet weak enough to break and fall away when
the cables are adjusted.
