purpose grease.
13. Lay the new extend chain on top of the fourth boom
section with the threaded clevis toward the front of
the boom.
14. Attach the wire to the threaded clevis of the new
extend chain with a threaded eye or a flat washer
tack welded to a capscrew. The outside diameter of
the eye or flat washer must be smaller than the
diameter of the threads on the clevis.
15. Pull the extend chain forward and place in between
the chain sheave mounts. Guide the wire and the
threaded clevis into the boom by placing the
threaded clevis between the third boom section (5)
and the top of the fourth boom section (6).
16. Have an assistant guide the extend chain into the
front of the boom while pulling the wire and threaded
clevis into the hole in the anchor plate.

threaded clevis and assemble the locknut. Thread
the locknut onto the threaded clevis until the threads
are flush with the top of the nut.

19. After the chain is replaced inside the boom,
assemble the sheave to the mount at the front of the
third boom section.

at the front of the third boom section. Insert the
sheave pin through the mounts and the sheave.
Secure in place with the capscrew, saved, and a
locknut. Tighten securely.
21. After the sheave is assembled, apply a good grade
of multi-purpose grease to the grease fitting at the
end of the pin. Turn the sheave by hand to distribute
the grease evenly.
22. Pull the extend chain up and around the sheave at
the front of the third boom section.
23. Place the extend chain clevis between the mounting
plates at the front of the third boom section. Coat the
saved shoulder bolt with anti-seize compound and
insert through the plates and clevis. Secure the
shoulder bolt in place with a locknut. Tighten
securely, but the chain clevis should pivot freely.
24. At the rear of the boom, tighten the locknut on the
extend chain clevis until the amount of threads
protruding beyond the locknut is the same as the
measurement recorded during removal of the extend
chain.
