10. Inspect wear and condition of the booms, chains,

clevis’, chain sheaves, extend/retract cylinder, chain

rods, clevis anchors and all mounting hardware.

Replace any worn or damaged parts. DO NOT

attempt to make any repairs to the chain.

IMPORTANT: Chains and clevis’ are wear items and

experience the same stress. DO NOT attempt to service

or repair a chain or clevis. Replacement chains are

shipped pre-assembled with new clevis’.

Extend Chain Installation

1. Coat the threads of the threaded clevis (Fig. 3-114, 1)

with multi-purpose grease.

2. Lay the new extend chain (Fig. 3-114, 2) on top of

the outer boom (3) with the threaded clevis (1)

toward the front of the boom.

3. Attach the wire (Fig. 3-114, 4) to the threaded clevis

(1) of the new extend chain. Loop the wire through

the clevis and twist together to form a loop.

4. Pull the extend chain forward and place over the

right side of the chain sheave (Fig. 3-114, 5). Guide

the wire and the threaded clevis into the boom by

placing the threaded clevis under the chain sheave

and in between the top of the inner boom (6) and the

intermediate boom (7).

5. While one person guides the extend chain into the

front of the boom, a second person should pull the

wire (Fig. 3-115, 1) and threaded clevis toward the

rear of the boom. Guide the threaded clevis (2) into

the hole in the anchor plate (3).

6. Place the 3/4" flat washer (Fig. 3-115, 4) onto the

threaded end of the threaded clevis and install a new

3/4-16 elastic locknut (5). Thread the elastic locknut

onto the threaded clevis until the threads are flush

with the top of the nut.

7. Pull the anchor clevis (Fig. 3-116, 1) up around the

double chain sheave and position the clevis between

the yoke plates (2).

8. Coat the hex-socket head capscrew (Fig. 3-116, 3)

with anti-seize compound. Insert the capscrew

through the yoke plates and clevis, and secure in

place with a new 3/8-16 elastic locknut (4). Tighten

securely, but ensure that the chain clevis pivots

freely.
