Boom
b. Retract Chain Removal and Replacement
1. Park the vehicle on a hard, level surface.
2. Fully retract the boom and raise the boom to a
horizontal position. Place the travel select lever in
(N) NEUTRAL, move the neutral lock lever to
NEUTRAL LOCK position, engage the parking brake
switch and shut the engine OFF.
3. Remove the thumbscrew (21), lockwasher (20) and
flat washer (19), holding the rear cover (18) to the
rear of the outer boom (17). Lift the rear cover
straight up until the capscrew in the top of the cover
clears the retaining hole in the top of the outer boom.
Remove the cover from the outer boom.
4. At the front underside of the boom, record the amount of
threads extending beyond the elastic locknut (22).
This measurement will be the starting point for
adjustment of the boom retract chain.
5. At the front underside of the outer boom, loosen the
elastic locknut (22) far enough so that it can be
removed by hand.
6. If the chain clevis has a threaded hole on the
end (25), a string or wire can be attached to the
retract chain clevis using a threaded eye (26) or a
flat washer tack welded to a capscrew (27). The
outside diameter of the eye or flat washer must be
smaller than the diameter of the threads on the
clevis. The string or wire will be used to pull the
chain back through the boom during the reassembly.
If there is not threaded hole on the end of the clevis,
you will need to use a phillips screwdriver to catch the
end of the clevis and guide it through the tab during
reassembly.
7. Remove the elastic locknut (22) and flat washer (23)
holding the retract chain threaded clevis (24) to the
mounting tab. Save the flat washer and discard the
elastic locknut.
8. If a threaded eye or capscrew with flat washer
(26 or 27) was installed in step 6, attach a string or
wire to the eye or flat washer on the end of the
retract chain clevis. The string or wire must be long
enough to pull the clevis and chain through the outer
boom.
