22. On the right side boom pivot mounting plate, locate

the boom sensor (Fig. 3-41, 1). Remove the hex nut (2)

on the inside of the mounting plate. Remove the boom

sensor from the outside of the plate, re-thread the

nut onto the sensor and allow the sensor to rest on

top of the frame, next to the mounting plate. The sensor

can remain connected to the harness.

Note: Use a hoist capable of lifting 5,000 lbs (2268 kg) and

two slings. Place the slings around the outer boom. The

slings should be placed far enough apart on the outer boom

so the boom will balance when the boom lift/lower cylinder

mounting pins and pivot pins are removed in the following

steps.

23. Remove the capscrew (Fig. 3-42, 1) and elastic

locknut (2) holding the upper lift/lower cylinder pivot

pin (3) to the outer boom. Securely block the lift/lower

cylinder in position. Remove the pivot pin from the pin

mount by pulling the pin out. It may be necessary to use

an appropriate puller threaded into the pivot pin to

remove the pin. Discard the elastic locknut and retain

the capscrew.

24. Inspect the pivot pin (Fig. 3-42, 3) for nicks or

damage. If the pin is damaged, it must be replaced.

25. Repeat Steps 23 and 24 to remove the other lift/lower

cylinder.

26. Remove the capscrews (Fig. 3-43, 1) and elastic

locknuts (2) holding the boom pivot pins (3) to the

frame. Use a brass punch and a rawhide hammer to

remove the pivot pins from the frame. While removing

the pins, note the location, quantity and size of the

shims (4) between the outer boom and frame.
