a. Component/Assembly Verification
The inner to intermediate boom separation should be
checked when assembling new boom sections or chains,
or when the rear retract chain clevis has been moved
forward on the anchor plate.
Measure the separation between the inner and
intermediate boom top plates, (Fig. 3 -125, 1). The
distance should be at least 8-1/2" (216 mm) and not
greater than 9-1/2" (241 mm) with the boom fully
retracted and the chains properly tensioned. A distance
of less than 8-1/2" (216 mm) could result in interference
and cause damage to boom components.
Figure 3-125 Measurement at Rear of Boom
If the distance is less than 8-1/2" (216 mm) or greater
than 9-1/2" (241 mm):
1. Verify that the retract chain clevis (Fig. 3 -126, 1) is
not mounted in the last hole (2) in the anchor
plate (3).

2. Make sure that the chain system is properly
tensioned. Refer to Section 3.4.3, “Boom Chain
Tension Check” and Section 3.4.4, “Boom Chain
Tension Adjustment.”
