Gripping Cam (SC-50 or SC-42, Fig. 7) Inspection
a.) Inspect the gripping cam(s) for chipped or worn teeth. The teeth
must be sharp and free of foreign matter.
b.) Inspect pin holes for elongation and wear.
c.) For the SC-50, inspect the connecting arms for distortion and
fractures. Inspect the pin holes for elongation and wear. The
gripping cam should pivot freely in assembly.
Warning: Replace cam assembly (SC-50) or gripping cams
(SC-42) with worn or damaged teeth, that contain fractures, and
cams and cam arms that have elongated pin holes.
7.
Gripping Cam Connecting Link (SC-46, Fig. 7) Inspection
a.) Inspect pin holes for elongation and wear.
b.) Inspect the gripping cam connecting link for distortion and
fractures.
Warning: Replace gripping cam connecting link that is distorted,
fractured, or if pin holes are worn or elongated.
8.
Shackle Pin (SC-12), Connecting Cam Pin (SC-35), Connecting
Yoke Body Pin (SC-37), Gripping Cam Connecting Pin (SC-44),
and Gripping Cam Body Pin (SC-54) Inspection (Refer to Fig. 7)
a.) Inspect all pins for:
Distortion
Surface blemishes
Wear
Fractures
Warning: Replace pins that are distorted, have surface scars, are
worn, or contain fractures.
9.
Connecting Yokes (SC-80, Fig. 7) Inspection
a.) Inspect pin holes for elongation and wear.
b.) Inspect the connecting yokes for distortion and fractures.
c.) Inspect lock ear area where the lock engages for wear. If worn the
clamp may not fully lock open with the gripping cam(s) (SC-50 or
SC-42) out of the jaw area.

10.
Lock Spring (SC-61, Fig. 7) Inspection
a.) Inspect the lock spring for distortion. The lock spring must have
a de
fi
nite amount of tension when the lock is moved to the lock
closed position, with minimal material in the clamp. The lock
must rest on the stop (B, Fig. 5).
Warning: Replace the lock spring if it is damaged, distorted, or
lacking in spring tension.
11.
Lock Assembly (SC-65, Fig. 7) Inspection
a.) Inspect the lock assembly for damage and wear. Inspect area that
engages connecting yoke (SC-80) for wear or distortion. If worn the
clamp may not fully lock open with gripping cam(s) out of the jaw.
b.) Inspect the lock assembly for binding. The lock assembly should
pivot freely. Binding indicates worn parts and/or foreign matter in
the assembly.
Warning: Replace lock assembly if any parts are worn or
damaged,
fi t loosely in the body hole, or do not have a defi nite
lock closed or locked open position.
12.
Body Bolt and Body Spacer (SC-16, Fig. 7) Inspection
a.) Inspect the body bolts and body spacers for wear at the position
where the body spacer contacts the lifting shackle (SC-10, Fig. 7).
b.) Inspect the body bolts for wear or damage.
c.) When replacing body bolt, tighten nut on bolt until the nut is
securely against the clamp body & the body spacer cannot rotate.
Warning: Replace body bolt & nut and body spacer if worn or
damaged.
13.
Clamp Assembly Inspection
a.) After re-assembling the clamp, check the operation of the clamp.
All parts should move freely without binding. Refer to the exploded
view (Fig. 7) of the clamp for proper location of all component
parts.
Warning: All retaining pins and fasteners must be in place.
