Inspection.
(1)
Inspect all metal parts for dings, gouges, abrasions etc. On all parts except the ball (10), use 320 grit paper
to smooth and remove sharp edges. If ball (10) is damaged (scratched, gouged, etc.) it should be replaced.
(2)
Check the groove (round bottom) in the inlet for burrs on the corners. If groove is worn such that burrs
exist, use 320 grit paper to smooth and remove sharp edges.
(3)
Inspect the small spring-loaded continuity ball (36) located in the face of the unit. Push the ball in and be
sure that it pops back into place. If the ball does not pop back freely, electrical continuity is lost and static
discharge is possible. Replace entire coupling if continuity ball does not pop back out.
(4)
Inspect screw (6) and handle (9) for damage. If either part is bent, replace it.
WARNING
Dry cleaning solvent, P-D-680, Type III, is potentially dangerous to personnel and
property. Eye and skin protection is required. Avoid repeated and prolonged skin
contact. Wash hands immediately after exposure. Do not use near open flame or
excessive heat. Use only in areas with good ventilation.
Rubber gloves should be worn when handling fueling system components due to the
toxic effects of some fuel additives and the dry cleaning solvent.
(5)
Make certain all components are clean and free from oil, grease, or dirt. Wash all parts with an approved
dry cleaning solvent and dry thoroughly with a clean, lint-free cloth.
