Dry cleaning solvent P-D-680 is toxic and flammable. Always use in an open area
with good air flow, away from sparks, heat, or flames. Wear-goggles and gloves. Do
not breathe vapors. Avoid contact with skin, eyes, and clothes. If you get dizzy
while using solvent, breathe fresh air and get medical help. If solvent gets on
hands, wash them. If solvent gets in eyes, flush eyes with fresh water and get
medical help immediately. Keep fire extinguisher nearby.
If a gasket is being removed, scrape old gasket material and sealant off mating surface. Clean
mating surface with dry cleaning solvent Item 13, App C). Dry with wiping rag Item 61, App C).

removed parts must be inspected with care. Replace parts if damage or wear exceeds allowable limits.
GENERAL. Procedures for inspection will be the same for most parts. General inspection procedures are
given in steps b through p below. Special inspection procedures are covered in the task as needed.
(1) Inspect all castings and forgings for breaks, cracks, and wear or scoring that would impair function.
(2) Inspect machined surfaces for nicks, burs, and raised metal. Mark damaged areas for repair.
(3) Use straightedge to check all mounting flanges on housings and supports for bends. Inspect mating
flanges for stains which would indicate oil leakage.
(4) Inspect all threaded parts for damaged or stripped threads.
NEEDLE ROLLER BEARINGS. Inspect bearings for free and smooth rotation and broken or missing
rollers. Also look for tightness of fit in bearing bores. Inspect bearing races for wear and color changes due
to heat. See TM 9-214 for inspection procedures.
STUDS. Inspect all studs for stripped or damaged threads, bent or loose condition, and signs of stretching.
GEARS. Inspect gears for burs, wear, cracked or broken teeth, and pitting at tooth contact areas.
BUSHINGS AND BUSHING-TYPE BEARINGS.
(1) Check all bushings and bushing-type bearings for secure fit in casting. Check for color changes which
could mean overheating. Inspect for size, scoring, out-of-roundness, burs, sharp edges, and signs of
(2) Check for dirt in oil holes and in bushing-type beearings. Oil holes and grooves must be clean and not
