For additional information on cleaning procedures and materials, refer to TM 3-247, Materials Used for Cleaning,
Preserving, Abrading, and Cementing Ordnance Materiel and Related Items Ir'eluding Chemicals.
Cover parts after cleaning to protect them from dust and debris, Parts that can rust should be lightly oiled.
Inspect parts to find out which parts can be used and which parts must be replaced. Specifications and tolerances are
given in this manual, but sometimes you, the inspector, must make the decision which parts are good, and which parts
must be replaced.
To find out if you can use a part that is otherwise in good condition, check the c earance between mating surfaces. If
clearance is within tolerance, the part may be used.
Carefully look at all machined surfaces and polished areas. Use a strong light to shine across polished surfaces to
check for score marks, cracks, and other signs of wear.
Inspect gears for cracked, chipped, and worn down teeth. Look for metal-to-mete I wear marks and pitting. When a gear
is found to be damaged, replace it and its mating gear.
