The procedures for inspection will be similar for most components and parts of the engine. Any
inspection procedure that is peculiar to a specific part or component is covered in the paragraph
relating to that item.
Inspect all castings for cracks using a magnifying glass and strong light. Particularly check the
areas near studs, pipe plugs, threaded inserts, and in sharp corners and fillets.
Inspect machined surfaces of castings for nicks, burrs, and raised metal. Mark damaged areas
Check all mating flanges on housings and supports for warpage using a straightedge or surface
plate. Inspect mating flanges for discoloration which may indicate constant oil leakage.
Inspect all pipe plug and capscrew tapped openings for damaged or stripped threads.
Check actual casting specifications against those given in the paragraph relating to the item.
Refer to TM 9-214 for inspection of bearings. Check actual bearing specifications against those given
in the paragraph relating to the item.
Inspect all studs for stripped or damaged threads, bent or loose condition, and signs of stretching.

Inspect all gear teeth for wear, sharp fins, burrs, and galled or pitted surfaces.
Check actual gear specifications against those given in the paragraph relating to the item.
BUSHINGS AND BUSHING-TYPE BEARINGS
Check all bushings and bushing-type bearings for secure fit in the castings or mating part in
which they are used.
Inspect for wear, burrs, nicks, and out-of-round condition.
Check for dirt in lubrication holes or grooves. Holes and grooves must be clean and free from
damage to ensure proper lubrication.
Check actual bushing or bushing-type bearing specifications against those given in the para-
