a. BEARINGS. Inspect bearings for free and smooth rotation, and broken or missing balls or rollers. Also look for tightness of fit in bearing bores. Inspect bearing races for wear and color changes due to heat.
b. 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, burrs, sharp edges, and signs of seizing.
(2) Check for dirt in oil holes and in bushing-type bearings. Oil holes and grooves must be clean and not damaged.
