Piston Pin Inspection.

5.

For connecting rod, check for visual damage. Discard if rod is bent, had previous bearing failure, was

overheated (blued) at top or bottom end, or is fretted at split line between rod and cap.

6.

Check for cracks using the magnetic particle inspection method (reference ASTM E1444).

NOTE

Overheated bushings may become loose and creep together, thus blocking off supply of

lubricating oil to piston pin and spray nozzle.

7.

Check connecting rod bushings for indications of scoring, overheating, or other damage.

WARNING

Compressed air used for cleaning purposes will not exceed 30 PSI (207 kPa). Use only

with protective equipment (goggles, face shield, gloves, etc.). Failure to comply may result

in injury to personnel.

8.

Check spray nozzle at upper end of connecting rod for plugged holes. Blow compressed air through drilled

oil passage in rod to ensure spray nozzle holes are open.

9.

Inspect connecting rod bearing bores for burrs or foreign particles. Clean up minor burrs with crocus cloth

using circular motion.
