## Discrepancy

DISASSEMBLING ENGINE FOR SEALING OIL LEAKS.  WHEN NR 3 PISTON PIN WAS PUSHED OUT IT WAS FOUND BROKEN IN HALF RIGHT IN THE MIDDLE OF THE CONNECTING ROD BUSHING.  FOUND LIGHT (0.002 INCH - 0.003 INCH DEEP) SCORING IN CONNECTING ROD BUSHING. APPARENTLY, THE PIN HAD NOT BEEN BROKEN FOR LONG.  REMAINDER OF CYLINDER ASSY APPEARED NORMAL.  NO SIGNIFICANT DIFFERENCE FROM OTHER 5.  PLAN TO SUBMIT PIN TO U. OF T. METALLURGY LAB FOR ANALYSIS.  APPEARS TO BE METAL DEFECT.
