What was found
UPON INSPECTION OF CAMS IN IMPULSE COUPLINGS FOR WEAR PER AD 78-09-07, FOUND ONE FLYWEIGHT AND RIVET WORN WELL BEYOND LIMITS. THIS IS NEW STYLE CAM WITH SNAP RING ASSEMBLY. FOR A TOTAL TIME OF ONLY 595 HOURS, FEEL THIS TO BE SIGNIFICANT WEAR AND WOULD ALSO QUESTION THE HARDNESS OF METAL.
