Re: Half of a cotter pin in oil pan?
Back in the 50's I was a mechanic at a GMC dealership. Another mechanic had rebuilt a 503 engine. A few weeks later the owner brought it back to the shop because he had drained the oil and got a handful of broken cotter pins. The foreman gave me the job because mechanic #1 was on vacation. Not one of the rod nuts were loose, not even one! The problem was caused by the mechanic not driving the pin in with a hammer to
fully seat them before bending them over.
When A & B engines were being raced, the Ford rods had a bad reputation, and many aftermarket rods were made. I believe it was not the rod, it was the castellated nuts which have only 3 or 4 full threads, and they would strip-out. I raced Model B's for many years with B rods, but Cat or ARP nuts, never a problem and consistently turned the engine 6,000 to 6200 RPM.
