Specifically, connecting rod nuts. I installed my shiny new rebabbited rods, using modern 3/8 x 24 castle nuts...no problem. Then I started looking at all the original Ford connecting rod wrenches (for a three dip crankcase) on Epay and discovered they're all for a 5/8" nut!
Not a big deal as I can easily get a modern socket in there, but did Ford use a nut with a 5/8" outside diameter as opposed to modern practice?
It is my understanding that "back in the day" there were no Grade 5 or Grade 8 bolts or nuts available, so when a nut was needed for a high-stress situation, they used a thicker nut.
I hope the modern nuts you used are Grade 8.
You would have liked a Model A. They came with 21/32" nuts. That socket is hard to find.
I have a few of those. (Aus made)
I wondered what they were for.
That size socket used to be standard issue in a Craftsman mechanic's socket set, I think also a 25/32 was used?? (main bearing caps? Yes, one end was square, and that socket too, was standard issue, this clear up into the mid 1970s--that's when I bought my set that I still have)
George, Are you related to General McAuliffe?
