Topic: Mystery ID plate on 59AB


swmddo    -- 02-26-2011 @ 5:13 AM
  I am in the middle of disassembling the block on my '48 59AB. There is a small plate riveted to the front of the block, right below where the intake manifold bolts on, about 1 1/2 " wide by 1/2 " high. The numbers on it read: RC 26
15567

Can't find any reference to that. Just curious....???
Thanks
Steve

  Just a guess here, but it could be an ID tag from a rebuild shop. Both Montgomery Ward and Sears once had engine rebuild/exchange programs.

  Ford used "authorized" rebuilders across the country. The tags were used to identify these engines for warranty purposes. The letters identify the plant, the numbers would be serial.

  Thanks! The engine looks so good, that it makes sense that it was rebuilt at one time.

  Underneath the 65 years of grunge, I found a similar plate. Turned out to be an engine rebuilder. When I opened the engine up the pistons were .020 over.

  Given that the newest flathead blocks are at least 58 years old, it is rare to find one that hasn't been rebuilt at least once, some OK, others a mess. Anyone planning to do a rebuild should take the stripped block to a good machine shop and have it tanked, Magnafluxed, and inspected for cylinder size and taper before proceeding. Today, it is rare to find any engine that doesn't have serious problems.
