Topic: More water pump pulley marks 428 CJ

[Dave Stribling]

Found a square FoMoCo logo on a 428 CJ pulley off of an early 69 engine.  Haven't ever seen one with the square logo - saw one with the round before but most don't have either - just the part number.  This is the C80E-8509-A smaller pulley.

Have seen this before on pulleys. Apparently just another sub contractors method of marking them

I have a theory that the ink stamped pulleys were the multi sheave type where two or more pulleys were tack welded together to create a multi sheave and or one with different diameter sheaves. The engineering number was often times ink stamped onto the pulley instead of metal stamped on this type.  It makes it no fun to "ID" them without the convenient metal stamped number. Others may have a different theory. Bob

The two I have seen with the fomoco stamp were production line pieces, but I have some production line pieces without the logo too.  I also haven't personally seen a service piece with the stamp but there is a photo of one on Scott's site.  Different days, different vendors, moody stamp guy.....

If the pulleys are not metal stamped how would they be identified? I think ink stamping on assemblyline pullies would seem logical. Bob
