At this point I would ask what has been found for consistancy in finnished dimentions of PRESSED parts,,,I recall discussions on this and as I recall,,,parts of that era are NOT always interchangable,,, I remember when I got a new timing gear from Cefreed, at Bugatti parts,,,it was .250 too wide on the hub,,I questioned it and was told that the engine was no doubt worn,,so there was extra dimention to allow it to be machined to a clearence of .004 ,, Oh yes it was the famous FIBER helical gear , w/ shaft below the flywheel at the rear,,,In case any of you get to work on one of these,,there are 2 starter teeth that are ground short, so it will come out ,,,I now have a vvverry small bald spot,, tear my hair out ,, haha,, I have seen funny crank parts and have wonderd if there was a mismatch of fits by unqualified mechanics,, Many years ago I was to assemble a motorcycle crank,,,,and ended up with 12 flywheels before I got a pair with the same stroke,,the owner was planing to assemble what he had,,never realizing the f/wheels stroke was .030 different,,this was a 1936 machine,,then the fun began,,,Can we share input on this,???,,,Ben
