I have no idea if the crankshaft hole varies from one 1920s crankshaft to another, since I have not measured any other than the one that I am working on.

However, this whole discussion has come full circle.

I started this thread because the bushing that I bought from one of the Chevy 4 cylinder vendors was not a press fit. It is .8155" in diameter, whereas the hole in the crankshaft varies from .818" to .8245".

Based on Jerry's info (that Loctite green will handle up to .015" of slop), I can:

1. Use the bushing that I bought from the vendor as is. nanner

2. Using Jerry's suggestion to let the transmission input shaft do the aligning and the Loctite green to 'fill in the gaps', the bushing will be perfectly aligned with the flywheel, even though the crankshaft hole is slightly egg shaped.

Thanks to all for a great conversation that arrived at a very doable solution!!

Happy happy! Dean
