I did a condition inspection on a 6-A that had the flywheel mounted one hole off (with constant speed). Rather than pull it off and mount it right, whoever did it just used a felt tip pen to place new timing marks.....ya sure do find a lot of strange things.:rolleyes:

This would allow the flywheel to be installed in any configuration. I would suggest confirming any flywheel installation on an engine new to you.

I don't think so, at least not on my O-360's

The hole in the crank flange is 0.031 larger diameter. The non-index bushing would not be a friction fit. See link in post #8.

However, with a big enough hammer I'm sure someone could make the flywheel fit in any orientation. :D

Good to know. I thought it was a stepped bushing with the same size hole in the flange.
