Flywheel Minimum Thickness 69 RR is there one?

Would you know if there is a min thickness on the flywheel for a 69 Roadrunner?

Some cars are very specific about that but I never seen a specification in the 60's MoPar FSM. I bet it's listed in some literature somewhere and there must be a service limit.

Check with a machine shop that has been around. A lot of them have specifications in books on maximum machining tolerances. But, I don't know what it would take to thin one out to the point of non-use. I mean just as a guide, I'd be worried if the face to ring gear looked razor thin, or something to that extent.

There is no minimum. If you cannot get enough adjustment out of your linkage, you can get shims that go between the crank flange and the flywheel.

There has to be some kind of design criteria. It may very well be that you run out of adjustment, but a hell of a way to find out after you have everything back together.

The way my luck has been going that would be me. You don't learn if you don't do... Thanks for the feedback!

Most flywheels do not have a minimum spec that I have ever seen. They might have an obscure spec in some old engineering drawing, but I can not give a definitive answer. The ones that do are usually diesels (Cat, Cummings, Detroit, Dual-Mass, etc..). You only remove about 0.010" to clean up a flywheel, so, unless it is really messed up, it could take at lease 5 clutch jobs or more.
