I finally found the specification for the step height on our flywheels.
.947"
For those that do not know the problem arises when you send your flywheel to a machine shop and they take the same amount from the center (friction surface) and the outside (pressure plate bolt surface). That is a problem because the friction surface wears as you use the clutch. So you end up with a disproportionate amount and a looser clutch.
Therefore next time you get your flywheel machined insist upon a 0.947" step!
And if we can save that so it is easily searchable for the world that would be amazing!
