So here is the situation. My setup was an act 2600 and a street disk that had about 20k on it. I swapped to awd couple years ago and got a used act flywheel resurfaced and put my street disk and pp back on it and its worked fine since then. I have since switched to e85 and the clutch started slipping at about 25-26 psi. So I got a new southbend kevlar disk and put it in with a new oem tob.

Since the tranny was out last, the car has maybe about 3k on it. The flywheel and pp looked to be in pretty good condition so I left them alone other than lightly sanding them by hand. No hot spots or anything like that. Now since I put the clutch disk in the car wont shift into a gear when the car is on. It will go into gear when the car is off, and I can start it in first and let off the clutch and it will act normal but it will not go into gear when the car is on.
I have searched around and it seems it has to be an issue with the clutch assembly somehow. The master cylinder has a couple hundred miles on it, and the slave is recently rebuilt as well. It is bled properly and I have adjusted the master every which way it can be with no change in result.

So now my question is how many times can an act flywheel be resurfaced? Any other suggestions to the problem are welcome as well. Thanks, Chris

I've never had to do it more than twice on any of my 6 dizzums.. So 2 for sure

i would say only 2 to be on the safe side. im sure you can find the minimum thickness spec by contacting ACT. its like a brake rotor and needs to be at least thick enough to disapate heat and still not vibrate.

It really depends on how bad the flywheel surface was damaged/warped the first time, and how much the machinist had to take off.

It's such a variable answer, because it really varies from flywheel to flywheel, and machinist to machinist.

When you machine the flywheel and step it correctly, the clutch geometry moves by however much material was removed from the mating surface between the PP and flywheel. Hence shimming the pivot ball.
