So I'm in the middle of a clutch rebuild and I'm wondering if anyone knows the factory recommended step height for the flywheel. This would be the distance between the friction surface that the clutch rubs on to the surface that the pressure plate assembly bolts to.

The machine shop that I'm going to have resurface the flywheel said that they're just going to take the same amount off of the friction surface as they'll take off of the mounting surface but is there a specification of how far apart they need to be or does the clutch even wear the flywheel enough to affect this distance?

hey, I just did my clutch and had my flywheel machined and the guy at the machine shop looked up the distance and machined it RIGHT, my clutch from the previous owner wasn't machined at all so it was 5/16th of an inch off and made the clutch slip before it was worn out.

now in answer to your post I don't know what the distance is supposed to be I just know it's really critical! obviously. and the clutch disc does wear some of the metal off of the friction surface so it's gonna be off a bit, like mine was 5/16th of an inch. when it's done right it makes for one smooth clutch though lemme tell ya!

You might google it? but you definitely want to have them machine the mounting posts down too!

I can't answer your question, but have you considered having the flywheel lightened? The shop I used lightened and resurfaced it for $65. They took off nearly two pounds off the outer lip. It was 19 and now 17 pounds, that's nearly 10% lighter. I believe it accelerates out of turns better.

I didn't think about getting it lightened, next time I guess.

The shop that I brought it to looked up what the distance should be. The guy said that they had done several escorts in the past and it showed because they did an awesome job.

iirc it is 20mm or .787"

Only have it lightened if you want to spin quicker. Heavier flywheels get better gas mileage. Up to you what you want there.

I made 8 mpg at a race one time.
