how do I resurface a flywheel?

It's time for a new clutch, so I want to also resurface the flywheel. Now I've heard that the YJ and TJ FSM has a very clear and specific paragragh on why not to resurface their flywheels. Supposedly the face of the flywheel has a crown in it and the resurfacing will take it out. However, I have a CJ, does anyone know if I have to worry about this on my flywheel? If not, I'm sure that our machine shop here at work can do it for me. They just need to take a skim cut off of it, right? How about the finish on it?

Not sure on the how to, but I have seen in writeups on clutch replacement that NAPA stores will do a resurface for you. Don't know if that is anyhelp since you seem to have a way to do it, just thought I would chime in FWIW.

Re: how do I resurface a flywheel?

I took mine to a local machine shop and he had it ready for me in about about an hour. cost about $25. I figure it's one of those things I know nothing about, and might as well let some guy make his living off of.

yup, machine shop here too. i think i gave them 30.

or if you don't want to cut it, scuff it with a 3m pad on the die grinder. the idea is to get a fresh surface for the friction disk to grab.

Re: how do I resurface a flywheel?

You will have one of three stages of wear:

1) Slick, shiny, maybe a few dark patches.
2) Condition one, but more dark patches with tiny cracks in them.
3) Condition one, maybe with two thrown in, but grooves to boot.

If it's still in stage one, all you need to do is to work it over with coarse emery cloth or sand paper to break the glaze and freshen up the surface.

In condition two or three, you'll have to take it to an automotive machine shop where they can tell you if it's repairable or not. Small burned spots and checks are not necessarily a death warrant - usually they are only a few thousandths deep.

Re: how do I resurface a flywheel?

Well mine is definetly in condition one from above, except I do have some chatter when I let the clutch out. I did talk to the guys here at work and they don't really have a machine that can do it, so everyone I talked to recommended the same place to go. They want $40 to do it. Sounds a little high from what you guys paid.

For what it's worth, I think I paid $40 last time I had mine done.
