Some background:When I first built my Maverick, I turned the OEM '87 302 flywheel and had it drilled for the old-style 3 finger pressure plate. I used a cheap reman clutch. In a few months, it was toast. So I replaced it with a new Borq Warner unit (same type). In about 6 months, I tore the center out of the clutch disc (left me in neutral and S.O.L.). So I went all out and bout a Ford Motorsport HD clutch kit and billet steel flywheel. (I converted to the newer diaphram-style clutch). It has been great, worked with a lot of abuse and launching for over 2 years now. My question: I have the tranny out, and the clutch looks good. But I ordered a new (same type) disc only, thinking I should replace the wear item since the clutch has seen so much abuse. What do I need to do? Should I turn the flywheel and pressure plate, or just the flywheel, or do i just need to scuff the new disc surface? Thanks ------------------

I never liked replacing just disc.The pressure plate does a lot of work and if not up to snuff will wear clutch disc out prematurly,and its just not worth pulling trans out again.Would resurface flywheel.

Well, I know that if the pressure plate wears out I have to replace it. But it is not worn out, and I am not going to at this time. Any other opinions? I think I'll probably resurface the flywheel. ------------------

Charlie,If the flywheel looks good then just replace the disc. Kinda like replacing brake shoes, if the drums look ok then just replace the shoes. But if there are cracks or very irregular surface(s) then have them turned. I read your post as a P.M., and if I were in the same situation I would just replace the disc. If it ain't broke..... don't fix it.  SteveW

I don't know? 
If the PP has already been through several thousand cycles, it would seem prudent to me to replace it as long as it is all apart already. I'd sure hate to have to do it again in another 6k miles. ------------------

I know. Honestly, I am broke. I cannot afford the extra $150 right now. Maybe I should have not even bought the disc only, but I already did. I am not buying the PP, I can't.Pulling the tranny on my car is as easy as pulling out the driveshaft, and it doesn't cost me a dime ------------------

If you are not going to replace the pp don't do anything to the rest of it since it has seated it self to what you already have. Right now you will be getting full contact on both sides of the clutch disc if you change the disc and and resurface the flywheel then the pp is worn for the other disc and might slip noticeably until it seats if you don' crystalize the disc. Put it back just like it was and save your money to buy a new pp and tb to go with the new disc.Rudy ------------------

Charlie,
Which FMS clutch set did you use..the A302 or C302??
Do you think I should use the stronger FMS C302 (Cobra) clutch set with my 331 stroker, 4 speed toploader, and 10.5" aftermarket ALUM/steel flywheel? I am already using a custom diaphram clutch setup with my old flywheel, but the clutch has been fried a few times and with the new 331 motor installation, I would like to put in all new clutch components. I considered the Dual Friction setup, but after seeing a few of their clutch systems fly apart at 6000 rpms, I think I'll stick with Ford.
