Desperately need help with flywheel resurfacing.
Guys,
I have an '87 TII. I am in the middle of changing the clutch. I'm using all stock components. The clutch was slipping and shows signs of burning but the disc is not worn out. Here is my problem: I took the flywheel to a machine shop. They can not find any spec. on the thickness of the flywheel or what the "step" should be at the mating surface. They believe that the flywheel has been turned before and that the step has been almost milled off. They only have a spec. sheet that goes through the '84 RX7. Can anyone give me a spec. on the thickness of the stock flywheel or the height of the stepped surface (where the clutch contacts it)? I'm getting desperate here...no one seem to know. Todd |
i am no expert on this subject but might be able to help a little, i think that sometimes its hard to find a shop that actually cuts flywheels anymore today
but i can say that if the guys at the shop told you that then they probably have an idea of what they are talkin about and your flywheel might be worn out. they can probably just about eyeball any flywheel and tell you about it. kinda like a good brake man with rotors. it would probably be safest to get a new one then to risk the same problem again. im taking a guess that it showed signs of burning up b/c the flywheel might not have been able to absorb heat like a new one if you havnt already tried calling other places, a good mazda shop would probably be able to tell you the specs sorry i couldnt be more help but it appears that no one else knows either |
I just took a look though the 87/88 FSM and only found info about the runout (warpage) max 0.008" allowed if more grind a max of 0.02" off.

Yeah....I found the same info in my FSM. Honestly I can't believe that there is no spec. for the thickness of the flywheel. How is one to know if it has been "cut" in the past???

Well, if you can swing the $300 for a new lightened flywheel, at least you will get a nice horsepower gain for your troubles.

Stop the madness!!!!!!
There is no step on the flywheel.
Snatch your flywheel from these boinger disciples and get a few sheets of the green grinding paper from a auto parts shop in the auto body section, or a hardware store. Put it on a orbital sander. Cut the glaze on the flywheel with several peices of grinding grit until the flywheel is scratched silver all over. Re-assemble your car with a new clutch from www.clutchmasters.com also replace the throwout bearing. Put it back together and enjoy you new clutch.... (It will seem loose and soft, but that normal) |
