Should I get this flywheel and pressure plate resurfaced?
Is this spotting normal? My bellhousing was VERY dirty and I'm guessing these spots were from burned off oil. The clutch was holding fine before I took it off. This is a FM flywheel and an ACT extreme pp and extreme organic disc (with 30K of wear).

Looks like very little wear for 30k miles and piles of launches. http://mekalummezar.com/carpics2/disc.jpg http://mekalummezar.com/carpics2/disc1.jpg |
I would. But thats just me.
|
I suggest cleaning the flywheel with a scotchbrite and brake clean or something similar to get whatever is discoloring it off. Otherwise that is a ton of really awkward abnormal hotspots and I would resurface it for sure.
|
Scotchbrite them bitches. Those don't look like seriously bad hot spots, if they were they would be black/blue/purple like a rainbow. Disk looks good too.

What brand disk?
|
Looks like the ACT disc that comes with the HD or XT street disc package.
I'd see if FM has a replacement friction surface for the flywheel and simply scotch-brite the PP> |
yeah you cant resurface that flywheel, and i've yet to find a machinist that will resurface a pressure plate. so its either new friction surface and new pressure plate, or do your best to clean it up yourself.
|
yes you should resurface it.
|
get a new friction plate.
A flyin miata flywheel = fidanzda IIRC |
Resurface the flywheel, or use emory cloth on both of them.
I made the mistake of not doing one of those on my DSM and it suffered from horrible clutch shudder. |

I would resurface it. Some of that kind of marking is normal, but that much is abnormal. If you decide not to resurface it, at the very least scuff it by hand with some fine grit paper in small circular motions. But I say resurface. Edit:Remembered it was an aluminum flywheel. If you remove the friction face from the flywheel, the machine shop can put it on their giant belt sander for a second and freshen/true it right up easy. PP also. |
Miata's are really sensitive to clutch stack height. I think that if you resurface the flywheel and pp and reuse that disc, you're going to either have a pedal that engages WAY at the top or not at all.

.015 on both the fw and pp, and .050 total wear on the disc is 1/3 the total thickness of the disc... That doesn't include the 30k miles of wear on the fw and pp.
|
Resurface!!! I made the mistake of not doing it, just cleaning and scotchbrite, when I put in a new clutch and my car jerked all thye time. had to put in another clutch.
|
OK I found out that the old FM flywheel can have a replacement surface installed. I'm going to take it to a shop today to see if they can resurface it first though.
|
i told you this already!
|
Riiiiight :). Ty :>.
Fyi for anyone else who needs a new surface for their old purple fm flywheel, you can get one from fidanza but you need to count up the number of plate bolts firt. |

I bet everyone who had problems when the didn't resurface also put in a new disc. Frank |
