Can a Fidanza Flywheel be machined

[240sxOwner]

I though i read on their site that it could be machined for new surface....I have my kat now and i wanna throw in my fidanza while i am putting the motor in. Thanks for the help....

i thought for aluminum flywheels u just unscrew off the plate and buy a new one. i dont think u can machine them, at least u cant on my clutchmasters flywheel.

Flip it over.

you can get a new surface but i also i read that it can be resurfaced. You cannot flip it over....The mating surface is not aluminum, it is steel just like a stock flywheel

i machined mine during the last build. Works great.~Sam

Why couldn't you flip it over?

[sunnys14]

i dont think the friction plate will fit back on the flywheel if u just flip it over.

[chandler]

No you cant flip the friction surface over it has the screws countersunk in one side

[Chezedik]

Now that makes sense. It was just a thought. I just hate it when people tell me something can't be done, and won't say why. It usually turns out they said that because someone else told them, who happened to be full of ****. I still would think you could machine it though, so long as it was done carefully, and not too deeply.

And no sunny, I didn't mean flip the whole wheel, just the friction surface.

[sunnys14]

yes thats what i meant also. the friction surface wont fit on the flywheel if its flipped over like that.

what is everyones take on just throwing it in w/o resurfacing it...The clutch going on it has 4500 miles. Thoughts?

[eddiec]

use an abrasive disc on a air grinder. your really just wanting to break any glazing thats present.

[sunnys14]

its costs only 75 bucks for a new friction plate

[Chezedik]

First, I was just ****ing with you sunny, you have to admit it was a little funny. Second. Why not some low count sand paper and put some swirls in it. Also, you could use a dremel and a flapwheel.

[sunnys14]

u can do that too

[chandler]

has any on ever driven a car with a warped friction surface? man it blows chunks and chunks is a dog, anyways, you can machine the friction surface but only a little, then you have to get a new one, I got my flywheel used and man, did I have a time finding a surface, I remember nippon power or something like that, a guy named richard I think, hooked me up and it was about 75 shipped if I remember right

[240sxOwner]

I can get the replacement surface for cheap, but i need it today. I was just wondering how bad of an idea it would be to throw it in w/o machining. I really want my fidanza in there for the extra power, but i need it all done by tomorrow.

[:: orion ::]

Like some have suggested...use a light grit sandpaper, and use a swirling motion.

Cover the whole surface evenly...it's just to get the "glaze" off, to remove the shine.

That's ALL that's needed, unless the surface is badly heat scorched or something.

I've done this countless times, and never had one clutch issue.

I have only machined one flywheel in all of the clutches I have done, because it was covered in blue spots, and I was having it lightened anyway. You just break the glaze in a circular motion, and install it. Do it until you sweat and it isn't shiney, then you're done.

som like someone said, about 150 grit? What about using the same flywheel bolts? I have done 3 clutches and never bought new ones.....and never had an issue. Plus i have extra used bolts i can use...Thanks guys

[pregmantis]

do the sandpaper crosshatch/swirl thing it works fine. I usually reuse the flywheel bolts, works fine tooo. are we supposed change em? heh
