Hey guys, quick question before I start tightening up the flywheel bolts. Does the surface of the flywheel where it touches the clutch has to be smooth/flashy/mirror finish or is it okay to be a little bit rough? The old flywheel I'm taking out has this mirror finish like the brake discs after they've been run for a while but the new one has a little rough finish like tiny streaks left behind. This is first time I'm doing a flywheel but something tells me that the flywheel is good like that. THe rougher the more friction. I'm sure it will wear out like the break discs after a while and become more glossy, etc. Just want someone with experience to confirm this.

P.S. Took out the tranny for the first time in a few hours. Wasn't tough. Shook it out and bench pressed it outta there. Piece of cake. We'll see how putting it back on will be.

Thanks guys!

If you are replacing the clutch I would have a machine shop resurface the flywheel ,so you dont get premature wear on the clutch due to an uneven surfaced flywheel. your prob. done by the time you see this!

i think the flywheel whould be smooth, a rough finish will wear on your clutch, bump for more info though

the old flywheel is really glossy/smooth.. the new one i got has a rougher directional cutting done on it... this is what i got: http://cgi.ebay.com/ebaymotors...ZWDVW

Btw, i think the new one will wear out to be gloss after a bit of warm up/use but i was just wondering if i have to have it gloss/mirror smooth before install or if i can just install it and wear it in... it'd think a slightly rougher surface would be better for more friction better grip for the clutch..

Here are a couple pictures.. let me know what you guys think about this





See where the clutch touches the flywheel surface there are those rough, directional, streaks going on.. I've seen brake rotors with similar finishes in the past and they get glossy after a bit of break in time. Is this normal for a flywheel? I'd like to know before I torque down the bolts and finish up with the clutch install.

That's how all resurfaced flywheels look. You're good to put the clutch on....Don't worry about it.

put it back together. that is what a new flywheel looks like. you used brake rotors as an example. when you buy new discs, they look similar. it is the finish that is left by the machining process.

you got your answer...

Yes that's normal... it's a fresh friction surface.

i know it's fresh but i was reading another thread on here that a directional surface like the one above is no good (usually resurfaced by a machine for brake rotors). the guy was saying the clutch will chatter if the flywheel has directional/rough surface... is that true? does an oem or napa or any major auto store flywheel have a similar surface finish?

thanks guys, much appreciated!

civic_driver

alright, thanks much guys... I guess it's ON now!

going back under the car.. ttyl
