Default flywheel resurfacing

i am going to be doing my clutch next weekend prob. i have a spec clutch kit. i have the pressure plate, clutch disk, to bearing and pilot bearing. the flywheel i have heard should be resurfaced. called advance auto and they said local parts store chains don't do it. where would i get it done at and how much am i looking at spending. and is it a must or does it depend on the condition of the flywheel?

You'll have to find a machine shop that works on motors. If there aren't any major flaws like scratches on the flywheel then forget it anyways. If you're old clutch started to tear into the flywheel and scarred the surface then get it resurfaced or buy a new one, but otherwise save your cash because you're not going to do anything otherwise. As soon as you put it all back together the flywheel will smooth out what little flaws it has if nothing major is wrong with it.

I hope you aren't saying to not resurface the flywheel? That would not be doing the job right.

Find an automotive machine shop. They will be able to do it, plus your rotors too when you need to do your brakes. And don't forget to resurface the pressure plate or replace it (better to replace that part).

I am, with my Focus and the Cobra we had spacing issues when the flywheel was resurfaced. This was done by Delk, a mustang shop, and I know they did not take that much off. There's no real need to resurface the flywheel if its not scarred, all its going to do is wear once the new clutch is in anyways.

He'd be better taking the money it'd take to get it resurfaced and just buy a Fidanza Alum. Flywheel. Took me $50 each for resurfacing and I could get a new one for $200 that would've been half the rotating mass.

The problem with not resurfacing a flywheel is the same like not resurfacing rotors. The old friction material, or glazing (depending how bad you are), is left on the flywheel. This doesn't let the new friction material break-in properly, thereby reducing the friction available. If one is going to be cheap, at least use some fine emery cloth to rough up the surface.

Now, when you had your spacing issue, was this with an Aluminum flywheel? If not, an iron/steel one should only cause a mild geometry issue with the pivot ball not being the .01" long enough. Resurfacing an Aluminum is a no-no as the inserts would be thinner than the flywheel, making the pressure plate ring travel further than it's designed to.

As for a six, it would be even more of a dog with an Aluminum flywheel. Steel or iron would be the best chose, depending on the budget. The price difference is small for iron (resurface should be $15-30 and a new iron flywheel around $50).

I don't think it was aluminum. It was the stock flywheel in my Cobra and the stock one in my SVT Focus, I think both are steel by factory. Looked like steel. The Cobra wasn't as bad, but the Focus was definitely not right after getting the flywheel resurfaced.

Both had aluminum flywheels when all was said and done. Sold the focus soon after so it didn't get much testing, but the Cobra has yet to make the whacking sound it was making. I just assumed that it was shaved too much and the throwout bearing was loose due to this.

I've done both. I have resurfaced them by hand with 320grit sand paper and or a sander real fast to rough them up for the new clutch. And I have also spend the $55 to have them resurfaced. Both cars worked great afterwards. Of course both were straight and not warped from over heating and didn't have hot spots.

Call every local shop around you and just ask them if they resurface or cut flywheels. I had to call 10 or so before I found 2 that did it near me.

yea, i am going to give it a good lookover to make sure it is not warped. if it is not scarred or warped i think i will just do it myself with some fine sandpaper. maybe a transmission shop? i don't have any machine shops close to me.

Hi Friend you first you must have to get the auto parts in the reasonable rate.
