Do I need to resurface my Flywheel?

[slider2828]

Hey Guys:

The flywheel is like 6 months old. It is a fidanza flywheel and it maybe has like 6k miles on it. How do I check if I need to replace the face of the flywheel or not?

Has anyone ever replaced the face on it? If so, was it hard and were there any instructions included in the face?

Hot spots, cracks or warpage. If all of that is ok, then its fine. With 6k miles on it, unless you were slipping the clutch a lot it should be fine.

shouldn't the flywheel be resurfaced every time a new clutch is put in?


There are hotspots on my TODA flywheel. Is that a negative thing?

I suggest resurfacing, do it once the right way, instead of doing it wrong once only to have to do it all over.

Hot spots usually means you have dropped the clutch more than slipping the clutch if iirc, its just normal but does mean you do need to get the flywheel resurfaced.

There most likely isn't a need to resurface it. Resurfacing is usually done because a flywheel wears much like a brake rotor. Over time grooves develop in the flywheel and the surface needs to machined so its all even. It also removes any warping. This allows maximum surface area contact with the friction disk, and a mating surface for the clutch to break in on.

Check the flywheel for warping with a straight edge and some feeler gauges. Then inspect the surface for gouging, grooves, and cracks. If thats all fine, take some fine grit sand paper and scuff the flywheel in a non-dirrectional pattern, then wash it with soap and water - not brake cleaner - soap and water!

Remember to replace the pilot bushing. Don't cheap out on a $1.50 piece of brass.

Hot spots are usually caused by 'dropping' the clutch. The discolored areas have been overheated and their chemical and physical properties have changed. The discolored metal now has a different friction coefficient than the rest of the flywheel. I would get the flywheel resurfaced .002" - .008" or whatever it takes to cut off the surface layer. If the hot spots are still there after surfacing, just live with them.

Any time you replace the clutch, you should resurface your flywheel. In the case of the fidanza, just buy a new face - they're like 70 bucks. I replaced mine and had no problems, it's pretty straightforward. The only problem I had was figuring out if I had 20 or 18 screw holes, because my transmission was still in the car. Turns out you have to buy both, so that problem was solved. Do you have 18 or 20? I have an extra 20 if you need it.

^ yep

you don't resurface a fidanza... you just buy a new contact plate and slap it on.

Are there any torque specs to the screws and how many screws do I need?

Go DL the FSM and check, im sure its in there.

Just e-mail Fidanza.
