4th Gen Fidanza Flywheel not fitting on Crank Shaft

OC_Nooby · 08-05-2009, 07:23 PM

Hey

I ordered a fidanza flywheel (12lbs) and clutch from ebay. The flywheel weighs 12 pounds as stated and the clutch checks out. Now when I went to go put it on the flywheel does not fit on the crankshaft as the center hole is to small. My brother says the flywheel is a knock off. Is there any way of figuring if its a true fidanza flywheel? It does have some sort of ID scratched into the flywheel but thats it.

Any help would be appreciated. The flywheel is going to a machine shop tomorrow to have it enlarged, of course the original flywheel is going with it for proper measurement.

Thanks

I've never heard of this, but if your having it machined then I guess it wont matter. Maybe someone will chime in that has had the same problem.

I have installed a few Fidanza's and they have always been really snug. The one I just installed took a few minutes of light sanding and testing to get it to fit right. Never required any machining though.

was there any labels or marking to show that its a fidanza flywheel?

The fidanza I installed was snug as well, I just put in 6 flywheel bolts and tightened them evenly with not much effort till it pulled flush with the crank. Then removed the bolts and re-installed with loctite and torqued to 69 ft-lbs, have 600 miles on it now no vibration.

what's the weight difference on the fidanza? I ma very interested in the flywheel but Aasco said the stock flywheel was like 15 pounds? and that 5 pounds would be better? im looknig for about half of the stock weight. can anyone verify what that might be?

i have a 4th gen
