Flywheel question...

[Ieatcamaros]

I have seen a pressure plate cause a vibration before too. Did you get a new clutch kit? If everything was fine before the swap, it almost has to be the flywheel or the pressure plate. Even if the rubber on the harmonic balancer has deteriorated some, that will not throw the balance off. Just the timing marks. You might notice a slight vibration from this but I doubt it.

I got the Ford Racing Clutch kit new from Summitracing.com. Is there any way to find out if these parts are defective or not, with out buying new ones?
I think I'll try the balancer first (it's only $75 from Summit), but I'm gonna think about it over the Easter weekend, so post away.
I hate doing this guesswork.

did you try removing the fan and waterpump belt yet? I have had a similar problem in the past and the water pump bearing was going bad and was wobbling causing a serious vibration.

Yepp, I try'd that today same viration (note this is not a massive vobration just a little), but there was a little movement in the fan axle.

Yeah, pay someone to put it on a balancing machine. Seriously, I'd look at your flywheel. If your pressure plate is brand new and it fit the flywheel dowels good, then it is probably not the culprit. The reason I would suspect the flywheel is because everything was fine until this swap. I know this is a lot of work, but you could take your tranny out and put the automatic flywheel back on and put the bell housing from the t5 on and put the starter on. Then see if she vibrates. I have never put an automatic flywheel on with manual tranny bellhousing, I am assuming this will work ok. The only other way is to send your flywheel off to have it checked out. Since you are in Iceland, this may be more trouble than it seems to me. BTW, does the vibration intensify or dull throughout the rpm range or does it stay the same?

The AOD flexplate is bigger in diameter than the T-5 flywheel so thart won't work, allso I've sold the AOD.
And yes, it would be less expencive to buy another new flywheel than sending the old one to the US for a check out.
The vibration intencifies to 2000 rpm and stays the same from that throughtout. At idle I feel no vibration.
