Iv checked the archives and it seems when people replace their flywheels they have to move the flywheel weights from the old flywheel to the new flywheel and in the same position as the old flywheel.

My question is, what if you don’t have a flywheel to start with?
When I perform the auto to 6-speed conversion Im going to need a flywheel, but what about the weights? Can I just take my new flywheel to the machine shop and have them neutral balance it?

Don’t tell me the whole engine has to come out to have the entire rotating mass balanced.

Iv read about people in the archives performing this conversion but never found much info about what they did with the flywheel situation.

If it is a stock and unmodified engine, you can simply put in a stock one with the weight in the stock location. I think the weight is in the same place on all of them. Unless your engine is neutral balanced internally, you can not simply neutral balance the flywheel.

No Go

If you are speaking of the small fine tuning weights then I don't think they do much unless the engine was significantly out of whack.

The single large weight that acts as a 'counterbalance' should indeed be in the same position on all flywheels/flexplates.

I left all the fine tuning weights off my flywheel when I switched over from the LT1 Camaro flywheel as the holes were not similar to the ZF flywheel I was replacing. I've had the clutch on the car for ~14,000 miles with no ill effects.

I'd take both the original flexplate and the new flywheel to a good machine shop to have them "match balance" them.

If your car is going to be babied (kept under 4000rpms) then you'll probably be semi okay. Ever notice how identically prepared engines don't produce the same results? Keyword here is BALANCE. If you're lucky, okay, but I have to be good cause I'm sure not lucky as Murphy's Law always bites my AZZ. So, I'd take the rotating mass to a good engine balancer and go with an internal balancing arrangement. That way you can neutral balance your flywheel. But that's me.

Thanx for the help, a lot of good info here. :yesnod: :cheers:

:iagree: with Strick. Factory balance is "close or ballpark" average for all rotating assemblies. It needs the extra weight on flywheel or flexplate. The weight on both is in the same location. If "close" or "average" is OK with you, you will be fien with a factory weighted flywheel. OTOH, I went to full i9nternal balance & a neutral balance flywheel. Good luck. :flag
