This flywheel is counter balanced. The number on the flywheel is 30-22023. Hoping I can use it on my buick nailhead I appreciate any help you can give.chris Sent from my SM-G960W using The H.A.M.B. mobile app
Chris...look on the side of the ring gear and see what the tooth count is..I'll look it up when you report back..
Are all things same,bolt pat,ring off set,and If your engine has a factory steel or cast flywheel,you can kind of check balance, with a bubble wheel balancer= must put both wheel together lined up,but with one wheel{ 180* to other wheel=if new wheel has same "Off/counter balance as old wheel" then they will set fairly level on wheel balancer,if they lay off to one side"no,you need new matched to old. The one being 180* is so offset balance is opposite each other for a match..
In the meantime...this is the resource I go to first to identify old flywheels...it is from my 1968 Bell Auto Parts catalog..
Tooth count narrows your search big time...if there happens to be a couple with the same count..then you can narrow it down further with the crank bolt pattern..
Old cast flywheels have been known to come apart and are outlawed by racing organizations. I’m not saying not to use it; but realize what you have....
Alum flywheel is one of those things too use were needed,and pass up on if not ,vs a steel flywheel. Thing is if its a vary lite car/say under 2500 lbs. and your really looking for good drag race speed,it is great, But in a car of 3000+,using alum wheel is going to slow you down. Bigger cars need the steel to get it going start an each shift. I'm only talking ,as have seen some use things,just thinking it was sexy. But we can't see a flywheel. I talked about balance a few post above.
Sorry just found this post again.tooth count is153.chris Sent from my SM-G960W using The H.A.M.B. mobile app
"Old cast flywheels have been known to come apart and are outlawed by racing organizations. I’m not saying not to use it; but realize what you have...." Aren't these flywheels forged?
Also aluminum flywheel are for high revving engines so I would be careful using it just a word of advice.
As far as 153 tooth flywheels in my catalog. ...looks like there are two. Chevy with 10.5 clutch..or big block Ford. The Chevy has the extra hole in the pattern like your flywheel. Measure the iron insert..if measures slightly less than 10.5"..its for Chevy.
The Schiefer / Alcoa flywheel in the first pictures sure looks to have forging metal flow lines, the Weber catalog says they are forged and "Guaranteed Blow-Up Proof". Are Schiefer and Weber flywheels one and the same thing?
