A buddy of mine and I have a couple of aluminum flywheels that we picked up a few years ago. We can not figure out what they fit. We took them to a local crankshaft grinding shop and tried to fit them on every crank flange in the place. No luck. Does anyone know of a chart, web site or ....????.... that contains dimensional data for flywheel/crankshaft bolt patterns? His flywheel is in absolutely perfect condition. It's a Schiefer with a #501 on the backside. The center hole measures 3.125" and the bolt circle is 4.0" diameter. It has a 6 bolt hole pattern. Each hole is 7/16". Less the ring, the outside dia. is 13 7/8" and it uses an 11" clutch. A rare Auburn pressure plate is presently on it. I need to measure my flywheel, and it doesn't have any ID marks. I have a mid-70's Schiefer/Hurst catalog and his part# is not listed. There's no dimensional info except clutch size and overall outside diameter. I think his flywheel pre-dates Schiefer's acquisition by Hurst Performance Inc. THANKS
no ring gear on it I'm assuming? I'll dig around in my stack(s) here in a bit when I go out to the garage.
is that how many teeth it's got? also, the six holes, are they spaced equally or like ply/dodg/desoto's 6 bolt pattern?
how much are Schiefer aluminum flywheels goin for now? i have a perfect one for a 331 354 392 hemi. has a good clutch surface on it.
So, I guess the jury came in with a verdict. The #501 is a '54-'56 Olds????? Please verify that's correct. I got lost on some of the posts. Thanks for the help .
Is there a chart out that would list the common flange dimensions? I have several assorted CAE Crank flanges for a sprint car and dont know what they fit, I do know that a SBC flange is 6 bolts on a 3.580 center line. Thanks for your help
