Need Schiefer Flywheel Identification

I bought a nice Schiefer aluminum flywheel. I thought it was a Chevy. Ain't so. I need help to ID this thing before I dispose of it.

Crankshaft bolt pattern is 6 bolts on a 3.25" bolt circle. Center hole is 2.080". 168 teeth on ring gear. Bronze clutch disc contact surface is 10 1/8" dia., so I guess that means it takes a 10" clutch disc. Overall wheel diameter, less ring gear, is 13 7/16". In cluding ring gear it's about 14 3/16" dia.

HELP!!!

 

Most of them have the part number stamped under one of the SCHIEFER embosed names on the back.

I have a Pontiac one #611

 

some of the chevy 292 engines used a 3 dowel flywheel similar to the 235,but different. maybe that's what it is? diameter and tooth count matches. bolt holes would be 1/2" instead of 7/16" that other chevys use.

 

Post a part number if you can find one and I'll check my old Moon catalogs.

 

go here and scroll down to V2018 and see if that's it

different clutch size, which is probably to be expected on a performace flywheel replacing a truck flywheel

 

What exactly makes you say it's not Chevy?

 

There is NO part# on the flywheel. Only a PAT #, and we know that won't do us any good.

Thanks for the offer to help.

 

This makes sense. I'll check the crank flange on a Chevy 230-292 six.

Now that I think about it. I asked the seller if it was a Chevy. He said yes, but I never asked specifically if it was a V8.

That web site catalog has some great reference information. I can get close to the flywheel application using the ring gear dimensions.

Thanks for the help.

 

Well, it wouldn't fit on a 327 V8 Chevy crank flange.

But, as Squirrel mentioned, it might be an inline 6 Chevy flywheel.

 

the 292 was the only one of the late model 6s that used the 3 dowel setup. not the 230/250.

and from that list I linked to, it's 67-up that use them. I wasn't sure about the year break, but that make sense. I did mess with a couple 292s several years ago, one a 66, one a 68, one of them was normal Chevy and the other had 3 dowels, now that I think of it the 68 was the three dowel one.

 

Squirrel,

Great tech info. Appreciate the help x 2 !!!!!!

But ..... will it work on the earlier crank and ya' just use one of the 3 dowel holes? Or am I out to lunch with that thinking?

 

as I said the bolt holes are 1/2" instead of 7/16" that all the other chevy cranks used, so I would not try it.

sell it as a 67-up 292 flywheel....

 

i have 4 schiefer fly wheels i am trying to id . 30-30067, 30-30064 ,30-30075 ,30-40064 wiuld very much like to know what they fit if any one can do this. thanks .mike hilton

 

I have a chance to buy a couple of NOS Schiefer Flywheels in the original boxes but the description is partially obscured by boxing tape. They show to be for 54-57 Ford.
One has Model # F454.
Other has Model #4454.
Is one for F-100 and the other P***enger?
See attached pics.
Thanks for any help!

 

Count the starter teeth would help

 

If you look carefully at the 3 dowel holes they are not equidistant to the mounting holes. My GMC Schiefer has been drilled for three 3/8” dowels.

The GMC also only fits one way. The 6 holes are not equidistant.

 

What does the back of the flywheel look like? Is it the same all over, or is there an area that has extra weight for a "Detroit balance" ?
55-63 6yl 168 teeth 14.096 gear OD Zero Balance
55-76 V8 168 teeth 14.096 Zero except 400 & 454
70-76 V8 168 14.096 Detroit 400 & 454
From a chart I have, I don't see anything else with 168 teeth

 

Here's pics of both sides of the #F454. I verified the application of #4454 as 54-57 Ford-Merc 292, 312 in an old catalog and bought it. The F454 may be the same but I can't find that Model # in any catalog I've seen.

 

Oops! Forgot to attach pics of #F454

 

Here's a pic of the 1965 Schiefer Catalog I found.
