Curious. Could benefit all of mankind.

Partsgroup dude told me folks modify the 1.6 fly to use with a twin plate clutch. I wanna know if it's possible or plausible.

I need the following dimensions:

crank surface to friction surface, +/-.100" is fine
bolt circle diameter to +/-.030"
outer diameter of friction surface to +/-.030
inner diameter of friction surface to +/-.030

thickness of the flywheel JUST outside the friction surface.. where you'd bolt a clutch to if it didn't have the threaded hole towers. rough dim is fine.

Thanks!

Matt

I don't own a ruler that accurate, but I'll do what I can if the trans gets dropped.

I think I still have my flywheel sitting in my garage. I will look for it this weekend. If I do, feel free to take it and measure what you need.

Would measurements from a non oem flywheel would suffice?

I guess it depends on what it is. Lets call it "yes if steel"

Yoram: I may take you up on that since you're local.

if anyone else gets it done first, that's cool too.


and I only found out about this like a few days ago!

I just took my old one out and put in a resurfaced one. If you have the measuring tools we can meet up and you can take what you need. I need to take it back to PBC soon so i can get my exchange $ back soon though

K, got some measurements for u, I was not exactly sure what you needed, but hope it helps.
158mm ID of friction surface
276mm OD of friction surface, however there is 117mm of usable material beyond that until the edge of the disc (not counting the teeth obviously) The pressure plate bolts are less than half of an inch inward of the edge of the flywheel. Also I dont have any way to really measure how thick the metal is at the friction surface
