WR fly wheel on AAN

[goodall]

Just to ask, pretty sure will work, but is the reference pin on a WR flywheel from a Ur quattro in the same place as for an AAN as I'm about to fit said together for my Ur quattro

Thanks, Stephen

Yes that is exactly what you need if you going to retain the original Typ85 gearbox.
You will also need to purchase a new rear crank spigot bearing to insert into the AAN crank

Yep using the original 016 from her

Need check the part number for the bearing, shouldn't be killer of audi

On a side note, I notice that the ring on the front the fly wheel could be removed, quick calculation shows be about 2.5 kg and on the outside so removing it would reduce the moment of inertia greatly. And then using a S6 or 7A cover plate, what I have to hand, and the ur clutch disc should work nicely...
