Craig came over today to grab some parts and chat... we measured the failing clutch on my brat and came up with the following measurement of the "step" between the ring gear and the inner part (where the disk sits) of the flywheel.

We got a measurement of (more or less) 0.9000 Inches.

Does anyone know if its supposed to be this deep?

Or should it be more like .8500 or less? more??

We couldnt turn the clutch with the plastic alignment tool, but it sure as hell isnt grabbing against the torque of my webered EA81! My Chiltons manual doesnt have specs for flywheel depth.

And for those wondering... this is for a 4WD 82 brat. Its the tiny (commonly called 2WD clutch) NOT the big one that 83-84 Ea81's have.

Ya, everything EXCEPT the flywheel is new... and that has been resurfaced, but to what we belive to be the wrong specs.
