Super a flywheel

I am working on a super a and I need to know what the difference in heights should be on the machined surfaces of the flywheel?
I measure 1.2".

The clutch is only slightly worn, but even with adjustment clutch was not releasing properly. Pilot bushing was well worn.

I use pto on this tractor a lot for grain augers.

Thanks for any help. Nathan
 
The flywheel step should be 1.188" so 1.2" is only .012" , that much could be in your measuring instrument. Are you using a tape measure of an accurate depth gauge?

Corrected by adding a word that was in my head, but didn't make it to the screen.
 
Sounds like you have .012" of wear then. You'll need the surface machined and then the step taken down so you have your 1.188" difference.
If the flywheel surface is perfectly flat, I guess someone could have overlooked the step or machined it incorrectly the last time, therefore you might just need to machine the step. Although that shouldn't be the case.
 
.012 wear shouldn't keep a clutch from releasing but could make it slip easier. The sloppy pilot bearing is what makes it drag.
 
Took flywheel to Napa in bowling green, only to find out they no longer have a machine shop!! They suggest fleetpride down the street. Took it to them and in 15 minutes they had it done!!! Can't beat that. Although to the tune of $75.
