Well I got the parts for my tractor and am now in the process of reassembly. Decided to face the flywheel as after inspection it showed to be uneven by .003, book says .0039 is max allowable but the surface finish was not acceptable for me. Couple pics.

Next is a shot of the setup

I just barely fit on my lathe so I had to use an extended tool and crank my compound as far as it would go. Got an idea for long toolholder that would replace my QCTH for doing such jobs in the future.

Before and after applying some John Deere green.

Today was too damn hot and humid to work on it so maybe sometime during the next week.

Stange setup those JD's. That looks like a recess on the flywheel. Just finished my 53 Ford which included the flywheel machining. Noticed also there is no ring gear for the starter? Are you replacing the ring gear?

You can see the ring gear in this pic.

Yes the clutch surface is recessed, don't know why except to say that it means there is more mass, thus heavier.

The dish is to minimize warping,same thing is seen in heavy trucks or basically anytime a clutch is apt to be slipped or loaded hard as part of normal operation.
It can also be used to provide for a second clutch/pressure plate(pto clutch).
