Thanks Ted for the tip on re-clocking the ring 45*.  I will certainly check the wear patterns in the future.

Thanx for the replies, it's just a cleanup and check. I'm at .20 also so it'll be just a true surface dressing. Gary

I’ll add that when reinstalling the starter ring gear back on the flywheel and turned over, re-clock it 45° from where it was so that the starter drive is meshing in a new area.  If you’ll observe any V8 flywheel ring gear, they always wear at the 90° intervals.  Just re-clock the flywheel so it falls between those original wear spots.

While you are at it, heat the starter ring with a torch (hot, but not red hot) .  A few hits with a hammer and a large drift punch will pop it right off (it comes off towards the clutch surface).  Heat it up again and Turn the ring around to get a fresh set of teeth for the starter to engage with.  With the ring off, the flywheel doesn't act as a heat sink and the ring grows bigger and it will most likely fall on.  It is not difficult at all.  When it cools, it contracts and again becomes the factory tight fit.  After Tim resurfaces the flywheels, I turn all the ring gears around before I put them up for sale.

Are you just cleaning it up or trying to lighten it?  You certainly don't want to cut down to the ring gear.  I just messured a couple out in the garage and got .200" step to the ring gear, I would think you could safely go another .050" from that maybe even to 1/8".  I don't have any specs, that is just what sounds good to me.

I'm going to have my 55, 272 10 inch flywheel machined, is there a thickness limit to be worried about?  Gary
