When I rebuilt mine I found that someone had put a big washer on the crankshaft behind the flywheel to space it out. For some reason the backside of the flywheel had been worn almost an 1/8 inch. So when I was rebuilding I put it back the same way I found it. Just cut 50 acres of hay with it, It did great.

Nice. A Standard chassis is way better too.

My 730D also had the flywheel hitting the case. I was missing the tin shield between the starter and the cover. When I got the shield, I couldn't install it because the flywheel was so close.
Was there a thrust washer on each side of the LH main bearing? The spec for end play is .005" to .010"; .012" is a little much but not too bad. My inner thrust washer was in place, but it came with a taper-lock flywheel that must have issues. I ended up putting a special made 3/16" thick washer to space out the flywheel and still give my proper end play. I ended up with .006". Remember that you still have to have a drive pin that engages the oil slinger notch. The machinist that made my washer also made me a special longer drive pin. Been working fine for a couple of years now.
