Quite the common problem that stems from the high compression engine stopping in one of four spots when turned off. These four spots show excess wear on the few teeth of the ring gear where the starter hits it. Usually there are five or six teeth that show wear, chipping, grinding, etc., marks.
The correction is to remove the transmission, just back far enough to get a breaker bar/long handled wrench in there to remove the flexplate to crankshaft bolts. Replace the flexplate, loc-tite blue on the bolts.
I'd replace the starter drive at the same time as those teeth will probably show some wear, chipping as well. Use a good quality starter drive. I buy nothing but AC Delco. Be sure the starter bolts are the correct size for the diesel starter (not the same as a gas engine bolt). Get them snug and install the nose brace on the front of the starter that bolts to the block. It's an absolute must-have item unless you want broken starter bolts. If the brace isn't there, buy, beg, borrow or fabricate one!
I used the word milling because that is how it was described in a GM manual I had back in the day. Grinding, milling, and just messing things up. And i borrowed this paragraph. I don't care if they are ACDelco or not. I have seen ACDelco come from the same Chinese village the Chinese junk comes from only in a package that is marked differently.
