I suspect that "u" is short for USA and nothing is short for european? Just a WAG (wild guess), but sometimes you drop a last letter in the
number and all of a sudden it shows up and it's in stock. Otherwise they can't find it and it's endless arguments about updated part numbers in the far distant past and the counter guy isn't having any of it today or you too for that matter. This goes back to the letter series and only if I remember correctly. I came back a week later, dropped the R like I wanted the first guy to do and walked out with the parts. Only cost me a week and the extra 90 mile round trip, plus the very deere price for the parts.
I think I'm seeing a four ring piston with only 2 compression rings and an oil ring, is that second ring groove not machined properly enough to accept the second ring? And they just left it out? And it's always been this way? The bottom of the second groove is not finished so the assembler just left it out is my wondering at the moment.
I would opt for four new cylinder assemblies and I would bump the pistons out far enough to verify it has four rings. You'll have to borrow a decent ring compressor to get them back in there without breaking rings as it's important and critical. It can be done without, but I would never risk it. And a quality head job, Mother Deere might be the best bargain in the long run for that part. This one sounds like a genuine keeper, I wouldn't go cheapest on it. But with your minimal wear and if you could find someone to put a high quality hone with crosshatch in the cylinders you have, you might be able to get away with new sealing 0-rings, a set of piston rings and maybe one piston? A proper machinist needs to be consulted up close and personal with your engine at a minimum.
The old injector came apart and got spit out the exhaust valve by that single gouge dead center on that piston, very lucky it didn't beat that piston to death in there. That could have washed down that cylinder and without a decent cross hatch, the rings aren't going to seat until it gets pulled long and very hard. That's required for a decent compression test and did you happen to oil the cylinder to test for valve VS rings compression test like they did in the old days. If you suddenly have compression back then it's the rings and not the valves with an added couple of squirts of oil in there. The oil should probably be shot into that intake runner as using the injector hole is just going fill the space in the center of the piston and not get on the cylinder walls in this particular case.
