Finally another update.
If you don't care about the rest: I was able to rebuild the engine, reinstall it in the tractor, and get it running! I didn't take any pictures since they are the same as before. Just scroll up backwards to see previous pics.
This project isn't quite over yet, but should be only one more visit out to the land to get the tractor driving again.
I was recommended a machine shop in San Antonio, TX (E&E Machine and Parts) to have the crankshaft turned down. Kubota offers 2 oversized bearings. E&E were able to get the journals cleaned up and stay right at the +.2mm which was needed for the first oversized bearing. They had the job done in one day right at the end of October. I replaced the ruined bearing carrier and plasti-gauged the main bearings. I was at the upper end of the clearance specified in the manual, but still within tolerances so away I went.
Getting parts was the biggest slow-down. It took over a month for me to receive one order on the gaskets and bearings I ended up needing. In that order I had forgotten to put in the other half of the thrust bearings so that turned into yet another order which took even more time.
In the end, I got everything I needed to start putting the tractor back together. No pics again since everything looks the same.
I hauled the engine from where I rebuilt it back out to my land right after Christmas. We had the same fantastic neighbor (who helped us remove the engine) drive his Kubota over and pull it out of my truck. Getting it re-installed in the front half was tricky due to my poorly designed lifting bracket and the uneven terrain. We ended up rolling the front half of the tractor into the engine instead of vice-versa. That made it much easier and then used the working tractor to help roll the assembled front half back into position.
The rest isn't much but reversing the processes of before: The two halves came together and then I spent another day getting everything hooked back up (electrical, hoses, fuel lines) and then filling it with fluids.
First fire up took forever because I didn't sufficiently bleed the fuel lines, but it did eventually start. I still need to re-bleed the fuel system even after running it.
I have one error code (P0204, I hope the injector connector might not be pushed in all the way) and one coolant leak (off the thermostat housing, easy fix).
Due to the engine code, the coolant leak, and also not having quite enough coolant to fill the radiator I didn't actually bring the engine up to temp or drive the tractor.
Next time out I'll replace the leaky gasket and hopefully find/fix the error code. Once that's done I'll be able to drive it around. If that checks out then the hood and front end loader will go back on and this project will be done!
