After almost 2 years, it is time for me to bring this thread back. The k301, as worn as it is, has been doing alright in the 107 and I have been in no rush to do the work to the k241. The engine has been sitting on the workbench since I pulled it and I think it's finally time to start working on it. The engine is not the only piece to the puzzle as I believe it's time for a new driveshaft and couplings as well, but that may still be a ways out. The tractor is also going to need a pair of new front tires as well, as the originals are beyond their prime and have now begun to separate at the tread lines.
So tonight began disassembly and inspection. I apparently had the front bearing plate off at some point previously as the bolts were only finger tight. I was first able to confirm that the engine is indeed sleeved. There is a very clear ridge where the sleeve is compared to the block material. I could also see what was clearly a relatively new connecting rod.

Here's the top of the piston, maybe you can see the gap between it and the walls of the cylinder. I previously measured with a pair of pliers that the bore is .010" oversize and that this is a standard size piston incorrectly installed into it. Another thing, I noticed that the top of the piston does not actually reach the very top of the bore, as can be seen in the second picture. Is this how the engine is designed or is something else wrong here?

A couple other things I noticed, you can just see a little bit of the new style governor, another sign this engine was indeed rebuilt. Also, here's finally a picture of my infamous drill bit points plunger which I mentioned elsewhere in this thread, it is indeed one end of a drill bit with just a little bit of the spiral remaining. Interesting, yes, but it did work. Lastly just a quick shot of the internals after removing the oil sump.
