Ok, I've got to go back to the drawing board on this one. I think my assumption that it had spun rod bearings might have been incorrect
.
When I took the oil pan off I had seen that that area on the crank that surrounds the rod caps had bluing, which I was assuming was from heat? Didn't think this was normal so I assumed it was from possible spun rod bearings.
Second reason why I thought it had spun rod bearings was from the moment I dropped the pan. I had seen one piece of metal in the pan. It was magnetic (pictures attached). The piece of metal was somewhat smooth on one side and VERY rough on the other side which kind of perplexed me. It's almost like gritty/rust on one side. Don't know if it is bearing material.
A bit of information that I left out that I believe is important: When I bought this utility vehicle I had never heard the engine run. All I knew was that the engine would rotate 3/4 in either direction but would NOT do a full rotation. I had previously bought a kubota D1105T from a local mower shop so I could tinker with it. The D1105T that I bought from the mower shop had the same symptoms and upon tearing it down it had a broken rod bolt and the rod cap was 1/4 of the way off.
Fast forward to the motor im working on from this UTV. When I took the head off I noticed #1 piston was caked up with a 1/4" layer of what looked like seed. I guess when sitting a mouse had climbed through the intake and nested? That was apparently what was stopping the engine from full rotation. Kind of I guess hydro locking it. BUT this does not explain the metal I found in the pan.
I took all 3 rod caps off today and all 3 rod bearings and crank surface looked like new! So do I tear into it further to find where the metal came from? I cut into the oil filter and there was no metal to be found in the fins of the oil filter.
The picture of the head only shows some of the seed....I had already out of frustration cleaned the top of the piston and most of the head.
