The engine struggled like this before I did anything to it. Only thing that was done was hone and rings basically. I am not convinced the starter is not hosed. A friend had this thing before and likely cranked on that starter for an hour at a time. What I suspect is shorted windings that I...

Per my other posts, I just got a D950 patched up and running. However, it is obvious to me that it cranks over slower than normal. Even when jumping off a running vehicle and confirming that I am getting 11.3V during cranking at the starter (which is roughly normal), it just does not crank...

Just my take after being in the engine. The liners are to provide a harder, more durable bore than cast iron can provide. Offering .5mm pistons seems pretty stupid IMO, and not a wise play. the bores are hard, and trying to run a boring setup in those bores is asking for problems. And honing...

I've never bought Bota parts so couldn't tell ya but $100 for a set of 3 rings for a piston? $300 just to put rings in it? A normally sane price is probably $25-35.

Looking to see if anyone here has located places in the USA to get parts? I have priced some factory parts and I might as well go find another engine before paying these stupid prices! I primarily just want piston rings and head gasket, but I might settle for a piston kit and top end kit...

What was the failure mode? Are the sleeves fully supported at the bottom or hang free? When building race engines, I used to have issue getting people to tear down and do pistons. Excessive piston slap could cause some unneeded drama. I am not really for boring, but i'd probably consider...

Dealing with issues with this engine in a piece of equipment. Others gave up on it so I took over. I am not a rookie with engines but never built a Kubota. I just went through the head after someone else paid to have it "rebuilt". I could valve springs that were not down in their homes, and...
