Back again, after pulling the pump and turning the rods 180 it still ran away. So I quit for the day. Sitting on the couch I got to thinking about what I had just done. I came to the conclusion that I had pulled the rods and put them back in just as I had removed them. So, I pulled the pump and...

Thanks, I gave it a try with no success, I am now thinking perhaps the wrong pump may have been installed. I can slow the engine down by restricting the fuel flow to the the injector pump. The owner removed the shut off solenoid and installed a block off plate. My son has a Kubota excavator...

Sorry for the delayed response as I have been under the weather. The pos update. Thanks for all the input. I don't know why I do and do not do somethings. I purchased a valve spring compressor, pulled the injectors, turned by hand the engine over and replaced the valve seals on each cylinder...

More info, thanks to all of you for your input. I have disconnected the injector lines and it will not run. Put them back on and it runs wide open. I removed the side throttle plate and can move the rack which makes no difference on it's running. The smoke is mostly light gray. I did not...

Thank you. You are correct as to your question about turning off the fuel. The owner has installed an electric fuel pump, which I did not turn on.

Not turbo. That is often a source of oil when the seal blows.

That is good, that is how we all learn.

Kubota D1105 3 cylinder in a lawn mower will run away if I let it. It cranks and runs without turning on the fuel. It has 350 lbs. per cylinder compression. Does anyone have a clue as to why this is happening? I lowered the engine oil to the add oil dot, did not help one bit. A little...

Not being the sharpest tool in the drawer it took me a little while to remember that the flywheel fits snugly on the crank and it's id checks 72.06mm. looks like I was sold the wrong seal.

Does anyone know the diameter of the crankshaft where the rear main seals on a d1105. I put a reground crankshaft in the block and the rear main seal has approximately a 1/16th of an inch gap between the crank and the seal. I sent the old crank back so I can not make a comparison. This engine...
