No, it means you have a seal gone in the pump or maybe even just the lift pump is leaking back into the engine. I would start with the lift pump, cheaper and easier to repair.I have a grey market kubota and when i push a little hard it seams to get diesle in the crank oil ?

Ok, i am not sure what a lift pump is. I do have a shop manual for my b7100. I hope it will give me the info i need to fix it. Thank you very much for your help.
It is the mechanical or electric pump that supplies fuel to the main injection pump. Yours will be a mechanical one. Usually attached to the injection pump. Just follow the fuel lines.
Your welcome, we are all here to help (if we can). Keep us informed with your progress.
Well the pump was'nt the problem. but i did notice that the air vent screw was left wide open and was that way when i bought it. do you think this would contribute to the diesel getting into the oil? i shut it off and the tractor runs just fine. if not could you advise me on how to deal with the seal in the pump? that would be the injector pump, if i am correct.
PS.the air vent screw is located on the top of the injector pump.

I am surprised it ran hardly at all with the vent open. How do you know you are getting diesel in the oil.
When i check the oil the level is way up the dipsik. i fill it to the proper level and when i check after use the next day the level is way up again and the oil is thin and runny.
What els could it be?

So here i am at 2am, cant sleep. i'm now thinking is it possibly hydrolic fluid leaking in from the pump seal?.
Smell the oil- do you get a diesel odor?
You could also have an injector sticking- how does it run? If it runs smooth, that probably isn't it. But, you need to get this fixed- running it with diluted oil is going to kill the engine and the injection pump. And that is going to get ultra expensive.

Thats just it, i dont smell diesel so i am asuming it' s hydrolic fluid. i will remove the pump today for inspection. Thanks for all your help, this is a lot of fun and i hope i get corrected.

Hey, hodge, i have a b7100 hst as well and it has lots of hours but still runs fantastic. love that tractor as well but wish it had a loader insted of a snow
blade.
Well i fixed the problem. it was the hydrolic pump. have to replace it because it is wore out and putting pressure against the seal. the pump cost just under 500.00 bucks
I was able to use the pump from my b7100 hst. ordered another one for it. again thanks for all your help.
