hydraulic fluid in oil?

[bob sullivant]

I have a b7200 Kubota HST that is leaking more and more hydrauliic fluid and I can't locate the leak. Now the engine is blowing oil everywhere. The crankcase is quite overfull. I don't smell diesel in the oil so I suspect the hydraulic pump is leaking into the crankcase. I could use some advice.

Too much oil in an engine is very bad for the engine.

Make sure you drain any "excess" oil out, and don't operate the tractor unless you can control the oil levels.

Do you now have "blowby"?

Have you traced the hydraulic lines to verify where the pump is?

Hi Clifford
Yes, I did drain the surplus before starting it, and yes it has been displaying some blow-by for a while. The hydraullic pump is driven off the back of the injector pump. It seems I created two threads, if I can figure how to eliminate this one we will move to the other. Thanks
