Kubota L4330 dumping hydro fluid

[randy Wright]

Ok so here is a new post. I was working with tractor clearing. I heard a pop underneath saw smoke...shut down. Hydro fluid flying out under pressure when started. I took a few pictures but it is still hard to see where exactly it is coming from to the untrained eye. I am due for fluid changes almost to the hour in manual. Can anyone tell me where this fluid is pouring out of and what the repair entails. I am not in a rush. Florida weather and hobby/ just starting tree farm.

Cant seem to get picture into this post. attached?

I can't detect any wet areas to isolate the leak from the picture. Does it leak all the time or just when the hydro or the loader valve is operated.

I'd recommend getting someone else to start the tractor for you if the leak is that bad and maybe constant but if you do be sure they know how to operate it.

It does look like weeds or some thing has worked over the lower line a bit but it all looked dry.

Art, if you look close at the very bottom of the picture, just left of center, you can see oil spraying out of something.

It only sprays out when started. I cannot get a much better picture as the spray would hit camera. I do have a couple of other shots will try to post.

Here is the closest pix I can get.

Hmmm, I can't quite tell from the pix. Maybe one of the "banjo" bolts on a pressure line to/from the filter? Try looking over the parts drawings in the Kubota parts manuals. I think they're still available for free download from several sources. Try tractorsmart.com.

found my copy. Here's the inlet hst lines (attempted to attach as a MS-Word doc). Looks like it might be an o-ring on one of these.

Thanks for that diagram. It looks like the diagram is of the line that has the filter built into it. Looking at the picture High pressure spray leak seems to be coming from seal plate on side of transmission? I will attach another photo.
Do you perhaps have a diagram of this? I gave my information to request manual to the source you suggested...thank you for the help.

Ron, it looks like there is oil higher up? Then the leak is possibly on the top? You might find that the line might have a flaw so check it closely.

Going out today and putting on a leather glove and feel for leak.
