Any idea what this valve does?

[tomildinio]

Its on a JD 6230. Pipe comes off it, disappears under the cab and I cant see where it goes then. Somewhere near the hydraulic pump. Either way, its pissing oil.

Cant find diagram on jdparts either.

Would it be the TLS?

Many thanks.

The hose with the elbow to the left of the steppermotor goes under the cab floor & up to the steering valve.

It's a hose to the back of that valve chest. Starts metal before turning rubber then disappears beyond reach. It only has oil coming through it intermittently but a lot of it

Ahhhhhh, right.. That's the trailer brake valve. It's the return pipe that you're looking at..

Thanks a mill @Tractortech
That would make sense.

Guess I'm learning to tilt the cab today!

can you not reach it through the plate in the cab floor

 

[tomildinio]

Thanks bobthebuilder.

The plate over the fuel tank? Is there another plate? I'll have a look.

 

[tomildinio]

Removed the floor plate. Can't fit in still. It would be to the rear of the seat kind of direction.

Is it definitely the leak off from the trailer brake valve that's leaking??

 

[tomildinio]

I think so. It's hard to say because it comes out at such pressure. But it's not a constant leak. More On and off every 20-30 seconds.

Imo it's the rubber part of the trailer brake actuator pipe. But I can't even get a hand in. Might pull the trailer brake fuse and see if that stops it. Still waiting on jd mechanic...

Removing the 'trailer brake fuse' won't stop it leaking!! There's nothing electrically actuated. The fuse is for the trailer brake lights....
