BX24 HST Leak?

[Ngiovan]

Hey guys,

Did a HST Service last week, and I’ve noticed a Leak since. Maybe an overfill?

Seems odd that it just started

Where is it leaking from? What does the dipstick say?

He has two videos linked (see the orange words).

It is overfull, leaking under the “middle” of the tractor.

I suggest he gets the level at least down to the max fill line and verify the vent is open. Then try to clean it with something that will remove the leaking oil. Then see if it is still leaking.

Add the UV dye and see where it is leaking from if you want to try that, but it seemed pretty obfuscated by the tractor wiring and the floor board.

Thank you. I didn't realize the orange words were links. Good to know

It's probably leaking out the vents because you overfilled it.
And please quit calling it an HST service, it's not.
All you did was change hydraulic filter and fluid!

Very common for this vent line to go bad and leak.

Thanks for the feedback! I’ll get it back to level tomorrow and report back.

Finally got around to getting it back to level. Still has a leak, but has noticeably slowed.

Mentioned it to my local dealer when I stopped in for some mower parts and they printed the same picture that @North Idaho Wolfman posted and said it was likely the culprit.

I’ll look to address it the next rainy weekend. In the meantime, is there any concern with continuing to run the machine?

Finally getting some good weather and I’d hate to miss some hours in seat.

If the leak is really low, it could allow dirt or water to get into the hydraulic system, so I wouldn't wait to long to repair it.

Jinxed it, rained all day today. I was able to dig into the leak a bit more and looks like it’s coming from the manifold. Read some posts from guys that just had to tighten things up, others had to replace the lines. Here’s a quick Video of me poking around.

Spray it all off with brake parts cleaner, then you should be able to pinpoint the leak better.

Found the leaky fitting. After cleaning it up there was some o ring visibly blown out. I did snug the fitting up a touch which slowed the leak. Looks to be the line that articulates the bucket.

I’ll order up replacements tomorrow. Since I’m this far in, should I just replace all of the o rings in the manifold/controller? One other looked to have o ring blowout but no leak yet.

Picked up the o rings this week, and finally getting into the tear down. Man, they really make you take a lot of stuff out just to get to these… i have half a mind to just cut out enough of the battery holder to access the fittings below.
