B-2910 hyd leak Help please

gotrocks · Aug 19, 2008

Hello to all, I'm back at this overflowing well of knowledge for some directions.

Yesterday while doing some work with FEL all of a sudden a small stream of hyd oil started running out of the coupling in the picture.
First pic coupled - second pic un-coupled
Since I was ready to quit for the day and was close to the parking place I quit and left it alone.

Today, I started the engine and after a few moments a smaller leak started dripping from the same location.

I uncoupled and looked, did not see anything that jumped out at me, so I recoupled and the small leak continued.

Thanks in advance to all who can tell me what to look for - repair - replace -????????

Please be as specific as you can, since when I go to the well for info
and leave with my bucket full, sometimes my bucket has a hole in it and --- well you know the rest of the story.

Remove that fitting and check the o-ring,.. then remove the male couple end from it and add some liquid teflon and tighten it back up. If it doesn't stop leaking then the fitting might be cracked..

The reason its leaking it because you have the loader off the ground not in use,.. and the pressure in the hyd ram is being forced back and leaking through the fitting.

Replace both sides of the QD. If you have a TSC near you should be able to get them much cheaper than from Kubota. Bought my last set from Northern Tool. Price is still $10.

Thank you Jason and Ron,
I just got a chance to get back to "Tug Bota Annie" and uncoupled the line - start - bucket tip/tilt is what is controled by the the leaking connecton.

Looks like a thin wall deep socket would be desirable, BUT I don't have one. So, 3/4 end wrench - only have room for very slight movement - loosen a little then tighten a little past original spot and restart tip/tilt to stops both directions and no leak. (right now) I'll be watching and post a follow up if it starts again.

I think I was backdraging with the FEL and maybe the front dropped off a little rise and that could have put extra pressure on that connection.
