Hydraulic Coupler stuck, its my fault, need help.

[Oil Pig]

I'm borrowing a skid steer. I connected my attachment to it and didn't realize that the hoses are shorter than they need to be. So once raised the boom and tilted it forward it pulled hard on the connectors. The bottom came off fine, the top one won't come off. Any ideas of what I can do to get it off so I can return it?

Sometimes it's just the residual pressure in the line that makes it hard to release.

Try pushing it in for a couple of seconds before trying to remove it.

You can also wait for a while and the pressure should slowly dissipate.

There's no pressure on it as i have disconnected the hose from the coupler.

I know some connections can be tuff, and know a few guys that use these to get them on/off

way more strength than just using your hands and designed for them, might be worth buying to try , sold at many stores,Ace hardware and so on, plus all over online

If it got stuck after it was pulled forward, maybe trying tapping it back in the opposite direction to free it up. try rotating it while tapping it back. the balls inside the coupler body may have gotten jammed up. Feel free to soak it down with your favorite penetrating oil.

I would make sure that all the hydrulic pressure is off by cracking the hose to coupler , 2 tap it back in and disconnect, then I would go and buy a new coupler for the machine as the little balls have possibly damaged the coupler creating a bur internally, that way I could return the unit in the same condition as I received it.
I have seen this happen where I worked also skid steers that had hydrualic hammers would wear out the quick connect couplers, they would also break internally and act as a check valve when you would go to operater the auxiliary function, and the littler balls that would retract to make the connection woud hammer in to the collar and bur up to where it would interfer with coupling and uncoupling and I have seen couplings damaged the same way by hoses getting snagged and had to replace couplers.

Nothing would work. Short of taking a reciprocating saw to it, I opted for just taking the fitting off the skid steer and replacing it.

 

[mrbb]

well thats one way to get it off for sure!

Don't know if this applies to smaller machines but on larger excavators and when using hydraulic hammers I've been told not to use quick connectors just because they eventually break but use screw-on hydraulic couplers instead. This obviously does not help "Oil Pig" at the moment but maybe someone else in the future?(!)

Take care!

the larger excavators over 10k were screw on and when the hammer was off it was capped at the valves on the side of the boom, the rubber tire back hoes had quick connect, we had JD 310 and JCB of the same size and new holland 555's

I've had issues like that before, and what worked for me was releasing any hydraulic pressure in the lines before disconnecting or reconnecting the hydraulic quick coupler. Make sure the machine is off, wiggle the joystick to relieve pressure, and then try again.
