Loader Quick Connect Stuck - Can't Remove

hollywd75 · Jun 16, 2019

Hi, I recently purchased an IH 454 with Farmhand 22c loader. The second time I used the tractor the bucket stopped curling (argh!). It's mostly stuck in the down position. If I rev up the throttle it will move a little more the first time, then it goes back to barely moving at all. After research I am hoping that it is the quick disconnects becoming unseated.

The one QD I was able to get off easily. This one had some drips of fluid around it, so I was hoping it was the problem. It is the one on the loader arm side though. This one also looks newer then the other QD, like it was replaced at some point.

The other QD I cannot remove, it is totally stuck. I have moved the levers around to relieve pressure. I sprayed the area with PB blaster. The collar moves readily enough, but I cannot remove the other end from it. Any suggestions? I tried to research it but doesn't seem like this is a common problem.

Is this what happens with QD's go bad? If I can't get it off, does that (hopefully) mean it has an issue and could be my bucket curling issue?

Thanks!

Did you just connect the loader?

If so you may have the hoses connected wrong, causing it to dead head?

Engine off, cycle all controls, try removing again.

Try rotating it in the coupler! Sounds like the little balls in the coupler are siezed! Also try to get the PB blaster or wd40 in between the collar and body, to where the little balls are!
Good luck! Dave

No, the loader came all connected. Everything worked fine when it first arrived. I used it one day no problem, the next day I brush hogged and the curl kept rotating down on its own. Then when I went to park it bucket down, it wouldn t rotate all the way down.

Since then the bucket barely curls at all, maybe a couple inches if I m lucky. I m hoping maybe when it was delivered the QD got jarred loose or something. Really hoping it s not the cylinder or something else! I have a grading/moving stone project waiting on this tractor.

I will go spray the blaster up in the collar and let it sit for a bit. Wasn t sure that was safe to do. (not a mechanic, been learning as I go). Will also try rotating, good idea. Crossing my fingers!

When you try to curl the bucket, can you hear the engine load, the pump whine?

If yes, then the coupler is blocking the flow, or there is a mechanical bind (neither likely), or the plumbing is reversed, one cylinder fighting against the other.

If no pump load, chances are an internal seal is blown or the piston has come off one of the cylinder rods.

Shut tractor off move levers to the end of travel and hold for a few seconds to relive the pressure. If the hoses seem pliable, and not stiff like they are tensed up you should be able to remove them. If not you could also just unscrew the threads to the couplers. With this method have a protective layer between you and the coupler threads so you don't get squirted with oil. Then change the couplers with matching styles so they will work together. Should solve the problem.

Hi, possibly the QD is half off and the cylinder side hose is under pressure, at one of the hose connectors on the cylinder side just loosen it enough to start to leak and let it leak until the pressure is
off.
Becareful not to loosen the connector to the point were it blows off.
You can also have this problem with QD's when you disconnect when the temperature is cool and the oil is cold and then sometime later you try to re-connect and the hoses are in the sun where the temp of the
oil has gone up and expanded the oil and now there is pressure in the hydraulic lines.

It is off! I sprayed more PB blaster up inside the collar and let it sit for several more hours, also tried rotating the male end. Went back out and with some more wiggling around it popped off, whew! I was ready to loosen one of the fittings to relieve pressure but didn t have to.

The male end is coated in rust, so maybe it adhered to the little balls. I wonder if the whole coupling should be replaced? The inside of the female end looks fine.

Have to run a quick errand then going to re-connect and pray this works.

Steve, if I recall correctly I think I do remember the engine loading/pump whining when I tried to curl. I ll listen for that if it s still not working when I go back out.

Thank you everyone for the tips! Hope this works!

Well I am disheartened to say after all that the bucket is still behaving as before. The curl cylinder will move a couple inches sluggishly and that is it. The lift arms seem fine. It s stuck in the bucket down position so I can t even use it for my back dragging project I needed to get done ASAP.

Looks like I ll be researching redoing cylinders on this loader, I hope it is not hard.

Thanks for all your help - at least I was able to get the QD off.

When you try back dragging does the bucket hold rigid or does it rotate up on it s own like it is limp? I am guessing the piston came off a cylinder rod like Steve said. The Du-Al loader I used to have had a bad habit of doing that till I Loctited the piston nuts.

hollywd75 · Jun 17, 2019

Good question, I haven t tried since the bucket get stuck. It is opening down and I thought I read it is not good to back drag like that, so I didn t even try.

When the weather cooperates I ll get it out and see what happens if it s floppy or firm back dragging. Looks like rain after work most of this week.

I was also going to attempt taking the caps off the valve and make sure there is no crud in there, read about that too. I haven t been able to get it into float mode so that was on the to-do list anyway.

hollywd75 · Jun 17, 2019

Tried the back dragging, had limited space because of muddy ground. But in the few feet I could try, the bucket did try to rotate flat on its own. So I guess it is the piston?

Time for more reading on fixing that.

Also had tried redoing the QC s again and that same one was a bear to get off again - may be time to replace it.

Thanks!

The male end probably fell in to the dirt when it was disconnected and it rusted making it bigger, replacement may be the best bet.
