    Leaking loader couplings when disconnected

    3 of the 4 loader couplings on my 1026r slowly leak when the hoses are disconnected. I end up with a mower deck covered in hydraulic oil. See pictures. How do I fix this?

    well Paddles-u got 3 choices for that oil drippings:

    1) replace the quick discount-completely

    2)install new o-rings in them

    3) Try spraying some w-d45 in there, to clean them, maybe some dirt got in, and is kinda keeping the o-rings from sealing up good. but i've replaced mine once now so far on my tractor(2006-2520) and after reading a response from KennyD--about doing the wd-45 spraying trick to help with cleaning-i did that-and it helped. so try that first-u got nothing to lose but a little time in it.

    them little suckers are not cheap either. but is a needed product for the tractor, especially if ya have a loader on it. good luck

    A few drops of oil is normal.


    Wipe with a very clean shop rag next time. And use the plugs to cover the outlets.

    The prior owner did not keep them clean and covered. They were disgusting and full of grime. No caps on the loader hoses at all. The caps for the outlets were beat up and full of junk. So it is highly probably there is junk in the coupling preventing it from sealing. This used to happen to our hydraulic tools in the fire department when some idiot would drag the hose down the road getting crap all over it.

    I actually just put pretty new caps on everything yesterday because of this. I just left the outlet caps off overnight to see how much was leaking.

    The pool of hydraulic fluid on the mower deck after an hour of mowing the lawn is not a few drops unfortunately. I wiped the couplings clean when I wiped up the fluid. What you see there in the photo is what dripped out overnight over the course of 6 hours, after it was wiped clean. Definitely not the expected few drops that happen when connecting and disconnecting.

    Iíve played with quite a few of these leaking couplers, the only real cure is replacement unfortunately. The poppets fail to seal, whether itís damaged or the springs get weak is still I bit of a mystery to me. The o-rings only seal the couplers while connected, so that is not the issue.

    Oh, super. What is required to do that replacement, and how much of a PITA is it?

    Kenny also sells some GOOD rubber plugs which are designed to seal the couplers much better than just the pretty cheesy covers which Deere provides when new. The rubber plugs Kenny sells will fit tightly into the coupler and stay in them, because of the way they are designed, which is the right way.

    I strongly suggest these real rubber plugs which you can attach to the tractor with a little chain or I removed the chain and simply throw them in the toolbox when removed (when the FEL is on or otherwise the quick connects are in use).

    I always keep extra couplings, both male and female, in my spare parts kit because of the annoyance they are once they start to "weep" or when they totally fail. It isn't often, but when you have a few older tractors around, you will have a need to keep spares on hand.

    As Kenny said, replacement is the only true fix. If there has been dirt and debris in the quick connects due to the prior owners "use" of the machine, a set of new female connectors is the only real answer.

    Here is a picture of one of the spare parts kits I keep and you can see the rubber plugs in the plastic bag in the center of the box. You can get the replacement quick connects, both male and female, as well as the rubber plugs in the box in this picture from Kenny's website with great service and a reasonable price.

    Once you replace your weeping quick connects, I suggest you keep your old quick connects as a back up just in case. Even though they weep some now, you just might need them as an emergency back up, in case the good new quick connects get damaged or somehow need temporary replacement.

    While the current connects drip, at least they will connect which is the main objective. Sometimes, when the female coupling fails, they will shoot fluid out up to 15 feet in a stream like a high pressure hose when you move the loader control handle. In those cases, the old couplings can come in very handy to solve that issue, at least until you can get a new female coupling.

    Just a note: The QDís we sell are not direct replacements for the OEM couplers. Ours have NPT threads, the originals have ORB threads.

    The new caps I put on it are actually the product that Deere used to use before they switched to the junk they provide now. Nice soft rubber that pops in and seals very nicely. They're legit, not junk. had I know about Kenny's prior to ordering the caps, I probably would have bought his just because. But these are definitely good caps that seal up nicely. Unfortunately leaking under pressure with the engine running will still push them out no matter what.

    Can anyone suggest a source for the replacement couplings?
