Remote and Loader Leaks

[ChrisNoeldner]

Good Morning
I am new to the forum, so hopefully I am not breaking too many rules, or missing a previous post.
I have a M9540DTC (2006). This has been a brutal winter in SD, and lots of hours and cycles on all cylinders and remotes.
I have some leakage from the "quick connects" The remotes in the rear have male pioneer couplings and original Kubota female couplings. They are seeping more than what should be "normal". Is there a way to replace an O-ring in the female side to prevent leaks?
The loader is all Kabota "flat faced couplings" or what it comes with from the factory. These are leaking a little, but if I a doing some, I might as well do them all.

I built a nice shop for her to sit in, but she may get banned if she is going to leak on the concrete next year when it is finished.

If there are replacement parts, short of replacing all of the female couplers, i appreciate the feedback.

I've never had good luck trying to rebuild a coupling.
But and sadly most expensive, is to get new couplings for the lot.

The rear couplers have O-Rings inside that can be replaced easily. Usually when they begin to weep it means that there are nicks or flat spots on the O-Rings. Just reach up inside with a O-Ring pick and pop them out and put new ones in. Used to do it all the time on our fleet of farm tractors of many brands.

Interesting in as much as both my M9 and my 105 have Pioneer QD's on the loader quick disconnect blocks...

I've had mixed luck with replacing 'O' rings in couplers. Sometimes they seal, sometimes they don't. I keep a few extra on hand all the time, just in case. I'm always changing out implements on the back end and changing hydraulic feed lines.

One thing I've learned about the rear remotes especially is, I make sure the male is clean before inserting and I keep them capped when not in use. I see many tractors where the dust caps are missing and inserting a male into a dirty coupler is asking fr a leak down the road.

Thank you for the response! Are they an off the shelf O-ring or a special Kabota part #? I have looked in the parts manual for them, with no luck. We have a good local shop supplier where we get bearing and the such, he has helped with other O-rings for other things.

We do keep them clean when attaching implements and the loader.
Our loader is a flat faced coupler, but maybe the previous owner replaced them. I like them for cleaning, but they seem to be a little more challenging to connect at times. Large temp changes seem to be the worst.

So far I have had decent luck just picking the O-rings out and cleaning the inside of the remote and the O-ring and re-installing the O-ring. I did get the seal kit from my dealer also so I have spares.

O ring kits for Pioneer will be available at about any farm store like TSC for instance.

Thank you. I missed them.
