Hydraulic Quick Connects

[thcri]

About six weeks ago I noticed one of my quick connects for my loader was leaking a bit. I didn't think much of it but today the one that was leeking a little bit became a big leak. The other three are also leaking. The one that was leaking really bad I could see the O ring came out of it's seat and was in pieces. I pulled out what I could and the O ring I could roll up in a ball. It's chemical balance or what ever was gone. I could roll it up and then pinch it between my fingers and smash it. Kind of like rolling a buggar around. I pulled one of the other rings out, same thing, as soft and as pliable as can be. I just changed my hydraulic fluid about three months ago. Should I get it out and get some new in, dang I don't have the money for that now /forums/images/graemlins/crazy.gif

What kind of fluid did you put in it?

 

[thcri]

I put in Transmission/Hydraulic fluid from Sam's. It said it met Ford/New Holland specs.

 

[JerryG]

If it did that to the connector O-rings, I would be afraid that it would damage the internal seals. I would take it out and flush the system.

I don't think you can afford NOT to change it out!

Did it say who made the fluid?? what color bucket did it come in? Just don't want to make the same error....drain it! BobG in Va

It said Sam's right on it. White bucket with black top. Monday I will call the dealer and have it take it out and put new in. I will discuss flushing options also.

I use hydraulic fluid from Sam's Club all the time, and have never had any problems. I went out in the garage and looked at the buckets and they were white with a <font color="green">green lid </font> . Made in Shreveport La.

It has been a while since I've been there, but I'm thinking the buckets with the white lids are SAE 30 oil.

Have the dealer determine if the fluid was the cause of the problem. Get in writing and then go see Sam's with some kind of proof that you got the stuff there and it was labeled to meet the specs your tractor calls for. They owe for the damage done by their product, plus something for the inconvenience above and beyone a new bucket of oil. Make sure the numbers are right first, though.

I was looking around in TSC for something equivalent to Hytran Ultra, which meets Case standard MS1209. They had lots of stuff for 1206, 1207, 1210, etc. but only one equivalent to 1209. $20 for a 2 gallon jug. Might as well buy the real stuff for that price.

You can always use a product that is a standard higher. Example:
Tractor calls for AW45, but the higher grade AW68 is acceptable, etc.
Most any universal hydraulic fluid that has anti-foaming agents meets most tractor company specs.

Why do you assume it was the oil? Maybe the manufacturer got a bad batch of o-rings. I would say change the o-rings and keep using Sam's oil, Sam's doesn't make it, probably Shell or Exxon, it's the same stuff, different bucket as you buy at the NH dealer, Kioti dealer, JD Dealer...if it meets the specs, it meets the specs. (I'm assuming here the correct oil was purchased at Sam's)

1. Murph's had this tractor for a while and apparently hasn't had this problem until recently.
2. All four QC's appear to have the same problem - O-rings going out.
3. Changed the oil about 3 weeks ago and the problems appeared in all four QC's.
4. A little too much of the same problem seems like something other than coincidence.

Since I'm the happy owner of a new DX29, I'm particularly interested in how this one shakes out. I'd hate for my hydraulics to do the same thing. Is there a cross reference for oil standards somewhere like there is for spark plugs, filters, etc.??

KiotiJohn -- while it's generally true that a bigger number on the standard represents a better and downwards compatible oil, I'm not so sure about Case. There is a MS1210 standard that is different from the MS1209 number for Hytran Ultra, but I'm not sure you can run 1210 spec oil in a 1209 system with no negative effects. They sell it side by side at the Case dealer and I think the 1210, sold under the Aksela (?) label is cheaper. The Hytran Ultra is also made by that company. The lower numbers in the Case system such as 1206 and 1207 are definitely not upwards compatible to the 1209 standard. Does anyone know for sure?

Given Sam's club as the source, could some prankster have switched lids on two pails of oil? I can picture some idiot thinking that would be a funny thing to do at 2 or 3 AM. Our 24 hour WalMart is the major hangout for the high school idiot set after everything else in town is closed, especially in bad weather.

That prankster could have changed the lids all he wants and would not have changed the substance. The identification was on the barrell itself not on the lid. And besides, getting them lids off was a major pain in the ***. Most pranksters I think would have given up unless he had the proper tools to get the lids off.

I did talk to my dealer today and he did tell me he has seen this before. And even on other brands. Which I am sure is possible as them quick connects probably are made for more than one manufacture. My dealer also reminded me that after having my tractor for about 6 months they changed out the 0 rings. So his question did they use generic 0 rings off the shelf or did they use the actual New Holland ones?? I am changing them out tommorrow and in a few months we will check them to see how they are doing. He does not think it is the oil.

We'll see.

Ah, more information. If they changed the o-rings, there is a really good chance that the problem is the o-rings. If I had a hydro and I thought that the oil was bad, I would panic. I hope that the o-rings are the whole problem. That would be great. Do this. Check the quick connector o-rings for the loader (if they are original). If they are good there, you at least know there is a better chance that the new o-rings are the problem.

Thcri,

If you/they used the wrong size O-rings, this could certainly happen.

O-Rings have very specific ID/OD, thickness, and material and are made to stretch some but not overly so.

That's speaking generic about O-rings.

Also make sure the installers didn't use petroleum jelly or something that dries out the O-rings. They should lube the O-rings a little with the hydraulic oil or installing them could tear or roll them.

Good luck, and let us know.
