Curious About Hydraulic Connectors

[Texasmark]

Recently purchased an early 1990's CIH 895. Hooked it to my '91 JD baler, connections seemed to mate just fine, and did several days work. Today I noticed that there was hyd. fluid all over the rear of the tractor and the Hyd. Fluid sump, which had been over the full mark, didn't even show up on the dip stick. Upon observing the above I cranked up the tractor and ran the 3 remote controls through ups and downs, listening to the tractor, at idle, to load up as the pressure increased since I had nothing connected to the remote outlets. After that exercise, I found no leaking fluid anywhere.

Question I have is possibly similar to the early JD connectors that were brand specific: Did CIH have a peculiar connection that doesn't mate to current day Frontier, popular connections? If so, what are the nouns that one would use to obtain said connections?

As usual really appreciate your guys and gals responses.

The early Deere and IH are not compatible ......... Probably!

There are many different hyd ends. Generally, there is a number on the tip. The best way to start is to get a chart and see what you have

Also, you could have some bad O-rings in the tractor outlets..

I'm fully aware that the early JD connecto only fit JD equipment or a JD connector on other equipment. Bad Orings is a thought. With the implement connector disconnected, the Oring wouldn't have shown up on my test so that is a possibility.

I guess what I have to do is reconnect an implement and see if the loss of fluid is from a connection or elsewhere, maybe a leaking PTO seal. That would be a better idea as a rotating shaft would sling oil all over the pace and that's what I have.
Thanks

Your tractor has, for all intents and purposes, standard Pioneer style connectors. The industry had settled on those by the mid 1980's.

If the hydraulic fluid had been leaking while you were baling, your tractor would be literally "tarred and feathered." If the oil is clean the leak developed after you parked the tractor after the last day of running the baler. Hoses blow even when just sitting.

I would suspect a cut o-ring in the female side of the coupler. Or of the end has been hit on something they will get out of round just enough to leak when not connected to something. The new coupler tips seem to be made of some soft junk material that will deform easy . The old ones the ball would rust if left outside during wet periods of time and leak due to that. IT seems like we are constantly replacing coupler tips. The older coupler tips were made out of a harder material.

After further investigation, while I was under it changing the hyd filter which i was going to change when I bought the tractor, but the fluid level was high and I said I'd get to it when I got to it. I saw hyd. fluid all over under the rear of the main frame. Looking up at the remotes, they were covered in oil....so, possibly the remote running the gate blew, probably a hose up there, since this baler gate tension rises as the bale forms up to a max of 3000 PSI when the over pressure switch opens. It doesn't have separate cylinders for bale forming and gate operation.

Not easy getting to the valves and the cab just makes it harder to trouble shoot and repair so I think I will swap remotes running the gate/bale tension and see if that helps. A second hyd. system is the tie arm and it's very low pressure. Since the tractor has 3 remotes, and one seems to be seldom used, I will plumb that one to the baler and see what happens. But that will be next year as I am through baling for the year.

Thanks for you folks comments.

Might as well track the leak down now while it is fresh in your mind .you will have to fix it one day anyway. Will only get harder as age works .
