I have a 2950 that when useing a one way cylinder the empty coupler is leaking oil. Is this something in the coupler or selective control valve?
 
Pressure up the side that is leaking and see if it's leaking through the ball or around the sleeve, my guess is around the sleeve, my hydraulic test bench lets me pressure test them on the bench,, a lower coupler kit is what you need,AR82570
 
Tim the john deere parts page shows that number to fit alot of them but not a 2950.I Don't see a kit for the 2950.
 
That part # is for the JD style couplers. 50 series would have ISO couplers. Same method of troubleshooting but they have a poppet with a rubber washer instead of a ball. I think you have to buy individual pieces instead of a kit. Maybe TxJim will post a picture?
 
I could not locate a seal kit.

You are right Cliff,,I have those old numbers burned into memory,,the 50's are a bit more complex, and there were a few changes as they went on...
