Rebuild JD Hydraulic QC Coupler?

[Thom2]

I've got a couple of hydraulic quick connect coupler that are leaking under pressure.
Can they be rebuilt? I've searched the Net, but haven't found anything about rebuilding them.

Here's a link to my QC coupler.

The diagram shows an #2-O-Ring & #3-Backup Ring.
I've looked at the old coupler & can't find any way to disassemble it.

My local NAPA store makes hoses. You might want to check with your local NAPA store and see if you brought your hoses in would they make the repairs or sell you what you need to do it yourself.

Are they Pioneer Couplers?

From what the diagram shows you should be able to dig them out with a pick and install the new one's. I only replaced a few that were leaking with the male plugged in if they weep when nothing was plugged in I replaced the QD.

Most of the female QD's leak because some one isn't careful with the male
or the gosinta as I call it.

The tip gets a nick on it and when you assemble it in to female (gosonta) it cuts some off the oring and leaks.

check and fix your gosinta's before you fix your gosonta's

I took Kenstrac advise and picked out the O-ring & Backup ring. The Backup ring is neoprene. There was a really small nick in the O-ring, but the Backup ring was pretty rough on one side. Here's the Photo of the rings.
