Leaky Hydraulic Couplers.

[L.Fure]

I'm sure this has been discussed in the past, but I don't remember the outcome. I have leaky hydraulic couplers on my 600B. They leak while there is nothing hooked up to them. Is there any way to stop this without replacing the coupler?

In a discussion on couplers after I had re
done mine, John Saeli informed me that he
sells the o-rings to rebuild them.

Thanks for the quick reply Tgrasher. I'll look into rebuilding them. Are they hard to dismantle?

I started with cleaning the hyd filter cartridges,and then the sump. It was not until then, that I rebuilt the couplers. Just as a note ,I used grease to hold the eight balls in place on the final o-ring replacement.CM

Easy peasy if you have a parts break down
and don't loose any. The coupler can be
hard to get to turn so use a vice with a
rag to protect it. I had went to a Case
dealer and they priced G119A piston
complete with seal for $125.00. I'm betting
they don't sell very many.

Saeli has all the o rings, and springs . Let me know what you can not find. Look at the parts break down carefully. If you do not have the parts list , I will post it for you.CM
