Ford 600 Hydraulic - Help

[FordFarm600]

So I recently got my grandpas 600 cleaned and running again after sitting for two years. It seems that the hydraulics are working as the lift goes up and down, but I noticed there is a lot of leakage coming from where the pump connects to the pump manifold. It’s leaking and running down to manifold puddling up on the group. Any idea why it may be doing this and what I can do to fix the leak? I am a newbie to major tractor repair. I can do the regular maintenance. Is there a gasket or between the two? Any information or suggestions would be appreciate.

It looks like you need orings numbers 36, 38 and 41 in the linked parts catalog. CNHI Ford 600 parts catalog
If you don’t know where your closest Case-New Holland dealer is you can search by the map pin at the top of that page. Secondly, you have the choice of getting the orings per their size from a local hydraulic repair shop. The size is shown in the parts listing.
Third if you prefer to get them shipped to you through a dealer reply back and I can give you info on one in PA that ships parts.
