3000 hydraulics.

Split a 3000. and parted the hydraulic line manifold from the right side of center case, now it leaks, Are O rings the only seals for this or am I missing a gasket between the lines manifold and the case ? Thanks Gary
 
I'm not familiar with the 3000, and looking at the parts manual I can't be sure where exactly your leak is.
The CNH parts site may help clear it up. Type in your model on the upper left.
Let us know!

I'm assuming you have the old style setup that has both lines hooked together to a 3 bolt manifold?
If so then yes orings are the only thing that seals them. Replace them.
Some guys have been able to find a standard round type oring and use that with good results.
I always just bought the original square cut oring from the dealer. They are not expensive.
 
Thank you both for your input. I have visited the CNH parts site before looking for the PTO coupler and fork and such. The manifold and such have no illustration that I could find, so that is why I inquired here. I assumed that those o rings were not standard items. I'll try to obtain the proper ones.... Gary
 
The drawing that shows that manifold and the o-rings is in the "Hydraulic Pump" section of the 3000 parts diagrams, not the "Hydraulic System" section.

The o-rings are 3 different sizes, so if you got them mixed up when you put them back on, that may be why it's leaking. Also, they may be worn, so best to replace them anyway.

The first one listed looks to be the upper one toward the front of the tractor:
Part number: 272344 - Description: O-RING, 90 Duro, .487" ID x .103" Thk, Tube Assy. to Center Housing, Years: 01/01/1965-09/30/1969

The second one appears to be the lower one towards the front of the tractor:
Part number: 87054S95 - Description: O-Ring, 90 Duro, 1.062" ID x .139" Thk, Tube Assy. to Center Housing, Years: 01/01/1965-09/30/1969

The third one appears to be the one that's between the upper and lower ones in terms of height, and towards the rear of the tractor from the other two:
Part number: 87035S95 - Description: O-Ring, 90 Duro, .625" ID x .103" Thk, Tube Assy. to Center Housing, 2000-3000, Years: 01/01/1965-09/30/1969
