In front of the seat the hydraulic lines come into the box with the control levers. We replaced all the lines. The shop gave us
o-rings for the banjo bolt seals, but it leaks. Can anyone guide us on the proper seals? We have heard bonded washers, copper,
and o-rings. I also looked in the abbreviated shop manual I have and could not find torque specs.
 
The seal that goes on the banjo bolt is an o-ring. The seal that goes between the fitting and the valve should be a square cut o-ring. I don't have parts numbers handy, I avoid the NH parts site like the plague.
 
Thanks. There is a recessed hole in the cube fitting that the banjo bolt goes through. Everyone thought the washer should fit inside there? I attached a photo of the recessed hole Where are the banjo bolt comes through and a picture of the hole in the tractor.

That recessed hole is where a "square cut" rubber o-ring goes. Not a copper washer, not a round o-ring. It's in the parts book, such as it is.
