3000 Hydraulic pressure pipe at pump came out

[dford]

1971 ford 3000 Has anyon ever replaced the high pressure line off of the pump? Line poped out of nut at pump. Is there a change in style of fitting?

There's been some improvements to the fitting. You'll need a new fitting, and make sure the pipe isn't damaged or rusted. Also make sure the pipe enters the pump squarely.

It will be next week before I can get a picture. Tractor is at cabin.
Also no rust oon steel line, what I could see there was no damage to the small ring on pipe.
Thanks for your help. I am having a dealer try to get a new fitting but, they are not sure.

Reference #72A is used at both ends of the pressure tube. It is a lousy diagram in that regard.

I posted the same message in another, similar thread but figured I would post it here, as well.

I don't know if anybody out there is still looking at this thread but maybe this post will revive it. I have na early 70's Ford 2000 tractor that has developed a hydraulic leak in the pressure line. I know this thread is regarding the nut on the pressure line at the pump but my leak is coming out of the inner or smaller nut where the pressure line meets the housing under the right footrest. In looking at the New Holland website parts store (hydraulic pump assembly, diagram attached), the number on the diagram that is leaking for me is #72. Part #70 is the whole assembly--large nut, O-ring, and small nut. I was wondering if anybody would know if it is necessary to replace the whole assembly (part #70) or can I replace just part #72? Further, is part #71 (O-ring) used on the smaller #72 nut or just on the larger nut?

I can do basic mechanical things but am by no means a mechanic. Will it be difficult to replace the nut? Supposing it's the little or inner nut, is it just a matter of unscrewing part #72, starting the new part, inserting the pressure line, and fully tightening?

Sorry about all the questions, I would just like to replace the right part instead of replacing things with a shotgun mindset.

Thank you in advance for any assistance.
