Any unused JD hydraulic lines with 3/4" banjos?

Any unused JD hydraulic lines with 3/4\" banjos?

Just a long-shot:

Does anyone out there have any used hydraulic lines with 3/4" banjo fittings on them that they would like to get rid of? JD uses a lot of these.

I don't care what shape the tubing is in as long as the banjos are in re-usable condition.

Thanks!

Hi Tom, I may have the third line (new, unused) that came with my power beyond kit. I'll check tonight if you think that's what you'll need /forums/images/graemlins/smile.gif

Robs,

Yeah that should have the fitting on at least one end. You might also have the lines that the power beyond kit replaced. They would have two fittings each. I would like to get at least three more, and preferably seven so I can get the new lines ready before I tear it all apart to make the job go faster.

I've attached a picture of what they look like. The through holes are 3/4".

Email me and let me know. (trscott at sterling dot net)

Thanks! /forums/images/graemlins/smirk.gif

And here's a picture of them installed.

And finally here's a picture of the hollow bolts. If anybody has extras of these they want to part with at a savings over the JD prices, I'd take those too! /forums/images/graemlins/smirk.gif

I know I've got a couple of the bolts. I'll check on the rest tonight /forums/images/graemlins/smile.gif

Tom,
Have you taken the bolts to a hydraulic store, to check to see if they have a fitting with the same threads. There are several different straight thread fittings. There may be some that will work. I will say that I have never tried to replace banjo fittings with regular hydraulic fitting, but you appear to have enough room if you can get the correct threads. The regular fittings would also have better flow.

Re: Any unused JD hydraulic lines with 3/4\" banjos?

I originally started out down that path, and even bought a bunch of standard Parker fittings with straight thread O-rings in SAE-8. The trouble is that there is just not enough clearance for them, either the ELLs or even the straight couplings in some cases. I could use the straight couplings could work in a few places, but for instance on the control valve supply ports, the tubing would end up jutting out where it would be very vulnerable to damage. Whereas with banjos, I can get the tubing to lay flat against a mounting surface almost right away in the first few inches of tubing. Just much nicer layout even if the other fittings could work, but in most places they won't.

I really don't think the flow restrictions on a banjo are an issue. We're not talking a lot of velocity here, and I've calculated the cross-sectional area through the banjo bolt and fitting, and you might be surprised to know that it is larger than the tubing. I don't believe there would be any perceptible difference in performance at all. Far more important to me is to get plumbing that lays flat, is less likely to get damaged because it doesn't jut out in the way, and looks clean and organized.

There is another consideration too that I initially overlooked, you have to have an O-ring seat cut into the female port, which not all the ports do. Parker sells a pilot cutter that will cut this O-ring seat, but then you've got to worry about keeping the metal chips out of the system.

I actually have about a hundred dollars of SAE-8 O-ring fittings that I need to try to return to Parker that are pretty useless to me right now. /forums/images/graemlins/frown.gif

JerryG,

re: "...you appear to have enough room..."

If you look at the picture of the installed line a couple of postings up, the only one that a standard fitting will fit is the one to the left. The fitting at the other end of that "G" shaped line could take a straight coupling, but an ELL doesn't have enough clearance, and the tubing from a straight coupling ends up right in the way. Worse, if you look below that one there is another banjo fitting which I also have to tap into to get the low-pressure tank-return, and that one is jammed right in front of the rear axle without enough clearance for a straight or an ELL, and it's other end is just as crowded. Finally, the three ports on my SCV are all lined up next to each other (Prince LVT), so you can only spin an ELL into the outer two and would have to use a straight coupling with a tubing bend on the middle one. I tried to like the looks of that, but three banjos would be MUCH cleaner!

One way or the other, I am not going to settle for a plumbers nightmare, even if I have to fabricate these banjos.
