Adding Power Beyond, 3-spool hydraulic valve, and T-n-T to a JD 2520

[Sockwell]

Thanks for posting the project in so much detail. For my interests, this is one of the most informative posts I've read. I do have a question about a component. Where did you get the couplers with the snap ring groove? I've been working on a project for hoses for a FEL third function kit. These couplers would minimize the number of fittings needed. I glanced through the Surplus Center on-line catalog. If they're there, I missed them. Again, thanks for the post.

I found them at a local hydraulics shop, called Ronco (Rochester MN and Lacrosse WI). They must be in the Parker catalog, maybe you can find the part number and order it that way.

Just got off the phone with our local Parker guy. He called Parker. They told him they do not make a hydraulic quick coupler with a snap ring groove on the outer body. The best they could do was offer one with an extended body and threads that would use a bulkhead nut. Thanks for the help. I'll keep looking.

BTW, still a very informative thread. I'm trying to get the stuff together to add couplers to run a stump grinder on a CCY EX3200.

Sockwell,

Don't know if you're looking for 1/2" but the snap ring retained couplers are available from John Deere but they aren't cheap..

This is the one that is used on the rear remotes on my 4310. They are O-ring Boss (ORB) so you would need hoses with that connection or an adapter.

LVA13231 $27.57 Snap ring - M42702 $2.79

There are smaller ones available but I don't have the part numbers. What kind of flow do you have?

If you can get the threaded one for a bulkhead nut, go that route. The snapring is a tough way to do it anyway. The snapring is so small, the hole has to be so very accurate, no room for error, and if you pull too hard you can dislodge the snapring. The nut sounds like a better plan. I will try to follow up and look at the make and model on the snapring couplers I have, and add that info here later.

 

[Sockwell]

Please don't go to any trouble. There are other ways I can do what is needed. You've aready helped myself and others with the details of this post. I will probably go ahead and get the Parkers that can be used as bulkheads or use an assembly of fittings that include bulkheads.

The WR Long Third Function kit for my FEL was delivered with hoses. The hoses are too long, are zip tied to the front FEL cross tube, with the fittings hanging. They drag the ground when the FEL is lowered and, when using a grapple, debris will get caught in the hoses. I'm looking to either replace the hoses with hard pipe or with shorter hoses, with the QC's in a plate. The type QC's you used would have eliminated the need for a seperate bulkhead fitting.

I bought some Safeway S25A-2's that have the groove in the body. But I do agree with what Jim wrote about them-bulkhead fittings are much more secure. They are compatible with the Pioneer's as well.

Before I forget to do it, the torque specs I found and use are:
Banjo bolt 150 inch pounds (8 mm hex wrench).
M8x50 cap screw holding DSCV on, 17-22 foot pounds (22 mm socket).

Jim - one question if you do not mind. I will be starting this type of project soon. Where did you get the two torque specs on these two bolts (banjo and cap)? I do not have the service manual and can't find this info online.... thanks Scott.

 

[jimgerken]

Sorry, I can not remember where the torque data came from (Chemo will do that to a guy). I am sure if I posted it here, I did not make it up. It must have come from JD literature of some kind. Maybe someone can verify for you.

Awesome thread, can't wait to do this to my 2520 over the winter!
