Sc2400 Valve Question

[Hozen]

Anyone here familiar with the hydraulics on an Sc2400? I want to find out if my valve has a port for power beyond or how I might be able to add rear remotes controlled independantly of the FEL.

I would assume it would be similar if not the same as this

There a picture I posted of the loader valve here, which I think is what would be used.

I've been thinking of going with the WR Long kit as I think it's around $600 bucks. That's what it was the last time I checked it out anyway back in November. I figured that would be the easiest way to go.

Your machine is very similar to the Yanmar built JD's like gt just referenced. I belive you will need a Power Beyond kit for your machine-then you can plumb in a new valve.

Looking at those pictures of the power beyond for the 2305, it doesn't really look the same... My wifes uncle has a 2305. Maybe I could look at his to compare. The JD 2305 isn't really the same as the Sc2400. Its not like the JD 790 and the 3200's where they are pretty much the same tractor. I'll have to take a closer look at my valve and see if I can try and guess at whats what.

You can locate a parts manual for the Sc2400 here.

PDF Manual Web Archive

Hopefully it allows you to enter in your model number and serial number and not direct you somewhere else. The manual is about 31 megs in size.
A picture of the loader valve and part info is on pg 138. Quickly glancing through it, I didn't notice a full schematic of the hydraulics but I could have missed it.

Looking through the manual, it looks like the valves are covered from pages 128-138. Attached are some pictures. Figure 73, img 90 is the 3pt lever/valve

I took a look at mine tonight... Maybe someone can shed some light on what I'm looking at. So, I see the 3pt valve with the speed control knob and three lines going from it to the SCV for the loader. I see the lines from the SVC going to the quick connects under the tractor for the loader. What I don't see is any place on the SCV for power beyond. I felt around with my hand on the side I couldn't see and think I felt a port, but I could be wrong on that. Plus, it's only one... Now, what gets me is the 3 lines. Shouldn't there be 2 lines? As in, one coming from the pump and one going back to the resevoir? Or, do they have two lines coming from the pump and only one return? Doesn't make sense to me.

 

[Hozen]

So, wanted to add that I got to thinking about how the 2450 with the backhoe works... I mean, it needs hydraulic pressure back there. Does it feed off the lines from underneith like the loader or have it's own lines? If it has it's own lines and shares the same valves as on the 2400, I should be able to copy it, no? Anyone with a 2450 want to share how the hydraulic for the BH is hooked up?

This is the key here, finding out how they feed the backhoe. Is your dealer no help?

If you go to the parts manual look up and type in sc2450 as the model and serial number of 0, you can look at the parts manual for the 2450.

I have an Sc2450 I downloaded the parts manuals hope this helps,

If you want me to take some pictures let me know.

 

[Hozen]

Okay. Looking at the 2450 parts manual, I see on page 126 a remote for the backhoe which would be mounted on the left side of the tractor in the rear if you are looking at it from the rear. msb1766, can you confirm that's where you hook up your backhoe? The thing that gets me is that sheet only shows one line... so, where is the return? Also, it's coming off a port that I have a line coming off of on my 2400. I'll have to do some more looking and tracking down to figure out the differences.

 

[Hozen]

Okay, it's late and I'm retarded... I took another look at the picture and realized what was going on. On page 126, hose "5" gets hooked up from the SCV to a female quick connect on the back of the tractor... Also on the back is hose "7" which has a male quick connect that runs from the male end of hose "5" back to the 3pt valve. On my tractor, this line just makes a direct trip. So, for all the hydraulic experts out there... what are my options for a set of remotes out back? I could take the route the 2450 takes, but I'd have to be able to control it somehow which would mean an open center control valve, I assume. No idea where I'd mount that. Hmmm...

Hozen,

I was wondering if you were able to figure out something for rear remotes on the Sc2400? I've been meaning to hit up the Cub dealer I got mine from and take a look at how the hoses are hooked up on the Sc2450. I like to see things in person as to me it's a littler easier to visual what needs to be done when I can see it instead of looking at pictures.

I read somewhere that the 2450 has two pumps, the power steering and the BH are on the same pump, the PTOs and the FEL is on the another pump.

So my first guess is that the lines that feed the BH and would in turn feed a rear control system would come from the power steering feed/return area.

When I take the BH off of my 2450 there are two lines just above the PTO, I have not looked where they come from or go to but there are two.
