    John Deere 2040 with Open Center valve on FEL

    The seller didn't do much other than get the tractor running before I bought it. They are a re-seller. I'm going to look for the valve and see where that takes me.

    John Deere 2040 with Open Center valve on FEL

    Update time.... I purchased the cc conversion plug on eBay and it arrived yesterday so I installed to test, and it did not work. I'll pull it all down again next week, when my new hydraulic filters come in and I can change the oil (hopefully getting rid of the last of the water) and see what...

    John Deere 2040 with Open Center valve on FEL

    Thank you much to you guys. I’ve ordered the correct part (I hope) online, and will be waiting for it to come in. I’ll update when it gets here and I try it out. Looks like some time to spend cleaning this thing up and re-plumbing the mess that is these hydraulics...

    John Deere 2040 with Open Center valve on FEL

    Tx Jim, I think you are right - I think I see a seat in there. See pictures and let me know what you think.

    John Deere 2040 with Open Center valve on FEL

    Please see picture of back of the valve as well as the plug. note that there is also a plug on top of the valve. Not sure what that is but I have shown it in the last picture.

    John Deere 2040 with Open Center valve on FEL

    Well, I finally managed to perform the test - and shot milky white hydraulic fluid everywhere. Good news is now we know for sure... I also took a closer look at that valve and think I see the plug/port that Tx Jim actually referenced. I’ll get a fluid change and start planning for re-routing...

    John Deere 2040 with Open Center valve on FEL

    TX Jim, I do indeed have the adapter that you noted (see first pic). Note that it is on the right side of the control, and the hose runs back to the side of the transfer case (see second pic). I did NOT buy the proper plug for that, but will grab one tomorrow to do the test you mentioned...

    John Deere 2040 with Open Center valve on FEL

    Thanks Tx Jim, I'll try the test this afternoon before changing fluid. Since I am picking up the 1" plug for the rear of the tractor after work, do you know the size cap or plug I will need for the return fitting? I'd love to kill two birds with one stone here.

    John Deere 2040 with Open Center valve on FEL

    While I’m draining the fluid, I’ll pull the lines from the valve to try to get more info on it. I did get the rear remotes back - for now, I’ll just clean them up and store them in the barn. This is how I got them...

    John Deere 2040 with Open Center valve on FEL

    I’ll grab some oil and a pipe plug this afternoon and change both. I’m assuming I will not be able to get all of the oil out of the lines just by draining. Is there an additive or something I can use in the new oil to help finish getting the remaining moisture out? As best I can tell, that...

    John Deere 2040 with Open Center valve on FEL

    These are the pictures. I did not have time this evening to do the test that you mentioned, but hope to do that tomorrow night. Everything appears to be hooked up properly for the front and loader as all of the functions match what they are supposed to do on the control. I am also including a...

    John Deere 2040 with Open Center valve on FEL

    I will get you some better pictures tomorrow afternoon. I really appreciate you taking the time to look this over and to help. This is been a pretty frustrating experience for me but I really would like to keep this old tractor running and use it.

    John Deere 2040 with Open Center valve on FEL

    It’s a long story. Basically bought the tractor on a handshake from a local guy with a good rep. I don’t believe he sold it to me maliciously, but he didn’t check it out the way he promised to either this is back in October. I used it the first day, scooped a load of sand (not even a full...

    John Deere 2040 with Open Center valve on FEL

    I’m assuming that’s why it sounds almost like it has cavitation (tapping sound) in the lines when you operate the loader?

    John Deere 2040 with Open Center valve on FEL

    These are the only pictures I have at the moment. I’ll get better ones tomorrow evening when I am back out there. It sprung a leak from one of the hoses yesterday so it’s going to be down until I get that replaced anyhow.

    John Deere 2040 with Open Center valve on FEL

    Serial number is 317012 L. Just got this thing back today. I bought it from a local fellow that has been buying and selling tractors for years and actually has a pretty good reputation locally. Unfortunately, he has not been all that helpful to me... FEL works fairly well, but, since getting it...

    John Deere 2040 with Open Center valve on FEL

    So, I’m kind of a newbie here. I recently purchased an older John Deere 2040 with what I’m being told is closed center hydraulics on it. The tractor has a “newer“ John Deere 521 front end loader on it that has a valve for open center hydraulics on it. According to the guy that has looked at it...
