John Deere 3010 loader issues

Hi guys, hoping someone can help me out with this issue Im having with my JD 3010 and loader, Ill do my best to explain whats going on and post pics.
 
Sorry I had to break this up in to a reply as the forum wouldn't' let me post the entire thing right away.
Last fall i drove the 3010 in to the shed for the winter, occasionally started it up over the winter but couldnt lift the loader arms or bucket while doing so. Begin Wisconsin and very cold i thought originally that maybe some water had gotten in to my lines and froze up. Coming in to April here I now realize that inst the case as any water would be thawed out by now, so looking for some assistance in troubleshooting this issue.
 
The way the system is set up is as follows, The far left hand dash lever for hydraulics must be in the up or release position, previous owner made a hook out of a nail to keep it up, for the separate aftermarket loader controls to work. With the hydraulic lever in the release position Im guessing it is passing fluid out of the junction block located at the rear of the tractor close to the 3pt, then lines are run from that block to my loader controls mounted for arms and bucket, which then sends fluid as needed to either.
Currently with the dash Hydraulic lever in the up or release position there is no movement of the loader arms and bucket when moving either bucket control lever. If I take the dash hyd lever out of the release position and push it down or applied, the arms and bucket move very slightly, arms up and bucket pushed to the ground so what would be equal to sending fluid to them from the bucket control levers. Again only slight movement when doing that. Then I put the dash hyd lever back to the up or released position and I can use the bucket controls to lower the arms and bucket back down slightly, so releasing pressure.
The hydraulic pump does work, both power steering and 3pt work just fine, no issues at all, so it seems like there is some sort of blockage when the dash lever is up or applied that isnt allowing control to be sent to the bucket levers at that time. Which is why Im posting here as Im not really sure how to trouble shoot this further
Any help would be greatly appreciated, I will try to jump on and post pics later of the bucket controls and way lines are run encase that helps to clear things up
 
Are your couplers hooked up to the same spot as they always were as in they didn't get reversed did they ? Also maybe one is not plugged in all the way or went bad ?
I'd plug a gauge in the back couplers and check pressures and see if they work right.
In the end I'd hook the loader up directly by teeing into the hyd. pipes as show many times here before on this forum. The loader will work a lot better that way.
 
Thanks for the reply Mike, Yeah nothing has changed as far as lines go from last fall. I guess i'll have to do some digging on the forum and see if i can find how to bypass that block and dash hyd lever.
 

Here's the photos showing how to attach loader valve bypassing SCV(rear remotes). Do you know if loader control valve is closed center to match 3010 hyd system?

I think you are confused on how the scv levers work. Up just means oil is directed to one side of the break-away
coupling and the other side is returning oil. Down reverses the flow. At least that is how they work for a double
acting cylinder. The terms "applied" or "release" position not accurately describe the function. So the loader should
work with the lever in either position. Help me out anyone if this is wrong.
 
That definitely could be Ray, the reason I said applied and released is thats the decal on each position. And maybe the guy before me had it jimmy rigged incorrectly
 
Thanks for the reply Jim.
Quick question for you guys on cutting out that dash lever completely. I dont have a need for that remote or extra rear hydraulic
connection, as long as i have the loader and 3pt my needs are met. Would it save me any time and be okay to just disconnect those lines,
put on a coupler connection on and run the loader lines right to the control valve located under the hood that the dash hyd lever connects
to?
thanks
 
Are you sure one of your levers on the back of the tractor where the hoses plug in sn't pointing
straight back instead of out the side so oil can flow?

Early 3010 up through SN 016590 breakaway oil control handle(parts key 34A) points rearward with oil is turned on.

If what you state is true then why is valve marked with "in" & "out" ports. I think pressure needs to be supplied to "in" port on FEL valve.

Yes you could route FEL control valve hoses directly to SCV under hood BUT IIRC you'll need to R&R hood to access fittings.

Attaching FEL valve following photos I posted will give the loader faster reaction time and aid in operation when operating loader when clutch pedal is depressed.
 
Buy the symptoms described I still thin he has one of the levers at the outlet in the wrong position
and not letting oil flow whichever way that happens to be for his early model tractor . Then again
maybe I should just keep my fat fingers shut

I agree that you could be correct and that oil flow isn't turned on at breakaway. In my earlier post I was just attempting to clarify that 3010/4010 breakaway coupler has 2 different style of oil control levers and when earlier style arm is pointing rearward that oil is turned on.

Can you tell me if that set up will also work on a 2510 JD?
That is so you don't have to use the remote hydraulics to run loader correct?
Thanks
 
Yes: It will work on 2510 same as a 3010 or 3020 [early]../ And yes you won't be using the valve [under hood] or rear remote outlet.. Loader control valve gets plumed directly to pressure & return ports on tractor.. Improved loader performance & better for hyd. pump....

At the risk of sounding really stupid, how do I tie in both lift cylinders and tilt cylinders?

Excellent images and info there Jim

The idea is to avoid using the SCV as a supply and return.

The loader will require it's own dedicated "joystick" two circuit control valve. Usually permanently bolted to the loader frame on older and smaller equipment.

I understand the concept but I have a 2 lever control for my loader. Up and down, and bucket control. How do I hook up both controls?
 
Alright I went and looked at my hydraulics.
I now understand I only need one inlet and one outlet.
Thanks for putting up with the questions.
 
Thanks again Jim for the help on this, its really appreciated.
Just to clarify, and i apologize for asking but just want to make 100% sure before i start plumbing wrong. Here is another thread with a couple extra pics in it i found while doing some more research http://www.yesterdaystractors.com/cgi-bin/viewit.cgi?bd=jd&th=503973
The line labeled AK40464 is the supply line Teed off of the existing supply correct?
AN140263, what is that line for?
In the link posted above for a 4020, is the top pic his return line, and where would i plumb my return for the 3010
Thanks again for the help!!!!

I can see where the return line is located but where is the pressure line on my 2510? I can't tell from pics. Also are the part #'s given JD #'s? Thanks for all the help. I'd be scratching my head along time without all the info.

AK40464 & AN140263 are part numbers utilized for making FEL valve connects to tractor for hyd fittings not hyd lines. Return FEL valve oil to where 90° fitting circled in red is attached to LH side of trans case(PHOTO's) or ported hyd filter cover. Photo's are same locations but from different views.

Pressure line attachment is basically the same as previous photo for 3010/4010 & early model 3020/4020. Yes part numbers are JD part numbers but hyd fittings are also obtainable from a good hyd parts business.

I apologize for not being able to find my pressure line. From the pics I cannot tell where it is on tractor. The return is obvious to see. Is pressure line in same area? Once again I apologize and appreciate your patience.
