John Deere 3010 Propane... Lost hydraulics on my front loader and 3 point. Been reading a lot of forums and checked the filter and screen which were both clean. Read where you can de-stroke and then open back up to put it in stroke and it will sometimes clear any trash. My main question is- look at the attached picture of the bottom of the hydraulic pump. I also attached a picture of what they are referring to in the manual as a shut off screw which I assume means de-stroke but canít determine if that screw on the bottom of the pump is actually the de-stroke screw or the pressure adjustment screw?? I canít tell if the pic in the manual is on top or bottom of the pump. You canít see much on top as it is propane and the tank and hydraulic radiator/ cooler are in the way. There is a hole in the cover plate right above the pump and feels like there is a nut/ bolt head on top right above the location where the screw is on the bottom. So, is that the de-stroke screw in the picture?

My 4010 does have a accumulator in it. It is up by the steering and brake flow control valve. Maybe it was added later by someone. It looks factory. Not large, but it is a high pressure nitrogen filled accumulator. I bought it in 87 so who knows what could have been done for a special use years ago.

Rick, you didn't reply to my question as to how the loader is plumbed to the tractor, and if it has it's own valve.

Knowing this is IMPORTANT for anyone trying to help you solve this.

"used red mn" has a VERY good idea, to take the loader out of the equation for now, and that the problem could be in the loader valve itself (if it has one).

But you have to tell us exactly how the loader is connected for us to help you.

I wouldn't muck around with the front pump without first isolating the loader, and if that doesn't help, to check the front pump pressure to see what it's actually putting out with the loader out of the picture.

And I don't believe the "screw" in your photo is the stoke control, anyhow.

Sorry... went to bed early! See the following from my earlier post for how the loader is connected. Let me know if I need to explain better.i put the loader on about 5 or 6 years ago and connected it per directions probably from a discussion on this forum. I do think it would be a good idea to take the loader out of the equation and see if it is the problem. If I disconnect the supply, can I leave the return hooked up at the filter to do the check?

ďThe loader supply is tied in to the line right in front of the brake pedal on the right side... there was a 90 there and I put a T in. That line goes to a box with 4 quick disconnect connectors that the loader hoses tie to. Return goes to the filter cover. If one of those quick disconnect couplers failed, would it shut down the 3 point as well?Ē

I believe/ would guess there is a valve in the box where the quick disconnects tie in to. The box Iím referring to came with the JD 148 loader I purchased used and is where the hydraulic lines that go to the loader connect. My tractor is about 1.5 hours away so I will have to check this thought next time I go down.

Wore out, I think he answered your question on the loader supply in this reply. I think that is a common location to tie in to hydraulic supply on those tractors. The problem I have is I have not been around one of these tractors for 20 years so I cannot answer anything with a lot of certainty. I do agree he should have some one give him a definite answer before he messes with the pump. I really feel like if he posts this on the JD board he may get more responses.

Lumber, 3010 and 4010 do NOT have an "accumulator" for the steering and brakes.

With pump failure, steering works, to a point, with oil trapped in the system, brakes work manually, as brake valve reverts to being sort of a manually operated master cylinder.

That happen to my 4010 years ago. It was a piece of debris it the destroke valve on the bottom of the main pump. Likely a piece of packing from the loader. It never happened again. The system has an accumulator for steering and brakes to safely control the tractor and stop in the event the main pump stops working.

If you have good, full-power power steering, the pump coupler isn't the problem.

I was of the understanding the power steering doesnít work off the pump but rather from the reservoir which I would assume has some smaller pump or something for it? I may be completely wrong on that assumption but I read it somewhere in one of these forums. A lot of what Iíve read said in most cases, it isnít the pump in these old tractors but some valve that has clogged or the spring in the valve has gotten weak.

3010 power steering IS powered by the main hydraulic pump.

If the front pump were to quit you have LIMITED and POOR manual steering from oil trapped in the system. For a couple of turns. There's no other engine-driven pump for power steering.

Hmmm... thatís good to know. Scratching my head now! So something is killing the pump to 3 point and loader. Only thing I know of is de-stroke, stroke control valve or priority valve. Another thing that Iím pondering is the morning it happened, I scooped up a big load of gravel and took it/ dumped it and was going to back drag it with loader but it wouldnít respond except to go down. Flipped around to use box blade and same thing. Would go down but not up. No squeals/ chatter or any negative sounds from machine or anything. The plot thickens!

Have you looked at the pump from the top, and can you see the area where a top destroke valve would be located?

If pump pressure drops below 1800? psi the priority valve is supposed to close off oil flow other than to steering and brakes to "save" the operation of those vital safety functions.

Low pump pressure COULD cause your issue. In my experience it would be RARE for the priority valve to fail in a manner that would cause loss of flow other than to steering and brakes, of course strange things can happen.

By any chance, is there a quick-disconnect hydraulic coupler (or two) between the tractor and the loader? They can fail to open when connected and cause problems like this.

How is the loader connected to the tractor hydraulics, and does the loader have it's own valve(s)?

There is a steel cover over the top of the pump (under the propane tank) with about a 2Ē hole in it right over the top of the hex headed bolt which it directly above the screw on the bottom of the pump. I figured if the bottom screw was the de-stroke, you probably go in through that top hex bolt to adjust pressure??

The loader supply is tied in to the line right in front of the brake pedal on the right side... there was a 90 there and I put a T in. That line goes to a box with 4 quick disconnect connectors that the loader hoses tie to. Return goes to the filter cover. If one of those quick disconnect couplers failed, would it shut down the 3 point as well?

You have the pressure regulator and desroke locations swapped. The destroke valve is on the top and I am not sure but maybe the propane option may make it more difficult to access. See AgTalk link. I donít think a failing coupler would make the 3 point quit. Pull the hoses out of one of the regular SCVs start the tractor and move the lever either direction, if the tractor does not pull down a little and change sound from the pump you are not holding the closed center line pressure. Which it sounds very likely. I would post this on the John Deere topic section here and hopefully you get a reply from TimS there. He is an absolute guru on Older Deeres.

Thank you for your reply! If the screw on the bottom is the pressure regulator (which Iím thinking it is) it does not have a destroke in the hole directly above it on top of the pump. I can feel through the hole in the cover plate and itís just a bolt head. If thatís the case, can I just remove that bolt and screw in a destroke valve? There are no hoses in the remote scvís. The 3 point is tied in direct.

Do you know if I can post this entire series of posts on the JD forum?

Yes, in a way. I only know how to post a link to this discussion but it should do the same thing. They just might reply here instead of there when they open the link. And doing it in Classic View is the least complicated to explain so first switch to Classic. When you open your discussion topic in Tractor Talk copy the address bar in your browser. Navigate to the JD section and create your post in the Comments box then go to the box below it that is called Optional URL link and paste the earlier copied address in that box. Then go to the next box down to name your link and put..1st post on topic in Tractor Talk. If you know how to work in multiple tabs in your browser you can easily copy your intro post ..meaning 1st explanation you wrote.. from Tractor Talk into the post there and end it with copied from first post or the like.

Report to Moderator Re: John Deere 3010 Hydraulic De-stroke in reply to Rick3, 06-22-2020 19:00:46 I didn't go back and check the last post, but I would put a gauge in one of the remote couplers and check pressure, and then adjust the pump with the an allan wrench. Loosen the jam nut with a 3/4 wrench then slowly turn in the screw with allan wrench. Will need to hold lever to get pressure the the gauge. Had one similar to this, friend talked to the CSR man at the local Deere dealer, a car mechanic that didn't work with tractors much, anyway he told friend to check priority valve under the cowl/hood since he lost the hydraulics like you did, I chucked and he demanded me to look at it, so I did and found nothing, showed him the parts. So we put that back together and said lets try my fix. Did what i told you to do, hydraulics came back and was done. All I said was easy wasn't it.

Report to Moderator Re: John Deere 3010 Hydraulic De-stroke in reply to matthies, 06-22-2020 20:40:34 I guess Iím hard headed and couldnít get it through my head that was not a destroke until Tom posted last night. Just couldnít figure out why the book showed it as a destroke BUT I was laying there in bed last night and thought ďwhatís it going to hurt to try screwing it in (with gauges) and see if it does anything?Ē... then your post just confirmed my thought! I wonít be back at tractor for a couple/ maybe few days but will definitely check that and report back. Thank you for the response! Iíll let yíall know the outcome.

Another thought is disconnect the loader. You may have to plug the hose on the loader end because the tee you connect to the tractor on has a special fitting which may be hard to find a cap for. Now see if your tractor 3 point works without the loader connected. If so the relief valve in the loader valve may be stuck open. I believe you are connected as a power beyond circuit and closed center system is just circulating all the flow and pressure through the valve to the return. Another slim, slim possibility is that the loader valve is the type that can be switched from open to closed center by installing a plug inside one of the ports. If the plug was installed only loosely it may have turned itself out. Also to clarify in my other post the ..coupler.. I am referring to is a hose coupler not the drive coupler.

Are You sure the pump is turning? There has been more than one coupler between pump and engine that lost the splines. All may look good but the pump shaft does not turn when engine is running. easy to diagnose if it is that!
Good Luck,
Andy

DEERE made different versions of the pumps, "original" and "serial numbered" replacements, plus some other variations, with control valve components in different locations. The photo in the manual is taken from below, the original pumps had the destroker underneath

If what you are looking at is an Allen head, I don't think it's the destroker. As I recall, some pumps didn't have one at all but it could be added.

If a "serial numbered" or possibly other newer replacement pump the destroker or the port where it can be added is on top of the control valve body, as I recall.

HOPEFULLY someone with a bit more experience than I with the older-series pumps can confirm this.

Here's a drawing of a serial numbered/later pump with destroker screw on top.

Thank you for your response. I thought the pic in manual was from bottom but wasnít sure. I also wondered if maybe that was the de-stroke screw that had been worn off and meant to check before I left to see if it had a Allen head or not. I looked with a flashlight yesterday and it appeared it might have a slot. I assumed it was the original pump as it doesnít look like itís ever been replaced. I just didnít want to go turning it thinking it was de-stroke and realize it was the pressure adjustment screw. I checked the pressure at the loader yesterday and didnít get anything. Didnít have the right fitting on my gauge for the remotes at rear. The only other thing I know to check is the priority valve... donít know how to check it but need to find out. My power steering/ brakes/ transmission work fine.
