    We had hydraulic problems with our 3040. Replaced the pressure relief spring. Found scoring in the low pressure pump and two valves damaged in the main pump. 100% now.

      I did indeed Tim. It gets regularly serviced and filter was as it should have been. Originally a few years back the filter was not changed by a previous owner and it eventually blocked up, collapsed and was sucked up through the system and ruined many parts on the way. Took a long time to get it all flushed out and cleared. We are in a better place now. Thanks for watching 👍🏻

    Running the remote valves like that is the quickest way to ruin the main pump. That juddering sound and the vibrating pipe is cavitation, because the transmission pump can't keep up. Anything you run off the remotes must be closed circuit plumbing.

      Yea 100 percent true and I agree fully, but this has been a problem a long time with it and if that’s a problem when all is done I will rebuild it too. The issue is with these old Deere’s and most machinery is that you must carry out as many tests as you can to make sure you have found every angle and possible issue before you open them up. They can be a nest of problems and serious money to repair certain parts on them. I had limited choices to be able to do the tests on the tractor since the transmission was damaged and the tractor was at risk of serious damage if it was driven around too much. Thanks for the comment, it’s a very knowledgeable, valued opinion and hope it helps others. Thanks again👍🏻

    Hello. I have a John Deere 3650 and I recently rebuilt the transmission. I changed discs, plates, o-rings, rubber rings from the hi low case, I also changed the pump in the transmission, I put a new one but it's on the aftermarket, I changed segments on the power take-off absolutely everything. I have problems with the steering and with the arms on the back, it is hard to lift and turns with knots. If I remove the cover from the gearbox and connect the two pipes between them with a hose, the steering works perfectly and with the arms on the back, when I put the cover on, the steering and the arms on the back no longer work. What could be the cause? Thank you!

      A major internal oil leak or a broken shaft to your internal oil pump. Even a very bad internal oil pump would still pump some oil up to the front reservoir. If you drive it you will end up with serious harm done to the hi Lo and everything else after that.

    Greetings from Romania!
    My John Deere 3040 started leaking very badly in front of the drive shaft who goes into the steering pump.
    It s very very bad ,until i got home it leaked over 30 litres.
    Is it a seal in the steering pump that popped?
    I searched on Deere parts,it looks like there is a needle bearing,an o ring and a seal,in this order from inside out of the pump.
    I was thinking of fixing it ourselves to save some money,i cant see anything else around that coupling that may leak.

      That’s your High pressure hydraulic pump that runs all of your main services, lift arms, remote valves, Steering and trailer brakes. Yes buy a rebuild kit but I would advise taking it off first and opening it to examine it. Sometimes parts break inside the pump and can leave it unrepairable. Goodluck!

If you take this out and take it to a local hydraulic company they should be able to find it for you. It’s small and possibly a metric fitting and a fine thread I think so it’s not very easy to find.

    • @connormcmahon3724
      @connormcmahon3724  2 ปีที่แล้ว +2

      Need to check to see if your 4wd Solonoid is working. It’s on the bottom of the tractor on the 4wd belly cover, protected by a small bracket. You can switch it on and go underneath and unplug the wire off it and tip it back on it while listening to it to see if it’s clicking.
      Then if your still in trouble you need to check the oil pressure from the small bung beside the solonoid. You could have a 4wd clutch pack worn out or needing resealed. After that the only thing that I could think of is the front axle. There are plates in the differential and they can slip if the wrong oil is put in them.
      Hope this helps and thanks for watching! 👍🏻

      Bonjour, it sounds like the scavanger pump or transmission low pressure pump in the botto. of the tractor is not pumping so you could have a problem with the pump. There also could be a major internal leak or a reason why the pump is not running. This could be a problem with the drive to the pump either. I would advise you test the pressure on the shift cover or even open the screw to see if oil comes out when you run the tractor. That will tell you if you need to open the tractor up.

    Great video! I've got a 2950 where the Hi no longer works. When you flip the shifter into Hi nothing happens except for a bad side affect in that you loose hydraulic pressure. The steering starts to fail, loader controls no longer work, etc. and the low pressure warning lamp comes on on the dash. Flip the shifter back to Lo and everything is fine. Any thoughts on what/where to dig into?

    • @connormcmahon3724
      @connormcmahon3724  2 ปีที่แล้ว

      So in Lo you still have all hydraulics? Sounds like a major leak internally, you either have blown seals in the hi lo pack or a leak from the shift cover I would replace all seals on the shift cover first and inspect it for cracks etc. That’s the one thing you can do before splitting the tractor. There also could be an internal metal pipe that has split or blown out. If you could check the pressure on the shift cover that will tell you if you are getting enough oil pressure on the low pressure side from the scavenger pump. It should maintain no less than 140psi when oil is up to temperature. Sometimes they can be difficult to diagnose and the only way is to test the circuits to see which one is loosing pressure. Goodluck

Check that one hasn’t popped off or something simple like that. Excessive wear on them generally can cause you to get stuck in a certain gear.
      Park the tractor safe so it won’t roll and get underneath her, get someone else in the cab to start moving the shifter to see where it’s connected and go from there.
      There can be a very rare case of them getting stuck in gear internally on the selectors should they come loose but start with the basics first. 👍🏼
