    Main vavle stuck?

    JD 790 ELC Has been under water runs fine if you are just moving tracks but you cant run just one track it will kill engine. swing and bucket and boom will try to or sometimes kill engine. 6 line going to track control. If I take the 2 off that go to the hydraulic lock valve and loop them...

    JD 790 ELC lugging

    Water got above top of boom. I think there is a hydraulic issue maybe a valve is trying to go both directions at once. How does one test this?

    Timing a Deere 4045T engine

    Had injectors tested. Three were bad bought three new. It starts quick and blows black smoke. Revs up to maybe half throttle smoke clears up a bit. Doesn't surge just won't rev up. I got this as a basket case so not sure how it was before. I know I'm missing something. Just haven't found it...

    That's what I thought too that's why I lined it up on six. When there starts easy but when I first started it revved up for 5 minutes then stuck at half throttle. When I turn the pump it revs just a bit high like it's trying to get there. I guy in Tulsa that all dealerships know but pump. All...

    Timing a Deere 4045T engine

    One timing hole in flywheel. Sets engine at tdc on 1 then rotate 360 and engine will be on tdc on 6. Figured out has to be on 1 but when I line the gear up 6 mark to center of crank engine doesn't run right. So I moved pump gear one tooth toady and engine ran worse. On tdc pump has to be turned...

    Timing a Deere 4045T engine

    I have a 6068t. When I pin flywheel do I pin on 1 tdc or 6 tdc to time? I've pinned on one but engine won't rev up. Only maybe half throttle. Also #1 injector is wet when I pull it. Two marks on injection pump gear. 4 and 6. I've read it should have more. I have stanadyne db4 pump. Timed on...
