    What exactly did you check on the linkage.? Questions: 1. Do you have at least 2 pressure gauges capable of measuring up to around 500psi.? 2. Do you have a service manual.? If not what is the machine Serial Number.? 3. What type and grade of oil are you using in the transmission.

    sounds like low pump pressure and old mechanical saftey is pushing it out of gear

    Air leak in the pump suction line maybe.?

    possible need to check screen for beeing plugged and replace seal on cover they get hard and crack then check pump pressure

    Yes Yes 66A.09590 I dont know i just bought the dozer oil looks pretty good on the dipstick I ran it for 25 hirs with no problems but now i got this problem

    If the linkage pushes on the transpissin lever

  7. #7svenswiss2025-01-15 12:03

    I Will check the screen first

    The savety must be inside the gearbox I cant push the lever in gear mavbe something inside is stuck i dont know how this transmission word i think you push e valve with the lever that allows flud to do the shifting

    While you are checking the screen it ough tto be a fairly simple thing to check the transmission pump suction lines and connections. Kill two birds with one stone so to speak. Correct. It is inside the transmission and in simple terms pushes the linkage into the neutral position if pressure is lost.

    If I remember right pump pressure tap is on top of the transmission pump

  11. #11svenswiss2025-01-15 12:18

    So without pressue i cant put it in gear Where can i easy check the pressure?(hook up the gauge) if cleening the screen doesnt work

  12. #12Nige2025-01-15 12:26

    Just a thought. Is the transmission oil level correct.? How are you measuring the level.? Are you operating the tractor on any significant slopes.?

  13. #13svenswiss2025-01-15 12:54

    Yes Low idle, neutral No

    Seen suction line collapse

    Some times they lose prime, bad pump, restriction, low on oil etc etc.
