  2. #2The Don2025-04-08 17:20

    If you take it out of high idle notch and run it into a pile will it try and stall the engine??

  5. #5The Don2025-04-08 17:35

    Is brake pedal stuck part way down ??

  11. #11The Don2025-04-08 18:15

    It was but we un stuck it and it's still doing the same thing

    There is a hole in brake leaver on top of transmission on the end cap of valve there is a threaded hole I believe it’s 5/16 don’t remember if it’s fine or course thread bolt must screw in when pedal is up if it doesn’t line up it will cause problems

  13. #13The Don2025-04-08 18:27

    We well try that tomorrow

  14. #14The Don2025-04-09 16:42

    Ok we we lined everything up together and put it back together and still no luck any ideas

  15. #15pittsburgh cat man2025-04-09 16:54

    You need to check a couple of pressures 41,43and42 you will need 600 lbs gauge check pressure at high idle in park

  16. #16pittsburgh cat man2025-04-09 16:57

    This will help

    We took off the top off the transmission and found 4 rubber small hoses 2 on each side that look bad and one of them definitely looks busted but how do we get to them on this 963 b ? Do you have any pics of what we have to start taking apart to be able to get down there to be able to put new ones in them?

    If you want to post a machine Serial Number it might be possible to get some parts diagrams. Also post a photo or two of those hoses to give a bit of an idea.

    I believe 9bl is your only choice

  20. #20Nige2025-04-11 16:58

    Good point. I was on auto pilot with the ask. Are we looking at the inside of the hydrostatic power case.?

  21. #21pittsburgh cat man2025-04-11 17:44

    Yes I believe he is looking for servo lines they will be part of 104 6210 lines group

  22. #22Nige2025-04-11 18:02

    Here they are.

  23. #23pittsburgh cat man2025-04-11 18:25

    I've been setting here thinking in all the years i can only changing one servo line in the tractor. on the side with the over ride valve(linkage from throttle connects to it) there is a baffle plate that is bolted in it might give you more access
