    skytrak 6036 weak tilt

    I Don't know what kind of temperature you deal with, but in Michigan I've seen ice crystals form on the suction screen in the hyd tank causing pump cavitation problems. Even changing the oil doesn't fix much because of all the old contaminated oil in the cylinders. Concerning the attachment...

    Kobelco pressure test

    I bet it's hooked up correctly. When you changed the tee fitting at the swing brake did you notice a small steel ball inside of that fitting? If it's missing your arm will come in every time you swing. Kobelco engineers release the swing brake when arming in in case of bank caveins. they keep...

    SkyTrak 6036 drive trouble

    If your serial# starts with 16000 or 1600 that's still a ZF transmission, I'd take a look, 30 min job. I've seen it many, many times, doing exactly what your talking abought. Easy check is to pull the dipstick first thing in the mourning before you start it, it should be abought 3 inch's over...

    Kobelco SK160LC throttle control

    If it's not to late don't remove the splined arm from the shaft, if it's been in the right spot for the last few years it's still in the right spot. How bout the shaft itself, is it loose in the housing? Ball joints not seized up, to loose? If you do have a good limit switch by willie's test...

    Kobelco SK160LC throttle control

    It sounds like the stepping motor is looking for the limit switch. Yes it is controlled by the main controller. You didn't mention any codes on the dash? To diagnose the problem you should do continuity test at the stepping motor, wire harness, and controller. You wont like hearing this but I...
