    Does this have anything to do with prv silenoid

    Is it making any grinding, growling, or banging noises when you do swing? If not then it's likely you have a problem with the swing brake coming on....

    Try knackered swing box in the trouble shooting spot, as that is the most probable answer. tctractors

    No noise of any kind,it will just stop,then give it a min and will work again but only for a min or so

    No noise of any kind,it will just stop,then give it a min and will work again but only for a min or so what would cause brake to come on?

    Pretty new excavator for a swing box to go bad. You should probably check the oil in the swing reducer. If that is good you can check the switches through the monitor panel. A bad solenoid or relay should have tossed a fault code.

    Ok we have had a guy from cat come check this thing out and he has been there two days and found nothing,you can flip bypass switch and will work fine,without bypass switch flipped you have to work it for a bit before it locks up. Any ideas?

    Sounds like a faulty sensor somewhere giving the computer a false reading....

    change the little green switch on the front of the control valve

    Ok now is this a switch to be flipped or replaced

  13. #13mljohn2015-08-04 19:24
