  • If you have problems with one way bearing on the Ober Winch in freezing temperatures you need to read how to change lubricant. If you are using the winch in +45C you leave it.. Drum is tightened with a 6mm umbrako 165mm in Read HERE

  • To adjust your winch you need either Manganin or Constantan resistor ("Kanthal" often called). Ober has a nice one to put on your battery (then you can have two equal batteries)


  •  How to... line:
