    This video was a life-saver. I was able to straighten my crank today!!

    When you said you were going to use a chisel on the crank, I thought for sure you'd be striking a counterweight and not the rod journal. Amazing process.

    this is great. would love to see one on cold straightening a propshaft. we normally send them
    out but would be better to be able to do in house.

    Great video, thank-you for demonstrating. Why do you only hit it on the left hand side of centre?

    Would 3 thousandths TIR cause binding on main bearings. Clearances seen ok

      Probably not. .003 bent isn’t huge. Maybe the main bores themselves are too tight or not in alignment?

    Nice job ,why do you not use hydraulic press?

      Peening stress relieves it. If you use a press it will spring right back like you never hit it.

      Where he hits it down, he's making it come up.

    How much do you charge to straighten a crank.

    • @LakelandAutoMarine
      @LakelandAutoMarine  Рік тому

      Depends on how bad it is and how far out it is. It’s time and materials.

      @@LakelandAutoMarine I read a article from caterpillar ,they say you should heat the crank to about 100 to 200graden Celsius before making it straight?
