    coupler removal how to remove coupler engine coupler

    This is what I have done in the past......if you don't have a removal tool

    If the crank is in the motor:
    * I put some nylon rope in one of the cylinders
    * Used a beaker bear and a towel and place it inbetween the coupler fingers and take it off.
    * Ya might even need a little heat to expand the aluminum a tad and it will come loose.
    * When you reinstall, add a bit of antiseize on the threads so removal next time can be easy.

    * rope in the cylinder works good too for removing PTO's from older Sea-Doo engines.

    * If the crank is out of the motor, use the breaker bar step above.....and wrap the crank in a towel and place it in a vice.
    * If you don't haev a vice, wedge it under a tire.
    * Wrap that crank very well.

    I used the coupler removal tool to do mine bought it pretty cheap on ebay. When I had my crank out I used my vise and wrapped the crank with a rag held it in the vice and used a breaker bar with the tool in it. came off pretty easy. I have had others where a little heat was necessary on the coupler. I have seen a few couplers where guys used chain wrenches to remove it does scar them up a bit. I do not beleive it hurts anything just cosmetic.

    This puppy is really on there. Crank is outta ski and dont have a vice available right now so tried the under the tire trick but still couldnt keep it from not spinning when trying to really crank on it. I tried heating it up but that didnt help. Not reverse threads or anything like that right??? Well If I have to I will take it to work tomorrow and stick it in a vice and go at it.

    just to double check this thing isnt reversed threads right. Like if I had the crank sitting in front of me like it sits in the ski and I was looking to the front I would want to turn the coupler counter clockwise correct. Cause this damn this is really stuck on there.
