For fear of getting water in the motor i would not use that method versus a $50 puller, and on our clutches there's no need for a puller which is why i said no. ontop of that you'll need to find a longer bolt, a tube for the bolt to go through that won't leak water past the bolt and the quad will need to be tilted on its side which takes me back to my first point of, just go buy a puller.
and yes there is oil there.
