  • Trouble dissasemble wrist pin

    I have problem getting out wrist pin out of the piston

    Its not available anymore, so I am afraid of breaking something. Is it right to just use a heavy press to force the pin out?

    On some older evinrude wrist pin removal you would use a half round fixture
    ( special tool ) to press out the pin. Inside the piston by the wrist pin was a L that ment loose side & you would press it through the tight side so you don't distort the piston. I've pressed them out without the fixture. You can try google vintage evinrude parts or maybe wisco pistons ?
