Well......That's my junker crank I will experiment on.
It is NOT recommended but I used an aluminum wedge and a and worked around the bearing until it popped off taking the gear (on one side) and the cam chain drive (on the other side) with it.
I'll take this crank apart first to learn what NOT to do before taking my good one apart. Then I will reassemble the old crank parts and indicate it in true first, again...to learn what NOT to do.
