Put the timing / crank sprocket back in

[tgsho]

I have searched, and tried heating the sprocket with a heat gun and a torch. I also tried putting some ice on the shaft to try cooling. I have searched and cant find any help with this. Can someone here try and help me put my crank sprocket back in... TIA
