Engine sprocket install, how much of a gap?

Take a look at the photo below, I have ~1.7mm between the sprocket and the crankshaft shoulder. Not sure if this is too much or not. Please let me know!

This thing was a BEAR to get off, so I'm wondering if I need to heat the sprocket up in the oven to allow it to "slip" onto the shaft a little further. I heated up the sprocket with a propane torch and gave it bunch of swings with my 3 lb deadblow. What you see is the result after all of this.

Thanks for your help!!!!

That looks normal. Just torque the nut for the stator and it will be good and tight again next time you go to remove it. Jim
