340 timing chain sprocket removal help

Hi gang..

I am tearing down my '70 340 and come to a point where I must ask you folks, the experts, a question. It seems the cam sprocket its not coming off the shaft as easy as i think it should. The motor is original and has 126000 miles on it.
Is there a trick to removing the stubborn sprocket? The bolt is removed and I have saturated the shaft with WD-40. What do you think?
