I have a-73 850 that I took apart a couple of years ago, so I don´t remember if the sprocket was hard to get off of the cam. Now I´m finally starting to put it back together with some upgrades and of course new bearings and all that. But... I tried the sprocket on the new cam and as I remember it should go pretty easy on there, but it won´t, it stops on the threads on the cam. Strangely it doesn´t slide on the old cam either, it goes past the threads but no longer, do I need to heat it when installing it? Or is there some other trick?
