Sprocket must be just fit to shaft. If loose it will pull on and try break pin twice every revolution. Sprocket is likely wore the worst but shaft must be good also. loctite may make up the difference while using new sprocket. It is not meant to be a shear point. We have used taper lock and sprocket from 2 series machine on somewhat worn shaft. I'm betting top shaft beings you replaced auger and the way you are describing so I think it best to just replace shaft while replacing sprocket. Good luck
