Loose sprocket

Replacing sprockets on New Holland 195 spreader chain from bottom beater drives top beater.. inch and a 1.25" shaft ...slide sprocket on shaft and it's just a smidget loose not that it wobbles or anything and you cannot physically see wear , you can measure just a smidge it with the calipers and I'd like it that the Sprocket was like a driven on fit. I don't think we need this line bored accuracy, so I'm wondering what would your preferred method be to fix this something I could do in my shop tomorrow and not disassemble a lot and send it out to a machine shop
