Pilot bearing fit

[Russ/40]

I'm putting together a 39 transmission for my model A. I'm using a new input shaft, never fitted, and the pilot bearings i have (3 different ones ) will not slip on the pilot shaft. I have always made it a habit to use bushings instead of bearings and never had a problem. I anticipate a problem getting the shaft to fit the bearing when I try to put it all together. I cannot push the bearings on the pilot. Is this press fit correct?
