The pilot bearing is a standard metric bearing with a 17mm bore. The bearings will be sized to a very tight tolerance. If the input shaft does not slip in, as the input is new I would suspect it is not sized correctly. Do you have another shaft you could try the bearing on? Or do you have a means of measuring the shaft accurately?

I would agree with the suggestion above that the input could be polished. If you have access to a lathe the task would be much simplified.
