Those who have had myriads apart can best comment on the typical fit, but all have been off several times and likely acquired bumps and burrs, and others have been loose..
Bores have a tolerance range and modern extends very slightly smaller than previous and .0001 makes a difference. Is there any sign of repair; welding etc? It is important that it seats square, especially if a neat fit. If no scores burrs bruises, gently drive it on, greased. Whilst it is not vital (or even desirable?) that the rear bearing is a tight fit in housing, it does assist sealing. The steel felt retainer must be retained to ensure significant end movement does not develop
