Graham: The pulley was on tight with no apparent misalignment. All seals, spacers, and bearings were new and in the proper order. The bearings and shaft reassembled into he pump housing without problem. Everything looked and felt correct. That is why I am puzzled.

Did you verify that the pulley was properly aligned with the drive pulley? If something was off there (maybe a spacer on the shaft in the wrong place, for example) it would put an offset load on the pulley.
