am I right in thinking that the shaft and bearing press out forwards by pushing on the shaft centre of the impeller..? the shaft at the impeller end looks to be a smaller diameter.


I can't really figure out what you mean by this. Once you press off the pulley hub then you will have the body, bearing assembly, seal, and impeller as one assembly. You need to press the bearing assembly out of the body and in doing so the seal and impeller will stay attached to the bearing assembly. Then once those are separated from the body, you might be able to press the impeller off of the bearing shaft.

You will have to be extremely careful to use some sort of tool that only puts pressure on the brass insert of the impeller and distributes it evenly. The impeller is extremely brittle and I will honestly be surprised if this works without it breaking even doing it the most optimal way.

The manual has a cross section.packardinfo.com/xoops/html/downloads/ser ... ual5556/Sect14_Radiator_Cooling.pdf
