'68 318 to carbed Magnum 5.2: Check my checklist

A bit ticked today.

I swapped the main shaft bushing in the Saginaw pump with my hydraulic press, no problems at all:



However, the shaft, when reinserted, hardly spins at all without the pump pulley installed. And even then, it's a chore and a half.

I started to suspect the metric nonsense - or my installation - so I ripped apart a spare SAE Saginaw pump from my '78 Lincoln and swapped shafts on each pump. Not only was the '78 shaft tight in the new-bushing '89 pump, the '89 shaft bound tight in the '78 pump.

Is there some special trick to seating these that is escaping me?
