Federal Steering Pump Pulley Depth

64 Valiant slant 6. I have rebuilt a power steering pump for Vixen, but I do not know how far to press the pulley back on the pump. The service manual says to press it on until the shaft is flush with the outside of the bore on the pulley, but that is impossible with this pulley configuration. I would have to literally push the pulley thgouth the seal and into the pump housing. The book also shows another picture with the pulley installed and it is clear that the pulley is NOT flush with the end of the shaft. I have another Federal pump that I have yet to disassemble. I plan to rebuild that one, too. I took a measurement with a machinist's rule from the outside of the pulley bore to the end of the shaft and got 11/16". Does this sound right?
