Thanks again TGL.

I did not rotate the shaft in the pump. I did pull 
off the sleeve that covers the gear on the end of 
the shaft to inspect the o-ring for damage. There 
was no alignment mark on that sleeve but there was 
one on the pump shaft or a gear and on the pump 
body and they were NOT aligned. As I just wrote, I 
did not rotate the pump axle, so it went back into 
same place in the car engine that it came out of. 
I doubt that it would be physically possible to 
rotate the pump by hand. Of course the car engine 
did not rotate either.

There is a small section in the manuals about that 
alignment - the engine crankshaft is rotated to a 
certain angle and then the mark on the pump gear 
or axle is aligned with a mark on its body. 
Finally, they are "mated."   :-)   This 
description was intended for REPLACEMENT pumps.
