trim tilt pump assembly or drawings? where does the 3rd ball bearing go?

[Zberry1985]

this is a trim pump off a 1984-5, 45-50hp mariner 0A745967. the pump wouldn't spin so i took it apart and it seemed like where the motor shat goes in was mushroomed out enough to jam it, i sanded it down and got it spinning freely. i didn't see where that third ball bearing came from, anyone know? also not sure if there was a third spring for it? i circled where i think the most likely spot is for it.

rectangle style Eaton motor.
i know you shouldn't take these apart but I think it's worth trying.

I figured out the 1 of the balls is slightly larger and that's the one that goes in the circled hole..

Also I ran the pump in a bucket on the bench to make sure it worked, highly recommend. I figured out that I didn't have enough pressure on the check valves, only one would open. Tightened the bar across them a hair and it worked.
