The side with exposed bearings runs in the cups. Sounds like you had it right.

Looking at the closeup photo it looks like the center of the cage is chewed up some so maybe that was the problem

Next time, put the cage with balls on the bare axle. That'll tell you which side goes where - if you have it the wrong way the balls will not touch the axle.

And they're supposed to.

You can watch RJ take 5 minutes to tell you.

Looks like I had it in right so my cages must have been bad or at least one of them

Balls face race.
Cage in cup.

Appears you installed backwards.

9-ball retainers generally have the open side facing into the cup. 11-ball retainers have the open side facing the cone on the spindle. It appears you had it backwards. Loose balls always work, so no compelling need to re-do anything at this point.

This is too much. Here's the Official Park Video. I've always done it this way. YMMV

This side of the cage was facing into the cup. This side faces into the BB towards the other set of bearings. Slide this onto the spindle...

This side was facing into the cone. Is this right or did I have it backwards? This side faces the Crank arm to the outside of the BB. Put the cup over this.

Agreed. Grease the fixed cup race, insert loose balls (I use magnetic screwdrivers) and use finger feel to bed bearings.
My old mechanic mentor always said you can't have too much grease on a traditional BB but it's dealers choice.

11 and 9 were different for me too

Robert, I had my 615 apart I think and with the 11 balls in the cage, it fit backwards compared to the 9 ball cage. It was a bit counterintuitive, but just dry fitting and spinning the spindle and cups in hand revealed it.

Loose are better than caged anyway.

When you put the loose balls in did you add the extra ball or two to fill the circumference? It requires more loose balls that it does with a caged unit.

Nope there wasn't enough space for an extra

This is the correct orientation of retained bearings in the cups. Remember this and you'll always get it right. From Vintage Campagnolo Super Record Bottom Bracket Review | Cycling Obsession

The OP has 11-ball retainers. That's a full complement; no additional balls can be fitted.
