Can we see a better picture please - and perhaps more description?

Closeups are nice and all, but that one's too close.

Are we looking at the drive side fixed cup? Why do you call it a retaining ring? Might it just be a spacer?

Perhaps you should remove the cranks, and the adjustable cup, and the BB spindle, and then show us what's left? The problem might become easier when we (you and us) can see the face of the cup.

First off, take the crank off.

Then take a picture of the cup from the side - if it isn't obvious how it comes off. There should be either holes for a pin-spanner or flats for a ring-spanner.

And it'll almost certainly be left-hand thread.

p.s. that looks like quite a nice Fuji - if you have a good local bike shop you should take it there if you are unable.

Is that ring welded in place?

I wonder if someone didn't' face the shell too far and tack welded a spacer on there to get it back to spec.

What I thought. Looks like a tack weld.

Adjustable cup used as a fixed cup with ring tack welded to frame? There's a good chance the ring is welded to the cup also. As others have said, remove the crank so we can get a better idea what's going on here. Pull off the cup from the non-drive side while you're at it. Remove the spindle and the balls. This will give you a chance to evaluate the condition of the race on the cup in question and decide whether you want to follow the advice implied by [MENTION=493684]SurferRosa[/MENTION] and just leave the cup in place rather than grinding off tack welds.

The clip is just a washer, notched into the frame so it doesn’t rotate. I’ve seen these on similar old fujis. If I recall, some have a fixed cup that needs to be removed with a lockring tool (or punch), similar to the lockring on the adjustable side, but removing the crankarm should give you a good look for whatever tool surface the cup has.

The bb came off easy. But no can’t seem to get the washer to align when the adjustable cup is properly tightened

The thin washer is just to hold the adjustable cup in position when the lock ring is tightened. Most bikes don't use one, so I wonder if it was something invented to speed up production assembly versus wrestling two wrenches to set the bearing adjustment. You could hammer the washer flat on an anvil and flip it over to make the stake in a new spot. Or you could leave it out altogether.

thanks for the response. I can leave off without consequence? Thanks again!👍
