my 8 yr old son and I took apart an old beater bike, spray painted it and we are now putting it back together again.

I was trying to repack the bottom bracket (for a one-piece crank) and looks like I did it wrong, it was not fitting tightly and when I took it apart again the bearing retainer on the sprocket side was bent - the bearings fell out, etc.

I was looking online for some new bearing retainers to match the ones in the BB (9 bearings) but all the ones I found measure 1 1/4 inside and 1 7/8 outside. Mine is 1 1/2 inside diameter and 1 3/4 outside.

Any ideas would be very helpful.

Thanks!

P.S. I am not even sure what kind of bike it is, I think a Schwinn. It is single speed, foot brake.
