Caged Bottom Bracket Bearings...

I'm almost done restoring an old Nishiki International. The bottom bracket was smooth before i took it apart. I used Finish Line bearing grease, and put a good amount in. After i tightened it up it seemed to have a roughness to it. If i let the spindle have some play it was smooth. Everything appeared to be in great shape during the cleaning. I know the retainers are in the right way as well...I suspect the retainers are the culprit tho. Should i just get new retainer bearings...or can i use loose bearings. And add a few to make up for the space of the retainer?

Yes you can do that. Take a bearing in to your LBS and get a bunch.

Same thing happened on my Schwinn Voyageur, turns out one of the bearing retainers bent (slightly) on install or adjustment. Throw out the bearings and cages, and get new bearings, and go loose ball. The adjustment was perfect after that, no resistance or anything. You will probably need 2 extra balls per side, but it is well worth it, huge difference.

I really can't see how the cages can be that effiecient anyways. I didn't like the idea of using em, but when i rode the bike prior it seemed alright so i figured i would. I bet if i wouldn't have dropped the cage it would of been alright, the bike was barely ridden. Ohh well, i get to work on my bike more, poor me

The other fun with cages is putting them back in - backwards. Go with the loose balls. 1/4" as stated. Regards a new chain, you likely will also need to get a new cassette/freewheel, too. The old cassette & chain rather "stretched and merged with each others shapes during normal wear. If you just install a new chain, it will likely skip on the old cassette.

Good luck!

Haha, i've done that a few times, you tend not to do it after the first few messups, lol.

Well, luckily the bike wasn't ridden much. It had a thick layer of dust on it when i rescued it from the trash and rode it later that day, and the only reason i'm replacing the chain is because i cleaned everything else, and didn't really feel like putting the time in to clean the chain as well as everything else. But there's very minimal wear. Sugino Crank and Suntour Freewheel is probably why they are still in good shape.
