Anyone have the bearings for a back wheel with coaster breaks. This has broken twice in the past, and I do not know why. It messures 32mm accross, and the bearing is 5mm.
Bearing in rear wheel

I had to rob one for a new wheel that lasted about a week or two. I have no idea what happened to mine either but the holder was just a twisted mess. I found one but I would have just shoved a bunch of bearing in loose if I hadn't found one. I'm told loose is fine as long as they are the right size. Bikes shops, (spit) has them.
Ya, That was my next step put them in loose. Probably put an extra one or two to cover the distance of the missing holder thing. Wow, those are some good pictures, sure glad someone told me about Tinypic.com
that's strange the bike shop swears thats how they do it all the time. Does you cone not fit right. If so maybe that is why it was breaking the bearing holders.
I am going back to working on that in the morining, now I am back working on the bushing. I just need to take a break from that before I start working on it mad.
There are some pretty sorry hubs out there. You may want to check with your LBS on the price of a complete wheel with a Shimano hub. Try for heavier gauge stailnless spokes while your spending the money. How about JB weld....LOL.
Yes you can put the bearings in loose. It will take roughly twice as many balls as what are in the cage, dip each ball in a good quality high temp grease and it will help hold them in place until you are ready to reassemble the wheel. From what I can see it looks like your wheel was too tight and you basicly burned up the set that you took out, I've done this. If you don't wan't to go with the loose balls you should be able to get a new set from your LBS for a couple of bucks, make sure to get the right size, I would reccomend taking what you have left or the wheel with you...Kelly
I have overhauled probably hundreds of coaster brake hubs in my days; here are a few tips on overhauling/adjusting them.
Loose balls are very difficult in a coaster brake hub as the cup that the bearings sit in is very different from a typical hub, headset or bottom bracket. I highly recommend spending the whole dollar and replacing the retainer as well. Pack the bearing with grease until the grease is coming out the other side, then add more after the bearing is sitting in the cup. Don't put the bearing in backwards; that'll wreck the new bearing in a hurry.
Always do the hub adjustment from the drive side (with the cog). Leave the side with the brake arm alone (locknut tight against the brake arm). Even during the overhaul, there is no reason to loosen that locknut.
As with any hub adjustment, tighten the cone/locknut on the drive side only enough to take the play out of the axle. It's trial and error; 1/8 turn can be the difference between too loose and too tight.
You can almost never have too much grease in a coaster brake hub, kind of like you almost can't overcook a braut. The photo above looks to me like the hub was dirty and not enough grease.
Good Luck, Steve
