So there's actually three parts of my bearing that I found to be broken (rear wheel coaster brake). The bearing itself snapped 3 pieces which resulted in the balls and shrapnel flying everywhere inside the hub, but I got a replacement at the bike shop today. But there's also two other things broken:
- The cone-shaped nut that the brake arm supports is all chipped up where the bearing rides along
- The outer cap that goes right underneath the brake arm is cracked where it overlaps the outside of the hub. Kind of like a staircase-shaped washer.
If you don't know what I'm talking about, I included the attached picture for reference. What are the technical names for these parts, and where can I find them?
The guy at the bike shop (kinda old guy, didn't speak much English) wasn't able to tell me. I'd hate to have to part with a perfectly good hub for 2 items that are worth about 5 bucks.
EDIT: The reason for all this is that I must have not shaved enough off the inner part of the sprocket, as it does make contact with the outer cap. I think that cracked, which made the bearing somehow get loose, brake apart, and the shrapnel from that cut up the cone-shaped nut. I rode it for probably +300 miles this way. Seemed fine, just made a lot of noise.
