I just got done fixing the hub on the brown Raleigh Sports I picked up a couple weeks ago, the sun gear I took out of the hub was stripped the same way.
The bike had a repair tag on it saying it had a problem with the hub, I added some oil, pumped up the tires and took it for a ride. It rode fine till I really put some real pressure on it. It would skip a bit in third gear, make a snapping sound and then felt like it was binding up. Shifting to 2nd would fix it till I shifted into high again and stood on it.
When I opened it up the thing was full of bits of metal, about half the sun gear teeth were gone and one planet gear pin was broken but still in place.
I saved the gear but lost the pieces to the pin. I stripped down a hub from a junk bike and its been fine since.
The hub was dated 10-71.
The hub was a greasy mess, it leaked oil bad around the right bearing cup. The whole rear wheel and spokes were caked with old dirt and grease. When I put it back together I sealed the threads with some thread sealer.
