old freewheel hub/axle set up
I should know this but my brother brings me his old 1980's freewheel over to repair the tube. He managed to also remover the axle from the hub unscrewing it and the ball bearings dropped out. Well I did not see him take it apart and manage to get the ball bearings back in and the question I have is the use of the ball bearings. The wheel spins on the axle set in the dropouts but the ball bearings do not really spin as such right? I see as I set the cone nut back on and tighten it against the bearings but nothing spins as far as the bearings themselves correct? This is different that the front hub where the wheel sit on the axle and spins around the axle correct? I am probably not making any sense but just wondered. I do not do much hub maintenance as I all my hubs are sealed bearings and never have required anything.
