I just tore down the New Departure D hub from my 53 Huffy for the second time. I've not had it on the bike yet, but it was making a bunch of noise. This is the version with steel-on-steel discs, and they really howl!
But forget about that (for the moment anyway). There is a ratcheting noise when the wheel is spinning. I've been closely inspecting the drive screw and the drive clutch because I thought one of them was probably bent, as unlikely as that seems.
It turns out the hub has serrations on the inside where the drive clutch contacts it. The drive clutch also serrations, like all the drive clutches I have seen before. When the wheel is free spinning (not drive, not brake), the serrations inside the hub bounce over the serrations on the drive clutch and it makes a bunch of noise.
I have another hub here, so I disassembled it and tried the drive clutch from it in the Huffy's hub. Loud. Then I tried the Huffy's drive clutch in the other hub. Quiet. It seems the trouble must be the surface inside the Huffy's hub, and It must have been made this way?
The hub is from 1953, and has steel-on-steel discs. It is stamped and has an oiler, but is not high polish chrome or nickel. Maybe cad or zinc plated, maybe Korean War chrome.
Has anyone run into this?
