Rear hub seized, can’t get to cush drive.

(1/3) > >>

SteveW:
Just removed rear wheel to strip the hub as I’m putting new rims on.
Can’t remove the rear sprocket assembly, it’s as if the cush drive is welded to the hub.

Tried with a piece of wood across the wheel and a crow bar under the sprocket, you can see it move a tiny fraction of a mm but won’t come apart. Tried heat, WD40, nothing will shift it.

Taken many hubs apart over the years, never come across this.

Any ideas? 74 550 K0.

TezzerTel:
If in doubt give it a clout

If your not sure give it some more 😂

I take it you’ve got the retainer ring removed Steve?

SteveW:
No, retainer ring is still fitted.
Just realised that might be the culprit. On every bike I’ve ever worked on they just pull apart.

Is the retaining ring a left handed thread?

TezzerTel:
My one was a left hand thread. It came out the opposite way to the arrow on it. I thought the arrow would be the way it came out
