Purpose of this?

[djohns]

On my ‘64 CA77 swingarm just behind the pivot tube, on the spreader with the plugs, there is a small bracket facing down with a nut welded to it. Does anyone know it’s purpose? For shipping? Just curious.

Good question!

There is nothing attached to mine either, and the parts diagram shows nothing I can find.

That is the torque arm mount for the rear brake backing plate, or panel, as they call it.

No, you can see the torques arm still fitted in the pic.

Apologies. Totally missed your annotation in the pix.

Have a local friend with a similar bike. Will ask if his has it, and/or if he knows.

Asked a local friend , and he replied:

"I had to go look as I didn’t even think mine had it but I indeed do have it and there’s nothing installed in it. Looked back at the pictures I took before I completely disassembled it for rebuild and there was nothing attached pre-rebuild either. It’s a mystery to me!"

Sorry we couldn't be of any help.

Those two tabs, facing downward, mount the bottom half of the chain guard.
