New Dimension Model 3

[wrenching4fun]

I'm rebuilding a vintage Firestone wheel with a New Dimension Model 3 hub, but cannot figure out how to remove the sprocket. As the attached photo shows, it doesn't have a c-shaped snap ring. Would appreciate info.

Loosen that collar. Could be left hand threads ?

Yup... That collar is reverse threaded.

Does the sprocket scew on also, like a skiptooth?......Curt
