Original Handwheel Washer (stop motion clamp washer) for all black, tan and many white Featherweights*. Washers with part number 45930 or 45716 are interchangeable. To remove the handwheel, you will need to unscrew the tiny screw on the stop-back motion knob first. Slip the new handwheel washer on with the notches facing out, then replace the hand wheel and stop-back motion knob.
*Some white Featherweights have a larger sized stop motion knob with a 9/16″ threaded post. (All black, tan and most white Featherweights have a 1/2″ threaded post.) This washer will only work if the threaded post measures 1/2″. Please contact us directly if you need a larger washer.
