Flanged Bushing for Featherweight Handwheel
This flanged bushing is attached to the top shaft and supports the Featherweight handwheel. They are cast steel and can crack if the machine is dropped onto the handwheel, causing the handwheel to wobble.
This is an original used Singer part, and includes the attachment screw.
You will probably need a handwheel bushing puller to remove it. Click here for that tool: Bushing Puller
