I have a late 50's series Sunbeam twin-blade electric lawn mower that I use regularly. The shaft bushing(s) on the left blade has worn out, and there's too much play for me to run it w/o ruining the machine.It appears that the belt-run cog inside the housing is the part that is supposed to come off of the shaft to get to the bushings, but instead of a cotter pin or other fastener holding the cog in place, it looks like a rolled metal pin that may have been pressed in place.How do I replace the shaft bushings so I can keep using this great vintage appliance!? I found a website that supplies parts for this model year, but no schematics or user manuals.Thanks!
