P-162-B Edison HOME and TRIUMPH (both Model D) Mandrel Shaft Bushing, NEW, to replace the old pot metal bushing in the Edison HOME and TRIUMPH cylinder phonograph. Same size bushing for both HOME and TRIUMPH. This item is referred to as "MAIN SHAFT BUSHING" and the original Edison's stock number is 2723. HINT: In the attempt to remove the bad pot metal bushing it is necessary to loosen (or remove) the small set screw that's half way up the tower that holds the bushing. This small set screw will have to be replaced and lightly tightened against the new brass bushing after the brass bushing is inserted and set correctly in that tower.
