Answer to: 35mm plastic gearwheel broken bearingSearched online for a spare duplexer / rear cover for this printer, relieved to say I did not find one. Found that a 6BA bolt will go through the broken bearing spur, so drilled the duplexer frame 2.5mm and put the spur in a horizontal bench drill as a lathe, put a 2mm drill bit through using this also to take it out to 2.3mm, just holding the drill bit in my fingers. Remove bottom gear with one screw, fit spur with bolt from back onto frame, take some spare grease from the printer mech somewhere for the spur, fit middle gear and nut on with some metal glue (prob not needed). Bottom gear back on, works a treat.
