Took the MG out this AM for a breakfast with pals. On the return trip, a really pronounced "buzzing" began coming from the engine compartment, could be felt in the shifter. I was less than a mile from the hovel, no overheating, no smoke from anything so pressed on to the driveway. No ignition light but my voltmeter dropped down to less than 10V!! Bonnet up, the buzz was coming from the generator. Front bearing rattling. The engine temp was normal but too hot for my delicate digits, so it was left to sit for about an hour while I scrounged around for a new bearing... found one in the top of my toolbox!
Out with the genny, benched and disassembled it. Bearing had rattled itself to the point it puked its lubricant, contaminating the commutator and the brushes weren't making contact thru the resultant coat of goo. Replaced the bearing, cleaned the comm & brushes with some brake cleaner, gave the comm a polish with some 600 grit wet-or-dry, reassembled and reinstalled. No more rattle and a 14V output!
Great thing about owning these cars since the late '60's is the "collection" of spares over the years comes in handy now and then. ...and folks just think I'm a pack-rat. HA! :wink:
