Well, in my previous life as a journeyman industrial electrician, fixing motors was a normal part of the job. Especially silly things like this, just a bad bearing. Whip off the casing, knock out the pin or key, and pull the bearing with a pulley puller. Go to Stores, pick up a pair of new bearings (if I didn't have spares that particular size in my roll-away), slide them on, shove in a new pin or key, and put the housing back on. Test run the motor, and back into the machine. Or more likely, back on the shelf since we usually just swapped them out to keep the line running. (And the best part -- it wasn't even my job to pull the motor -- I just had to disconnect it from power. Pulling it was the millwright's job unless it was 1HP or less.)
IAC, it's out now and I'll take it down to the diesel shop on Friday. Meanwhile, however, a big glass of fresh squeezed orange juice, and a mug of Lapsang Souchong.
