Oh Great Guru's: I have acquired an #800-1 dynamotor, which is 28 vdc to 115 volts 800 cycles, which winds up to 8,000 rpm. It turns freely, but I am concerned that after 60 years the lubricants might be a bit dry, and the first run could damage the bearings at 8,000 rpm. Any suggestions for cleaning and high-speed lubrication? Richard Brunner, AA1P
