There are no bearings in the motor, the spindle sits in a hole in the bakelite casing at both ends. They don't need lubing. Cleaning the contacts and replacing the brushes are the only reason you need to disasemble a motor. On older motors, the 2 metal grease tubes were located on top of the round part at each end of the motor. The motors are of the exact same design, so not sure why they got rid of the tubes unless they realized they just weren't needed.
