Had a little time Friday to work on the 101. The goal to run parts through the ultrasonic; clean-up the painted surfaces with machine oil; clean out all old grease, oil, and dust.
Cleaning bearings of old grease, oil, and dust/grime. There are 4 locations on the 101: lower left front under the hook, lower right rear under the vertical shaft, upper back where motor is mounted, and top rear machine upper cam.
Next was disassembling the motor for cleaning: brushes, grease wicks, commutator, and motor bearing.
