16) Pull out the process kit forward and cover the drum with paper to shade the light.
17) Pull out and remove the transmission shaft from the backside of the machine.
18) Clean the inner circumference of the bearing, which came into contact with the transmission shaft, with an alcohol-moistened
cloth to remove chips and old grease. The bearings to be cleaned are located in 3 places: inside the drum drive assembly [a],
the backside of the machine [b] and the front side of the machine [c].
After cleaning, apply super lube grease (approximately 20mg, as much as a grain of rice) to the entire surface of the inner
circumference of each bearing.
