GE fan disassembly
Not off hand but these oscillating fans are fairly easy to disassemble. The biggest thing is getting that rubber hubbed blade off. I usually put some oil or WD-40 behind the blade and let it seep in and loosen up between the shaft and grommet.
Push gently from behind the blade and work the grommet and blade off.
With the blade off, you'll see 3 screws holding the blade guard to the front of the motor. Take those off to remove.
Looking inside from the front of the the motor housing, there are two screws toward the back a bit, one on each side of the motor. The oscillator knob pulls straight up. Take off the switch ring and then the motor housing should come off.
On top of the motor there is a flat cover on the gearbox held on by a few screws. With that off you can clean out the old grease and add new. Also can add some oil to the bearings. There are grooved areas where the shaft passes through the bearings, to help distribute the oil.
The late ivory models with ABS plastic motor housing are a lot nicer as far as servicing because the screws are accessible from the back of the motor, so you don't have to remove the blade and cage to get inside.
