Those GE unit bearing motors always sound nice starting. My refrigerator condenser fan has a nice sound evert time it starts since it uses a GE unit bearing motor.
For the 243 I would recommend just replacing the bearings. The older versions have grease cups on the back of the motor and those bearings are only shielded on one side (fafnir type 203KD for the rear and 204KD for the front)so it would be possible to clean out the old grease and replace it with new but you'll get better results if you just replace the bearings. The newer and more common versions have fully shielded bearings so for those I would recommend just replacing them. The bearing types for the motors not equipped with grease cups are 88503 for the rear and 88504 for the front. These bearings are not the most common types to find but you can substitute them with common 6203 and 6204 bearings, you'll just need to make some arbor spacers to make up for the difference in bearing widths. One last tip for these fans, from my experience with them I find that the motors tend to have a bit of end play so adding a preload wave springs will help it run smoother and quieter. Hope this info helps you out, if you have any other questions please don't hesitate to ask!
ILG fans were the best!

Kya rate hai
When were the 243s made?
Nice
I have a model 243. Do they require lubrication? If so what/how?

Noice
60Hz ?
Yes these fans are in the U.S.A. so they all are running on 60 Hz at 120 Volts.
