Just acquired my first fan, an Emerson 77646-SL. Can someone share how much grease goes in this vessel (not sure what else to call it, but I'm sure it has an official name). And should I remove this old grease before adding new? Thanks! Can't wait to clean this ol' beauty up!

Dig out as much old grease as you can, then cover the gears in new grease. You don't need to fill the oscillator box up.

It is called a gear box and put most of the grease on the gears that is where you want it but if you don't over fill it then you are find. If the fan slows down then you put to much and you will have to remove some. Another thing remove all of the the ild grease first before putting new grease in.

Zachary, I see John McComas recommends white lithium grease. Do you concur or do recommend something else?

Lucas red n tacky, or Valvolene general purpose wheel bearing grease ( not the high temp stuff for disc brakes) is what I use.

Vessel - love old-school the EU terminology!  :)
I've read the idea behind using Red & Tacky or Vaseline in the gear case of certain fans, and can't help but be concerned that I use Purple synthetic grease in my fans.  Is it that Red and Vaseline congeals (turns slightly wattery with use) and feeds the oiling hole better - because the synthetics simply don't break down and congeal like other greases?  I have to admit, some of these old fans I have run GREAT, even with the oldest 30+ year old grease in them.

Should I get away from Purple?

I've not found either of the 2 mentioned to break down, though oddly, I have had the purple grease separate and leave a gooey, oily mess where the tube was sitting. I like the Lucas because of the color...kidding. 

Truthfully any good quality grease is better than the animal fat based greased used in the old days. It's just a matter of preference. 


What I have found though is that some of these fans have run for so many years without useful grease and dry gears, that the gear wear and meshing is based on no grease. They run quietly that way and then you add grease, and they get noisy when oscillating. My theory is that after running for so long without grease, adding grease changes the tolerances and causes the gears to mesh slightly differently, causing the noise.

I dig out as much grease as I can then fill the cup with Krud Kutter solvent and let it sit over night. You can get Krud Kutter at any Ace Hardware store. It does a great job of liquifying the old grease which then comes clean with some super hot water. Then I use wheel bearing grease to cover the gears. You can get a tub of that at any auto parts store. Works great!
