My 22370 fan was slow starting, but got to normal speed after about 10 minutes. Lifting the blades seemed stiff which made me think it needed oil, so I added ND 10w. I quit at 30cc (1 FL oz), which is supposed to be the max according to the 1980 manual. I have to use >1" of pipe cleaner to detect oil, but adding more results in oil on the rotor & coil. Should I accept that as okay? It turns at speed immediately, although I haven't mounted the blades yet. Where is the overflow coming from?

The overflow is collected at a cup near the rotor. The fan itself uses an "Oil Bath" lubrication system which circulates the oil you put into the hole marked 'OIL' at the top of the motor near where the down rod goes into throughout the entire motor. As long as the pipe cleaner touches the oil, you should've put an adequate amount of oil into the motor.

Wonderful! I was hoping that would be the case, because each 3cc I add seems to cause some dripping from the brass plated cover, and that drips on the floor.
Thanks for your help.

Reviving an old thread... The fan is again starting very slowly, and when turned by hand feels like the oil had turned to sludge. When it gets turning at normal speed, the fan is running hot. Is it possible that the oil needs to be flushed out? If so, must the fan be taken apart to do this? Or can it just be taken down and flushed with mineral spirits to clean out the old oil?

Yes, I would recommend taking apart the fan to clean out the oil. I can only assume that if it was not cleaned out of years some gunk would've gotten caught up in the oil cup and shaft. Taking apart these fans is very easy. Here is a great video on the process, which works on most 80s originals. I would clean the shaft, rotor and oil cup with soap and water, make sure it doesn't get into the wiring and stator. You COULD Try the mineral thingy to clean it out, but that is experimentation that could cost your fan, might as well not risk it unless you are willing to report the results to us lol. Either way you will need to take out the oil cup which means disassembling the fan. I'd just go with a full cleanup. Goodluck and tell us how it goes! |

Thanks. You will see in another post that I tried flushing the system with WD-40 and adding new oil. It now starts at good speed, but it runs too hot to hold your hand on it for more than a few seconds. I was thinking that reinstalling the blades might offer some cooling, but your suggestion is probably the right way to solve this problem.

Just watched the video and it's clear that I have to do this disassembly and cleaning.
I'll obviously need to set aside an hour or two to do this, but I will report back when it's done. Thanks again for the suggestion and the video; I would not have attempted that job without it.

Personally, I would hang the fan, with blades, and fill it with WD40 until it is leaking out the bottom. Run the fan for a while.
Eventually the WD40 will be gone, replace it until it is clean, then replace it with oil.
I helped a restaurant that had 3 Originals that were completely stopped up. I wasnt able to take the fans off the ceiling. This solution worked.
Hot is normal, especially without blades.
WD40 IS mineral spirits with a penetrant.

I was wondering whether running it without the blades was perhaps the reason for it running so hot. I think I will hang in my garage/workshop and see how it works before disassembling.

I tried your solution before disassembling the fan to clean out the old oil and it worked. It's now hanging over my wood lathe in the garage and runs cool with the fan blades installed.

The oil reservoir holds just under 2 ounces.
