A bit late on the reply here but I have recently discovered a lubrication
product that I am pretty impressed with. It is
http://www.laco.com/lubricants/zoom-spout-oiler/ I got a tip from a
Facebook group "vintage electric fans" which as you probably guessed deals
with working on a lot of old and very old electric motors. I bought a
container of it at my local ace hardware, which is an olde timey place with
lots of varied product. It was less than $5. This lube is advertised as
"turbine oil" which makes it sound very impressive. I have a few old and
not so old fans laying around. One is a typical cheap 3 speed stand fan,
probably 10-15 years old that was given to me because it stopped working.
I've taken it apart and cleaned and re-lubed the bearings several times. I
use it in my basement/shop and have been running it with the case off the
motor so I can monitor how hot it gets. I've lubed it with tri-flow or
sewing machine oil a couple times and it will run fine for about 10 hours
before the bearings start getting so hot it slows down on the high speed
and won't even start turning on the low speed. I have far surpassed that
performance using zoom spout. Another totally worn out blower for a
woodstove has showed the same results. that extendable spout may even
reach the vanagon front blower motor bearings through a Mullendore port.
