Extractor Fan Lubrication.

Zoomup:

This person has dismantled the motor to lubricate the bearings. The bearings are just a phosphor bronze sleeve with no balls or rollers. The light oil is good. A light mineral or synthetic machine oil is best. Some bearings have oil retaining felt pads to retain oil and slowly release it to the bearing, so quire a lot of oil will be absorbed by the felt pads when re-oiling them. This regular lubrication will be dependent on motor use and temperature of operation, but annually is good as the mineral oil can evaporate or dry out over time. If lubricated regularly a motor can last for many years.

The use of pliers on nuts is NOT recommended as it can damage them. The use of the correct sized spanner or socket is better. Do not overtighten the nuts.

A squirt of WD40 every few years has kept the fan going on my boiler for over twenty five years, including an emergency application from a borrowed can at eleven o'clock one evening after it stopped working.

Sad to say but another idiots guide from the master. I used to not be an injineer, now I is one.

"Tribology" from the greek word Tribo, the science of rubbing, well that puts anyone's mind in overdrive.

Possibly the WD40 just thinned any existing dried out oil or grease and made it serviceable again.


My can of WD40 states that it: Stops squeaks, Drives out moisture, Cleans and protects, Loosens rusted parts and frees sticky mechanisms. It is definitely a very thin penetrating liquid. The label does not mention lubrication at all.
