Zoomup
Would you lubricate a fan motor this way?

    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.

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

    Jaymack,

                    my comments are aimed at students and those who may not be "hands on" in their work. The subject shows how maintenance can extend the life of electrical motors in this modern throw away world. Some readers may be unfamiliar with correct procedures, so to assist them the correct ways can be indicated. My posts are meant to be educational, helpful and fun. Using pliers on nuts can round off the corners which is not good.
