The fan is 48 inch Monty Ward, control is Leslie-Locke (with a box designating it's for a 48 inch fan). I began using a small space heater in the garage, and the fan seems to be running much better (without a heater, it wouldn't go at all on low speed). Do you think I'm hurting it by using it if it's not going as fast as it should?? It does seem to spin pretty freely by hand, and the high speed goes pretty fast, which is why this seems kinda wierd.

Run it for a while on fast, and then see how it performs at low. If it is just a cold issue, the motor will get hot from running on fast and low will work as it should.

If the bearings DO need replaced, how "easy" is it to do for a novice repair-man?

Thats where i would come in from experience. i was able to find local places around me. the bottom bearing is easy, i just used a battery terminal puller, and i was able to take it to a bearing shop so they could match up the size. but then again it all depends what kind of stores are in your area. i diddnt have any luck at home depot, lowes or sears to find these supplies though. you may have better luck at an ace hardware to find the puller tool. i found my puller at "Harbor freight tools", dunno if theres any of those by you though.

You wont find a bearing puller at a local hardware store or home center. Harbor Freight is around everywhere though.

But bearings are the opposite...they love heat (as long as it's not the kind caused by friction due to a lack of oil), but they hate cold. Not so. Heat will cause oil to deteriorate, thus creating the "Dry bearings" condition you mention. Motors that run at cooler temperatures have better bearing life. If you're talking about heat in excess of about 110-120 degrees--in other words, the kind of burn-your-hands heat that you get from having a poorly ventilated motor running at a high speed for a long time, then yes. But I was referring to the ambient temperature of the room...a normal room, between 70 and 85 degrees, is very fan friendly; a more extreme environment like an unheated garage in winter is fan un-friendly. And while you're right that really hot temperatures--again, those usually caused by the motor itself--will degenerate the oil with time, it's the lesser of two evils...cold environments make the oil/grease stiffer and so the fan glides less easily.

Motors always run much hotter than room temperature.
