    rayzorsharp, you seem to be someone that I can always count on.:rolleyes:
    My heater fan wil run quietly for about 10-15 minutes, then it squals, endlessly, until the next day that I drive it. Then it repeats the cycle.

    CaptainComet, thank you for the heads up!:thumbs2:

    Oh yea, I thought brass was supposed to be a self lubricating metal. Is'nt that what the bushings in the motor are made of. Maybe it's just the "FOUR DECADES" that it has already been used.:biglaugh:

    Oil-lite bearings are not just Brass bushings - they are sintered brass and bronze. (they are formed by pressing metal dust under high pressure) The pores in the metal are filled with lubricant and then felt washers are oil soaked and assembled with the bearing to keep it lubricated. After years of working the oil dries out and the bearing begins to wear. When there is enough wear for the shaft to wobble it does just that. As it turns it travels around the bearing instead of just rotating in it - that causes the squealing that you hear. By then the bearing is already worn out and there is nothing you can do to correct it. Some lube might stop the squeal for a short time but there is too much clearance for it to last for long.

    that is the engineering reason why it is best to replace the blower motor when it starts to squeal. Now - if you could get a new motor with oil cups (like they used to use on most of the motors you could oil it once or twice a year with a light mineral oil and it would last for a bit longer than the factory sealed units we buy today. Most would forget to lube the motor and it wouldn't last half as long as the sealed units do or they would over lube them and the motors would get oil soaked and burn up.
    I am ok with a motor that lasts 20 to 30 years before it is replaced.

    I change motors almost everyday, if they all lasted that long, I'd be like the Maytag man.
    It's a pretty common motor, for less than 30 bucks, buy a new one.

    Nothing lasts forever. :hmmm: That's why they make replacements. Get a new motor. If that's the original motor it has paid it's dues. Seems to be a no-brainer to me - Get a new motor!

    As always PaulS, thank you for your input and explanation, chime in anytime. It's always a pleasure to read your replies.:thumbs2:

    Dave, I had actually decided about 10 replies ago just to buy a new fan motor, but this post has turned into a little fun.:bouncy:
