Can I "lube" my blower motors?

[StrangeRanger]

My exhaust blower on my Classic Cast from Breckwell is making noise. Can I use some bearing lube or something on it?
Thanks,

Most recommend something like 3 - in-1, or sewing machine oil, if there are oil ports. Your manual should say.

Some models have distribution blowers that require "lube" once or twice a year and others are sealed and "maintenance free."
Owners manual will tell you for sure. If you have motors that are maintenance free, and you decide "ah...what the hell could it hurt" if I throw a little oil in there, probably wont hurt, but probably wont really help either.
As for your exhaust blower.... if it is making noise, it's probably more likely from a carbon build-up on the fan and/or fins than it is a lack of lube.

Rattling sounds might be a loose bearing holder. The end plates of motors are often held in place by dimples in the motor shell. These dimples can be tightened with a hammer and a nail set.
Squeaky noises are usually worn or dry bearings

If it really is a bearing noise, my experience with motors is that if the bearings are making a squeaky noise it is too late. Oil will quiet the bearings for a while, but the problem will keep coming back. Time to think new bearings or new motor.

Even if the blower doesn't have lube points. Use a long tube to dribble some oil on the bearings as best you can. Most of these bearings are shielded(not sealed) so oil will wick in to them. It may not last as Harvey stated, but it will get you thru until the new bearings-motor-blower arrives.
