Bryant 394G Blower Motor - How do I lubricate this thing?
Our Bryant 394 started squealing something awful, so I hauled the blower motor out to lubricate it. Trouble is, how do I lubricate this thing?

I've got it on my work bench right now. On the back of the electric motor there is a cap with a small hole jutting up. I am tempted to pry it off with a screw driver to have a look at what it inside, but it reminds me of something I would have done when I was 16. :huh: I am much more cautious now.

On the other side of the assembly there is a mechanism holding the motor to the fan housing. I have applied some WD 40 there, but I need to apply some lubricant to the other side. Any input? Should I be using something other than WD 40? Thank you for your feedback.

With all the trouble your going through, and since you allready have the motor out, just replace it.

Agreed..even if ya do get it to stop squealing, I'll bet it either seizes or dies within 6 months. Replace it and make sure it has sealed bearings, which is probably why you are having such a hard time oiling your noisy one.
