How to lubricate fan bearings in furnace?
So in our 27-year-old Winnebago Warrior, we have a Suburban NT30KLT furnace. In the last couple of years, the first time it fires up you can hear the fan bearing squalling a bit and then it quiets ...

Couple of post prior I gave you a clicky to the zoom spout oiler. What you can't tell is that the thing pulls out about 12 inches and can get into just about any tight space.
The problem is that I cannot see the fan. When I pulled the metal covers off of the intake and exhaust I could barely make out the cage of the fan, but can't get any access to the fan motor bearings.
BTW, don't get snippy with posters. If you knew everything you wouldn't be asking these dumb questions.
I just get annoyed when I ask "how do you access the motor in the furnace" and a third of the responses want to debate the proper word for a bearing and another guy wants to go off on some tangent about Harbor Freight.
We have a Suburban furnace and it's one of the ones with only the little plate with the Intake and Exhaust tubes on the outside. I'd much rather have the version with the large full cover that lets you do more "work on the furnace" labor from outside.
That's what I've got.
So the answer to all of this is: "You've got to pull the furnace assembly to get access to the blower motor".
