The bathroom exhaust fan was sounding like I was parked near a railroad track with constant trains Thumbs Down rumbling Thumbs Down down the rails. The fan was replaced shortly after the visit to Elkhart. Decent fan, so I thought. Short lived, maybe? I do use the fan all the time when the Barth is occupied. Traveling down the highway or parked. The fan is ON. The bearings may have picked up moisture. Whatever they were NOISY! head bang Fan motors are about $50. I am always up for a better deal.
I pulled out the armature in the motor and slipped on new bearings. The bearings cost anywhere from $2.00 to 22.00. I opted for the $2.00 since they all came from China anyway.
Put the new bearings and she is quiet. If I get five years again I will be delighted with my $4.00 investment. It takes about an hour to replace the bearings.
Extra bearings will go to swap meet. If you need fan bearings, at $2.00 plus shipping, I will send you up to the six I have left.

Kevin, I have found if the bearings are just the bronze bushing type, spray them with some penetrating oil let it set a bit then use a good oil to finish. I have used this procedure for all types of these motors, seems to work for as long as the initial motor did. If there is a cloth oil absorber even better. Most of the time no need to disassemble the motor.

Sure, blame it on the fan... (I think the bearings were damaged by noxious fumes) ROTFLMAO

Better is to immerse the bearings in 10 weight oil (like 10W30) and heat to 275°F, then allow to cool naturally. Using this technique, the oil migrates to its natural repose.

Sintered bearings retain oil in the pores; when the shaft heats up the bearing, the oil expands and lubes. When the shaft stops, the bearing cools, and the oil retreats back into the pores.

If the bearings are solid metal, use grease.

Now that is some FUNNY SHITCrap. Please also note during the time when the fan was not working my propane detector never detected any fumes.
Back on topic I have roller bearings in the Barth fan. Thank You Rusty. I have "Sintered bearings" in the house furnace blower. I just replaced them prior to the heating season. How often should I boil the bearings in oil to increase life expectancy? I used to boil my motorcycle chain in oil. Do you think boiling the sealed roller bearings in oil would increase life expectancy for the roller bearings?

Did I say that I got 8 roller bearings for $4. Sorry to confuse you Duane. My $4.00 investment is only for the two bearings I replaced. I still have 6 bearings up for members here. They are 3/8" X 7/8" X 9/32" sealed bearings. My photo of the bearing went to the wrong satellite or something. I have not got a round tuit on this posting yet, for the swap meet forum.

Who needs expensive bearings? Go to the swap meet page.

The brushes on those fans like to get pretty dirty too.

I pulled the brushes off and cleaned up that end of the business.

fan worked great after that.
