Furnace blower bearing isolaters....

[Rfsmith48]

Hey guys,

I got another interesting problem. (At least to me.)

45 year old Lennox furnace, model G10-165-1.

Furnace and blower run fine, but the blower makes a lot of noise when running.

I got it apart this AM. There are 2 sets of rubber isolaters: Small rubber pads at the pivot point for the motor frame: They appear to be OK. Larger rubber donuts that isolate the main bearings from the motor frame. They appear to be very dried out, with some cracking.

Does anyone have a go-to supplier for Lennox products this old? I spoke with several Web vendors this AM, they didn't laugh at me, but had no help...

All advice is appreciated.

All advice is appreciated.

That blower should have caps that you can remove and add bearing lube. Did you do that ?

If you let them run dry they may need to be replaced.

Good Luck.

Thanks DonL,

The bearings themselves seem to be fine. The rubber isolation donut is shot on the drive side, not much better on the opposite side.

I have found one website with (Apparently) the replacement parts. It looks like I will have to buy the bearings to get the isolation donuts.

Thanks again,
