How easy to pull furnace fan out?
Today my furnace fan started screaming like a banshee on startup. It howls for a few seconds then quiets down. I know I need to pull it apart and lube the bearings, if equipped, or otherwise effect...

Well, I finally got around to doing something about my furnace fan today.
It got so bad I had to shut the thing off.
Thanks Chris, for your excellent detailed instructions. I followed them and soon held the fan motor in my hand.
I am surprised it ran at all. The motor shaft was nearly completely seized. It was very difficult to turn with the squirrel cage on. With it off, near impossible to turn with my fingers.
I squirted some fine oil on the shaft, directed inwards towards the bearings, on both ends, and got the shaft rotating. It freed up very easily so I spent a little time working some oil into the bushings/bearings, whatever they are. Soon it was spinning freely.
There was a little end float in the shaft, but it was tight side to side.
I put it all back together and fired it up and yahoo! It is whisper quiet once again.
Thank all for your input.
