I have an Amana 90 furnace and would like to replace the bearings on the exhaust gas blower motor, they are churping worse than a bird on a spring morning.

The challenge is I am not sure how to get the fan off the motor shaft, is this possible? It appears to be glued on but it is difficult to see so I am looking for anyone who has had experience with this.

Appreciate any advice or direction you can provide.
 
There should be a set-screw in the hub of the squirrel cage that secures the squirrel cage to the motor shaft. It may be epoxied onto the shaft or perhaps just a sealant around the shaft & hub. Another possibility is that this is a one-piece unit. In addition, the bearings may be sealed and not replaceable and/or servicable. Try to nurse some light-weight oil into the bearings and see if that alleviates the problem.
