I hate to throw away repairable items. After replacing my last 2 attic exhaust fan motors, at a cost of $60 each, up from $25 the last time I replaced them, I asked a local motor repair shop about rebuilding them. They said just replace them. I took one apart and noticed their are no bearing to replace, just a packing resembling cotton or felt, soaked in an oil that evidently lets oil seep out slowly when heat is generated to lubricate the shaft. Other than that there seems no reason this motor would not work as I lightly lubricated the shaft and it worked like new. My question to throw out there is what is this packing. It must be something that exposed to high heat will not ignite.
