Many HVAC parts are available from Amazon. I know they sell FASCO inducers as well as showing cross-references for proper application. Reading the customer reviews might also give the OP a better idea if replacement is something he is comfortable with.
Definitely looks like that. Nice find! However, I am going to stick with what I have for the time being. The furnace unit overall is old so if it goes I will likely replace the entire unit. I wish I had the manual for it. Would like to know if its possible to oil such a motor. :S
Many furnace repair guys save motors and stuff they think might be useful when changing out a furnace. My motor died on a Sunday a few years ago in a blizzard and I called around and no one would sell a motor just come out and replace mine in a few days. I called one guy and he said he had a garage full of parts and if I could get in his place he would sell me one. I got there and he had a 500 ft drive with 3 feet of snow in it. So I dropped my blade and cut a slot back to his shop. He had two motors like I needed and I asked how much for both and he said they are yours if I made a couple more passes at his driveway. Worked out good for me and him and I have a spare now.
