@ beenthere: The belt is snug but not overly tight. It isn't new but shows no signs of cracking.
@Red Squirrel: I don't think it is a multi-speed motor. It only gives 1 rpm rating of 1725.
Here are some pics of the blower/motor and some electrical component I originally thought was the run capacitor but now I'm not so sure. Does anyone know what it is and if it could be the reason the motor doesn't seem to want to get the blower up to speed?
Oops. Sorry. The blower for the furnace. I've checked all of what I think to be obvious culprits to making the vents not blow very hard (furnace filter, dampers, vent openings, loose/bad drive belt) and everything seems okay but the blower doesn't seem to be moving very fast. The only thing I could think of is that the motor could have gone bad and won't get up to speed. I also thought it might be a bad run capacitor but I don't see one. There is some component that I can't identify I thought might be the capacitor but I'm not sure. Here are some pics. Thanks for the feedback.
@bobelectric: Agreed, furnace needs replaced and any contributions toward the $5k to replace it will be greatly appreciated
