comfortmaker rpj2 blower wheel problems


I have a Comfortmaker that started making a loud grinding noise a couple of days ago. I shut off the unit when I heard the noise and it slowly stopped grinding. Then I kicked it back up and it started doing it again. I took the blower assembly off the back of the furnace and spun the motor. The blower wheel doesn't spin with the motor. I spun the blower wheel and it didn't turn the motor either. There's a lot of play with the blower wheel, so I'm assuming it's either loose or not attached at all.

I'm a novice at home repair (just figured out how to repair my washer and dryer a few weeks ago)... I'm just wondering what I should do with the blower assembly. Should I replace the blower wheel or should I see if I can tighten the assembly to the motor shaft?

If I need to tighten it, how do I do that?

Sounds like the blower wheel fins have broke loose of the hub. Take the wheel into a HVAC supply house and buy the same size.

edit: Before you buy a new one check the square headed bolt that holds it onto the shaft. It should be on the flat part of the shaft and tight with the wheel not rubbing the housing. Never saw one of those come loose yet but there's always a first time for everything.

There's some kind of housing around the blower wheel which I detached from the back of the furnace wall and what I'm assuming is an exhaust vent(?). I can't seem to detached the metal housing the blower wheel is in from the motor itself.

How do I go about doing this?

Assuming you removed the bolt that holds the wheel to the shaft and have the motor mount bolts out, clean and oil the shaft. Hold the hub and rotate the shaft with the weight of the motor pulling it through. If that doesn't work you probably want to call a service man out. My wheel puller cost more then a service call .
