want to replace exhaust fan motor - how to remove blower wheel?


We need to replace the motor in our bathroom exhaust fan.

I've located a replacement motor online. Now I need to remove the squirrel cage blower wheel from the old motor so I can put it on the new one.

How do I get it off? There isn't any sort of nut holding the wheel to the shaft that I recognize. It looks like a half circle. Is there a special wrench to use? I tried gently pulling it off but no go.

Bathroom fans are usually disposable, unless it is an old made in USA quality fan. Is your blower wheel plastic? If there is no set screw to the flat spot on the shaft, it is Probably pressed on, so you have to press it off, if you can, without breaking it.

Pictures Please.

Might want to check one of the box stores. I know they stock some. The ones I've bought already had the fan on them.
