How to remove fresh air blower plastic fan from motor shaft??

Trying to Mcgyver my fresh air blower before just ponying up and buying a new motor. Makes an awful squeaking racket when it decides to work. I pulled out the whole assembly and determined it's the lower bearing making all the noise. I'd like to lube it up and see how much better it gets. Looks pretty grungy at the moment.

So how do I pull the plastic fan off the motor shaft without breaking it? Doesn't look obvious to me and don't see any set screws. Is it just pressed in place?

Any recommendations on lube? Axle grease, teflon bike chain lube, WD-40, olive oil??? (okay that's a stretch but it's all I have in the house at the moment).

I'd recommended getting something like an electric motor oil, 3-in-1 makes one and so does liquid wrench.
No on the grease and WD-40.
Sry can't answer the fan pulling question.

Mine was noisy so I sprayed it clean with contact cleaner and lubed it with a light lithium type spray oil, without pulling blower off of shaft. Works great.

Insert a hefty flat blade screw driver under the squirrel cage. Twist the screw driver and it will start to force the squirrel cage off the shaft. Once it starts moving it is fairly easy to remove.

sit down and support the fan with your legs/knees. the shaft usually protrudes a bit beyond the plastic. get it started by knocking it flush with a small hammer. then use a punch to finish the job.

Thanks... I'll give those a shot tonight when I get home. I'm thinking a little bit of cleaning and lube will save me the $100 for a new motor.... at least for a little while.

Lube-wise Phil's Tenacious Oil is a nice split between the lighter oils (TriFlow, 3 in 1) and the heavier grease you will never want to use.

Be sure the fuse for your blower motor is in good nick and the correct one. Stories of these fans overheating and whatnot seem legion.
