Heater Blower Motor ~ Are these repairable?, ....loud squeals when running Options

[Woodside914]

Other than removing the center nut holding the fan blades, is there any way to get inside this blower motor to repair or lubricate this motor from my 1971, or are these motors factory sealed?

It whines & squeals inside when it's run at medium-high speeds. I'd hate to replace the blower motor with another good used one (presuming I can find one), but I may be forced to if I cannot fix this.

Has anyone had success on these?

Thanks,
Ken

So, I took the heater blower apart last night. Quite easy getting in there, but what an ugly mess inside! After some consideration (and a beer), I decided not to fuch with it any more, because I really don't know if I'd fix it correctly....and, I might really fuch it up!

So, at the good advice of some members here, this afternoon I took the motor to a local electric motor repair shop, in my case called Palo Alto Electric Motor Corporation. I think that was the right move, as they'll do a complete degrease cleaning, and shaft lubrication, and repaint the silver base & black housing for just one hour $140 labor charge. And, if I want to, they'll replace both sides worn brushes for about another $60. Ya know, I'm good on that. Whole lot quicker & easier for me...lol. If any of you guys are interested in getting your old & squeaky heater blower repaired , they're at (650) 493.5585

Regardless, thanks to all who chimed in here....


For grins, here is the base with the fan removed. Just pull the two retaining rings, and remove a couple bolts & screws, and it's apart....and, dirty as hell since 1971.
