Removing Westinghouse tank motor bearings question.


Recommended Posts

Posted (edited)

Hi fellow fan collectors.  I have a feeling my Westy tank may need motor surgery within the next year or so.  The bottom of the inside of the forward bearing is worn by about 1/40th of an inch or so, causing the fan to slow down a lot, and it has slowed down to where the centrifugal switch has re engaged, and my idea of fixing it is pressing the forward bearing out and then putting it back in the housing upside down.

Now, I know I'm probably going to need a press to get the forward bearing out, but before I do the operation, has anyone else removed forward bearings from Westinghouse Tankmotor fans?  I also know the stator assembly will have to be removed from the housing, but are there things that hold those forward bearings in like screws, bolts, or what not?

If you’re going to remove the bearing, why would you go to all that effort just to install the old bearing upside down. 
send the whole thing to Darryl Hudson and he’ll make a brand new set of bearings.

Not only is turning the old bearing upside down a bad idea, but it's also a mistake to replace just one bearing. I promise you, that for the shaft to sag 1/40", (i.e. .025") in the worn bearing, there is also wear in the opposite bearing.

If the bearing can’t be removed without risking breaking the housing, one of our machinists (not me) might be able to machine the existing bearing with a larger hole and press a brass sleeve into it, essentially “renewing” the old bearing.

I'd go with Darryl Hudson. He'll do the job correctly which is what you want if you are going to keep the fan.

If that's the case, a machinist can also entirely cut away the old bushing and install a new one.

After seeing the post I did a search "tank bearings" with the all words options. At least 20 posts came up and most were able to replace or have replaced the bearings.
