Morning everyone,

Beautiful day in Geneseo IL, other than a little cold.  I've got a Westy 6 blade 12" BB/BC can motor fan, and haven't worked on one like this for years, but I'd like to take this one apart for a decent resto.  The problem is, the stud that goes from the motor through the knuckle to secure the motor to the base doesn't want to come out of the knuckle.




Using the search term "164864B" brings up 30-something threads, and about 1/2 or 2/3 of them involve this same topic to one extent or another.  Unfortunately, most of the threads have pictures of the enclosed oscillator housing and knuckle all busted to hel! and I still don't understand what retains the steel motor post in the knuckle.  After removing the two screws and the wing nut, the fan motor flops around freely forward and backward, but the post doesn't want to come out of the knuckle.






I thought this thing would work just like the R&M knuckles, but that sure isn't true.  So HELP, what am I missing here?  The bolt with the wing nut obviously has a hole in the center for the stud to pass through, but after removing two set screws, the knuckle is still hanging onto the motor stud.  I really don't want to break this thing because if I can once get this can motor SOB restored I promise to never again lay hands on another one.  So if someone can help me with this problem, I'd greatly appreciate it!  Thanks.


Jim

Jim, I restored the same fan. My oscillator housing was broke when I got the fan. I would first spray some WD 40 around the pivot. I think there's a hole in the bottom of the pivot. Use a punch and tap lightly with a hammer. It should come right out.

Thanks Vic, that's what I thought the assembly would look like, and it would seem that I'd be able to punch the steel pin out from the bottom of the pot metal knuckle, which does have a hole where you can see the end of the pin.  I've hit the whole thing with WD and tried to tap the pin upwards and drive the motor and oscillator housing away from the knuckle.  Absolutely no luck, but I don't see anything like a "C" clip or set screw hidden anywhere that would prevent the pin from coming out of the knuckle.  It's starting to drive me crazy, but I refuse to break out the BFH because I'd for sure destroy something.  Corrosion between the pin and the knuckle, maybe, but there's about 1/16" free play up and down where the pin moves in the knuckle, then it goes solid like there's a clip or set screw.

You got any other ideas, Vic?

There isn't anything else that would keep the shaft from coming out unless the knuckle is a little swollen  because of it being pot metal or that shaft could be a little bent.

Pull BOTH bolts all the way out. One of them rides in a groove on the vertical shaft.

Rod, there's only the one bolt that the large pin that's attached to the bottom of the motor goes through.  That bolt has the wing nut on one end, plus there are two set screws, one that limits the tilt and is in the neck just beneath the wing bolt, and another that goes in through the head of the bolt and, I'm not sure, but maybe it keeps the motor from being pulled out of the knuckle (which is exactly what I want to do), but both setscrews are removed.  This SOB isn't complicated, but I'm too stupid to see what I'm missing.

In a word, SUCCESS!  Removing the stud holding the motor to the knuckle and base was a matter of applying the appropriate level of brute force and massive ignorance.  The whole assembly is just as simple as it appeared initially, and the only thing holding the stud into the knuckle was 100 years or so of just being there.  No actual corrosion that was visible, maybe just a little bit of old lubricant that had solidified and wouldn't give it up to the WD 40 and gentle persuasion.




I screwed the base down to a substantial workbench, flopped the motor over so I could access the bottom of the knuckle where there's a hole exposing the bottom of the stud, and then applying a small hammer to the larger punch pressed against the bottom of the stud.  It took a lot of moderate hammering to get the stud to start moving up, and then switching to the smaller punch when the bigger one got tight in the access hole in the knuckle.

Didn't require a BFH at all, just accepting that if the stud didn't come out, there would be some broken pot metal.  The stud gave up and all was well!

If you haven’t resolved your problem, may I suggest you go to YouTube..Type in Westinghouse 164864B. There some helpful videos. I have this exact fan. 
Mine runs very smooth after 5 months. And it is gorgeous!!
Best Regards, Malcolm

Thanks Malcolm, that's a good idea on YouTube, I'll do that.  There's always something interesting that comes up on YouTube whenever you search on anything.  For me, its those flicks of huge old engines starting up and running.  I never actually thought of searching on the 164864B.  Jim
