Marc Sova Posted March 28 Share Posted March 28 (edited) Scored my first century S3 yesterday. What can you tel me about it? What year? Pot metal or no pot metal? Is it Japan or black paint? The little switch on top of the gearbox does not move and I don’t want to force it. Any tips on that? What’s the best method for getting oil in that little ball bearing type oiler? (My zoom spout oiler didn’t really do a good job of pressing the ball in and putting oil in… I have a couple old metal pump oilers, but I just haven’t got them cleaned up and loaded with proper oil yet). Also, the switch is missing the plastic/bakelite(?) cover piece. Do the usual suspects that make these have them for this model? It works great on all five speeds. Pretty distinct too. Obviously a total tear down of the gearbox at least is in order, but I’m not ready to monkey around with this yet since I’ve never had one of these. Cage has seen better days. But it is all brass and fixable. I’m sure. Maybe with a couple new S wires, etc.. Also…,whereas Emerson’s have that adjustible Collar, those seems to have a sort of cogged mechanism that you can rotate the top half of the fan with am I correct in that? thanks Edited March 28 by Marc Sova Add content 3 Quote Link to comment Share on other sites More sharing options...
David Kilnapp Posted March 28 Share Posted March 28 (edited) Hi Marc. Every good collection should have a skeletal S3. The switch is perfect as it is. There is no bakelite covering on it. You'll see why when you open the bottom as there is a hard leather part of the speed coil switch that insulates. You can see it below just peering out from beneath the switch. The only pot metal on this fan is the gear box as far as I remember. The fan is definitely japanned. This is a five speed fan but the issue with some of these speed coils is that sometimes, there isn't a lot of difference between the speeds. Be gentle around the speed numbers as you clean. Those are nice to have and hard rubbing will remove them. As I recall, one of our members produces a decal that will replace these numbers with Slow, 2, 3, 4 and Fast. This fan's gears are a marvel of engineering and very clever. Remove the rear plate on the gear box and you will see this gear: The two little ball bearings compress into the shaft so that the little lever (the one you say doesn't move) has a nub on the end of it that fits into the far right groove pushing the center gear on and off of these ball bearings which locks and unlocks the oscillation. The rotor looks like this: The little lever appears on the far right of the picture below. You can see the nub on the end of it. As i recall, there is a set screw on the back of the gear case that must be removed to pull this lever up and out. That set screw fits into the center groove on that lever. The press oiler on top of the gear case can be removed with a small open end box wrench for cleaning so that it will depress more easily (above picture far left). The worm gear (below) can easily be removed so that you can slide the gears out of the rear case to clean them repack in red and tacky grease. That center cog mechanism, allows the re-orientation of the fan's arc swing. You would move that while the fan is off. It controls where the arc begins and ends. Very clever design. The stator comes out easily on these fans. Take care to label the wires so you know what wire goes where on the speed coil. I attach diagrams which you may find useful. Hope this information is helpful to you, Marc. Congratulations on a nice acquisition! Edited March 28 by David Kilnapp 3 Quote Link to comment Share on other sites More sharing options...
David Kilnapp Posted March 28 Share Posted March 28 I should also point out, that there are two covers on either side of the gear box. They are made of brass (painted black) and can be pried off with a putty knife. Take care when you do this as they are very pliable and will bend. You can see one in the picture below. 1 Quote Link to comment Share on other sites More sharing options...
Marc Sova Posted March 28 Author Share Posted March 28 Wow. Thank you SO much for this through reply. So as far as getting the osc on/off lever working…. I guess I pretty much have to go into the gearbox and gently pull things out and see what I got. Do you think the little nub or something might be broken off as to why it doesn’t move?

David Kilnapp Posted March 28 Share Posted March 28 Hi Marc. No, I don't think the little nub is broken off. That would be very unusual. Unscrew the set screw and lift the lever up and out and you can examine it. A good clean of all those gears will loosen everything up nicely - not to worry. 1 Quote Link to comment Share on other sites More sharing options...
Marc Sova Posted April 2 Author Share Posted April 2 What year is mine btw??? Quote Link to comment Share on other sites More sharing options...
Lane Shirey Posted April 3 Share Posted April 3 All cast iron. They are very good fans but many have shot bearings from being run to death. 1 Quote Link to comment Share on other sites More sharing options...
