50" Casablanca Delta II ceiling fan: new bearings and now four speeds

0:00 5 blades 7:34 4 blades 12:45 2 blades 16:26 The motor running without the blades The original pull chain (3-L, 3-L-1, 3-2) was replaced with a pull chain for fans with dual capacitors, which would be L-1-2-3, L-2-3, L-1-3, L-1-2. I found a pull chain switch (Zing Ear ZE-208D) that can make it have original low, medium, and high sequence, which is a double layer pull chain which was advertised as L-1, L-2, L-3, and off at one layer, and L-1-2, 1-2-3, 2-3-L, 3-L-1 at another layer. It turned out it was L-1-2, 1-2-3, 2-3-L, 3-L-1 at both layers, but I managed to modify one layer to go L-1, 1-2, 2-3, 3-L, and I connected a hot wire to "L" both layers and at a layer that goes L-1-2, 1-2-3, 2-3-L, 3-L-1, I connected a 5uf capacitor wire to "3" and 7.5uf capacitor to "1", so it would be 5uf, 5+7.5=12.5uf, and 7.5uf at that layer. On the layer that I modified, I connected a high speed wire to "1", and since high speed wire bypasses speed capacitor, it's now low, medium, and high sequence. Except that if you pull the chain halfway from medium to high, it just connects to a 7.5uf capacitor, making it like a functional low. It's like the case on most if not all SMC ceiling fans with triple capacitor; if you pull the chain halfway from high to medium on those, it can result in a different low, sometimes faster low, sometimes slower low, depending on if a capacitor used for medium and low is higher or lower than a capacitor only used for low. So the 4 speed is unintentional for that Delta II, it's just the only pull chain switch I could find that can make almost all triple capacitor fans, including this fan, have low, medium, and high sequence. It turns out the chain modification isn't really necessary, On one layer you can just connect hot wire to "L", 5uf capacitor wire to "3", 7.5uf capacitor wire to "1", and connect a wire from "2" on one layer to "2" on another layer and connect a high speed wire to "1" on that other layer. If you had seen my previous video and read the description, I also took that 5uf capacitor I added out of that fan and can use it on another fan that needs one. In addition to wiring a correct pull chain switch and unintentionally converting this fan to four speeds, I also replaced the bearings, so it has no bearing issues now. It didn't make noticeable noise with the blades, but bearing noise was noticeable without blades so I just replaced the bearings because I'm sure if it made noticeable noise without the blades, it's going to start having real bearing issues sooner or later. It is dated September 24, 1996, and is 11th unit made that day. This one was missing screws to the flywheel and a Hang-Tru mounting bracket, so I bought screws and borrowed a mounting bracket from another Casablanca. RPM estimation with 5 blades: 38/63/103/204 RPM estimation with 4 blades: 39/64/106/208 RPM estimation with 2 blades: 46/88/146/274 It blows tons of air with an Emerson K55 motor and is silent and wobbles a lot because the blades are out of clock. This fan is shown on all four speeds with five blades, four blades, two blades and I also showed the motor running without the blades to show the difference between the old bearings and new bearings.
