Ron May Posted December 20, 2022 Share Posted December 20, 2022 Several years ago I restored a clamshell, serial number 23409. That fan had grease cups. I bought another one and just noticed the cups are missing. The only difference in the 2 fans is the grease cups and the one that's not restored has a 150 prefix in the serial number. I've searched the web and I've seen them both ways. Does anyone know if they stopped using the grease cups at some point, or do I need to make a new set when I restore this one. 1 Quote Link to comment Share on other sites More sharing options...
Russ Huber Posted December 20, 2022 Share Posted December 20, 2022 The 1916 introduction models started with the grease injection screw downs. Grease cups appeared 17-18. With all due respects, being it is not a rare Belding fan motor from 1890, which grease lubrication option would you rather have to make? 🙂 As long as you don't involve Steve Stephens into the purist debate, take your pick and live with it. 🙂 Quote Link to comment Share on other sites More sharing options...
Dave McManaman Posted December 20, 2022 Share Posted December 20, 2022 Beautiful restoration Ron. And interesting reading about the injection screws on the first year Russ. I hadn’t seen those before and just looked on the old site to see more. I picked up a grease cup clamshell this past summer and haven’t done anything with it yet. Serial # is 23767x. Just noticed I’m missing both of the little “twizzle sticks” for the cups. 1 Quote Link to comment Share on other sites More sharing options...
Russ Huber Posted December 20, 2022 Share Posted December 20, 2022 (edited) Ron, to be a little more helpful, I was searching the web for at least one clamshell example with the oval brass base tag with grease injection screw downs. I couldn't find one, not to say I didn't miss one, I just couldn't peg one down. As I stated, the screw down grease injection models with the rectangular base tag were first generation. However, there are rectangular base tag models with grease cups which would be late 16".....early 17? The 1917 -1919 models had the grease cups. The clamshell tags started rectangular brass, than oval brass, and then aluminum. Menominee may have mixed the brass & aluminum oval base tags later (18-19?). Good luck finding a clamshell rectangular base tag in aluminum. Edited December 20, 2022 by Russ Huber 1 Quote Link to comment Share on other sites More sharing options...
Ron May Posted December 20, 2022 Author Share Posted December 20, 2022 Thanks Russ, helpful information as always! This fan isn't high on my list of priorities, once I get around to restoring it I think I'll turn some brass grease cups. You know I've never been much of a purist unless I have to be.

Russ Huber Posted December 20, 2022 Share Posted December 20, 2022 This may help you follow in the footsteps of Steveo in his quest for patina and purity. Menominee is announcing changes in 1917 electrical trade to the 1916 introduction 8" AC/DC stationary (clamshell). I think we can pretty much take to the bank one of those changes is the grease cup. 1 Quote Link to comment Share on other sites More sharing options...
Bobby Gaines Posted December 20, 2022 Share Posted December 20, 2022 This is one I restored a few years ago, It has grease injection ports. 1 Quote Link to comment Share on other sites More sharing options...
