Paul Carmody Posted February 1, 2023 Share Posted February 1, 2023 (edited) The foreground shaft is in a near pristine fan that someone along the way,or maybe a factory worker put a wick that was too long and bottomed out with no spring action.Notice the deep groove from wick right compared to the wick on the left that was proper length on a greasy well used fan with an unworn shaft.The old crusty fan had caked oil everywhere and was probably oiled regular.The bearing is also shot on the grooved shaft fan .But the transplant is near ready.

Paul Carmody Posted March 17, 2023 Author Share Posted March 17, 2023 (edited) I ran into a new one on this Westinghouse.Something to check before assembly.It would run fine then make terrible noise.Sometimes it sounded like it was binding at startup.I would shake it around and mess with the blade and it would go away ,almost.There is virtually no slack in the bearing so I determined that was not the problem. I had used the spacers from the original to the transplant rotor because they were in better shape.The brass spacer on the left is rear and it covers the rear bearing exact .To distribute load I would assume.The one on the right is front and must be the proper OD as the rotor snout fits with precision into the front bearing case.These brass spacers were consistent in both fans.As it turned out the inside diameter of the spacers to the shaft fit too snug,and the front one was causing the rotor to bind in the front case ,and on the shaft itself judging by the marks.I lightly sanded the ID of the spacers so they fit slightly looser on the shaft.After the painstaking realignment of the front bearing case once again ,this is one good running motor.All that can be heard is the blade and wind. Don’t worry,this is the junk that was replaced! Edited March 17, 2023 by Paul Carmody Quote Link to comment Share on other sites More sharing options...
Keith Wheaton Posted March 21, 2023 Share Posted March 21, 2023 Interesting finds! As a novice, this begs the question - how does one properly create a wick of the correct length? Quote Link to comment Share on other sites More sharing options...

When you reinsert your new wick with spring just prior to threading the cup in, you can feel the pressure exerted against the wick/shaft. If it feels excessive, it probably is. Untread it and check the shaft compression against the wick. BTW......deep grooves in the shaft didn't happen in one weeks 24/7 operation. If you are running the fan here or there, please sleep well at night. Lol. Edited March 21, 2023 by Russ Huber Quote Link to comment Share on other sites More sharing options...

I have an Emerson 29646 I'll hopefully be reassembling soon. 5 minutes ago, Russ Huber said: BTW......deep grooves in the shaft didn't happen in one weeks 24/7 operation.

I've got an nearly-100 y/o fan that survived this long; I'd love to do whatever I can to give it the opportunity to last another 100.

Paul Carmody Posted March 21, 2023 Author Share Posted March 21, 2023 The wick was crammed so tight you can tell the bearing area in first pick is also worn.I first tried the fan it ran fairly quiet with a slight rattle and it made it feel like there was no slack in bearing.Once the tension was off it sounded like a model A running with a rod knock.This was after the restoration was near completion that I discovered the shaft and bearing wear.Just the wear on the wick surface didn’t cause a lot concern.
