Jim Roadt Posted September 11 Share Posted September 11 What do I have wrong here? Two star Oscillates only slightly It has been awhile since I've been in one. Does the top star come off to remove lid and check gears? Do I have the oscillating arm on correctly? Seems to be some space down there and cant tighten anymore. #neverdeletepictures Quote Link to comment Share on other sites More sharing options...
Anthony Lindsey Posted September 12 Share Posted September 12 The bottom star is in the middle which sets it to not oscillate. Loosen the bottom star and slide it out to the edge then tighten star. 1 Quote Link to comment Share on other sites More sharing options...
Anthony Lindsey Posted September 12 Share Posted September 12 Also, the bottom plate should be flush with the bottom of the wheel. Yours has a little bit of space. Quote Link to comment Share on other sites More sharing options...
Jim Roadt Posted September 16 Author Share Posted September 16 oscillating mechanism on properly now and it will oscillate, however, when it gets to an end of a turn the blade gets more difficult to spin and will stop. if I turn off the oscillating mechanism it will run fine if it is pointed straight ahead. As I manually turn blade in oscillating mode I can feel the blade starts to bind up as i get closer to the end of a cycle ( pointing left or right ). When it is in the center of a rotation it spins just fine???? Quote Link to comment Share on other sites More sharing options...
Steve Stephens Posted September 16 Share Posted September 16 Jim, I had a brass bell oscillator that would just begin to bind I think near the end of the oscillation,. What I did to fix it (it's been a while) was to note that the osc. linkage looked to be installed wrong, maybe upside down or installed 180 deg. off. Anyway, I think I repositioned the linkage and it works great now. Quote Link to comment Share on other sites More sharing options...
Anthony Lindsey Posted September 16 Share Posted September 16 I'm not sure. A sticky Oscillator shouldn't slow the motor. Stop oscillating yes but slow the blade and motor down? If you turn the brass bell with your fingers when it gets to the edge does it get past that point and speed up again? Quote Link to comment Share on other sites More sharing options...
Steve Stephens Posted September 16 Share Posted September 16 Jim, YES as I recall. The oscillation had a small but definite hesitation then resumed the normal oscillation. But I did have to either flip the linkage or swap it end for end; don't recall which. Try operating the fan by rotating the oscillator disc and watch to see what could be hanging things up. I think mine did run "before" but hesitated and I thought that wasn't good for the motor or linkage. Quote Link to comment Share on other sites More sharing options...
Jim Roadt Posted September 17 Author Share Posted September 17 this time did not come to a complete stop but chugging and noisey 20230917_111802.mp4 Quote Link to comment Share on other sites More sharing options...
Russ Huber Posted September 17 Share Posted September 17 Did you try disengaging the oscillator and does the noise goes away? Quote Link to comment Share on other sites More sharing options...
Jim Roadt Posted September 17 Author Share Posted September 17 makes the same noise when disengaged. Quote Link to comment Share on other sites More sharing options...

I think we took the oscillator arm off, saw that it was slightly bent, and gently pressed in flat in a vice. It worked well after that.

You can pop the can on your motor housing, remove your rotor and check your rotor and stator surface for scuffing contact. How are the bearings? Does the blade side rotor shaft lift up and down with significant play? Quote Link to comment Share on other sites More sharing options...
Russ Huber Posted September 18 Share Posted September 18 When your fan is running the clunking noise keeps near perfect timing. Whatever the bad thing is that is raining on your parade, is happening in the same spot. Quote Link to comment Share on other sites More sharing options...
Russ Huber Posted September 18 Share Posted September 18 You could try threating the fan with a root canal without Novocain. It may just clear up on its own. 🙂 Quote Link to comment Share on other sites More sharing options...
Bill Dunlap Posted September 18 Share Posted September 18 I would have killed for that sound on my bicycle back in the day.... Try hold the fan upside down while running. (be careful) or lean it backward and forward. That may give clues as where it's coming from. 1 Quote Link to comment Share on other sites More sharing options...
Jim Roadt Posted September 18 Author Share Posted September 18 (edited) no significant play no wear spots on rotor same noise upside down getting better 20230918_083336.mp4 Edited September 18 by Jim Roadt spelling Quote Link to comment Share on other sites More sharing options...
