imajedi Posted August 3, 2013 Report Share Posted August 3, 2013 My rotor keeps coming off my TC sub (see pic). The first time it happened I took it apart and squeezed the rotor back together with the gear and portion that appears to press fit with the rotor. That didn't work because it came off again. My question is how is the rotor supposed to attach to the gear below. I can't see any thing other than a press fit to the silver ring. This seems like a really stupid idea though. Why would they make that all one piece? Maybe mine is broken? Any advice about how these two pieces are supposed to go together and how I can permanently fix mine would be greatly appreciated.

Jkay Posted August 3, 2013 Report Share Posted August 3, 2013 the winding gear is press-fit to the rotor weight. If you are certain that the first time you fixed this that you seated the weight completely, then your rotor's hole is probably too big and you have a problem. Perhaps a touch of red loc-tite, and wait until it sets hard before re-mounting the rotor and gear assembly. Quote Link to comment Share on other sites More sharing options...
SSTEEL Posted August 3, 2013 Report Share Posted August 3, 2013 Don't use any glue near the movement, remove the gear, and bond it firmly into the weight away from the watch, and leave to set good for several hours. Quote Link to comment Share on other sites More sharing options...
Ephry73 Posted August 3, 2013 Report Share Posted August 3, 2013 Best bet is to source another rotor. Simple fix and in the interim you can manually wind it. E Quote Link to comment Share on other sites More sharing options...
imajedi Posted August 3, 2013 Author Report Share Posted August 3, 2013 Thanks guys. I pressed it back in again and put it back together. If it comes off again it getting glued. One problem with pressing it in is that if it's not seated perfectly, it rubs in certain places when it spins around. Makes a sound and is annoying. A couple other comments: I tried switching the assembly out from a noob sub I have but the gears didn't mesh. I'm guessing because my TC has an ETA and the noob has Asian clone. It's really annoying that they cloned movements and didn't go 1 to 1.Also I noticed that on my TC the screw that holds the rotor gear assembly on never actually becomes tight. If I keep tightening it, it will just keep spinning like it is stripped although it does hold the rotor in place. On my noob sub, the screw tightens.

woof* Posted August 3, 2013 Report Share Posted August 3, 2013 Yeah, I'd think I would just get a new correct rotor assembly at this point. The hole sounds out if round, and now something's stripped. You could also rob one from a dead ETA. Quote Link to comment Share on other sites More sharing options...

I've never had a problem assembling a clone rotor to an ETA movement or vice versa. Based on the other information you supplied I'm guessing there's something else wrong with yours.

I tried to move it around to get it to mesh but it wouldn't seem to. Probably pilot error in this case. Thanks for sharing your knowledge.

imajedi Posted August 16, 2013 Author Report Share Posted August 16, 2013 Well it broke once again. The threads on the taped hole that the screw for the rotor fits in was stripped. I replaced the entire rotor assembly with a spare from a dead movement and it works perfectly now. Thanks for everyone's inout Quote Link to comment Share on other sites More sharing options...
1680 Posted August 16, 2013 Report Share Posted August 16, 2013 Do you exchange the whole auto winding assembly? Make sure the new one (from the dead movement) is cleaned and oiled propperly. Quote Link to comment Share on other sites More sharing options...

Put the new one on and it spins incredbily smooth free and clear of any interferences. Put the watch on the winder to make sure it's working and it started right up in only a few turns. Thanks for everyone's input. Quote Link to comment Share on other sites More sharing options...
