sneed12 Posted January 30, 2010 Report Share Posted January 30, 2010 I have two ETA movements in pieces on my desk right now. Both needed service after I was a lazy idiot and used a pin instead of a screwdriver to get the stem out. One is an ETA 2836-2 with GMT instead of day/date. I got it apart and back together and I thought I had all the keyless stuff in the right place. However, when I install the stem and try to set the time, it seems like some gears aren't engaging fully. I get a crunchy noise when I turn the stem one way, it slips when I turn it the other way. In one click seems to turn the date and GMT wheel, but with the strange noises I wasn't going to play too much with it. The other movement is also an ETA 2836 but without day or date wheels. It had the same problem, and I got it apart and back together without issue, but it no longer handwinds. It hacks, the datewheel turns in the first position, and the hands adjust in the second position, but in the fully-in position it will not handwind. I desperately need a picture of a 2836 taken apart, so that I can be sure that I've got everything back where it goes. I found the flash tutorial of the 2892 and it's been really helpful, but it's not exactly the same. Quote Link to comment Share on other sites More sharing options...
sneed12 Posted January 30, 2010 Author Report Share Posted January 30, 2010 The GMT movement definitely has something installed incorrectly in the keyless, because it makes the noise even when I take off the gear that engages the hands (sorry I have no idea the names of these things). As far as I can tell, though, everything is the same as the other one. I think I also had that gear in upside down, which was why it wasn't engaging the hands in the 2nd click position, I think I have that fixed now.

sneed12 Posted January 30, 2010 Author Report Share Posted January 30, 2010 Found a tutorial thread, seems to confirm that I have put everything together right. Odd. Can anyone explain to me in detail how the handwinding mechanism works? Quote Link to comment Share on other sites More sharing options...
azerbyjam Posted January 30, 2010 Report Share Posted January 30, 2010 The problem with your second movement sounds like the spring on the keyless works cover isn't fully engaged against the yoke, see HERE for a fuller explanation. Quote Link to comment Share on other sites More sharing options...

The problem with this one will be the spring that holds the winding gear against the crown gear i dont have a photo but here is a shot from the tech info.

That did it, thanks. Now just to figure out the other one... Quote Link to comment Share on other sites More sharing options...
sneed12 Posted February 1, 2010 Author Report Share Posted February 1, 2010 I've sorted out everything on the one movement, and it's back in a watch and running... like a Swiss watch The other movement (the GMT) everything works except it's not hacking anymore... I'm hoping it's a simple problem like the first one, something slightly out of place. I've sorted out the crunchy noise (setting gear was in upside down) and all of the GMT bits are back where they go, and the handwind is working.

FxrAndy Posted February 1, 2010 Report Share Posted February 1, 2010 the hacking lever will not be seated in the recess on the castle wheel. Quote Link to comment Share on other sites More sharing options...

sneed12 Posted February 3, 2010 Author Report Share Posted February 3, 2010 Got it. Both movements are back to 100%. All it cost me was a scratched dial but I have another one on the way. Quote Link to comment Share on other sites More sharing options...
