chrgod Posted August 8, 2006 Report Share Posted August 8, 2006 (edited) Two hours ago, I picked up two watches at the postoffice; A white-faced Navitimer for myself and a black Explorer II for a friend. I opened the caseback just to make sure it was ETA. everything looked good.. BUT, when I turned the watch upside down, the rotor fell straight out! I have never fiddeled much with movements, but as I understand the rotor should be rather straightforward to remove and attach. I tried to push it gently onto the stem/bearing, but it seems like the hole in the rotor is too small to fit over the bearing assembly.. Should I remove the tiny screw in the centre, put the rotor on and fasten it with the screw? I looked on rbj's guide to watch servicing... but it does not go into detail about this. Personally, I suspect that the movement has been badly put together after the modification performed to the ETA2836 to get the 24-hour function... What should I do? All help is greatly appreciated! .. Edited August 8, 2006 by chrgod Quote Link to comment Share on other sites More sharing options...
ubiquitous Posted August 8, 2006 Report Share Posted August 8, 2006 The rotor came off it's bearing. You can probably have it pressed back on, but you should remove the bearing first to do it properly. Or... You can simply use a new rotor/bearing assembly. Easy fix... One screw and remove/install...

chrgod Posted August 8, 2006 Author Report Share Posted August 8, 2006 Thanks Ubi, I dont have any spareparts, so I have to use the old one. I will give a try to unscrew the bearing (centre screw), remove it, put the rotor back on and reinstall. Hopefully without messing anything up.. I am glad I bought Nariikas watch tool set. The tweezers, loupe and screwdrivers come in handy... Quote Link to comment Share on other sites More sharing options...
ubiquitous Posted August 8, 2006 Report Share Posted August 8, 2006 If you don't feel comfortable doing it, you should take it to a jeweler's or watch repair. Pressing the rotor back on may take a jeweler's press. I can also check my box of spares when I get home. I might have a spare rotor assembly buried soemwhere...

chrgod Posted August 8, 2006 Author Report Share Posted August 8, 2006 Everything turned out well! I removed the bearing assembly, and pressed the rotor back onto it. With the bearing assembly removed from the movement, I dared to use a bit more force to press the rotor back on. It was an easy fix as you said. A real man fixes such things himself, and do not wein and send Paypal complains! Quote Link to comment Share on other sites More sharing options...

First, thank you to T/Admin for fixing the search feature, which led me to this post. I had the exact same thing happen to me today on my ETA powered 5513. I am going to attempt to repress the bearing to the rotor using my crystal/jewelers press. Any recommendations/thoughts if any Loctite or adhesive between the weight and the race should be used?

14060 or 16610? Posted June 10, 2010 Report Share Posted June 10, 2010 Neither Loctite nor adhesive required, and actually don't belong inside the watch case. They can flake and cause problems. Press fit is the proper method of installation. Quote Link to comment Share on other sites More sharing options...
redwatch Posted June 10, 2010 Report Share Posted June 10, 2010 +1 - no loctite near the movement. Not a good combo at all. It should press fit in fine. A crystal press will probably work nicely, just be careful not to bend the rotor piece. You might want to push the bearing down in towards the backside of the rotor if you are going to use a press.
