ceejay Posted January 25, 2015 Report Share Posted January 25, 2015 Welcome Alex. GenTle is a very good student, me too. We like Horology Tell him how to do it and I think he will have a damn fine go at it! Link to comment Share on other sites More sharing options...

GenTLe Posted January 25, 2015 Author Report Share Posted January 25, 2015 (edited) Alex, this is a test movement: partially assembled, got for free from a member of the other RWG. I needed to unassemble the stud and regulator to take out the Inca spring that I need for another (good) 7750 that has a broken lyra spring. No, couldn't just swap balance assembly as the co_k is different and doesn't fit in my other base plate. Now, before going to work on the good one, I want to learn on this test one. Cheers, GenTLe (Alex too, that's my real name) Edited January 25, 2015 by GenTLe Link to comment Share on other sites More sharing options...
ceejay Posted January 26, 2015 Report Share Posted January 26, 2015 I think the first think you need to do is get the balance wheel with attached hairspring out of the way. You don't want to damage that any further Put a piece of rodico under that fine regulator arm to hold it in place while you remove and turn over the balance c ock. Then you need to unscrew the stud retaining screw that holds the hairspring stud in the balance c ock. That's the screw at the 7 o'clock position in your photo. only turn that screw half a turn at a time, until the stud is released. You do not want that falling out! Where the terminal coil of the hairspring passes through the regulating pins, the 2 brass pins at the 8 o'clock position there is usually what's called a 'boot' that sits across the 2 pin to prevent the hairspring from jumping out of the pins. This 'boot' will rotate. They sometimes have a tiny slot in the top to get a screwdriver in, they sometimes have a hole in the side to insert a tiny needle etc. or grip it with a pair of tweezers and turn it a quarter turn and lift out the hairspring. Remember to do the stud retaining screw up as soon as you have the stud out. I can't help you with the refitting the regulator arm as I haven't done one yet. But get the balance and hairspring clear first Good luck. 1 Link to comment Share on other sites More sharing options...
POTR Posted January 26, 2015 Report Share Posted January 26, 2015 Those are a press fit. Usually using an appropriately sized punch from a staking tool set, by hand, to apply pressure evenly and avoid damage. You will need to adjust and regulate after. http://www.timekeeperforum.com/forum/threads/adjustment-and-regulation.21105/ Link to comment Share on other sites More sharing options...
GenTLe Posted January 26, 2015 Author Report Share Posted January 26, 2015 Great advice CJ and POTR. As soon as I will have some time and I will not be [censored] tired from office I will give it a try:) Link to comment Share on other sites More sharing options...
alex waller Posted January 26, 2015 Report Share Posted January 26, 2015 Sorry my bad, Im just so used to people with no idea what they are doing really messing things up! That probably wasn't the best first post I've ever done either. Anyway good luck, the above advice is sound Link to comment Share on other sites More sharing options...
POTR Posted January 27, 2015 Report Share Posted January 27, 2015 No one ever knows what's going on around here... That's why it is so..much fun. Link to comment Share on other sites More sharing options...
GenTLe Posted January 27, 2015 Author Report Share Posted January 27, 2015 No problem Alex. Quite often I also have your type of reaction within my real job Link to comment Share on other sites More sharing options...
GenTLe Posted January 28, 2015 Author Report Share Posted January 28, 2015 This thing is a bi_t_ch!!!! I managed to take out of the way the balance and its spring, putting back the hair spring stud holder on the co_k is easy, but the coarse and fine regulator rings are BAD to put back around the jewel holder... REALLY bad, they are! Link to comment Share on other sites More sharing options...
POTR Posted January 29, 2015 Report Share Posted January 29, 2015 The amount of pressure, or force one needs for many things takes time and practice to develop feel and technique. Link to comment Share on other sites More sharing options...

Good luck with this i did one on a 6497 and its a pain to do Lol, the balance co_k was not fitting on my plate, so I had to do that in order to take out the spring (main reason I was searching it) without breaking it Link to comment Share on other sites More sharing options...
