Hi All

I'm still a beginner reassembling an AS 2066.  The stem has three positions: wind, date set, and hand set.  Mainspring and bridge are in but not the click or the pallet fork.  When I pull the stem to the third position and turn the mainspring will also turn either way depending on crown turn.  Should it?  Below is the repair instructions (would love to find more like it).

Thank you

Charlie

I think it may have something to do with what they are calling the "large driving wheel & notched set wheel" which is below.  It's two gears on one pinion and both can move independently.  My guess is that the low gear (forefront) sets the hands.  While that's occurring the top gear, which is part of the train wheels, is also moving.  My guess is that should not move.  But what's to prevent it?

Their stuck in rodico.  This part is "new" from the supply house.  I tried to remove the gears on the old one and lost that clip at the end.  Now I see that the repair instructions say "cannot be disassembled, available only as a unit".  I did oil the seam between the two gears.  I suspect there's still too much friction.  If that's the cause, how do I remedy it?

Should have some friction . So do not over oil. Just a tiny bit so it's not metal to metal . As that will destroy the friction in no time . That is instead of the cannon pinion . AS 1950 and zodiac 70 and a lot of other movement use the same construction . Haven't tried it without the pallet fork. But i think it can have that effect if you try to wind it up. Rotor only turn one direction when you put it back . And the other way it will freewheel .  So put the movement back together and you should see that it works fine.

Not sure what you mean by this. 

I put the pallet fork in and there's no power in the main spring.  When I set the hands that torque goes through the wheel train and causes the pallet fork to shift back and forth.  Should this be the case?  Seems that if completely assembled that would cause a problem.

      Looks that way, if it had any amount of significant jewel count it would say so on the dial.    Looks that way, if it had any amount of significant jewel count it would say so on the dial.  Same answer as Mike regarding the dial, its often just a slapped on name of a retailer but i thought you were way above this understanding Pete ?

      Light naptha is what you need to be looking for. The carbon to hydrogen ratio is high with heavy naptha, it doesn't evaporate as well as light naptha and is prone to leaving more residue. Try tom's suggestion of the mirror test.

      Its a big item Michael and a lot that could go wrong with the process of getting it to its new location. I once helped install one of these units into a conservatory that i had built. It was big and bloody heavy and took six of us to get it in safely. If you have sliding doors and you need to remove the whole frame then that may or may not go well. But i would advise getting a professional in if you have little knowledge on the installation of them. The glazing of the doors could well be 6mm laminated glass which again will be heavy very heavy if the glazing units are big. The glass would also need to be set up and packed correctly to open the doors properly more so if they are unframed and the sliders are upvc. Seems a shame but if no one is biting and that may be due to having no warranty i guess the only takers might be someone that installs them for a living and knows how to repair. If its fibreglass just be careful, i sometimes have to cut fibreglass baths out and they are nasty to work with . Thick gloves are definitely recommended,  not fun picking out fibreglass spells two days later that have started to go septic. Good luck with it all matey.

      I don’t know anything about this product, however assuming you have it if you put a drop on a mirror or piece of glass lying flat on a table and leave it to evaporate if it leaves any sort of residue it is not really suitable for watch part cleaning.   Tom

      Well I put the spa on Gumtree (selling service) to try and sell it as it only needs a recirc pump to get it going. However, it weighs circa 250kg, so there's 4 fairly strong guys, and I would have to remove the sliding door in the room completely to be able to get it out, as well as clearing out a multitude of potted plants and the Alfresco outdoor setting to be able to get it out. Then move nearly everything in the back of the garage to be able to push it through to the front of the house. I would also need to hire furniture skates to be able to shift it around as carrying it is out of the question. Then someone would need a trailer to get it to their place as you won't get it on the back of a ute. So, the only answer is, out with the reciprocating saw and cut it all up into manageable pieces. Crying shame as it is in really good nick. I was only asking $1,500 and only got two bites, but it would only take something to go wrong with removing the sliding door etc that everything I make on the sale could go out the door on repairs etc. It would have been nice to be able to turn it into tools etc, but que sera sera. I don't know about the rest of the world, but there just seems to be very little interest from people wanting to buy things secondhand.
