Good afternoon everyone - troubling you for a bit of help 🙂

Picked up a little Omega to work on as a Xmas present for my mother. 

First problem I came across was removing the stem, as I was used to the push down or screw type of release mechanism - little did I know this was a combined one, unscrew and then push down to get the job done. 

But the main issue I had, was removing the driving wheel, as I believe this was glued on (didn't think of leaving it on and cleaning it like that); I used the Bergeon presto tool but unfortunately the third wheel pinion snapped. (second photo)  For future use I picked up a Bergeon 6016 as I feel it give me a bit more control. 

So, off to the internet I went, and after some time I received my parts 630-1240 third wheel with long pinion and 630-1249 driving wheel over third wheel. 

Movement is back together and working nicely, third wheel poking out as intended, but I can't push the driving wheel back in - I know it's a friction fit, but it should require around the same amount of force as fitting a seconds hand correct? To get it in half way already required more pressure than I was comfortable applying, especially as I could end up snapping the pinion again. Should I pull out my cutting broaches or order a new 630-1249 driving wheel? 

Many thanks! 

L.

Hello L.  Welcome to the club. 

I heard some folks have had better luck using a staking set to drive the min wheel home with. 

Following your thread with interest.

Good luck.

Thank you good sir 🙂

Have been contemplating on this - the staking set would be used basically to apply even pressure on the wheel? 

If that's the logic, then a fixed hands setting tool should work as well (to ensure even distribution of pressure when pushing down). 

Just looking at the least expensive option to move this forward, haha.

Hello L. 

I am not sure if use of staking set is a sure approach, have just heard about better success rate by its .

Pull streight up with presto tool is about the only advice you can expect here, yet facts are removal/repalcement of min wheel is risky.

I think your right bout the logics of even pressure distribution.

I think you'll find that a lot of the screw type you have to push a little bit. It depends on the parts on the other side but it's not just unscrew pull the stem out a lot of times you have to hold the screw down.

You should build the use your hand press or staking said or basically anything that puts an even downward pressure. As to how much force is required that is the interesting question? Did you try flipping the wheel over and seeing if it goes on better the other direction. Usually they always seem to be facing one direction. Conveniently the instructions don't tell you which side goes down. Then yes there is a possibility that you may have to open up the whole a little bit. But I would be extremely careful with doing that as it's easy to go too far.

Right gents, all sorted - picked up another 630-1249 driving wheel which went in much easier. 

Used a regular hand fitting tool, there has been some slight bending when installing, but luckily no damage! Need to get a hands press for future use. 

Also keeping an eye on some Ebay staking sets just in case 😉

    • it would be nice to have the exact model of the watch the or a picture so we can see exactly what you're talking about. this is because the definition of Swiss watch could be a variety of things and it be helpful if we could see exactly the watch your dealing with then in professional watch repair at least some professionals they do pre-cleaned watches. In other words the hands and dial come off and the entire movement assembled goes through a cleaning machine sometimes I think a shorter bath perhaps so everything is nice and clean for disassembly makes it easier to look for problems. Then other professionals don't like pre-cleaning because it basically obliterates the scene of the crime. Especially when dealing with vintage watches where you're looking for metal filings and problems that may visually go away with cleaning. Then usually super sticky lubrication isn't really a problem for disassembly and typically shouldn't be a problem on a pallet fork bridge because there shouldn't be any lubrication on the bridge at all as you typically do not oil the pallet fork pivots.  
    • A few things you should find out before you can mske a decision of what to do. As Richard said, what is the crown and all of the crown components made of . Then also the stem .  The crown looks to have a steel washer that retains a gasket. So be careful with what chemicals you use to dissolve any stem adhesives or the use of heat. You might swell or melt the gasket unless you are prepared to change that also . The steel washer maybe reactive to alum. Something I've just used to dissolve a broken screw from a plate. First drilled out the centre of the screw with a 0.5mm carbide . Dipped only the section that held the broken screw in Rustins rust remover. This is 40 % phosphoric acid. 3 days and the screw remains were completely dissolved, no trace of steel in the brass threads. A black puddle left in the solution.
    • I suppose this will add to the confusion I have a roller jewel assortment. It lists out American pocket watches for Elgin 18 size and even 16 size it's a 50. But not all the various companies used 50-50 does seem to be common one company had a 51 and the smallest is 43. American parts are always interesting? Francis Elgin for mainsprings will tell you the thickness of the spring other companies will not even though the spring for the same number could come in a variety of thicknesses. But if we actually had the model number of your watch we would find it probably makes a reference that the roller jewel came in different dimensions. So overlook the parts book we find that? So it appears to be 18 and 16 size would be the same sort of the arson different catalog numbers and as I said we don't have your Mongol know which Log number were supposed to be using. Variety of materials garnered her sapphire single or double but zero mention about diameters. Then in a section of rollers in this case rollers with jewels we do get this down in the notes section Roller specifications but of course zero reference to the jewel size. I was really hoping the roller jewel assortment would give us sizes it doesn't really. But it does show a picture of how one particular roller jewel gauge is used  
    • Seems to still do it through my mobile data, I use an android phone almost exclusively, but I'll double check it. Thanks mark Strange, I'll try my laptop that utilities edge. I've been on site half hour since I got home, it hasn't done it yet. Thanks John
    • At work, I'm on MS Edge, not through chose, on my phone, chrome, no issues with either.
