Martyd3 Posted February 12, 2011 Report Share Posted February 12, 2011 I've always drilled out the old tube and epoxied the new tube in with JB Weld or Gorilla Glue. I know it's not correct, but it works. I assume the gen tube is press fit in the case. I am thinking that the case would need to be heated to make the hole expand, so the tube can be pressed in place. That is how bushings are press fit in steel. This is an interesting thread on the subject. http://www.chaski.com/homemachinist/...hp?f=4&t=88302 I am a little bit squeamish about heating up my Omega case with a blow torch Quote Link to comment Share on other sites More sharing options...

The original tube is threaded.. and the gen case is threaded as well. The tube screws into the Gen case. Since the rep tube is press fitted into the rep case, the only way to put a gen tube in a rep case is to use the epoxy method. I recommend using Araldite metal epoxy.

Martyd3 Posted February 12, 2011 Author Report Share Posted February 12, 2011 Is there something like this available in the US? Maybe JB Weld? Quote Link to comment Share on other sites More sharing options...

Why can't you tap the rep case? Hole too big? Quote Link to comment Share on other sites More sharing options...
plaifender Posted February 13, 2011 Report Share Posted February 13, 2011 Is there something like this available in the US? Maybe JB Weld? Araldite is available in any u.s. hardware store. Ace, Lowes, HOme Depot.. should all have it. Why can't you tap the rep case? Hole too big? Yes, The rep case hole is bigger than the Gen Tube by .25 mm. That's why Epoxy is necessary.

krpster Posted February 13, 2011 Report Share Posted February 13, 2011 I wonder if helicoil makes one small enough to use for the tube. I suppose you could also make one if you were so inclined. Find a screw the right size and tap the case to match. Then bore and tap the center of the screw/bolt. Then cut off the desired length. Of course it is easy to say Quote Link to comment Share on other sites More sharing options...
Martyd3 Posted February 13, 2011 Author Report Share Posted February 13, 2011 Yea, buy a lathe, find the screw ... it should be easy. LOL The tube it not threaded, btw. Quote Link to comment Share on other sites More sharing options...

I'm sure your wife won't mind Interesting that it is not threaded. They probably just use a piece of equipment that is designed for the job. We do that at work for pressing in engine wrist pins and suspension member bushings. Temperature difference is a great way too. What if you used your oven to heat it up as opposed to a torch? Should be good even heat that way and easier to control the temperature. Meanwhile stick the tube in the freezer. Then they should just slide together nicely. Let them sit and good to go. How are the diameters relative to each other? Quote Link to comment Share on other sites More sharing options...
plaifender Posted February 13, 2011 Report Share Posted February 13, 2011 What model watch are we talking about? I'm confused. @Marty: Is the tube you pictured, Genuine or fabricated by yourself. The GEN Planet Ocean tube is indeed threaded.. but might be because it's a diving watch.. Quote Link to comment Share on other sites More sharing options...
Martyd3 Posted February 13, 2011 Author Report Share Posted February 13, 2011 That's a gen Seamaster tube. It's still in the blister pack. I've installed this crown/tube combo in the past. It's correct for the Seamaster. I think the PO could uses a different crown/tube. Quote Link to comment Share on other sites More sharing options...
cib0rgman Posted February 14, 2011 Report Share Posted February 14, 2011 the Gen tube is not thread you need a bushing. to make it fit properly and keep it waterproof. Quote Link to comment Share on other sites More sharing options...
