alligoat Posted March 13, 2012 Report Share Posted March 13, 2012 Whenever you install a gen tube, there's a minimum list of things to do. 1. Remove the old tube- I use the rat tail file, but an ease-out will also work 2. Tap the hole with the 3.0mm x .35 tap- run it all the way thru 3. You may or may not need to countersink the case hole- using a larger drill bit- this allows you to seat the case tube so that the crown will screw down correctly. 4. If you do countersink, retap the hole afterwards to make sure it's clean 5. Install the tube with some blue loc-tite. i would assume you are then installing a gen crown.

oki Posted March 13, 2012 Author Report Share Posted March 13, 2012 Thanks alligoat Yes, I use a gen crown. Then I understand that it isn´t a "plug and play" work... Quote Link to comment Share on other sites More sharing options...
kbh Posted March 13, 2012 Report Share Posted March 13, 2012 I'd contact BK for more specifics. Often the biggest problem on a gen tube is the "shoulder" on it that needs to be countersunk for it to fit snug to the case even if the threads are the same.

cjjoyce1 Posted March 14, 2012 Report Share Posted March 14, 2012 @ Alligoat - are the threads the same on all Rolex tubes - 5, 6 and 7 series? I had a buddy at a machine shop do my 5512 case. Never thought about it, but having the tap on hand wouldn't be a bad idea. Quote Link to comment Share on other sites More sharing options...
alligoat Posted March 14, 2012 Report Share Posted March 14, 2012 @ Alligoat - are the threads the same on all Rolex tubes - 5, 6 and 7 series? The 6 and 7mm tubes use the 3.0mm x .35 tap. The 5mm tubes use the 2.5mm x .25 tap, as i recall. Quote Link to comment Share on other sites More sharing options...
