manuel Posted July 19, 2006 Report Share Posted July 19, 2006 Hi! We all know that changing the tube and crown is a must to do. I have a couple of questions wich i´d like to know, so thanks in advance and hope this post helps another member. In a post of this repair section a member asked if he would replace the crown, Tribal comes in and says this: the TW-case has a tubehole diameter of 2,5mm. You must drill out to 2,8mm and than retap the hole... The Tap has a Diameter of 3mm x 0,25mm pitch.. After reading this, I wonder that a drilling machine should be used. Then what is the good size to start with? Can we start directly with a drill of 2.8mm? After drilling the tubehole, Do I have to use a Rolex tap for 6.0MM Tubes like the pictured below? How do I use it? After retapping, then comes the new tube placement, How does this thing works? What if I have an old style case with a 5.3 mm tube installed and I am planning to put a 6mm tube? Is the hole of this case too little to perform these operations or its just fine? Thanks a lot and Regards, Manuel Quote Link to comment Share on other sites More sharing options...
