JBM37404 Posted October 28, 2009 Share Posted October 28, 2009 As in the thread title. Currently about to go DCC and am sitting here with a Bachmann class 40 which does not wish to leave its chassis. There are 8 screws underneath of which only 3 have unscrewed sucessfuly. The screw driver is the right size but this is becoming very frustrating! Anyone had any similar problems and overcome them?

Yes, sounds like the threads have stripped. What I did was try to exert some upward pressure on the bodyshell with one hand while unscrewing with the other. Worked for me on a number of Bachmann locos although in most instances only one screw had become stuck. An alternative fix would be to junk the mis-shapen Bachmann shell and replace with a correct proportioned lima one! Link to post Share on other sites More sharing options...

34theletterbetweenB&D Posted November 5, 2009 Share Posted November 5, 2009 If they are like this from new, return to dealer is one option. As a DIY fix, if convinced that the thread is terminally stripped a technique that has worked for me is to truly strip the threads by putting the screwdriver bit in a power drill and giving each screw a fifteen second whizz; then either let the chassis drop out under its' own weight, or pull it out. The location holes can be refilled and redrilled and tapped if desired, but most Bach diesel bodies stay put without screws, if you don't need to regularly handle them.

Paul-H Posted November 5, 2009 Share Posted November 5, 2009 Is it the thread that is stripped or the head of the screw, its easy to think you have the right size screwdriver when you actualy have the wrong size and then strip the head. Link to post Share on other sites More sharing options...
Horsetan Posted November 7, 2009 Share Posted November 7, 2009 ....An alternative fix would be to junk the mis-shapen Bachmann shell and replace with a correct proportioned lima one! Even better: use the centre body section from the Lima shell, and graft it in between the two Bachmann cabs. Just like this one Link to post Share on other sites More sharing options...
