I'm having a problem with the dress pack on my 7600-400. The bolt head that protrudes "forward" from the joint 6 mounting ring (see the red box outline in the photo below) sometimes, somehow, snags the segmented outer "jacket" of the dress pack, gets into the openings, and then hooks a cable or hose inside the jacket and yanks it out.
I'm not sure how this happens -- so far, I haven't been able to replicate it, even running through the same paths. So I'm looking for alternate ways to attack this: does anyone know what that bolt head is for? And if it's possible to replace it with something lower-profile? Or maybe some kind of rounded cover to place over it?
