I had accidentally dropped the EF17-40, the lens still fully works as it zooms, auto focuses, and takes images just fine.
The minor damage occurred with the mounting interface of the metal lens mount to the fiber reinforced phenolic type material base within the lens, where 2 of the 4 mounting tabs have fractured. By removing the 4 mounting screws, I can partially lift the metal lens mount enough to gain some access to the fractured surface, and I plan to use some high strength epoxy to reattach these two broken tabs. However, I have not figured out how to remove the metal lens mount completely off the lens, this will allow me to make this repair in the most convenient manner. The part I am having problem with appears to be the portion with the electrical contacts, there are two small screws on the side of the metal lens mount screwing into the plastic piece with the electrical contacts, but removing these two screws still does not allow the metal lens mount to be completely removed. Does anyone know what I have to do to fully remove the metal lens mount? Is there any service manual or exploded view diagram available for this lens on the web?
