how to remove shell from GP40 Sound Value

[drm227]

I want to remove the shell from my Bachmann GP40 DCC Sound Value locomotive (model #66304).  An older post (http://www.bachmanntrains.com/home-usa/board/index.php/topic,24271.0.html) says to:

"Pry the fuel tank off and you will find 4 screws underneath, remove them and pull the shell straight up."

But on the Sound Value GP40's the speaker is housed in the fuel tank.  So it seems like there must be a different procedure.  I don't want to damage the speaker.

Bach Man, can you tell me how to remove the shell from my locomotive?

Thanks,
Dennis

Since it's a sound unit, there will be 1 or 2 screws that hold the fuel tank cover on. Remove those. There should be 2 screws holding the shell on. Remove those. Remove the screws holding coupler covers on . Remove the covers and couplers. Remove the shell.  Joe
