Canon 7D Disassembly

I thought this would be a simple shutter replacement/lens contact replacement based on the description, but it turned out that this camera had brutal salt water damage/corrosion. I stripped it down to the shutter anyways to see if there was anything obviously wrong with it, and cleaned up the various boards/components as best I could. WARNING: Do not remove the CMOS sensor unless you have taken precise measurements from the midframe to the sensor at 3 marked locations, otherwise the factory CMOS/AF calibration will be lost requiring a very complicated procedure to get it back! I made the mistake of doing this, though I ended up selling this camera for parts anyways and the CMOS was not testable in the camera's condition. I am using the 7D parts catalog found here for reference, I highly recommend printing a copy and following along during disassembly (I also make notes of anything special about the screws e.g. color): http://www.aerien.ch/files/EOS_7D_Par... I am using the Moody Tools JIS driver kit found here for disassembling the camera, and a Wiha #759 multi-bit driver (with T6 bit) for removing the CMOS: https://www.amazon.com/dp/B004PGO1T6 And storing screws in a Yongcun 24-compartment bead organizer found here: https://www.amazon.com/dp/B01KGQDNOW I write in the various screw sizes in the compartments (M1.7x2,3,4,etc.) and check screw sizes against a to-scale printout that I drew in Fusion 360.
