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): www.aerien.ch/f...
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: www.amazon.com...
And storing screws in a Yongcun 24-compartment bead organizer found here: www.amazon.com...
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.

Thanks very much for this. I used it to replace the top cover shutter release wheel mechanism as mine was stuffed. Delicate work, and I had one stripped and corroded screw, but the tutorial here was a great help. Camera is repaired and working again, though it is well used and I have evidence of corrosion internally. But it'll last me a few more years. Thanks mate!

Can you describe how the mirrors are placed inside the glass prism (pentamirror)and how it works.. and what kind of mirrors are used... I like the mirror prism (pentamirror)very much. Thanks

Can I have the part number for the screw @ time 6:41 that is above your thumb, that is in the electric board? Please.

Have you read the manual he linked?

[@ianhenderson6267]

I realise that you made this 4 years ago, but would you still have the screw sizing document that you created @jkenny1 ? I'm in the process of replacing a shutter on my 7D and this would really help.

I was wondering if its possible to dismantle/remove ONLY the top section without having to dismantle the entire unit? I need to get to the flash mechanism, as the 2 small hot shoe "occupancy" pins are wedged inside the hotshoe itself... BUT... I have a Mieke (sp) battery grip which is now STUCK to the camera due to broken spring/gear. so I cannot dismantle the entire camera without destroying the battery grip, which is something I dont want to do. Also where can i get a copy of the service manual you were using there? Thanks in advance!!

[@user-ho2nx8up6d]

Thanks! By the way, do you know any web to but main board?

[@mikelgarcia4958]

Thanks for the video. I don't understand well how to remove de sensor (regarding the warning). Can I get more info regarding this precise measurements from the midframe to the sensor at 3 marked locations?

[@jkenny1]

mikel garcia Yes I forgot to add this link in the description: camerarepair.hu/cmos It describes the procedure to recalibrate from scratch.
