1D Mark IV repair question

I just got my Mark IV back from Canon repair, and I have a question about what they did. Here is the text from the letter I got with the camera:

Your product has been examined and it was found that the part required lubrication. The unit was cleaned and checked. Adjusted exposure & focus, C-MOS, WB & Shutter Speed. Cleaned C-mos and Checked all to factory specs. Product functions were confirmed.

Then below that, in a table, was the following:

Part Description - Part # - QTY
WASHER, FLANGE BACK - CB3-0060-000-003 - 1
WASHER, FLANGE BACK - CB3-0060-000-005 - 2
WASHER, FLANGE BACK - CB3-0060-000-008 - 2
WASHER, FLANGE BACK - CB3-0060-000-012 - 3

(Sorry, I couldn't get the columns lined up...)

Just wondering what the "WASHER, FLANGE BACK" is, why there are 4 different part numbers, and quantities.

The camera works great and all is well, just curious on the part(s).

Thanks!!

The lens mount has to be very precisely distanced from the sensor, so shims are used between the mount and the chassis. Various sizes are used to make the required thickness.

they must have had your camera in bits to get to those parts they added

very neat illustration, where do you get stuff like this?

Holy crap!!! Lol

Yea, where do you get that stuff?

And if you think about it, they got it this past Tuesday morning, and it left the factory Thursday morning. How in the heck could they do something like that so fast?

Amazing....

From the 1dm4 spare parts catalog

here is the link

Well let's hope nobody need that...

It's actually not that difficult, a good 8 hours with a tech that knows what he is doing. (and it's a 1d, chances are the tech is one of the more senior at the repair facility.

I used to be able to replace the lens and recalibrate an Olympus FE220 (cheap P+S) in 20 mins, rebuilding a water damaged mju/stylus 1030 or 850 used to take 45-90 mins.

The bit that takes the longest is actually the cleaning up, sand, spilled soft drinks, and rust in water damaged cameras (on the lens mount brackets etc) takes ages to clean off, and can easily double the length of time a job takes.

Yea, guess you're right... I would figure a senior tech would be working on a Mark IV. I was a computer tech and I could put a server together from parts, and get the server OS installed with all the bells and whistles, ready to be put into production in about 8 hours (I'm sure there's better, but darn good for me...).

I can just imagine what the Canon techs see on a daily basis, makes them scratch their heads sometimes I figure...

Yea we had days like that, (I was a tech at an Olympus warranty agent for a bit over year)
In the early days of digital the boss fixed a camera, and recovered the memory card for a client, upon recovering the card, he found the reason for the "liquid damage" of the camera, the last frame was a woman urinating on the camera.


Explaining the reasons for a "pihc" or "ID ten T" fault were always fun too.
(pihc is similar to pebcak "problem is holding camera" and ID10T kinda explains itself)

And here I thought the broadcasting industry was the only line of work where the ID10T issue was well known...

There's also that dreaded ONOFF interface!

having had a 1D MK II in bits, I can say a good tech should be able to get the sensor off in less than 10 minutes...

how long the adjustment process takes however, is anybody's guess.

I appears that the tech was very thorough with this camera.
Which repair facility was it?

Jamesburg, NJ. I always send my gear there.

getting it apart is easy, its getting it back together without having bits left over thats the hard part

and the adjustment process would take a while, if i remember correctly it uses a 50mm f1.8 attached to the lens mount
