Thanks to Media Digital Photo
here's the the Canon EOS 30D Parts Catalog: Canon EOS 30D Parts Catalog
Also available from our servers HERE
Just so you know, I've scoured the web for these documents and I can assure you that right now these are the only two locations readily available. I actually had to email Media Digital Photo for the link. Many many thanks to Marcel van Daalen of Media Digital Photo for sending me the link.
I'm using this as a helpful guide to disassembling my 30D to replace the shutter assembly.
**Update, I've reached the shutter assembly (just about had to completely tear-down the 30D. The exploded parts diagram is a god-send. I made several calls to camera repair shops and most wouldn't just sell parts but the last shop asked why I just wouldn't call 1-800-okcanon ? He said if they did sell the part it would be marked up. Sure enough, I called and they had to give me another 800 number for internal parts (I'll list it later, but you can call 1-800-okcanon and get the number eaisly) and the shutter was $33 from Canon whereas it was $50 elsewhere.
So this got me thinking why not just order a new shutter release key (button)...at just $6 I did and I ordered the double-sticky tape for the two grips ($.70 each) and a few other wear-n-tear parts. Total shipped was $44, less than the shutter ass'y alone from a repair shop.
Stay tuned, I will start a video demo from a fully tore-down (well almost fully) and restoration of the shutter and other components.
