Reusing photos from way earlier...
Yeah removing that top panel gave access. The shutter blades are all riveted to their linkage arms and didn't seem super ready to jump out, but i'd still try be cautious about not moving them too much or tipping the shutter over with the cover removed. Also watch out for the lever to actually fire the shutter since it could be a mess if that tripped with the cover off.
A few big things come loose. There's a shim/ leaf thing on the left that comes out, there's the reinforcing panels on the outside of the shutter's cover that can come loose, and in that photo is a bit of white tape i'm fairly sure was from the spool of a roll of film and not original to the camera - there were a couple of torn sprocket holes in the body too.
The tricky part though is that spring on the right that comes loose. The longer leg rests against one of those posts (take note of which one before opening it. It looks like the lower of the 2nd post from the bottom but it's not super clear in the photo) and the hook attaches to the linkage arm. There might be a way to trap it and hold it still before removing the cover, like a blob of blu tack... although i'd worry about that fouling things or depositing unwanted oils. It's fiddly to reattach though.
The method that worked for me was to unhook the spring from the hole in the linkage, position the long arm around where it's supposed to go (on the outer edge of the post), put the cover back on after replacing the bumpers (a tiny bit of temporary tape helped keep that one shim/leaf thing in place), then trip the shutter since that moves the hole in the linkage down and to the right and closer to the edge for access. Then using whatever tiny hooks or tweezers you have available, try fish the spring's hook into it's hole. It took me a few tries since I kept accidentally flexing the top cover enough that the spring's long arm was able to escape over the top of the post it rests again. It was a real fiddle.
It's a shame they didn't just put a little notch in that post to catch the spring. But I guess the whole unit was never supposed to be opened like this.
