The whole shutter assembly comes out from the body in one piece, which is very handy, because by reinstalling lever and dials manually you can actually test-shoot it without it being mounted on the camera. With all dials off, the shutter should function as if T was selected.
DISCLAIMER: I am not professional, this is just what I've done:
- put very small drops of alcohol on bearings
- cock & fire some times, until you see old lubricant come out
- clean the old lubricant
- use a needle tip + suitable oil (I've used sewing machine oil) to re-lubricate, DO NOT OVER-LUBRICATE
I haven't taken the rollers out from the shutter frame, because mine still worked smoothly and without noise. However, the note I posted above contains some preliminary values for tightening.
Use a file to create a special round-tip screwdriver to get fast-speed dial screw out without damaging it, this helps with two other top screws too. While you have the shutter on the table, it's also really easy to check the condition of the shutter. Also, this is a good opportunity for replacing light-seals and mirror foam.
