RD Trans

[Bloodweiser]

Anybody remember how to remove the shift guides and forks from an RD400?

Manual really breezes over the process, it reads "remove shift guides and forks"
The parts diagram shows some e-clips that aren't visible (only see one)
and some plugs on the drive chain side. Shown here:




are more obviously here:
edit: realize only my thumb is gesturing toward a plug,
while my index missed the mark - it's near my middle knuckle.



Do these get pulled first?
and if so, how and can they be reused?
