Hi BB,

In having a look at your prob from what has been posted in your pics and Gizmo's information (which is excellent), I have come to this conclusion:

(1) From your pic with the green cover and rusty washer and flywheel nut with no circlip groove visible, I surmise that (as Blue said in his reply) the washer is an interference fit with the nut and if you soak the area in WD or equivalent, place a small thin drift in the flywheel puller holes from the inside of the flywheel...tap gently in all three holes, the cover and washer will release. wink
My reasoning comes from the left hand illustration in Fig 1 (Page 6) of Gizmos post, where you can see the flywheel in-situ with the flywheel nut still fitted

I believe also that the circlip only needs to be removed if you are replacing the flywheel nut for whatever reason.
Hoping this helps,
cheers
