Stupid I know, but I did not make a note when I dismantled the clutch. So then, which way round do these parts go? Starting with the tab lock washer which tabs go where? and then we come to the washer with the recess, which way does the recess face? I am guessing that the nut hex goes into the recess is that correct?

Hi,
As far as I know the recess faces inwards, away from the hexagon
I have seen some with a recess and some without???
I think the purpose of the recess is to apply clamping force to the inner drum and not just the shaft adapter ???

I agree - recess to drum.

Regarding the tab washer, the large tab hooks up on the flat of the adapter/drum. The two smaller tabs are bent down on the nut
