Whether mine is correct or not Phil, but I've assembled it in good old Haynes terms...assembly is the reverse of disassembly
In order of assembly....ratchet with bush slid inside, bush will protrude.
Spring, then lockwasher which, to my mind, doesn't really lock as you say.
Then nut.
I got a new spring just in case and you can certainly tell the difference!
The lockwasher seems to be more of a friction fit as it doesn't appear to lock into the bushing.....unless I'm missing something?
Pretty sure someone will know.
Problem I'm having at the moment is that the ratchet teeth and the quadrant teeth don't initially mesh properly unless I rock the bike. I've profiled the first quadrant tooth but it doesn't seem to have helped.....onwards and upwards!
Pete.
