As you can see from the time I posted this Im on nights and maybe not seeing correctly but does the washer on my photos look a hell of alot bigger than yours ? and from what I remember it isnt dished in anyway all there is is a dished washer under the nut to hold the clutch on to the shaft ?
could the size make any differance ? as you see it does cover both parts of the shaft ?
Ill look at my clutch yet again when I get up and check it against your measurements and photos.
it looks like your clutch assembly is about the size of mine.
Thanks again for taking your time to photo your engine its much appreciated as I would be realy stuck without your advice and help
