Vespa vbb clutch

[achi]

Hey guys, i recently started doing an engine rebuild on a 67 vbb that sat for a few hard decades in the mud and the rain, and i wanted to ask, first of all is there a service/workshop manual that i can get? Pdf? And also what or where can i see the minimum size for the clutch friction plates? Before i order new ones? What are the specifications? Thanks..

Regarding a clutch rebuild, just bite the bullet, get plates metal and corks, springs and thrust washer or alternatively you can by a full unit, same as early px (22cog i think)
Dont forget new tab washer, castle nut # and thrust plate, plunger, woodruff key
# you can buy a flanged nut to replace the castle nut.
If you choose the tab washer and castle nut do NOT buy cheap as they are soft. Buy SIP

Plates are same as early px if you choise to rebuild existing
