Montesa 348 engine rebuild question.

Just putting my 348 back together, I’m a little confused as I’ve seen an exploded diagram of the gearbox and it shows an o ring on one of the rear uppermost casing bolts. I’ve since been told that all the casing bolts need an o ring. None on when I split it.What is the purpose, presumably to prevent oil loss, but where do they go, can find any indentations in any of the bolts to slide it onto. Is it one, or one at each end, one in the middle. Help guys ???

Also struggling to find a torque value for the final drive sprocket nut.  Thanks everyone in advance of the usual abundance of practical advice and experience.
