Anyone have a list of the engine torque figures handy to post for present and future reference? I find random mention in the literature with some disagreement. The moment finally approaches for assembly.
Thanks,
Mike
Do you have George Cohen's…

George covers most....
......but a few missing. I sure wish the gaps in his notes would reappear. A great resource.

The fact that Norton never…
The fact that Norton never listed them in the 1930's is probably connected to the Wikipedia listed fact that the torque wrench was not invented until 1931! They relied on the mechanic using the correct length hand spanner for each nut, and not a single length socket set bar handle for all (which makes it all the more likely that nuts will be overtightened).!!

That feeling of the fastenener just beginning to strip....
......is matched only by the sudden appearance of a flashing red light in the rearview mirror.
The gem of George Cohen's notes:
"Besides having a decent set of spanners, a strong vice, a big hammer, an impact wrench (preferably air power to about 150 ft.lb. but ONLY used for undoing nuts) and a few pullers; you really need a lathe, a milling machine, cylindrical and surface grinding, all types of welding equipment, a spark eroder, surface hardening equipment, and about 50 special tools, jigs and fixtures to do the job properly!"
Amen

I'm finding discrepencies .......
......on torque numbers for the camshaft bevel nut. In George's notes he recommends 70 ft lb but he is quoted here:

recommending 200 Nm or about 140 ft lb. Seems like a lot to me. Thoughts?
Thanks,
Mike

Mr ' Racing Vincent' says 55... just to add to confusion.

Do you have George Cohen's assembly notes? That's the only data I remember seeing. I think John de Kruif posted them on the web.
