Yes, 120 ft lbs is also what I use with blue loctite.

Maybe want to give it a tack weld as well just to be sure. :D

I have been using Nord-Lock washers for some important nut and bolt locking applications and it works well. I don't recall what the correct i.d. of the crank nut happens to be..maybe 30mm? Might give the Nords a try next time I have the Jesus nut off. They have several larger sizes..the 30mm sells for about $6 each here in the USA.

Don't know if a 6.8mm wide lock washer would fit..may not be enough crankshaft threads or clearance under the primary cover...probably not.

They would be a good solution. Works well if they can be used.
 
The nut does not have to be jesus tight to prevent it undoing it is jesus tight to stop the sprocket rattling around on the crank splines. Not a good aplication for a Nordloc, they may even cause the nut to foul the outrigger bearing as the two washers of the Nordloc assembly are quite deep when put together. Better off bolocking the nut up tight and using a tab washer.. like the factory did.
