I mean on the nut where the loctite is being applied in this picture. Is this the nut you mean?

Thank you so much

Yes, the vario nut.
Actually the factory manual says 35-45Nm, and 45-55Nm for the cluth nut, which is smaller than the vario nut. These are indicative values, I apply 50 front/50 rear since ages and its ok. With these torques you don't need loctite here. Better to get the proper torque than use loctite on a poorly tightened nut...

I have a question, i know nothing about torque so what is torque and how can one measure it and what tool is needed?

Torque is a turn or spinning force, that you apply on the nut to be sure it won't move. To measure it you need a "dynamometric" key, or torque key, you can get it on eBay or in auto stores.

We call them torque wrenches over here:

However, with the vario and clutch nuts, the easiest way to take that off and put it on is with an impact wrench, since the thing you are fastening it to will spin if it isn't held in place. They have impact wrenches that have torque settings on them:

Unless you are a mecanic, better to use a Buzzetti tool to block the variator and a torque wrench to get the proper torque. By the way this torque wrench you showed is oldschoool !

Thanks for that, helped a lot. Will have to see if i can pick one of those up somewhere.

Try to get a "Click type" (see on the wikipedia page) on eBay, you should find one for 30 dollars. Then a Buzzetti variator blocker, 10 dollars.

Seems to me you can use a 1-1/4 combination wrench to hold the large nut outside the variator nut. If the vario nut is not tightened properly the starter gear behind can run loose and damage the starter and gears. You laos need to make ceretain everything is seated correctly and look at the amount of threads sticking out past the nut to make sure everything is on all the way. If you tighten it with the splines not aligned correctly it can and probalby will slip at some point and come loose, possably leaving you stranded.
