How do you hold the clutch to get the big clutch nut to the right torque before you reinstall it on a scooter?

Are you asking about the outer clutch nut on the clutch bell or the inner flat nut that holds the clutch to the driven pulley system?
In both instances, I use a strap wrench to hold things in place when tightening the nut and I also use blue LockTite for both.
I don't use a torque wrench on the inner flat nut because I don't have a socket that big so I actually clamp that nut upside down in a bench vise and use the strap wrench to turn the whole clutch assembly instead of turning the nut.
I have also used a Swedish-style Stilson wrench in combination with a strap wrench for the flat inner clutch nut.
This one has adjustment that keeps the jaws parallel to each other and can sit nice and tight against the flat nut.

Hi Tocsik: it would be the inner flat nut.

I use a large crescent wrench. Clutch on the left. Wrench in the right. Holding the 2 together with your hands. Point the handle away from you, strike the handle on something hard 5-10 times and it will free up. There is a youtube video but I can't link it on my phone. I

The OP was asking about re-torquing, not removal. Probably appreciates the responses about removal, though.
Does anyone use a torque wrench on the flat fixing nut?

Ah I missed that. I started off by marking it and then reinstalling to the mark. Now I go by feel.

Hope you got the clutch nut sorted out.
I'm following-up to make sure you don't experience what I went through when that same nut backed out a bit on my scooter:

I think it's happened to a couple other folks here on MB.

Inner clutch nut
Thanks Tocsik and agrogod! I used the large crescent wrench method, along with stake marks and a little blue lock tight. I also cut a hole in a piece of ply wood so I could use my knees to compress the spring. Everything worked grate! Thanks again for your help. Issue31

The board with the hole is the best method for compressing that damn spring when you work alone! Especially anything over the stock contra spring stiffness.
Good job, man!

I'm fairly certain this thread title is certain to be added to the "double entendre" thread.

I've got a stiffer contra spring to install. I was thinking of doing the board-with-a-hole. Seemed a lot easier.
