Modern Vespa

I am kitting my 2007 lx150 and upgrading the variator as well with Malossis package.

How do I ensure I have the 46mm clutch nut secured properly?

There were plenty of videos on how to remove it without the several hundred dollar Vespa tool, but nothing on how to tighten properly.

Thanks

I saw a video a few days ago where the guy just tapped it tight with a screwdriver and hammer like tightening a wire connector on an electrical box.
Didn't seem proper to me, but who am I to say.

Was he a healer with laying on of hands?

More like hands and feet...one guy standing on it while the other one worked on it.

That's basically how I got it off. LOL

Now I just need to know how to get it torqued to the right setting.

In a Scooterwest video, it looked like Robot used an impact gun and just hammered until it couldn't take anymore

I made a hole in a board big enough for the 46mm socket to go through. I place the clutch on another board, put my holey board on top, and kneel down, thereby compressing the clutch and preventing it from spinning. I can then torque up the nut quite happily. A dab of Loctite here doesn't hurt.

Do you use a torque wrench? Or just tighten it as tight as it will go?

I just rebuilt my Liberty 150 clutch assembly. I have the fancy compression holder from my Honda Helix days. The tool is worse for wear but it still works as intended. I've seen so many ways, both clever and crazy, to remove that big, shallow nut. Not sure what the torque is but I tend to set mine at 45Nm. I've seen people simply tab the nut with a hammer and punch as listed above and it never came loose. I prefer the correct tools myself. Now, I had to replace a rubber o-ring and the service manual listed a special sleeve that I didn't have. What did I use? A condom to protect the o-ring from catching on the torque slides.

LOL...that's one for the books.

I used to do it up 'hard' but not as tight as it'd possible go - that could lead to stripping the few threads on it. More recently I've used a torque wrench, having acquired a 46mm socket that had a 3/4" square drive for doing VW rear hub nuts. Both will work!
