Modern Vespa

Hello!


I've managed to assemble my rear brake and stuff and after I tightened the rear hub nut to 60Nm I tried to put on the castellated crown but it didn't just fit.

Even after I carved out it a bit with my Dremel.


It's a VBC scooter but with a Crimaz driveshaft so the nut is a PX style 24mm hex nut.

That looks like a 22mm nut cage for a front PX axle. There are two types, 22mm and 24mm…

It says rear.

But I got the wrong one?

Should be the right one.

But the one in your hand looks like it's smaller than nut on the driveshaft

Do the 8" hubs have a lock washer?
It seems to me that there should be a crown nut.

What nut size is? 24mm?
Then, as guys said above, your washer seems like it for 22mm nut.
So you maybe need to try https://www.sip-scootershop.com/en/product/locking-washer-brake-drum-piaggio_19442300?usrc=Brake%20Drum%20PX/T5%20rear" rel="nofollow">suitable lock washer.

I bought another one from an Asian bodge source but it seems good. Definitely better than the non-bodge European stuff.
