What is the required special socket size for the castellated swing arm nut ? 42MM ? 50mm ?
Thank you kindly

Just measured the 2 I have------------ one is 42mm- older 5sp imput hub nut, what I use one is 40.5 mm- new for swingarm on CARC's, thinking it may be better. The older one is what I use caust it has a washer & nut I welded on to torque hub's on, new one just has a cross bar. Money not well spent, but prongs are wider(different slotted nuts)

You can also use a 'C' spanner to preload the collar easily enough. All it needs to do is remove the end float from the bearings. It's not meant to be tightened up to buggery.
