So what is that all about in the instructions? It seems you use a torque wrench to see how much force makes the axle turn, then tighten to that spec with at least 4-6 lbs minimum. Why take the wheels and drums off? Too much weight?
Maybe so it's preloaded to the set spec with rotating mass pretty close to what was original. Different drum wear states, rims/tires etc would mean different amount of preload? cuz you'd be turing them too? Writers knew the figures on everything but whatever is variable.
just a guess
4-6 lbs isn't much and if it's inch lbs it's nearly nothing and the slightest brake drag, even the inertia of a wheel would change your reading drastically. That's another of those things I feel out. I could show you how to do it, but it can't be put into words very well.
This isn't one of those wing the target things. If you tighten it too much, there is a piece that crushes, then you have to pull the whole thing apart.
That piece is meant to be slightly crushed when torquing the pinion nut.The problem is that crush piece is now unavailable so you use this alternate method. The part that Moss shows in the catalog is actually just a solid metal spacer.

How does the solid metal spacer change the instruction, if at all?
