V2 Diff rebuild + Gear Ratio Swap

Is the locking ring bottomed on this step? If it is then one cannot tighten the ring for preloading the clutch.

No, it sits slightly higher than the end of the threads. there is a spring washer between the locking ring and the top of the pump, as you tighten the collar it compresses it a bit, so the pump is fully seated in the carrier case.

"the clutch pack is no thicker than that spacer gear"
Pic above seems to show the spacer gear is below the top clutch stack shim. No?

"Now, since I was not able to undo the ring gear, I had to pry on the bearings, dont do this if you are not replacing them, in my case, I am, so it did not matter. It did not take much force, just push gently until you feel it start to move."
I think one could pry the clutch stack up via the carrier side holes instead on the bearing.

"The thickess of this gear is what you can use to define the max clutch+steels stack before having preload, per design, there does not seem to be preload."
If no preload then one can spin one wheel with the other on the ground but this is not the case, and this means clutches are preloaded, and without using a spring washer. Keep in mind the pump movable piston is thicker than the center static part which is pressed on the 'spacer gear' to define the spider gears backlash.

Yes, but there is some lash, the top spider gear as shown on that photo is line to line on the planetary gears, so that gear and the spacer gear move along the center line of the carrier until the bottom out against the pump

Yes, but since I still had the ring gear, I was not going to pry against it and mar the teeth.

Interesting of why they used a spring washer between the pump and lock-ring; why not have the lock-ring directly pressing on the pump? The spring would allow the carrier bearings to float outward, in theory.

With the pump removed, did you verify that the lock-ring can be turned in passing the locking ball?

The pump housing (and its static center) is bottomed on the carrier step, this means the space between the 'spacer gear' and the side-gear (the two side-gears and the 4 spider gears are what you called 2 spiders and 4 planetary gears) defines the backlash.

There is no shim between the pump and the clutches stack? The pic below seems to show the arrowed plate is a shim or spacer as it has no teeth inner or outer. No?
