How do you do that? The spec is the drag while turning at a specific speed. The pictures show a special hand tool, so perhaps the speed isn't critical. Do you use a "clicker" torque wrench so that you don't need to read a needle or dial while turning?
(I still think my idea of putting torque wrench on the end of a power screwdriver could be an inexpensive yet accurate way of doing this.)
Which part do you measure? You have to do the same torque-drag setup on the output bearings, changing the shims slightly each time to get the right preload. Then once you have the total shim thickness, you have to install the ring gear (hot from the oven) and balance it from side to side to get the right contact pattern on the ring gear. That seems to require at least few shims to select from.
Or do you measure the old center section of the diff, compare it to the size of the replacement, and just use the measurement?
I'm not trying to be argumentative here. In the past "never touch the insides of a diff, just spend $100 to buy a good used one" was reasonable advice. I expect that a bunch of e30 people will be looking at OBX torsens and there will be lots of questions about how to correctly set up the diff so that they don't burn up or howl.
