is what you seek Ted. Looks like the dial indicator need to be set to 2mm. Slightly different check than what is called for on the 4.5 (which measures the amount of force required to turn the hub).
To paraphrase the manual:
Tighten the clamping nut, while rotating the hub, to the extent the hub will be hard to turn. Then slacken the clamping nut by approximately 1/3 of a turn, and release tension by whacking the spindle with a plastic mallet.
Personally, I have never used any sort of gauge to set wheel bearings, other than the gauge of what I feel while rotating the hub. I must have been doing something right, because I've never lost a wheel bearing.
