Cat 416C 4×4 front axle differential pinion bearing drag?

Hi. Does anybody know how many inch-pounds the pinion bearings must rotationally drag before the differential carrier is reinstalled? i.e. Tighten the pinion yoke nut, then put a torque wrench on an measure the rotational drag of the bearings? If not enough, tighten the pinion yoke nut a bit more, then measure again. My Dodge rear diff is about 20 in-lb to turn the pinion w/o the diff carrier installed. Not sure what the Cat 416C would be.
