no torque settings given, just snug, no play in bearings, some times the cotter key hole does not line up with the slot in the nut, I would rather have the bearing just a little tight rather than loose, a loose bearing can allow the rollers in the bearing to run a little side ways in the race and ruin both race and bearing
I believe the proper procedure for any front bearings is to bring it up snug and back off to the nearest cotter pin hole. There is never any play or danger of burning up a bearing.
