Ok, there is no torque spec for that #44 nut, you just tighten it good and tight so the inner bearing #43 is held with the axle shaft, not free to turn separately. Then lock it with the locking tab washer 45. It looks like it fits into the 46 tongued washer but I’m not sure about that.
The outer bearing race 43 fits into the housing 40, and when you have the right amount of shims 41 then the end float should be .005 to .008 inches, which you might just be able to feel. It should not be so tight that you can’t turn the axle, and not so loose that you feel a clunk if you push/pull the hub.
BTW Plate H1.2 is a little bit outdated, in that it shows the brake cylinder only used on early Mark V up to about Feb 1950.
