Gurney -

It's Foot Pounds, not Foot per pounds, (Foot/pounds), and one foot pound is the torque from one pound applied ONE FOOT from the centerline of the bolt. Last I heard 1" isn't a foot (except maybe in the UK - I've had some experience with their "standards.")

(Dang those typos can be embarassing!)

Several methods have been used for "wheel bearings" but what my older overhaul manuals usually said was "make sure the bearing is clean and well-greased, torque to some low value while rotating the wheel to take the slack out, and then back off the nut until the cotter pin goes through the slot in the castle-nut - and cleanly through the hole in the axle."

Sometimes they added that if the pin goes in "at torque," the nut should be backed off the 1/6 turn to the next slot.

I don't recall the torque values recommended for seating, but recollection is that they were about what you'd put on a 1/4" bolt, or sometimes even a little less.

Some "shade tree mechanics" I've known said they just torqued the nut down "until there's drag when you turn the wheel," and then do the back off to the hole bit. They probably never saw a torque wrench (not based just on this particular procedure, but on general performance in other areas as well).
