[QUOTE="ionbeam, post: 189743, member: 277"] The bottom castellated nut sets the compression load for both the upper and lower bearings. The second castellated nut is a ‘jam nut’ that locks the bottom nut in place, then in a belts & suspenders mode a two prong locking sleeve drops down over both nuts. The top steering head nut gets torqued to 85 lb/ft to hold the top triple tree bracket to the steering stem. The triple tree gets sandwiched between the castellated nuts and the top steering head nut. The 85 lb/ft is only pressing on the top castellated nut.
