The old school way to do it is to tighten the inner nut to 100 ft lbs, then back it off 1/3rd of a turn, then tighten the lock nut. This gets you pretty close, but when the target is a couple thousandths of an inch, im only comfortable by confirming that with a dial indicator on a magnetic base..
Anyone with a 145, 165, 185 needs to pay special attention to this advice. Getting the adjustment too tight is a great way to ruin the hub, bearings, and spindles. Ive replaced a few spindles for this reason.
