yoke change 489 case w/o disassembling

you can also use a scale(think fish weighing scale with hook to hang fish) with a 1' bar bolted to yoke and scale on end of bar. You will also be able to "feel" crush sleeve if tightening by hand as it will be much more force to crush. I would tighten it until you feel sleeve and then a 1/16 turn more.
