The term you are looking for is "up and touching." No play cold.

Torquing the spindle means to stretch the spindle that "sets" the bearings moving members up to minimum play as they are tapered. It seats the biggest and smallest as it rotates to keep an average fit up.

You want "fit up" to be your "running fit." Not tighten down to a point that's it's tighten up.

You want or need to allow for rolling clearances as things warm up but not be loose, just up and touching so the members roll and not wander out of their intended path under loading.

I use torque values 25 foot pounds to seat them and 15 to 25 inch pounds after backing off the two slots and pull it back up to slot that aligns to the cotter pin hole with this "inch" variable pound reading.

If you do not have a inch pound wrench you can use one to two foot pounds maximum. You can set a clicker to the lowest setting of even a zero. There is a tolerance given on each pound reading that if if it clicks you are really close. Adjust to how it feels to you.

Bottom line...
You should not have play but a held in place and free rolling wheel when done.
Hand fitting is your final indicator....experience!

By the way, this was an old post you found but done well with lots of information.
