big truck wheel bearings

1964 Intl. Loadstar 1800. What is the correct procedure for tightening the front and rear wheel bearings? I can only assume that they are not supposed to run preloaded. Is this correct? On smaller vehicles you can kinda feel the play just a little but this big truck has some heavy hubs. Any tips?

that for reference, this is what I do. Put the wheel and tire back on the hub. Now tighten the wheel bearing up all the way to tight. (the wheel will not spin very easy.) Now back the wheel bearing nut off just a bit ( 1/4 turn or less) . Now spin the wheel again, if the bearing is set right .... the wheel will spin back wards just a tiny bit when it stops. Place something on the floor right next to the wheel to use as a spotter point.If the wheel stops without a slight back spin it is likely to tight. Back the nut off just a tweek and try again. When you can spin the wheel and it will stop and then move back wards ( only moves about 1/16 inch or less ) the bearing is set correctly. To check your work , place a pry bar on a block on the floor with one end under the tire. Try to pry the tire up. The hub should have almost *no* movement. I said *almost*. :o) If you place your hand on the hub while doing this you will feel a slight pop. that is the hub moving. There is a couple notes here. #1 the bearings are of course *new* right? #2 Do not do this with *used* wheel bearings. For used wheel bearings. ........ Good luck. I will not go there. I sure hope I am posting this right. I am a newbie at this. HTH Dave

old rule of thumb if they are tapered roller bearings is bring them up snug and back them off two flats of the nut and cotter pin em there. this allows for heat exspansion....
