I'm with wrench bender. You will be able to feel if they are to tight or two loose. Tighten to seat, back off tighten until you feel it to bind a little then back off to where the cotter pin will fit. Make sure they are well lubricated but that there is not any lube on the compression surfaces of the bearing or washer. I always recheck them after a few hundred miles and the grease has had a chance to heat up and disperse.
