The slop in simple non precision threaded rods ( of any brand) and washer/pressure disk tools is vast. Unless the pressure disk is held so well by the shaft that NO chance of cocking is possible then the bearing alignment is determined by the frame seats (be they machined or c clips).
Sorry guys but this is real. Take a Park press tool and see how much play there is between the shaft and the pressure disk. make your own judgments. The few that I have used are not very tight.
One way to insure the frame's situation determines the bearing seating (and not the press) is to tap the outer race of the bearing with a drift punch without also contacting the inner race. Working around the circumference of the outer race with the punch will insure the bearing seat is fully settled into it's intended location.
Now whether this end location is correct is another issue. But that's for the frame builder/manufacturer to insure. Andy.
