I have seen several service station parts from Lionel with one wheel pressed on the axle with the bearing already installed on the axle. The bearing is pressed into the truck frame by pressing on the wheel. This method requires that the bearing be pressed into the truck frame at the same time as the worm wheel is being pressed onto the center of the axle. Sounds like it takes lots of hands. The bearing on the opposite side would already have been pressed into the truck frame. Then the final wheel is pressed on after the worm wheel has been centered. The advantage of doing it this way is the serrated portion of the axle does not have to be pressed through the bearing bore, which scores it and may move it out of the proper location.
