Note Gr. 3.314252 in the application listing for a base plate assembly. My guess is that the related, un-numbered, parts shown in exploded view of Plate 34C - that is, the shaft, worm and sector gears, thrust spring, adjusting screw, jam nut, cover and screws, and inspection plate and screws - were only serviced (at least by Packard) as part of that assembly.

WRT to lockwasher for the jam nut, I've not inspected this on my cars, but, generally, a jam nut is tightened against another nut/screw without any lockwasher. At least, that's the way it is on the aging Saginaw steering gears that I've adjusted for sloppy steering.

Is this jam nut elliptical or "peened" to also act as a lock nut?
