  2. Load two pairs: spacer, F695 flange down, F695 flange up, spacer, spacer, F695 flange down, F695 flange up, spacer.

Eight items, two spacers meeting in the middle, no flange face-to-face anywhere. Same 20 mm stack as the A drive.

What you're looking at

Manual p.78: the four-bearing post, drawn on the left on the B frame because it mirrors the A frame. It is still the post farther from the motor bore; the page position changed, the rule did not.

Caution
