BODY ALIGNMENT — Underbody

BF-54component photo

Underbody view is the most measurement-dense page in the K11 BF section. Each value is captured verbatim with its symmetric flag; mapping specific values to letter pairs would require higher scan resolution.

Continued from BF-53

Underbody

NOTE

Underbody alignment uses ~26 cross-measurements between top-down reference points (A–M upper-case on one side, a–m lower-case on the mirror side). Asterisks (*) indicate values that are symmetric on the opposite side. The side-elevation drawing on the right shows the Z-axis offset for each reference point. Refer to BF-53 for the corresponding measurement-point photos and hole diameters.
