Existing mainshaft/drive-wheel/gearbox/output/body poses are retained. The tangency of two smooth wheel envelopes explains a perpendicular offset drive, not tooth contact, ratio, handedness or operation; teeth are intentionally absent. Factory six/22 counts are documentary comparisons, not fitted gear identification or a verified speedometer calibration. Carrier, O-ring, sleeve and seal are unloaded role comparisons without threads, tolerances, loaded seals, cable square, lubrication path or verified replacement/removal clearance. No complete speedometer cable route, service-interval counter configuration, right-angle adapter location or disassembly procedure is verified. Inspection separation is illustrative.",
