Ford Rear Axle Identification Tag Diagram - S825C / 10.50 Ring Gear (A0027436)

This document is a Ford service-manual style illustration (figure number A0027436) showing how to locate and read the axle identification tag on a rear axle assembly. The upper portion of the drawing depicts the rear axle housing and differential carrier with the round differential cover flange, and an arrow indicates that the identification tag is attached at the differential cover. The lower portion is an enlarged view of the tag itself, with seven numbered callouts pointing to the individual data fields stamped on the tag. The example tag reads "S825C" on the top line (callout 1) and "3L55 10.50 1 F 21" on the bottom line (callouts 2 through 7). From this diagram a reader can learn where the axle tag is mounted and how the tag's data is segmented: the top-line code, the axle model/ratio code (3L55, indicating the visible characters), the ring gear size figure (10.50), and additional single-character and two-digit codes (1, F, 21). The document itself does not include a legend explaining what each callout number means, nor does it state a vehicle year, model, or engine applicability.
