Detroit Chassis Engine Serial Number Label - VIN F0A04742 Spec Plate

This image shows a data/spec plate (adhesive label) affixed to a dirty cast-metal component, uploaded to the gallery of a 2015 Ford F-550. The label carries a QR code at the top and three lines of printed text. It reads "Detroit Chassis," followed by a shortened VIN reference "VIN: F0A04742," and an "Engine S/N" line showing the serial number "E172A031114307004" (some digits are difficult to confirm due to dirt and glare). The label appears to be a manufacturing traceability tag applied by Detroit Chassis, associating the component or engine with a specific vehicle VIN sequence and engine serial number. No year, model, engine displacement, fuse data, torque specifications, or wiring information appears on the label. A reader can learn the engine serial number and the partial VIN association for the unit photographed, which can be useful for ordering parts, verifying provenance of a used engine or chassis component, or matching a drivetrain to its original vehicle. The heavy dust coating and low-contrast printing limit full certainty of every character, particularly in the long serial number string.
