Ford Supercharger Bolt Tightening Sequence Diagram (Fig. N0049439)

This document is a single service-procedure illustration (figure number N0049439) depicting a supercharger assembly mounted atop an engine intake area. The diagram uses ten circled numbered callouts (1 through 10) pointing to bolt locations around the perimeter of the supercharger housing, arranged with callouts 7, 3, 1, 5, and 9 along the top edge and 8, 4, 2, 6, and 10 along the bottom edge. This numbering pattern, alternating from the center outward, is characteristic of a fastener tightening (torque) sequence used when installing the supercharger onto the engine. The image contains no accompanying text, torque specifications, part numbers, or captions—only the numbered callouts and the figure reference number. A reader can learn the correct order in which to tighten (or loosen, in reverse) the supercharger mounting bolts: starting with the center bolts (1, 2), then working outward alternately (3, 4, 5, 6) and finishing with the outermost bolts (7, 8, 9, 10). The scan was uploaded to a 2007 Ford Mustang gallery, suggesting it applies to a supercharged Mustang engine (e.g., Shelby GT500 5.4L), though the document itself does not state a year, model, or engine.
