1978 Ford Bronco V8 Distributor Diagram - Cap, Vacuum Advance, Hold-Down Bolt

This document is a line-art illustration of a V8 distributor assembly installed on an engine, with callout labels identifying its main external components. The drawing shows the distributor cap with eight spark plug wire towers plus a center coil tower, and labels point to the TERMINAL (a cap tower), CAP CLIP, CAP, ADAPTER, ADAPTER CLIP, DISTRIBUTOR BODY, VACUUM ADVANCE DIAPHRAGM (the round canister with vacuum nipple on the side of the distributor), and the HOLD-DOWN BOLT that secures the distributor base to the engine block. A directional arrow near the hold-down bolt appears in the lower left of the illustration. The document contains no part numbers, torque specifications, year/model applicability statements, or text beyond the component labels. A reader can learn how to identify the external parts of this style of distributor — useful when removing or replacing the cap (released via cap clips), locating the vacuum advance diaphragm for testing or replacement, and finding the hold-down bolt that must be loosened to rotate or remove the distributor for ignition timing adjustments. The eight cap towers indicate the diagram applies to a V8 engine. It was uploaded to a 1978 Ford Bronco gallery as an exploded parts reference.
