Starter Drive Gear & Flywheel Engagement Diagram - Engaged vs Disengaged

This is a simple hand-drawn schematic illustrating how a starter motor's drive gear (pinion) interacts with the engine flywheel in two states. The left diagram, labeled 'Starter disengaged,' shows the gear position when the starter is at rest — the small drive gear sits retracted, not meshed with the toothed flywheel ring. The right diagram, labeled 'Starter engaged,' shows that the 'gear should extend to engage as starter turns,' with the pinion moved outward along the starter shaft to mesh with the flywheel teeth. Orange arrows in callout boxes point to the pinion gear position in each state. The document contains no part numbers, torque specifications, wire colors, or vehicle-specific applicability information; it is a generic conceptual diagram useful for understanding or diagnosing starter drive engagement — for example, verifying that the starter drive gear extends properly to mesh with the flywheel during cranking. It was uploaded to a 1990 Ford Bronco gallery, but nothing in the drawing itself ties it to a specific year, make, or model.
