JEGS 555-62087 Speedometer Driven Gear Features:

• Purpose and Function: Speedometer driven gears are essential components that transfer rotational motion from the vehicle’s transmission to the speedometer cable, which in turn drives the speedometer needle to display vehicle speed.
• Gear Ratio Matching: These gears must be carefully matched to the vehicle’s tire size and axle ratio to ensure accurate speedometer readings. Mismatched gears can result in incorrect speed readings and odometer errors.
• Location and Accessibility: The driven gear is usually located at the end of the speedometer cable or Vehicle Speed Sensor (VSS), where it engages with the transmission’s drive gear.
• Installation and Calibration: When installing a new driven gear, it’s important to verify compatibility with the transmission drive gear. Some vehicles may require recalibration or the use of a gear calculator to determine the correct driven gear for precise speedometer function.
