The 1975 Harley-Davidson Sportster uses a mechanical speedometer driven by a cable. Here's how to connect the speedometer cable on a 1975 Sportster:
1. Locate the Speedometer and Drive:
• The speedometer is mounted on the instrument cluster, usually on the left side of the handlebar.
• The speedometer drive, which is connected to the front wheel, is located on the front wheel hub.
2. Disconnect the Old Cable (if applicable):
•If you're replacing an existing speedometer cable, you'll need to disconnect the old cable first.
• Locate the cable connection point at the speedometer and drive, and use a wrench or pliers to loosen and remove it.
3. Prepare the New Cable:
• Uncoil the new speedometer cable and measure it against the distance from the speedometer to the speedometer drive. Ensure it's long enough with some extra slack.
•Apply a small amount of grease to the inner cable to reduce friction and ensure smooth operation.
4. Attach the Cable to the Speedometer:
• Insert the square end of the speedometer cable into the speedometer connection. Make sure it fits snugly.
• Secure the cable by tightening the nut or other fixing mechanism provided on the speedometer.
5. Attach the Cable to the Drive:
• Route the cable from the speedometer towards the front wheel.
• Connect the other end of the cable to the speedometer drive at the front wheel hub. Ensure it's properly seated and secure.
6. Secure the Cable:
• Use zip ties or other suitable fasteners to secure the speedometer cable along its route to prevent it from becoming entangled with other components.
7. Test the Connection:
•Rotate the front wheel to check if the speedometer cable moves smoothly and without any kinks or obstructions.
•Turn on the ignition and observe if the speedometer needle responds accurately as you rotate the wheel.
By following these steps, you can successfully connect the speedometer cable on your 1975 Harley-Davidson Sportster.
