Tips for Shortening a Throttle Cable

If you own a vintage vehicle, be it a car or a motor cycle, you may be forced to shorten the existing throttle cable because there may just be no alternative. A broken cable may be shortened if all of the parts are present and the cable itself has not been frayed inside the outer covering.

Tip 1: Determine the Correct Length

Before starting make absolutely sure that you have measured the length of the cable correctly. Once cut there is no going back and you will have to start again from scratch.

Tip 2: Prepare the Components

Use about ¼ inch of copper tubing as the stopper on the end of the cable. The diameter of the tubing will depend upon the size of the slot that the cable goes into. Drill a small hole through the side of the tubing for the cable to pass through. Clean up the inside and outside of the tubing with fine sandpaper. Cut the cable to size. Feed the cable through ALL parts of the throttle assembly before attaching the stopper.

Tip 3: Fit the Stopper to the Cable

Feed the cable through the small hole in the side of the copper tube. Pull the cable back until all strands are inside the copper tube. Fill up the copper tube with solder. Use acid core solder to clean off any dirt or grease. File the copper tube flat on both sides of the cable. Fit the cable.
