How to Install Dual Throttle Cables?
2 Answers
Adjust the clearance and tightness of the throttle handle, then test acceleration. This indicates interference in the throttle cable, which causes a rustling sound when pulled, mostly due to the cable being coiled around the handle. During operation, a "clicking" sound may occur, in which case it is best to replace with a new cable. Hold the adjustment nut and pull the cable outward by 2-3mm, then check if the clearance is appropriate. Turn the adjustment nut clockwise to tighten the cable. When the clearance returns to its pre-failure state, the cable tension is considered appropriate.
I've installed dual throttle cables a few times, and the operation is quite straightforward. First, ensure your vehicle has a mechanical throttle system, and prepare tools such as a set of wrenches and screwdrivers. Then, disconnect the negative terminal of the battery to avoid any short-circuit risks. Next, remove the original single throttle cable: loosen the fixing bolts on the throttle pedal and then detach the connection point on the throttle body. When installing the new dual throttle cables, connect one side to the pedal and the other to the throttle body; make sure each cable is adjusted to the proper tension—too tight will affect throttle response, while too loose may cause shaking. Finally, reconnect the battery, start the engine to test if the throttle opens and closes smoothly, ensure there's no sticking when pressing the throttle at idle, and then gradually test-drive to check. Choose durable cables to avoid frequent replacements, and regularly inspect for wear after modification to extend service life. The whole process takes about half an hour and is suitable for DIY beginners to try.
