Caution: Do not remove the sealing ring from the inner bulkhead of the engine compartment.
5. Remove the accelerator cable through the bulkhead into the engine compartment.
Installation
1. The accelerator cable is installed in the reverse order of removal. If necessary, check and adjust the accelerator cable operation.
Adjustment
1. Check that the throttle rod and cable move smoothly and without sticking. Lubricate the throttle rod if necessary.
2. In the initial position of the accelerator pedal, there should be a gap of 0.5-1.0 mm between the spring at the end of the accelerator cable and the plastic mounting block in the throttle guide lever. Otherwise, turn the adjusting knob to set the required gap.
3. When replacing the accelerator cable, it is usually not necessary to adjust the throttle rods. If necessary, the throttle rods must be adjusted at a service station, as this is a very complex operation.
