Adjusting the throttle cable (30)
1. When the engine is stopped and the accelerator pedal is not pressed, there should be a gap of 0.5 to 1.0 mm between the guide spring (30/7) and the guide element (30/5), otherwise set it using the adjusting screw (30/3).
2. The crank arm (32/5) must be in contact with the idle speed limiter of the throttle valve, otherwise replace the connecting rod (32/4). The connecting rod must be installed very precisely. The microswitch in the idle position must be pressed (closed).
3. The roller (32/8) must fit against the end stop of the adjusting lever (32/7) without tension. If not, adjust the connecting rod (32/4) accordingly.
4. Adjust the Bowden cable to set the control pressure (98) by turning the adjusting screw (98/2) until the tip of the rocker arm (32/2) is at the same height as the tip of the rocker arm (32/6).
5. With the engine stopped, have a partner press the accelerator pedal until the throttle lever stops, and secure the latter in the maximum fuel supply position. In the case of an automatic transmission, do not operate the accelerator pedal switch (S16/7).
6. Check whether the throttle shaft lever fits against the throttle lever stop. Automatic transmission: If not, turn the adjusting screw (30/3) accordingly. Manual transmission: Adjust the throttle lever stop.
Adjusting the Throttle Lever Stop in the Footwell (only in case of manual transmission)
(Original source of information: www.MercedesMan.ru)
1. Disengage the throttle lever stop in the footwell by rotating it to the left and pull the lock bolt out slightly.
2. Slowly depress the accelerator pedal to the full fuel position until the throttle lever rests on its stop.
3. In this position, fix the throttle lever stop (38) by rotating it to the right in the inner space.
4. Release the accelerator pedal (24). There should be a gap of 0.5 to 1.0 mm between the driver spring (30/7) and the guide element (30/5), otherwise, adjust the adjustment using the adjusting nut (30/2) inside the vehicle.
5. Lubricate the Bowden cable between the tip and the guide element with anti-corrosion grease (30/5).
6. If available, check the temperature control adjustment.
Adjusting the tempomat
1. Unhook the connecting rod (32/11) on one side of the ball head.
2. The adjustment lever (32/7) must be in neutral position.
3. Turn the adjusting shaft (32/13) of the speed control actuator (M16) clockwise (in the direction of the arrow). In this case, the executive body is in a neutral position.
4. Turn the adjusting shaft (32/13) of the speed control actuator (M16) clockwise (in the direction of the arrow). In this case, the executive body is in a neutral position.
5. Then reattach the connecting rod. In this case, the actuator lever should be raised approximately 1 mm from the throttle lever stop.
6. Otherwise, adjust the connecting rod. Press the spherical insert. Loosen the lock nut and screw in or out the spherical insert, tighten the lock nut again.
