1   Slightly grease knob bolt (a) with Molykote-Longterm 2.

2   Insert bearing bushing with collar (36) in pushrod (5) and press pushrod on knob bolt (a). Pay attention to correct seat of bearing bushing.

1   Push regulating rod with damping ring from lever of regulating shaft.

2   Remove accelerator pedal (30—330).

3   Remove heater box (83-100).

4   Disconnect restoring spring and unscrew fastening screws from plastic bearings.

5   Push out plastic bearings in upward direction and remove regulating shaft with bearing.

For installation proceed vice versa, while attaching restoring spring to inner hole.

Grease bearing points as well as ball sockets of regulation with Molykote-Longterm 2.

On vehicles with automatic transmission 722.3 (W 4 A 040) disconnect Bowden wire (11) and reconnect after adjusting full throttle stop.

6 With engine stopped, step on accelerator pedal from inside vehicle up to full throttle stop or with automatic transmission up to stop on kickdown switch. Throttle valve lever should rest against full throttle stop. If required, adjust regulating linkage with adjusting screw (arrow) in such a manner that the throttle valve lever rests against full throttle stop.

If the full throttle or idle speed stop is not attained with this adjustment, setpushrod from longitudinal regulating shaft to accelerator pedal to 105 mm length, measured from center of ball socket to center of damping ring (refer to Fig. item 1).

5 With engine stopped, step on accelerator from inside vehicle up to full throttle stop or with automatic transmission up to stop on kickdown switch. Throttle valve lever should rest against full throttle stop. If required, adjust regulating linkage with adjusting screw (arrow) in such a manner that the throttle valve lever rests against full throttle stop.

If the full throttle or idle speed stop is not attained with this adjustment, adjust pushrod (5) from longi­tudinal regulating shaft to accelerator pedal to 68 mm in length, measured from center of ball socket to center of damping ring. 30.2 llb-320/4 F2

If the full throttle or idle speed stop is not attained with this adjustment, adjust connecting rod from guide lever engine compartment to accelerator pedal to 122 mm, measured from center of ball socket to center of ball socket. If required, adjust regulating lever inside vehicle. For this purpose, loosen fastening screw (arrow), pull accelerator pedal slightly in up­ward direction and tighten fastening screw again.

5 With engine stopped, step on accelerator pedal from inside vehicle up to full throttle stop or with automatic transmission up to stop on kickdown switch. Throttle valve lever should rest against full throttle stop. If required, adjust regulating linkage with adjusting screw (arrow) in such a manner that the throttle valve lever rests against full throttle stop.

If the full throttle or idle stop is not attained with this adjustment, adjust pushrod (5) from longitudinal regulating shaft to accelerator pedal to 220 mm in length measured from center of ball socket to center of damping ring.

6 With engine stopped, step on accelerator pedal from inside vehicle up to full throttle stop or with automatic transmission up to stop on kickdown switch. Throttle valve lever should rest against full throttle stop. If required, adjust regulating linkage with adjusting screw (arrow) in such a manner that the throttle valve lever rests against full throttle stop.

If the full throttle or idle speed stop is not attained with the previous adjustment, adjust connecting rod (21) from guide lever engine compartment to accelerator pedal and connecting rod (40) to specified length, measured from center of ball socket to center of ball socket.
