Adjustment of regulating linkage

A. Lefthand steering models 107, 116, 123, 126 Righthand steering models 107, 116, 126

1    Check regulating linkage for easy operation and bends. Replace linkage, if required.

2   Disconnect connecting rod (B) on throttle valve housing. Check whether throttle valve rests against idle speed stop. Reconnect connecting rod free of tension, adjust to specified length, if required.

Note: The connecting rod (B) should be made of round material with screwed-on ball sockets. Replace profilated sheet metal-connecting rod (A).

3   Adjust connecting rod (1,2) in such a manner that the rollers (3, 15) in slotted lever (4, 13) are resting free of tension against final stop.

To guarantee operation of microswitch (3) the slotted lever (13) is provided with a restoring spring (arrow). As a result, the slotted lever will return reliably against final stop.

Check whether Bowden wire for cruise control/ Tempomat rests free of tension against regulating lever (7). Adjust by means of adjusting nut (6), if required.

Check whether actuator rests against idle speed stop of cruise control/Tempomat. For this purpose, dis­connect pullrod (21) and push lever of actuator clockwise against idle speed stop.

When connecting pullrod (21) make sure that lever of actuator is lifted by approx. 1 mm from idle speed stop. Adjust pullrod, if required.

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

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

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

a) Adjust control pressure rod (11) with engine stopped. For this purpose, disconnect control pressure rod, push completely toward the rear against stop and reconnect free of tension. Adjust ball socket, if required.

b) Adjust Bowden wire (11) with engine stopped. For this purpose, disconnect connecting rod (22) and pull guide lever (23) in direction of arrow noticeably against idle speed stop on automatic transmission. Reconnect connecting rod (22) free of tension and adjust, if required.

1   Check regulating linkage and Bowden wire for easy operation, distortion and absence of kinks. Replace individual parts, if required.

2   Disconnect connecting rod (B) on throttly valve housing. Check whether throttle valve rests against idle speed stop. Reconnect connecting rod free of tension and adjust to specified length, if required.

Note: Connecting rod (B) should be made of round material with screwed on ball sockets. Replace profilated sheet metal-connecting rod (A).

3   Adjust connecting rod (2) in such a manner that roller (3) in slotted lever (4) rests free of tension against final stop.

The connecting rod can now be adjusted on one side only. Pay attention to installation position (refer to Fig.).

For installation date refer to section “A” Lefthand steering.

To guarantee operation of microswitch (3), the slotted lever (13) is provided with a restoring spring (arrow). As a result, the slotted lever will return re­liably to end stop.

Check whether Bowden wire for cruise control/ Tempomat rests free of tension against regulating lever (arrow). Adjust with adjusting nut (1), if required.

Check whether actuator rests against idle speed stop of cruise control/Tempomat. For this purpose, dis­connect pullrod (21) and push lever of actuator clockwise against idle speed stop.

When connecting pullrod (21), make sure that the lever of the actuator is lifted by approx. 1 mm from idle speed stop. Adjust pullrod, if required.

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

5 With engine stopped, step on accelerator pedal from inside vehicle up to full throttle stop or on 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.

a) Adjust control pressure rod (11) with engine stopped. For this purpose, disconnect control pressure rod, push completely toward the rear against stop and reconnect free of tension. Adjust ball socket, if required.
