Removal, installation and adjustment of front wall regulating shaft

Length of connecting rod (11) from accelerator pedal to guide lever

122

Length of pushrod (10) from longitudinal regulating shaft to accelerator pedal

1    Remove accelerator pedal (30—330).

2    Disconnect connecting rod.

3   Disconnect return spring, unscrew fastening nuts from bearing bracket and remove regulating shaft together with bearing bracket.

4 For installation proceed vice versa, while connect­ing return spring to inside hole. Grease bearing points as well as ball sockets of regulation with Molykote Longterm 2.

5 With engine stopped, step on accelerator pedal from inside vehicle up to stop on kickdown switch. Regulating lever on injection pump should rest against full load stop. Loosen adjusting screw (arrow), if required, adjust throttle linkage in such a manner that regulating lever rests against full throttle stop.

If the full load or idle speed stop is not attained with this adjustment, set pushrod (10) from longitudinal regulating shaft to accelerator pedal to 68 mm, measur­ed from center of ball socket to center of damping ring.

If the full load or idle speed stop is not attained with the above adjustment, set connecting rod (11) from guide lever engine compartment to accelerator pedal to 122 mm, measured from center of ball socket to center of ball socket. Adjust regulating lever inside vehicle, if required. For this purpose, loosen fastening screw (arrow), slightly release accelerator pedal and tighten fastening screw again.

1 Remove accelerator pedal (30—330).

2 Disconnect return spring and pushrod.

3 Unscrew plastic bearing inside vehicle and remove shaft by turning.

4 For installation proceed vice versa, while connect­ing return spring to inside hole.

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

5 With engine stopped, step on accelerator pedal from inside vehicle up to stop on kickdown switch. Regulating lever on injection pump should rest against full load stop. Loosen adjusting screw (arrow), if re­quired. Set throttle linkage in such a manner that regulating lever rests against full throttle stop.

1    Disconnect return spring (22) and force-off con­necting rod (5).

2    Remove accelerator pedal (30—330).

3 Unscrew fastening screws on bearing bracket, remove bearing bracket and accelerator pedal lever.

4 For installation proceed vice versa.

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