Since the usual type of a tachometre which works from impulses of system of ignition, cannot will be applied on diesel engines, on them the diagnostic socket for connection of the special measuring equipment not accessible in house conditions is established. In case idling turns differ from demanded, it is necessary to use a special tachometre or to address on station Peugeot.

Adjustment of a cable of an accelerator

PERFORMANCE ORDER

1. Before adjustment warm up the engine to normal working temperature that the radiator fan has joined at least two times. 2. Check up adjustment of a cable of an accelerator as follows. 3. The lever on the fuel pump should contact with the screw of adjustment of the maximum turns (it is specified by an arrow), otherwise remove an adjusting clip of a cable of an accelerator and establish it in a demanded flute for maintenance of a normal tension of a cable of an accelerator. 4. Remove a cable of an accelerator and check up that the control lever is in contact to the screw of a dosage of fuel.

Adjustment of turns of idling

PERFORMANCE ORDER

1. Ослабьте a counternut also unscrew the screw of a dosage of fuel while it will not depart from a control lever. 2. Ослабьте a counternut also turn the screw of adjustment of turns of idling before installation of demanded number of turns of the engine. Tighten a counternut.

Adjustment of a dosage of fuel

PERFORMANCE ORDER

1. Insert a lining or an edge щупа in the thickness of 1 mm between a control lever of the pump and the screw of adjustment of a dosage of fuel. 2. Start the engine in an idling mode. Engine turns should correspond to demanded values. 3. If necessary ослабьте a counternut also establish the screw of adjustment of a dosage of fuel demanded turns of the engine. Repeatedly tighten a counternut. 4. Remove a lining or an edge щупа and check up idling turns.

Adjustment of the accelerated idling

PERFORMANCE ORDER

1. Switch off the engine and check up that the lever is in contact to the adjustment screw. If it is necessary, ослабьте a counternut and move a nut () a cable of a regulator of increase in turns of idling. Tighten a counternut (). 2. Remove a vacuum hose from a diaphragm of management of increase in turns of idling and start the engine. Check up, that the engine worked on the raised turns of idling. If necessary ослабьте a counternut also move a nut of a cable of a regulator of increase in turns of idling. Tighten a counternut. Switch off the engine and repeatedly connect a vacuum hose to a diaphragm. 3. In end disconnect a tachometre. 4. If adjustments on increase in turns of idling are executed, adjust the shock-absorber.

Shock-absorber adjustment

Elements of adjustment of the fuel pump of high pressure Bosch

1. A counternut 2. A lining 3. A core

4. The adjusting screw 5. A control lever the pump

PERFORMANCE ORDER

1. Execute all adjustments described above. 2. Ослабьте a counternut also unscrew the screw of adjustment of the shock-absorber of the control lever, located on a back part of the lever, and insert a lining or an edge щупа in the thickness of 1,0 mm between a core of the shock-absorber and the adjusting screw (fig. Elements of adjustment of the fuel pump of high pressure Bosch see). 3. Rotating the adjusting screw, establish such backlash that the edge щупа could move easily between a core of the shock-absorber and the screw. Tighten a counternut.
