[2] H M8 screw: ().0188.E Tool kit C.0188
[3]Injection pump setting peg Ø 6 mm : ().0188.H
After carrying out the necessary dismantling operations on the vehicle, proceed in the following manner:
Remove:
The screws
(6), (7), (9), (10)and (12).
The upper casing (8).
The intermediate casing (11).
WARNING:Refit the screw (6)equipped with a washer.(Thickness 5 mm)
Turn the front RH wheel to turn the engine.(Normal direction of rotation) Bring the camshaft and injection pump pulleys to their setting point.
Position the flywheel peg, using tool [1].(From below the vehicle) Turn the engine until the peg [1]engages in the flywheel.

CHECKING AND SETTING THE DELPHI MECHANICAL INJECTION PUMP
Engine: WJY (continued)
Peg:
The camshaft hub, using tool [2].
The injection pump hub, using tool [3].
Impossible to peg the camshaft.Reset the valve timing (See page 245).
Possible to peg the camshaft, but not the injection pump.Carry out the following operations:
Loosen the screws of the injection pump hub.
Turn the injection pump hub.
Insert the peg
[3]into the setting hole.
Tighten the screws of the injection pump hub.Tighten to 2,3 ±0,2 m.daN.
ESSENTIAL:If setting the diesel injection pump proves impossible, reset the valve
timing.(See page 251)
Remove:
The tools [1], [2]and [3].

ADJUSTING THE MECHANICAL CONTROLS OF THE DELPHI INJECTION PUMP
Engine: WJY
Adjusting the fast idle.
Engine cold.
Ensure that the lever (2)is up against its stop to the right.
If not, adjust the tension of the cable (3)using the cable clamp (1).
Finish tensioning using the sleeve tensioner (4).
Engine hot. Check that the cable (3)is in tension.
Checking the thermostatic sensor. There should be a minimum 6 mmcable travel between a cold and a hot engine.
Adjusting the accelerator control.
Prior conditions.
Engine hot (cooling fan is engaged twice).
Checking the accelerator cable tension. Fully depress the accelerator pedal.
Check that the lever (6)is against its stop (5)otherwise, alter the position of the pin.
If not, adjust the position of the accelerator cable tensioning retaining pin.
Ensure that in the idle position the lever
(6)is against the stop (7).

ADJUSTING THE MECHANICAL CONTROLS OF THE DELPHI INJECTION PUMP
Engine: WJY (continued)
Adjusting the antistall (residual output).
Insert a 3 mmthick shim (10)between the throttle lever (6)and the antistall screw (7).
Push the stop lever (8).
Insert a 3 mmdiameter peg (9)in the lever (2).
Adjust the engine speed to 1500 rpm ± 100using the stop screw (7).
Remove the shim (10)and the peg (9).
Adjusting the idle speed.
Adjust the speed using the idle adjustment screw (11).
Idling speed:825 ± 25 rpm.
Checking the engine deceleration.
Move the throttle lever (6)to obtain an engine speed of 3000 rpm.
Release the throttle lever (6).
The deceleration should be between 2.5and 3.5seconds.
The drop should be approximately 50 rpmin relation to the idle speed.
Deceleration too fast, (the engine has a tendency to stall)slacken the screw (7)by a quarter turn.
Deceleration too slow, (engine speed is greater than the idle speed)tighten screw (7)by a quarter turn.
NOTE:In each case, check the idle speed for any necessary adjustments.
