PRECAUTIONS
SPECIAL FEATURES
CAUTION:
 The engine must not operate with:
- Diesel engine fuel containing more than 10% diester,
- Petrol, even in tiny quantities.
 The system can inject the diesel into the engine at a pressure up to 1400 bars. Before carrying out
any work, check that the injector rail is not under pressure and that the fuel temperature is not too
high.
 You must respect the cleaning and safety advice specified in this document for any work on the high
pressure injection system.
 Removal of the interior of the pump and injectors is prohibited. Only the flow actuator, the fuel tem-
perature sensor and the venturi can be replaced.
 For safety reasons, it is strictly forbidden to slacken a injection tube union when the engine is run-
ning.
 It is not possible to remove the pressure sensor from the fuel rail because this may cause circuit
contamination malfunctions. If the pressure sensor fails, the pressure sensor, the rail and the five
injection tubes must be replaced.
 It is strictly forbidden to remove any high pressure supply pump pulley marked number 070 575. If
the pump is being replaced, the pulley must be replaced.
 It is forbidden to repair the wiring connecting the knock sensor (accelerometer) and the CKP sensor
(engine speed sensor). If the wiring should fail, it has to be replaced with new wiring.
 Applying 12 volts directly to any component in the system is prohibited.
 Ultrasonic carbon removal and cleaning are prohibited.
 Never start the engine without the battery being connected correctly.
 It is essential to replace all the disconnected air inlet plastic pipes.
INSTRUCTIONS FOR INJECTION TUBES
CAUTION:
All the injection tube removed must be systematically replaced along with the clips.
TIGHTENING THE INJECTION TUBES
NOTE:
fit the pump/rail pipe before the rail/injector pipes.
Rail-pump pipe

 Grease the threads of the injection tube nuts,
 Insert the injection tube olive into the taper of the high pressure pump outlet,
 Insert the injection tube olive into the taper of the high pressure rail inlet.
 Move the nut into position by hand, on the rail side then the pump side,
 Tighten the rail,
 Tighten the injection tube nuts on the rail side then on the pump side.
Rail/injector pipes
 Undo the rail,
 Grease the threads of the injection tube nuts,
 Insert the injection tube olive into the taper of the high pressure injector inlet,
 Insert the injection tube olive into the taper of the high pressure rail outlet,
 Move the nuts into position by hand, on the injector side then the rail side,
 Tighten the rail,
 Ensure that the new clip, supplied with the new injection tube, is fitted,
 Tighten the nuts of the injection tubes on the injector side first and then on the fuel rail side.
NOTE:
Before fitting a new injection tube, move back the nuts on the pipe then lightly lubricate the nut
threads with the oil from the sachet provided in the parts kit.
CHECKING SEALING AFTER REPAIR
CAUTION:
After any operation, check that there are no diesel leaks.
 Reprime the circuit using the priming pump.
 Start the engine and allow to warm up at idle speed, visually inspecting for any fuel leaks.
 Apply tracing fluid around the high pressure connections of the pipe that has been replaced.
 Once the engine coolant temperature is above 50°C and provided there are no malfunctions present, carry
out a road test, taking the engine speed up to 4000 rpm at least once to check that there are no leaks.
 Perform a visual inspection after the road test to make sure that there are no high pressure leaks.
 Clean off the tracing fluid.

INSPECTION
WARNING:
Be sure to perform when the engine is stopped.
1. Inspect drive belt for cracks, fraying, wear and oil. Replace drive belt if necessary.
2. Manually evaluate the drive belt tension (tension cannot be measured using frequency meter).
3. Replace drive belt when tension is beyond normal operating limit.
CAUTION:
Auto-tensioner must be replaced with a new one when the belt is replaced.
ADJUSTMENT
Belt tensioning is not necessary, as it is automatically adjusted by auto-tensioner.

release drive belt tension.
INSTALLATION
1. Install the drive belt.
CAUTION:
 Make sure drive belt is correctly engaged with the pulley
groove.
 Check for oil and coolant on drive belt and each pulley
groove.
 Certain drive belts have five teeth whereas the air condi-
tioning compressor pulley, power-assisted steering pump
pulley, and generator pulley all have six teeth.In this case,
it is essential to check that inner tooth (O) of the pulleys
remains free when fitting the drive belt.
Never turn the engine in the opposite direction to its nor-
mal operating direction.
Use a brush to remove any deposits from the crankshaft
pulley V grooves.
2. Release drive belt auto-tensioner, and apply tension to drive belt.
3. Turn crankshaft pulley clockwise several times to equalize tension between each pulley.

Inspection and AdjustmentINFOID:0000000001381465
INSPECTION
1. Place the valves of the cylinder concerned at the “end of
exhaust - beginning of intake” position and inspect the clearance
(X).
NOTE:
Dimension (Y) corresponds to the tappet thickness sizes (there
are 25 sizes available).
2. Compare the values recorded with the values specified, then
replace the tappets which are not within tolerance.
ADJUSTMENT
1. The camshaft must be removed to replace the tappets after
determining dimension (Y).
2. Set up the following assembly using dial gauge stand
[KV113B0050 (Mot. 252-01) (commercial service tool) or equiva-
lent tool] and dial gauge, then calibrate the gauge.
3. Raise the gauge extension (without modifying the position of the
magnetic support/gauge assembly), then slide in the tappet to
be measured.
Note dimension (Y) and repeat the operation for the tappets
where the valve clearance is not within tolerance.
Select the various thicknesses of the tappet(s). 25 sizes of sin-
gle-piece tappets are available. Refer to EM-333, "
Camshaft". Clearance when the
engine is cold: Refer to EM-333, "

COMPRESSION PRESSURE
InspectionINFOID:0000000001381466
1. Warm up engine thoroughly. Then stop.
2. Remove glow plug.
3. Disconnect high-pressure supply pump harness connector to avoid fuel injection during measurement.
4. Connect compression gauge attachment hose [SST:
KV113B0400 (Mot. 1592)] (A) to the hole for glow plug.
5. Connect compression gauge (B) to attachment hose (A).
6. Turn ignition switch to START for cranking and check compres-
sion gauge.
7. Perform the same procedure for the other cylinders.
 If compression pressure is below minimum value, check valve
clearances and parts associated with combustion chamber (valve, valve seat, piston, piston ring, cylin-
der bore, cylinder head, cylinder head gasket). After checking, measure compression pressure again.
 If any cylinder has low compression pressure, pour a small amount of engine oil into the glow plug hole
of the cylinder to re-check it for compression.
- If the added engine oil improves the compression, piston rings may be worn out or damaged. Check pis-
ton rings and replace if necessary.
- If the compression pressure remains at low level despite the addition of engine oil, valves may be mal-
functioning. Check valves for damage. Replace valve or valve seat accordingly.
 If two adjacent cylinders have respectively low compression pressure and their compression remains
low even after the addition of engine oil, cylinder head gaskets are leaking. In this case, replace cylinder
head gaskets.
8. Disconnect compression gauge (B) and attachment hose (A).
9. After inspection is completed, install removed parts.
10. Start the engine, and make sure that the engine runs smoothly.
11. Perform trouble diagnosis. If DTC appears, erase it. Refer to EC-1043, "
BASIC INSPECTION : Descrip-
tion". Compres-
sion pres-
sure: Refer to EM-333,
"GeneralSpecification".
