CHECKING THE FUEL SUPPLY PRESSURE
SPECIAL TOOLING REQUIRED
Mot. 1311-01 Fuel pressure test kit (with 0 ;+ 10 bars
pressure gauge included)
Mot. 1311-04 T piece (J union)
Mot. 1311-06 Tool for removing fuel pipes
Disconnect:
- the oil vapour rebreathing pipes and the fuel
vapour recirculation pipes,
99372S
- the fuel supply pipe using small section tool
Mot. 1311-06 (method described in section 13
"Fuel gallery").
99375R
Connect the T piece Mot. 1311-04 to the gallery,
then reconnect the fuel supply pipe to the T piece.

CHECKING THE OIL PRESSURE
SPECIAL TOOLING REQUIRED
Mot. 453-01 Hose clamp pliers
Dir. 1204 Pressure test union
Dir. 803 Metric thread union
Fre. 1085
or Pressure gauge
Fre. 244-03
Fre. 284-06 Connecting pipe
Fit clamp Mot. 453-01 to the low pressure pump
hose.
Disconnect the high pressure pipe (take
precautions to catch the oil which will run out).
Insert union Dir. 803 (metric thread) between the
pipe and the pump.
For engines where it is fitted, remove the
pressostat on the rigid pipe (high pressure).
Connect the pressure test union
Dir. 1204 and the oil pressure gauge
Fre. 1085 (or Fre. 244-03 + Fre. 284-06).
77840R1
Connect pressure gauge Fre. 1085 (or Fre. 244-03
+ Fre. 284-06).
Remove clamp Mot. 453-01.
Top up the pump level and run the engine to
check the pressure.
Wheels in straight line:
Regardless of engine speed, the pressure should
not exceed 5 to 7 bars.
Full lock to one side:
Hold the steering at full lock, the maximum
pressure should be 79 to 86 bars.
This operation should not be prolonged to avoid a
high increase in the oil temperature.
Remove union Dir. 803 and pressure gauge
Fre. 1085 or Fre. 244-03 , cutting the supply to the
pump with clamp Mot. 453-01.
Reconnect the high pressure pipe and remove
clamp Mot. 453-01.
Top up the oil in the reservoir.
