CHECKING THE FUEL PRESSURE
SPECIAL TOOLING REQUIRED
Mot. 1311-01 Fuel pressure test kit (with a pressure
gauge 0; + 10 bar tool kit)
Mot. 1311-05 Junction tool (for union K)

IMPORTANT : during the opening of the fuel cir-
cuit , be sure to use a cloth to avoid possible pro-
jections of fuel due to the residual pressure.
Disconnect the fuel supply pipe using the tool
Mot. 1311-06 with the largest section (see method
described in section 13 "Injector gallery").

DIESEL EQUIPMENT
Pump - Timing

IMPORTANT : the engine must only be rotated by
turning a wheel, in 5th gear, and in its operating
direction; if it is accidentally turned in the
opposite direction, repeat the operations for
checking and adjusting the timing.
CHECKING THE SETTING OF INJECTION PUMPS
FITTED WITH RAM PULLEYS
Turn the engine twice in the operating direction
(moving one wheel and having engaged 5th
gear).
Remove the timing shaft plug situated on the
pump cover.
Fit tool Mot. 1079 and zero the dial gauge on
pump cam "rest" zone (this operation will be
made easier by turning the engine in its operating
direction).
NOTE : in order to obtain a precise adjustment,
and to avoid bringing the dial gauge to its limit, it
is advisable to adjust it to 1 mm.

Lock the engine using tool Mot. 1054, according
to the following procedure :
- Turn the engine in its operating direction (clo-
ckwise from timing end).
- Locate the spot on the camshaft pulley where
the reference mark will appear .
- Stop the engine from turning half a tooth be-
fore the two reference marks align.

- Fit the pin, tool Mot. 1054.

- Keep a constant pressure on the pin.
- Turn the engine slowly until the pin
penetrates into the slot in the crankshaft .
- Check the pump piston lift, which may be read
on the dial gauge.
- The value is marked on the load
potentiometer lever.
- If the value is incorrect, adjust the timing (see
following method).

- Using tool Mot. 1358, set the timing,
turning the tool anticlockwise until the timing
value is obtained.
- The value is marked on the load lever.
NOTE : if the timing value is exceeded during
adjustment, bring the engine back by one
revolution , to recuperate the play using tool
Mot. 1358 , then repeat the previous timing
phase.
Leave pin Mot. 1054 in place.
Slightly pretighten bolt (1) using tool Mot. 1359,
to a torque not exceeding 2 daN.m (left hand
thread).
IMPORTANT : the torque wrench used for this
operation must operate to the left .
Remove the pin Mot. 1054.
Fit tool Mot. 1377 or 1200 to immobilise the
pulley.
Turn the engine by hand anticlockwise to bring
the locking tool into contact with the pulley.
Tighten bolt (1) to a torque of 9 daN.m, using
tool Mot. 1359.
Turn the engine over twice and check the pump
timing once again.
Lock the engine using tool Mot. 1054, according
to the following procedure :
- Turn the engine in its operating direction (clo-
ckwise from timing end).
- Locate the spot on the camshaft pulley where
the reference mark will appear .
- Stop the engine from turning half a tooth
before the two reference marks align.

Adjusting idle speed
13
12870R
It is vital to make these adjustments when the en-
gine is warm, and after the engine cooling fan
has operated at least twice.
The idle speed adjustment and anti-stalling
function adjustment must be carried out
correctly, since these operations directly
influence the behaviour of the engine at idle
speed and in the deceleration phase (hesitation
idle speed lasts too long, etc.).
1 Idle speed adjustment screw
2 Load lever
3 Residual flow adjustment screw (anti-stalling
function)
4 Fast idle lever
5 Idle speed cable grip
FAST IDLE SPEED
Without applying a vacuum to the LDA, position
the cable grip (5) at 2 ± 1 mm from the fast idle
speed lever (4).
NOTE : the fast idle speed value is not directly ad-
justable; it is adjusted on the injection unit.
CHECKING THE MAXIMUM SPEED
Whilst the engine is warm, accelerate to full load ;
the engine speed must be between 4 500 and
4 700 rpm (this adjustment can only be carried
out in a Renault Injection Centre workshop).
IDLE SPEED AND RESIDUAL FLOW ADJUSTMENT
(anti-stalling)
a)Ensure that the fast idle speed function is not
operational .
b)Adjust the idle speed to 825 ± 25 rpm. using
screw (1).
c)Place a 4 mm shim between the load lever (2)
and the residual flow screw (3).
d)Adjust the engine speed to 1 250 ± 50 rpm.
using the residual flow screw (3).
e)Remove the 4 mm shim then accelerate
sharply twice.
f)Check the conformity of the idle speed; if
necessary, repeat the idle speed adjustment
and check the residual flow once more.

CHECKING CANISTER BLEED OPERATION
Incorrect operation of the system may cause the
idle speed to be unstable or the engine to stall.
Check the conformity of the circuit (see
operational diagrams)
Be sure to check that the pipe marked "CAN" on
the solenoid valve is correctly connected to the
canister.
Check the condition of the pipes to the fuel tank.

2Canister bleed solenoid valve
3Canister
4Fuel tankAt idle speed connect a pressure gauge
(- 3 ; +3 bars) (Mot. 1311-01) to the "CAN" outlet
on the solenoid valve, to check there is no vacuum
(the command value read by the
XR25 for #23 re-
mains minimal X = 0.7 % ). Is there a vacuum ?
YESIgnition off, use a vacuum pump to apply a
vacuum of 500 mbars to the solenoid valve
at (C). This should not vary by more than 10
mbars in 30 seconds.
Does the pressure vary?
YESThe solenoid valve is faulty. Renew it. Air
must be blown into the pipe (A) connecting
the solenoid valve to the canister to remove
any particles of active carbon.
NOThere is an electrical fault. Check the circuit.
NOUnder bleeding conditions (not at idle
speed, engine warm), the vacuum should
increase (the value for #23 on the XR25
should also be seen to increase).
