- the suspended engine mounting housing (1),
- the injection pump pulley housing (2).

Pin the engine using tool Mot. 1054. For this
operation, turn the engine so that the index of
the camshaft sprocket is in line with the marking
on the timing cover (use a mirror).

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.
DI1303-1
- 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).

Fit tool Mot. 1358 into the three openings of
flange (B).
Turn the tool - flange assembly so that the three
pins of the tool fit into the three slots in the ad-
justing ring bolt.

Turn the tool-flange assembly clockwise until tool
Mot. 1358 locks, thus allowing the pulley to be
placed at the start of timing position .
Remove the immobilising tool Mot. 1317 or
Mot. 1200.
Turn the engine twice in its operating direction
(moving one wheel and having engaged 5th
gear).
Fit tool Mot. 1079 and zero the dial gauge on
the pump cam "rest" zone (this operation will be
made easier by turning the engine in its operating
direction).

- Keep a constant pressure on the pin.
- Turn the engine slowly until the pin
penetrates in the slot in the crankshaft.
- 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.

This test can only be carried out using a lead testing kit supplied by NAUDER.
To obtain a testing kit, contact your local After Sales Head Office.
Part numbers : - Complete kit : T900
- 40 test papers : T900/1
ANTIPOLLUTION
Test for the presence of lead
14
METHOD
a - Test conditions :
- Engine stationary.
- Exhaust pipes warm.
- Do not test when the temperature is below 0°C.
b- If necessary use a soft cloth to clean the inside of the exhaust pipe so any soot deposits are removed.
c- Wearing the gloves, take a test paper and moisten it slightly with distilled water (the paper is not
effective if it is too wet).
d- Press the damp paper onto the cleaned exhaust pipe immediately and hold it there firmly for about a
minute.
e- Remove the test paper and allow to dry. The test paper will turn red or pink if lead is present.
IMPORTANT: The test for lead should only be carried out on the exhaust pipe, never on the oxygen
sensor.
