) Vebirl~s /i/fed with a mantra~ gearbox :
Lift one of the front wheels of the vehicle, and
engage’ 4th or 5th gear so as to rotate the crank-
shaft,
by means of the raised wheel.
1) Vehicles /itted with n torqee ronrwrter :
Two methods are permissible to rotate the crank
shaft :
- feed the starter “iota from (I &volt battery,
or remove the protective plate under the
converter casing, and rotate the converter
using a screwdriver.
1. Remove :
spore wheel,
cylinder head (carburettor engine 1,
the injection manifold and the rocker cover
(fuel injection engine 1.
2. Bring piston of cylinder No. 4 to TDC. with the
valves in (( rocking position x
NOTE : The TDC mark on engine flywheel co”
be see” at point (( a )) on the clutch housing.
3. Adjust clearance of inlet valve ( 1 ) of No. 1
cylinder to
1.10 mm (theoretical clearance 1.
4. Turn crankshaft exactly one turn in direction of
rotation of engine f m/i-clockwise iro>t! /lyre hpel

5. Check clearance of inlet valve on cylinder No. 1.
This must be between 0.05
and 0.25 mm.

((L-JETRONIC,,
The H L-Jetronic 1) system is’an intermittent low-pressure injection system which injects petrol into the inlet
manifold.
The system measures the quantity of air drawn in by the engine. which is the main parameter for calculating
the amount of fuel. to be injected. The metering of the fuel is carried out by electro-magnetically triggered
injectors. These are under constant fuel pressure. The quantity of fuel injected is proportional to the duration
of injection. which in turn is optimally determined for any given engin& operating condition by an electronic
control unit ( E.C.U. ) from information supplied by several electric sensors.
One of the principal contributions of the H L-Jetronic H system is the reduction in the level of pollution of the
exhaust emissions.
The (( L-Jetronic v system is made up of the following components :
1
: Electric fuel pump
2 : Fuel filter
3 : Thermal switch
4 :, Double relay
5 : Electronic control unit ( E.C.U. )
6 : Supplementary air control
7 : Pressure regulator
8 : Injectors
9 : Cold-start injector
10. Idling speed adjustment screw
11 : Air-flow sensor ( with incorporated air temperature sensor )
12 : Switch on throttle butterfly spindle
13 : Additional resistors for the injectors (8)

-AIR INLET SYSTEM’
Air drawn in via air filter ( 1 ) passes through the air-flow sensor (2’), via butterfly ( 3) and arrives in the inlet
distribution chamber, each pipe of which (4) leads to a cylinder.
-
‘I
Each cylinder has an electro-magnetic injector which is located very close to the inlet valve in order to improve
engine performance.
The supplementary air control (6) is located in parallel with the butterfly, and supplies the supplementary air
required by the engine to run smoothly when cold.
_ Once the engine has reached its normal running temperature, the idling speed air-flow is provided by a by-pass
valve
$ ( 5) which by-passes the butterfly as well.
.
2
co
T
$ It is important that the system be air-tight downstream from the air-flow sensor, so that no (( secondary )) air can
I
2 be drawn in, which would falsify the air-volume reading.
