wheel.
2. Check oil level if necessary.
4. Preparing pressure checking apparatus
Connect pressure gauge 2279-T ( ,wdun/r~l

Tiqhten union screw ( 3 )
6. Start engine With oil temperature at 100’ C pressure should
be :
a+ 2000 rpm 3 bars mini43.5 psi ) o+ 4000 rpm 4 to 5 bars (58 to 72.5psi)
7. Rrmave union 6004-T and pressure qouqe. Tightening torque : 30 to 35 m \ ( 3 to 3.5 m.kg)
( 21 l/2 to 25 l/2 ft.lb )

NOTE This operation con also be carried out
with the aid of CI MULLER kit,reference 451.

4. Checking the main accumulator : a) Disconnect HP inlet pipe ( 1) from safety
valve.
b) Plug HP inlet pipe fusing p[u~s D
and E ). : c ) Tighten pressure regulator bleed screw.
Disconnect contact breaker lead from coil.
Operate storter,watching the pressure g”“ge :
the pressure should rise steadily and then
appear to stobilize.
Note this reading, which is the inflation
pressure of acc”mulator.
This preksure must equal 62 ‘, To
bars
(899 IE,psi) Corned lead of contact breaker
5. Checking cut-out :
a) Checking cut-out ~TPSSU~~~ : Start engine.
With pressure regulator bleed screw tightened,
examine the pressure gauge.
When pressure stops rising, reading indicates
maximum cut-out pressure.
This pressure m”st be equal to
170 t’5 bars
(2466 ?,73 p:i ). When the c”t-o”t pressure is obtained allow
the engine to nrn for a few minutes in order
to stabilize pressure.
Stop engine.
Examine the pressure gauge and note the fall
in pressure for the next 3
minutes. If the fall in’pressure exceeds
10 bark 4 145psi) check seai of plug D and repeat, the test sequence.
If the result of test is the some, the pressure
regulator is defective,
Replace it 01 repair it.
When cutout takes place, slightly slacken
pressure regulator bleed screw.
The pressure should fall gently then rise (IS~.
soon (IS the HP pump begins to operate.
The minimum reading indicated on tbe pressure
gauge corresponds to the cut-in pressure.
This pressure must be 145 +,5 bars
(2103 ?,73
psi ). If these cut-in and cot-out pressures do
not lie within the given tolerances, check the
pressure regulator.
c) Slacken the pressure regulator bleed screw.
d) Remove plug D and connect HP inlet pipe ( 1)
to safety valve.

Watch pressure gauge and note the pressure
drop in the next 3
minutes. If pressure drop
exceeds 10 bors*( 145 psi ) repeat the test.
If the re< is the same. the broke control
valve is defective : change it.

The crossmember supporting the steering has slots at its fixing point on the front subframe.
Any vertical movement of this crossmember alters the steering geometry.
WARNING
This operation is only to
be carried out in certain ccxses such as
-accidental impact, with repercussions on the steering system.
-work on the vehicle entoiling removal of steering crossmember.
- vehicle with poor
road stability ( p oar stright-line stability) 01 with excessive tyre weor.

As a precaution. a steering wheel iocking
tool may also be
used. 2. Mark position of vehicle in relation to
ground :
Secure a weighted length of string to the front
bumper. and
mark the position of the weiqht on
the ground ( The
object of this is to always bring
the vehicle

carry out correct measurements 1.
NOTE Other procedure

it is possible to use the free projector.
Secure projector to scuttle panel crossmemher, and
focus it onto a fixed object, which will indicate the
initial positioning of the vehicle.
3. Measure the variation in the wheel alignment wheel

normal driving position ).
- the 6th and the 10th graduation (compressor
