REFITTING - Special points
Pre-position the gearbox control cables.
Position the engine/gearbox assembly in its
compartment. Check the rear of the gearbox in relation
to the sub-frame.
Fitting suspended mountings: see section 19
"Suspended mountings".
Tighten all the bolts, nuts and studs to the
recommended torques.
Refitting is the reverse of removal.
Press the brake pedal several times to bring the
pistons into contact with the brake pads.
Reprogram all the components deprogrammed by
disconnecting the battery.
Fill the refrigerant circuit using the filling station (see
section 62 "Air conditioning").
Refrigerant fluid R134a: 800 ± 20 g.
Carry out:
–filling and bleeding of the cooling circuit (see
section 19),
–filling and bleeding of the power assisted steering
circuit,–bleed the hydraulic clutch circuit.
Damage to the union leads to replacement of the
master cylinder, and thus removal/refitting of the
gearbox.IT IS ESSENTIAL THAT YOU FOLLOW THE
BLEEDING METHOD GIVEN BELOW
VERY IMPORTANT:
When bleeding use a 19 mm ring spanner to
immobilise the rotating union (C) while tightening
and loosening the bleed screw (A) so as not to
damage the slave cylinder and the union.

Accessories belt
REMOVAL
Put the vehicle on a two post lift.
Disconnect the battery.
Remove:
–the front right wheel,
–the front right wheel arch,
–the lower engine cover.
Using a ring spanner, turn the tensioner axle clockwise to release the belt and
insert a tool (e.g.: Allen key) to lock the tensioner in this position.
REFITTING
Replace the accessories belt.
NOTE: never refit a belt once it has been removed, but replace it.

Tighten:
–the tension wheel bolt (8),
–the camshaft timing sprocket bolts (9) to a torque of
1 daN.m.
Remove the camshaft timing tools Mot. 1534 and
Mot. 1537 and the TDC pin Mot. 1536.
Rotate the crankshaft through two revolutions in a
clockwise direction (timing side).
Pin the crankshaft to top dead centre (the top dead
centre mark on the crankshaft accessories pulley must
be in the vertical axis of the engine).
Fit the camshaft timing tools Mot. 1534 and
Mot. 1537.
Check that the tab of Mot. 1537 moves vertically
without constraint.
Undo the camshaft timing sprocket bolts by a
maximum of one turn. Checking the timing and the tension
Undo the tension wheel bolt (8) while holding the
eccentric with a 6 mm Allen key.
Pivot the tension wheel eccentric clockwise, until the
surface (10) of the tab (11) is aligned with the
upper surface (12) of tool 1537.

–the camshaft timing sprocket bolts (9) to a torque of
1 daN.m.Remove the camshaft timing tools Mot. 1534 and
Mot. 1537 and the TDC pin Mot. 1536.
Refit the cap in the TDC pin opening applying
RHODORSEAL 5661 to the thread and by tightening
to a torque of 2.2 daN.m.
Refitting is the reverse of removal.
To refit the right-hand suspended mounting, you must
consult section 19 "Suspended mountings".

THE TURBOCHARGING PRESSURE ON THE
TURBOCHARGER FITTED ON THE G9T 710
ENGINE IS NOT ADJUSTABLE.
In operation, the pressure should stabilise at
210 ± 3.5 mbar.
REMOVAL
Removal or refitting of the turbocharger requires the
removal of the engine and transmission assembly.TIGHTENING TORQUES (in daN.m)

IMPORTANT: Never attempt to remove the
turbocharger with the engine in place; you will not be
able to follow the recommendations for refitting the oil
supply pipe (1) and the constraints created by blind
tightening the connection (3) will lead to the pipe (1)
rupturing in service.
Fit:
–the pipe (1) to the turbocharger by tightening the
union (3) by hand,
–the turbocharger, by holding the union (4) and
tightening it manually. Tighten the turbocharger
mountings on the manifold to a torque of 2.7 daN.m.
Tighten the unions (4), then (3).
IMPORTANT: It is essential to change the special seal
at the turbocharger oil inlet union (3).
Before running the engine, disconnect the pressure
rail sensor connector (5).
Then run the starter motor until the oil pressure
warning light goes out (persist for a few seconds).
Reconnect the sensor, preheat and start the engine.Run the engine at idling speed and check that there
are no leaks at the oil connections.
Using the fault finding tool, erase the fault as a result
of the sensor being disconnected.
Special precautions
●Ensure that no foreign bodies enter the turbine or
compressor during the refitting operation.
●If there has been a fault in the turbocharger, check
that the air-air exchanger is not full of oil.
If the air-air exchanger is full of oil, it must be
removed, flushed with a cleaning agent and then
left to drain properly.
●Check that the turbocharger oil return pipe is not
partially or completely blocked by scale. Check
also that it is perfectly tight. If not, replace it.
