FITTING THE AFTER SALES SLEEVE
95478R1
Once a collar has been used once, renew it.
The nut on the collar has a groove (A) to ensure it
is tightened to the correct torque. When the nut is
tightened and the groove disappears, it causes a
distinct clicking sound and the nut is then tighte-
ned to the correct torque (2.5 daN.m).
NOTE : there are two different diameters of
sleeve available:
-∅ 50 mm,
-∅ 45 mm .
IMPORTANT:
- check that there is no point of contact bet-
ween the exhaust pipe and the vehicle body,
- check for the presence and correct positioning
of all heat shields for the exhaust pipe,
- check that the two cutting marks are correctly
aligned.
99227S
To avoid any leaks in the exhaust pipe, the sleeve
must be correctly positioned over the two exhaust
pipe sections. The pipe must be against the stops
inside the sleeve.
Begin by positioning the sleeve over the used sec-
tion of the pipe, adjust the collar by tightening
gently.
Check the position of the pipe in relation to the
stops.
Fit the new section of the pipe.
Before fitting the sleeve on the pipe, apply a little
mastic to the inner ring on the sleeve to prevent
leaks.
(Exhaust mastic, Part Number. 77 01 421 161
SODICAM).
IMPORTANT : the bolt and nut used for tighte-
ning the sleeve must be aligned vertically to
avoid any risks of touching the underside of the
body.

SPECIAL TOOLING REQUIRED
IMPORTANT :
During all operations on the fuel tank or on the
fuel supply circuit , it is vital :
- to refrain from smoking and handling incan-
descent objects in the vicinity of the working
area,
- to avoid fuel projections, due to the residual
pressure present in the pipes during removal .
REMOVAL
To remove the pump-sender unit assembly, it is
not necessary to remove the tank, as it is accessi-
ble through the inside of the vehicle. To do this :
- disconnect the battery,
- lift the rear bench seat ,
- remove the steel access cover,
- remove the electrical connection at (1),
- remove the clips at (2).
