COOLING - EXHAUST - TANKExhaust Assembly
ATTENTION !
Descending pipe in operation, may reach high temperatures and consequently must not
co me in contact with flammable materials which may lead to their auto-ignition.
Catalytic converter is to be mechanical shock protected.
DISMOUNTIN G
In order to di smount the noise a bsorber assembly ( 1), lift t he ve hicle on an elevator and
perform the following operation s:
Loosen the nuts ( 2) of the attachment collar between the expansion chamber ( 3) and the
noise silencer ( 1).
Di smount the thre e a ttachment e lastic supports of the noise a bsorber, on the carri age
body, rear pa rt. Release the noise silencer.
In order to dismount the assembled expansion chamber (3), perform the following operations:
Di smount the c ollar ( 4) and disengage the e xpansion chamber assembled with the de -
scending pipe.
Dismount the three elastic supports of the assembled expansion chamber.
Loosen the attachment collar nuts ( 2) and remove the assembled expansion chamber by
easy rotation and onward pulling.
In order to dismount the descending pipe assembly (6), perform the following operations:
Dismount the engine shield.
Dismoun t the catalytic converter attachment nuts ( 7) on the two studs of the exhaust manifold
flange. Dismount the attachment screws of the converter support ( 5).
For EURO 96, dismount the oxygen sensor located in upstream of the catalytic converter.
For EURO 00, dismount the oxygen sensors located in upstream, consequently, in
downstream of the catalytic converter.
Dismount the collar (4) and disengage the assembled catalytic converter from the assembled
expansion chamber.
Remove the descending pipe.
REMOU NT I NG
Perform the dismounting operations in the reverse order.
Ensure a perfect sealing between the exhaust assembly elements, using sealing paste Wurth,
on the joining area length (inside) between the noise absorber – expansion chamber (0.013 Kg);
The oxygen sensor gasket is to be replaced at each dismounting.
The tightening moment between noise absorber and expansion chamber is: 3.6 daNm.
The tightening moment of descending pipe attachment nuts on the exhaust manifold flange is:
2 daNm. Tightening moment between the catalytic converter and expansion chamber: 2.5 daNm.
All elements are to be assembled having the ambient temperature.
