 REMOVAL

Operation of lifting and car installation on supports is connected with danger! Therefore before operation carrying out familiarise with Razdelom Poddomkrachivanie and towage

1 Lift and establish the car on supports. Remove the bottom cover of an impellent compartment, address to Section Removal and installation of the bottom cover of an impellent compartment.
2 Spray all болтовые connections of system of release by means for rust dissolution. Wait some time, the rust will not be dissolved yet.

3 Models 316i, 318i: Turn away bolts of fastening and remove a reception pipe from a flange of a final collector-1.

4 Models 320i, 323i, 328i: Turn away bolts of fastening and remove a reception pipe from a flange of a final collector (an arrow on an illustration).

5 Models 320d: Turn away bolts of fastening and remove a reception pipe from a flange турбокомпрессора.

6 Disconnect the muffler from holder РКПП, having turned away bolts of fastening-1.

Bolts-2 at installation of system of release turn away to expose system without перетяжек.

7 Models 316i, 318i: Расстыкуйте a socket-3 gauges of oxygen-4 in a reception pipe.

The second gauge of oxygen is in a reception pipe behind каталитического the converter. Расстыкуйте a socket of the second gauge of oxygen.

8 Bring under release system the garage lift with a wooden lining. The system weight makes about 30 kg.

9 Turn away bolts of fastening traverses to the bottom (arrows on an illustration).

10 Disconnect both holders of the additional muffler to the bottom (arrows on an illustration).

11 Lower system of release and take out it.

The Katalitichesky converter is sensitive to blows. Address with it cautiously, do not suppose blows and falling.


 INSTALLATION

At installation of elements of system of release watch to crumpling pipes. Otherwise at the analysis of the fulfilled gases incorrect results can be received.

Bolts, fastening and consolidation nuts are necessarily replaced with the new. Rubber holders also it is necessary to replace on new if they have a time or deformations.

1 It is recommended to grease a carving of bolts of fastening with high-temperature copper greasing, for example, Liqui Moly LM-508-ASC. It will facilitate dismantling at repair.
2 If mufflers are not replaced, sealing surfaces before assemblage should be cleared a skin of the rests of products of combustion and linings.
3 Expose release system so that everywhere there was a backlash at least in 25 mm in relation to the bottom. Besides, the trailer part of a pipe should have a uniform backlash in relation to a contour of a back part of a body.

4 Establish to a traverse, tighten bolts of fastening by the moment 20 Н•м.
5 Diesel engine: Fix a reception pipe to турбокомпрессору the moment 30 Н•м. Preliminary check up a sealing ring, if necessary replace it. A ring grease with high-temperature greasing.
6 Petrol engine: Establish a reception pipe on a final collector with new consolidation and in regular intervals press nuts the moment 30 Н•м.

7 Turn away bolts-2 fastenings of the muffler to РКПП. Bolts tighten only after installation of all other elements of fastening to exclude deformations.

8 Tighten all bolts and fastening nuts the efforts resulted in Specifications.
9 Models 316i, 318i: Join штекерные connections of gauges of oxygen and lay a cable.
10 Check up tightness of system of release, address to corresponding section.
11 Establish the bottom cover of an impellent compartment, address to Section Removal and installation of the bottom cover of an impellent compartment.
