 REMOVAL

Operation of lifting and car installation on supports is connected with danger! Therefore before carrying out operation familiarize with Poddomkrachivaniye's Section and towage

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

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

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

5 Models 320d: Unscrew bolts of fastening and remove a reception pipe from a turbokompressor flange.

6 Disconnect the exhaust silencer from the holder of RKPP, having unscrewed bolts of fastening-1-.

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

7 Models 316i, 318i: Rasstykuyte I will corrode - 3-sensors of oxygen-4-in a reception pipe.

The second sensor of oxygen is in a reception pipe behind the catalytic converter. Rasstykuyte I will corrode the second sensor of oxygen.

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

9 Unscrew fastening bolts traverses to the bottom (shooters on an illustration).

10 Disconnect both holders of the additional exhaust silencer to the bottom (shooters on an illustration).

11 Lower system of release and take out it.

The catalytic converter is sensitive to blows. Address with it carefully, do not allow blows and falling.


 INSTALLATION

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

Bolts, nuts of fastening and consolidation are surely 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 exhaust silencers are not replaced, sealing surfaces before assembly should be cleared a skin of the remains of products of combustion and laying.
3 Expose release system so that everywhere there was a gap at least in 25 mm in relation to the bottom. Besides, the trailer part of a pipe should have a uniform gap in relation to a contour of a back part of a body.

4 Establish to a traverse, tighten bolts of fastening the moment of 20 N • m.
5 Diesel engine: Fix a reception pipe to a turbokompressor the moment of 30 N • m. Previously check 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 evenly press nuts the moment of 30 N • m.

7 Unscrew bolts of-2-fastenings of the exhaust silencer to RKPP. Bolts tighten only after installation of all other elements of fastening to exclude deformations.

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