 REMOVAL

Lifting operation and installations of the car on supports is connected with danger! Therefore before carrying out operation study Poddomkrachivaniye's Section and towage

1 Lift and install the car on supports. Remove the lower cover of a motive compartment, address the Section Removal and installation of the lower cover of a motive compartment.
2 Spray all bolt connections of system of release by means for dissolution of a rust. Wait some time, the rust will not be dissolved yet.

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

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

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

6 Disconnect the muffler from the holder of RKPP, having turned off bolts of fastening-1-.

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

7 Models 316i, 318i: Rasstykuyte the sensor socket-3 of oxygen-4-in a reception pipe.

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

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

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

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

11 Lower system of release and take out it.

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


 INSTALLATION

At installation of elements of system of release you 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 new. Rubber holders it is also 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 lubricant, for example, of Liqui Moly LM-508-ASC. It will facilitate dismantling at repair.
2 If mufflers are not replaced, sealing surfaces before assembly should be cleared a skin of the remains of products of combustion and laying.
3 Expose system of release so that everywhere there was a gap at least in 25 mm in relation to the bottom. Besides, a trailer part of a pipe has to have a uniform gap in relation to a contour of a back part of a body.

4 Establish to a traverse, tighten fastening bolts the moment of 20 N • m.
5 Diesel engine: Fix a reception pipe to a turbocompressor by the moment of 30 N • m. Previously check a sealing ring, if necessary replace it. Grease a ring with high-temperature lubricant.
6 Petrol engine: Establish a reception pipe on a final collector with new consolidation and evenly press nuts the moment 30 N • m.

7 Turn off bolts-2 fastenings of the muffler to RKPP. Tighten bolts 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 appropriate section.
11 Establish the lower cover of a motive compartment, address the Section Removal and installation of the lower cover of a motive compartment.
