Do not lower it too low not to damage.

16 Prop up the engine in front the second lift that it after removal Manual transmission could not overturn.

17 Remove lock скобы-4 on draught of switching from outside Manual transmission and the switching lever. Remove washers-5 draughts of switching, remove draught. At installation keep in mind that the big surface of washers-5 adjoins to draught of switching of a box.

18 Take away upward a screw-driver a clamp of a basic finger of draught of switching on a box. A finger take out sideways.

19 Rasstykujte a socket of the switch of a backing on a box. Release a cable of lanterns of a backing and the gauge of oxygen from holders on a box.

Automatic transmission

20 Remove the fan with the holder from a radiator and pull upwards a little. Remove air collector a box, address to Section Removal and installation of a box of an air inlet.
21 Remove a cable of the selector of a gear change on a box, address to Section Adjustment of draught of the selector.
22 Rasstykujte a socket on a box for what turn a nut at the tip to the left.
23 Disconnect the holder at the pallet crankcase for маслопроводов radiator АТ.

24 Disconnect from a box the holder маслопровода a radiator (the marksman on an illustration), take out маслопроводы. Substitute capacity for gathering of following oil. Do not suppose dirt hit in pipelines, therefore close their plastic packages with elastic bands.

25 Uncover apertures-1 at картерной parts of the block of cylinders. Turn out consistently 3 bolts of fastening of the converter of a twisting moment by means of a narrow head, for example, BMW 24 1 110 or any similar tool. Watch that bolts have not fallen in картер. That bolts have appeared in a groove, turn the engine for hexahedron a pulley of a cranked shaft.

26 Prop up a box the lift from below the car. It is possible to lean only in area crankcase boxes, instead of the pallet crankcase.
27 Turn away bolts of fastening of a box to the engine. The arrangement of bolts of a flange corresponds to an arrangement of bolts of fastening of a box.

28 Watch that the converter has not slipped out. For this purpose put a clip-1 at crankcase boxes the flat party to the converter and clamp. If it is impossible to put the specified clip, at box removal watch that the converter has not slipped out a box. Disconnect a box from the engine.

29 Turn out screws Torx of fastening of a flange of a box (an arrow on an illustration). Screws have the various sizes. Write down their arrangement.

Remove back a box from directing plugs and a primary shaft and take out it by means of the assistant.

At removal and installation of a box do not suppose, that it has hung on primary to a shaft as it can lead to damage of a conducted disk of coupling. Extend a box back how much it probably, turn approximately on a corner 10 ° counter-clockwise and remove.

31 Before installation check up coupling, address to Section Removal and coupling installation.
32 Check up ease of a course of the bearing of deenergizing of coupling. Grease adjoining surfaces of the lever of deenergizing with greasing “ESSO UNIREX S2”.

Check up greasing in grooves шлицев a primary shaft. If greasing sticky, it is necessary to replace a conducted disk of coupling, address to Section Removal and coupling installation.

33 Erase a rag greasing with шлицев a primary shaft. Then apply a thin film greasings “ESSO UNIREX S2”. Do not put too much greasing as it can get on frictional surfaces and lead to refusals of operation of coupling. The necessary quantity of greasing corresponds to the size of grain of fig.

34 Include the lever transfer.

35 Be convinced that both directing plugs-1 and-2 between the engine and a box are at a stop. Raise a box and enter it horizontally into coupling. If at installation the box shaft does not enter into a conducted disk of coupling, turn a hand a shaft behind for a flange карданного a shaft.

36 Screw bolts of fastening of a flange with washers. The tightening moments are resulted in Specifications.
37 Grease a basic finger of draught of switching with greasing “KLUBER POLYLUB GLY 801” and insert. Lower downwards a finger clamp.

38 Put washers on a finger, observing correct position. The big surface of washers-5 adjoins to draught of switching. Establish draught on the lever of a gear change and the lever of a box and fix lock bracket.

39 Join a socket of the switch of a backing and fix it. Lay a cable of lanterns of a backing and the oxygen gauge in holders on a box.
40 Establish the working cylinder of a drive of coupling, address to Section Removal and installation of the working cylinder of coupling.

Automatic transmission

41 Turn the twisting moment converter on a box so that apertures on laths showed to the centre of apertures on a flywheel. Screw adaptation BMW 24 2 300 in a lath.

42 At interface of the engine and a box three laths of fastening on the converter should coincide with three ledges on an engine flywheel. The subsequent change of position is impossible and can lead to damages.

43 Put an automatic box and cautiously insert the adaptation 24 2 300 into an aperture on a conducted disk. After box fastening take out the adaptation forward from a lath (the marksman on an illustration).

44 Remove a clip with crankcase boxes and screw three bolts of fastening of the converter of the moment in box apertures. Tighten bolts the moment 45 Nm. Apply only original bolts.

45 Remove a protective film and connect маслопроводы to a box, having fixed in the holder. Replace sealing linings.
