Removal and AT installation

For removal the car has to be lifted on necessary height. Besides, the corresponding garage elevator is necessary for lowering of a box. The instructions given below belong to removal of RKPP. About differences at removal of AT it will be told in addition.

 REMOVAL

1 Disconnect a negative cable (-) of the rechargeable battery at the switched-off ignition. The battery is in a luggage compartment behind a cover on the right side. At the BMW 316i, 318i cars the battery settles down in a motive compartment.

As a result of shutdown of the rechargeable battery data from memory of malfunctions of some monitors are erased. If necessary before shutdown of the battery it is necessary to consider these memories of malfunctions. Address the Section Diagnostics of Malfunctions. Work it is desirable to carry out HUNDRED in conditions.

2 Models 316i, 318i: Turn off bolts of fastening and remove ignition coils from holders, having taken them aside that at removal of RKPP not to damage ignition cables.
3 Models 320i, 323i, 328i: Remove the fan with the holder from a radiator and displace a little upward, address the Section Removal and installation of a fan / casing of the fan.
4 Models 320d, 320i, 323i, 328i: Remove a vozdukhosborny box, address the Section Removal and installation of a box of an air inlet.

Rise and installation of the car on supports are dangerous! Therefore previously study Poddomkrachivaniye's Section and towage

5 Remove the lower cover of a motive compartment, address the Section Removal and installation of the lower cover of a motive compartment.
6 Remove the amplifier of a forward part of the car, address the Section Removal and installation of a beam of a forward suspension bracket.
7 Turn off bolts of fastening and remove a reception pipe from a final collector, address the Section Removal and installation of system of release.
8 Disconnect the thermofilter of system of release around RKPP from the car bottom.

9 Disconnect a flange of the cardan hinge from RKPP (an arrow on an illustration). Not to draw a flange, at an otvorachivaniye rotate only nuts, but not bolts.

10 Turn off bolts of fastening and remove the central bearing of the driveshaft (an arrow on an illustration). At the same time hold a shaft that it did not fall.

11 Remove the driveshaft from RKPP flange.

Tie a shaft a wire sideways to the bottom.

At removal of the working cylinder of the drive of coupling slowly unload a rod, otherwise through consolidation air will get. Suspend the cylinder with the attached hose on a wire to a body. If air gets to a hydraulic system, after installation air needs to be removed from system.

12 Remove the working cylinder, address the Section Removal and installation of the working cylinder of coupling.

13 Raise a few RKPP the garage elevator and prop up it.

14 Turn off bolts of fastening and disconnect a cross-piece at the bottom and RKPP.
15 Slowly lower RKPP the garage elevator so that the engine almost concerned a wall of a motive compartment.

Do not lower it too low not to damage.


16 Prop up the engine in front the second elevator that it after removal of RKPP could not overturn.

17 Remove lock brackets-4-on draft of switching from RKPP and the lever of switching. Remove washers-5 drafts of switching, remove draft.

At installation keep in mind that the big surface of washers-5-adjoins to draft of switching of a box.

18 Take away upward the screw-driver a clamp of a basic finger of draft of switching on a box. Take out a finger sideways.

19 Rasstykuyte the backing switch socket on a box. Release a cable of lamps of a backing and the sensor of oxygen from holders on a box.

Automatic transmission

20 Remove the fan with the holder from a radiator and pull a little up. Remove a vozdukhosborny box, address the Section Removal and installation of a box of an air inlet.
21 Remove a gear shifting selector cable on a box, address the Section Adjustment of Draft of the Selector.
22 I will corrode Rasstykuyte on a box for what turn a nut at the plug to the left.
23 Disconnect the holder at the case pallet for AT radiator oil pipelines.

24 Disconnect from a box the holder of an oil pipeline of a radiator (the shooter on an illustration), take out oil pipelines.

Substitute capacity for collecting the following oil. Do not allow hit of dirt in pipelines therefore close them plastic packages of elastic bands.

25 Uncover an opening-1-at a crankcase part of the block of cylinders. Turn out consistently 3 bolts of fastening of the converter of torque by means of a narrow head, for example, BMW 24 1 110 or any similar tool. You watch that bolts did not fall in a case. That bolts appeared in a groove, turn the engine for a hexagon of a pulley of a bent shaft.

26 Prop up a box the elevator from below of the car. It is possible to lean only around a box case, but not the pallet of a case.
27 Turn off 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 You watch that the converter did not slip out. For this purpose put a clip-1-at a box case the flat party to the converter and clamp. If the specified clip cannot be put, at removal of a box you watch that the converter did not slip out a box. Disconnect a box from the engine.

29 Turn out Torx screws of fastening of a flange of a box (an arrow on an illustration).

Screws have various sizes. Write down their arrangement.

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

At removal and installation of a box do not assume that it hung on primary to a shaft as it can lead to damage of the conducted clutch plate. Extend a box back as far as it is possible, turn approximately on a corner 10 ° counterclockwise and remove.


 INSTALLATION

31 Before installation check coupling, address the Section Removal and coupling installation.
32 Check ease of the course of the bearing of switching off of coupling. Grease the adjacent surfaces of the lever of switching off with ESSO UNIREX S2 lubricant.

check lubricant in grooves of shliyets of a main shaft. If lubricant sticky, the conducted clutch plate needs to be replaced, address the Section Removal and coupling installation.

33 Erase a rag lubricant from shliyets of a main shaft. Then apply a thin film of ESSO UNIREX S2 lubricant. You do not apply too much lubricant as it can get on frictional surfaces and lead to coupling operation refusals. The necessary amount of lubricant corresponds to the rice grain size.

34 Include the lever transfer.


35 Make sure that both guides of the plug-1-and-2-between the engine and a box stand still. Raise a box and enter it horizontally into coupling. If at installation the shaft of a box does not enter the conducted clutch plate, turn a hand a shaft behind for a driveshaft flange.

36 Screw bolts of fastening of a flange with washers. The moments of tightening are given in Specifications.
37 Grease a basic finger of draft of switching with KLUBER POLYLUB GLY 801 lubricant and insert. Lower a finger clamp down.

38 Put washers on a finger, observing the correct situation. The big surface of washers-5-adjoins to draft of switching. Install draft on the lever of gear shifting and the lever of a box and fix by lock brackets.

39 Join the socket of the switch of a backing and record it. Lay a cable of lamps of a backing and the sensor of oxygen in holders on a box.
40 Install the working cylinder of the drive of coupling, address the Section Removal and installation of the working cylinder of coupling.

Automatic transmission

41 Turn the torque converter on a box so that openings on levels showed to the center of openings on a flywheel. Screw BMW 24 2 300 adaptation in a level.

48 Install the selector and adjust it, address the Section Adjustment of Draft of the Selector.
49 Raise a box a jack and fix a beam on the bottom and a box by the efforts specified in Specifications.
50 Remove a jack.
51 Fix the driveshaft by the new self-stopped nuts to a box flange. The moment of an inhaling of threaded connections depends on a class of durability of bolts which is beaten out on a bolt head (address Specifications).
52 Tighten bolts of fastening of the central bearing of the driveshaft the moment of 20 N • m.
53 Slightly tighten the moment 10 N • m a screw ring on a mobile element of the driveshaft.
