Removal and RKPP installation

The Manual Box of Gear Shifting (MBGS) can be removed without removal of the engine. The box is removed in case of need removals of coupling or replacement or repair of a box. It is not recommended to repair a box in house conditions.

For removal the car has to be lifted on necessary height. Besides, the corresponding garage elevator is necessary for lowering of a box.

 REMOVAL

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

As a result of shutdown of the 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 to 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 to the Section Removal and installation of a fan / casing of the fan.
4 Models 320d, 320i, 323i, 328i: Remove an aircombined box, address to 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 to the Section Removal and installation of the lower cover of a motive compartment.
6 Remove the amplifier of forward part of the car, address to 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 to 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). Thus 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 to 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 of-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 a 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.

20 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.

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

At removal and installation of a box do not allow that it hung on primary to a shaft as it can lead to damage of the conducted coupling disk. Extend a box back as far as it perhaps, turn approximately on a corner 10 ° counterclockwise and remove.


 INSTALLATION

22 Before installation check coupling, address to the Section Removal and coupling installation.
23 Check ease of the course of the bearing of switching off of coupling. Grease adjacent surfaces of the lever of switching off with ESSO UNIREX S2 greasing.

check greasing in grooves of shliyets of primary shaft. If greasing sticky, the conducted disk of coupling needs to be replaced. Address to the Section Removal and coupling installation.

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

25 Include the lever transfer.


 

Be convinced that both directing plugs-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 coupling disk, turn a hand a shaft behind for a driveshaft flange.

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

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

30 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.
31 Install the working cylinder of the drive of coupling, address to the Section Removal and installation of the working cylinder of coupling.
32 Raise a box a jack and fix a beam on the bottom and a box by the efforts specified in Specifications.
33 Clean a jack.
34 Fix the driveshaft 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 to Specifications).
35 Tighten bolts of fastening of the central bearing of the driveshaft the moment of 20 N • m.
36 Slightly tighten the moment 10 N • m a screw ring on a mobile element of the driveshaft.
37 Fix the heat-shielding screen on the bottom. Install system of release, address to the Section Removal and installation of system of release.
38 Fill RKPP with oil, address to the Section Check level/replacement of oil in a reducer of the back bridge.
39 Establish the amplifier of forward part, address to the Section Removal and installation of a beam of a forward suspension bracket.
40 Models 320i, 323i, 328i: Fix on a radiator the fan with the holder, address to the Section Removal and installation of a fan / casing of the fan.
41 Models 320d, 320i, 323i, 328i: Establish an aircombined box, address to the Section Removal and installation of a box of an air inlet.
42 Fix the lower cover of a motive compartment.
43 Models 316i, 318i: Fix on the holder of the coil of ignition.
44 Attach a negative cable (-) of the battery at the switched-off ignition. Establish hours.
