 REMOVAL

1 Remove a casing of the air filter, address to Section Removal and installation of the air filter of the engine.
2 Remove spark plugs, address to Spark plug Section.

3 Disconnect a ventilation branch pipe картера at a cover of a head of cylinders of the pipeline ”.

4 Turn away bolts of fastening and uncover heads of cylinders (an arrow on an illustration). Thus pay attention to rubber linings of bolts of fastening later correctly to establish them.

5 Remove the fan fan/muftu, address to Section Removal and installation of the fan with вязкостной муфтой.
6 Uncover a camshaft of inlet valves.

7 Disconnect маслопровод (an arrow on an illustration) at double block VANOS.

8 Instead of маслопровода attach to double block VANOS the compressed air through a corresponding adapter and submit air pressure from 2 to 8 bar.

These and subsequent operations are necessary to establish camshafts in their substantive provision.

9 Turn a cranked shaft at least on two turns in an hour hand direction at loaded block VANOS. To turn a cranked shaft and accordingly the engine it is possible for one of next ways:

— Switch a check point in neutral position and tighten a lay brake. Turn a cranked shaft for the central bolt of fastening of a pulley in a direction of an hour hand by means of a head.
— Lift and establish the car on supports sideways behind. Include the fifth transfer and release a lay brake. Turn forward the lifted back wheel. Thus the cranked shaft simultaneously turns
— Establish the car on an equal platform. Include the fifth transfer. Cautiously shift or ask to shift the car forward.

10 Establish a cranked shaft in position ВМТ of the first cylinder. Tops of cams (an arrow on an illustration) inlet and final valves of the first cylinder (from outside drive ГРМ) should be turned upwards.

11 Fix a cranked shaft in position ВМТ by tool BMW or other suitable core. For this purpose insert a core into an aperture in the block of cylinders (the marksman on an illustration) in a flywheel aperture, having taken out preliminary a stopper in the block of cylinders.

12 Turn out hairpins (arrows on an illustration).

26 Remove both asterisks with a chain from camshafts.

27 Disconnect top натяжитель chains (arrows on an illustration).

28 Disconnect an asterisk from a camshaft.

Fix an asterisk a wire that it has not slipped downwards.


29 For removal of camshafts adaptation BMW 11 3 260 is required. It is intended for all bearings of camshafts in installation position when loose leaves of bearings are released. Operation of removal of both camshafts is identical, the sequence of removal of value has no.

30 Turn out spark plugs. Establish the adaptation and fix it in carving apertures of spark plugs of cylinders 1 and 4 moment 25 Н•м.

31 Turn a wrench эксцентриковый a shaft in a direction of an arrow and fix covers of bearings.

32 Oslabte bolts of fastening of all covers of bearings.

The cover of the first bearing of a camshaft of inlet valves is aligned by plugs. For an exception of a warp of a camshaft turn away bolts of fastening of a cover of the first bearing and remove it.

33 Oslabte the adaptation also remove it.

34 Remove covers of bearings and camshafts. Put covers as their installation on the engine. Installation of covers on the engine is necessary for executing in the same order. Covers of bearings of a camshaft of final valves have marks with А1 on А7, camshafts of inlet valves with Е1 on Е7 (arrows on an illustration).

35 If it is necessary, for example, for removal of valves, remove in the complete set a lath of bearings-2 with pushers. Pay attention to aligning plugs-2. Plancks of bearings in a point “2” have marks "And" for the party of release and “Е” for the admission party.

Pushers of valves can slip out downwards a lath of bearings if they are not fixed. HUNDRED BMW apply to this purpose of a sucker which can be established from above on a pusher and interfere выскальзыванию. Mark pushers. They should be established on a former place if were taken out from a lath. 1 - a head of cylinders.

Do not put the removed pushers more than on 10 mines on a head, otherwise from it impellent oil will flow out and automatic indemnification клапанных backlashes will cease to work.
