Removal and installation of camshafts

Camshafts at 4-клапанного the engine can act in film, if, for example, it is necessary to weaken bolts of fastening of a head of cylinders. As the special BMW tool for this purpose is required, it is recommended to carry out this operation on HUNDRED BMWs.

At installation without the special tool there is a danger of damage of camshafts. Besides, valves can be погнуты at contact with the bottoms of pistons.

All elements of a klapanny drive, for example, loose leaves of bearings or tarelchaty springs and gear plugs on asterisks should be established on their former places. For this purpose they are necessary for placing on the special pallet.

 REMOVAL

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

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

4 Unscrew bolts of fastening and uncover heads of cylinders (an arrow on an illustration). Thus pay attention to rubber laying of bolts of fastening that late it is correct to establish them.

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

7 Disconnect an oil pipeline (the shooter on an illustration) at the double VANOS block.

8 Instead of an oil pipeline attach to the double VANOS block the compressed air through the corresponding adapter and submit air pressure from 2 to the 8th bar.

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

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

— Switch a check point in neutral situation and tighten the parking brake. Turn a cranked shaft for the central bolt of fastening of a pulley in the 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 the parking brake. Turn forward the lifted back wheel. Thus the cranked shaft at the same time turns
— Establish the car on an equal platform. Include the fifth transfer. Carefully shift or ask to shift the car forward.

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

11 Fix a cranked shaft in situation VMT by the BMW tool or other suitable core. For this purpose insert a core into an opening in the block of cylinders (the shooter on an illustration) in a flywheel opening, having taken out previously a stopper in the block of cylinders.

23 Unscrew three nuts of fastening of the sensor on an asterisk of a camshaft of final valves. Remove a sensor wheel from a tarelchaty spring from an asterisk.

24 Unscrew fastening nuts (arrows on an illustration) on an asterisk of a camshaft of inlet valves. Remove a persistent washer from an asterisk.

Before an otvorachivaniye of nuts of fastening of an asterisk of a camshaft of final valves lead round nuts a felt-tip pen that at installation an asterisk to fix in its former situation. Otherwise it is correct to expose asterisks it will be possible only by means of the special BMW tool.

25 Unscrew three bolts of fastening of an asterisk of a camshaft of final valves.
26 Remove both asterisks with a chain from camshafts.

27 Disconnect the top natyazhitel of a chain (an arrow on an illustration).

28 Disconnect an asterisk from a camshaft.

Fix an asterisk a wire that it did not slip down.


29 removal of camshafts needs the BMW 11 3 260 adaptation. It is intended for all bearings of camshafts in the provision of installation 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 openings of spark plugs of cylinders 1 and 4 the moment of 25 N • m.

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

32 Weaken 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 distortion of a camshaft unscrew bolts of fastening of a cover of the first bearing and remove it.

33 Weaken the adaptation and 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 marking with А1 on А7, camshafts of inlet valves with Е1 on Е7 (shooters on an illustration).

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

Pushers of valves can slip out down a level of bearings if they are not fixed. HUNDRED BMWs apply to this purpose of a sucker which can be established from above on a pusher and interfere with a vyskalzyvaniye. Mark pushers. They should be established on a former place if were taken out from a level. 1-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 compensation of klapanny gaps will cease to work.
