Проворачивание the engine
|
|
For проворачивания a cranked shaft of the 4-cylinder engine manually it is necessary to put a key of 22 mm on a nut of a pulley of the generator. If the belt slips, it is necessary to press it. |
|
|
Nuts of a cover of a head of the block of cylinders of the 5-cylinder engine should be twirled in the represented sequence at first following moments of an inhaling 5 Nm, then 10 Nm, and in last turn 12 Nm. |
At the left: on the 5-cylinder engine crankshaft it is possible to turn a nut of a pulley of the generator (a key of 24 mm). If the belt slips a little, it is necessary to load it with a hand.
On the right: a cranked shaft of the 6-cylinder engine turn the central bolt of a pulley of a cranked shaft. As the tool the 12-faced replaceable face head of 24 mm with a rattle or the lever is applied.

|
ВМТ it is found, if the mark "About" has appeared on a flywheel under edge of the case of a transmission (arrow). |
At the left: one more mark ВМТ at 6-cylinder engines is located on a pulley or the bottom protective cover of a gear belt (arrow).
On the right: at ВМТ the moment of ignition of the first cylinder the big apertures of adjusting plates on both приводных camshaft gear wheels are directed to the middle of the engine (marksman).
For carrying out of some works it is necessary or to result a cranked shaft in certain position, or to turn it.

- For this purpose in the car with a mechanical transmission on an equal surface it is necessary to include the fifth transfer and to roll away the car a little forward or back.
- On the 4-cylinder engine to put bent накидной a key on 22 mm on the central nut of a pulley of the generator and to turn the engine through wedge a belt. If the belt slips, it is necessary for pressing through between pulleys a free hand and by that to pull.
- On the 5-cylinder engine to put рожковый a wrench of 24 mm on the central nut of a pulley of the generator and to turn the engine in the same way, as 4-cylinder.
- On the 6-cylinder engine to put a 12-faced replaceable face head of 24 mm on the central bolt of a pulley of a cranked shaft and to turn a cranked shaft a rattle or the lever.
- Never turn the engine for a bolt of fastening of a gear wheel of a gear belt on distributive to a shaft at the removed casing of a gear belt! The gear belt can jump, result – engine damages.

Installation of the cylinder 1 in position of the top dead point (ВМТ) the ignition moment
In the four-cycle engine the piston two times comes to the top dead point (ВМТ): the first time at ignition of the let in gas mixture and the second time after emission of the fulfilled gases with beginning in summary repeated всасывании fuel/air mixes. Usually at various adjusting works it is necessary ВМТ the moment of ignition of the first cylinder.

- 4-cylinder and 5-cylinder engines: to uncover, separating the breaker from the ignition distributor, бегунок the distributor of ignition and a protective cover. Again to put on бегунок the distributor and to turn the engine until contact бегунка will not be over a small label on the brink of the distributor. Thereby it is found ВМТ.
- That this business was possible more exact, possibly, it is required to turn a cranked shaft a little in one or other party while in in a viewing aperture of a transmission there will be no marks "About" on a flywheel at edge of a viewing aperture.
- The 6-cylinder engine: to remove a casing of a gear belt on the right and at the left (it is described more low in this chapter).
- To turn a cranked shaft until both apertures of fixing plates on both приводных camshaft gear wheels will not be established inside the friend opposite to the friend (in one line).
- A few to turn a cranked shaft in one or other party while in a viewing aperture of a cover of a transmission there will be no marks "About" on a flywheel at edge of a viewing aperture.

Removal of a protective cover of the engine
The 6-cylinder engine is supplied by a protective cover which carries out function шумоглушения. Removal:
|
|
- To turn four high-speed locks the big screw-driver on 90 to the left.
- To remove a protective cover.
|
|
Removal of a cover of a head of the block of cylinders
|
|
-
The 4-cylinder engine: on the engine capacity of 66 kw to remove the air filter.
- To remove a hose for removal of air from картера. To disconnect a plait of wires if is available.
- To weaken a cable of a drive of "gas" and to extend it from a support.
- To turn away fixing nuts.
- To remove rigidity overlays.
- To lift a cover.
- If necessary to remove маслоотражатель.
-
The 5-cylinder engine: from an inlet collector to remove a hose of the amplifier of brakes.
- To remove the top part of an inlet collector and впрыскные atomizers (the head System of injection KE-III-Jetronic).
- To remove the distributive valve of stabilisation of idling.
- To turn away fixing nuts, to remove rigidity overlays.
- To uncover.
-
The 6-cylinder engine: to remove engine protection.
- To turn away lock bolts.
- To raise a cover.
- If necessary to remove маслоотражатель.
- At installation to put a new lining.
-
4 and 5-cylinder engines: not to forget about a sheet overlay of rigidity under fixing nuts.
- The 6-cylinder engine: slightly to grease a lining of a cover of a head of the block of cylinders on internal and an outer side with silicone antifrictional means D 007 000 04.
- To put on all four sides between a sealing lining of a head of the block of cylinders and a cover of the bearing of a camshaft it is a little Silimate AMV 174 004 01 from a warehouse запчатей Audi. To watch that the aperture for oil below on a cover of the bearing of a camshaft thus was not hammered.
-
All types of engines: crosswisely to tighten the moment 10 Nm nuts or bolts, since the cover middle.
