Removal
Bring the engine into VMT.
Remove a gear belt and a cam-shaft gear wheel, removal and installation of a gear belt, a tension.
Left head of the block of cylinders
Uncover GBTs.

Fig. 2.126 . Bolts of fastening of a cover of a gear belt


Turn off fixing bolts 1 and 2 and Remove a back cover of a gear belt (fig. 2.126) .

Right head of the block of cylinders
Uncover GBTs.
Remove by-pass a roller 1.

Fig. 2.127 . Bolts of fastening of a back cover of a gear belt


Turn off fixing bolts (see fig. 2.127 ) and remove a back cover of a gear belt.
Disconnect the tip from the sensor of the Hall and remove the case together with a cap and a cone.

Fig. 2.128 . Labels on cam-shafts


Check the provision VMT of cam-shafts. Marks in cam-shafts should coincide with both arrows on a bearing cover (fig. 2.128) .
At further use of an old roller chain of a drive of cam-shafts

Fig. 2.129 . Labels on a roller chain


Before removal mark a roller chain (fig. 2.129) (e.g. put with paint to the shooter specifying the direction of a course of a chain).

NOTE
Do not put on a chain of marks by means of a center punch and do not leave notches.


Fig. 2.130 . Fixing of a regulator of phases of a gazoraspredeleniye


Fix a regulator of phases of a gazoraspredeleniye by means of the holder for a natyazhitel of a chain 3366 (fig. 2.130) .

NOTE
At too strong inhaling of a natyazhitel of a chain the regulator of phases of a gazoraspredeleniye can be damaged.

Mark, as is shown in drawing, irrespective of put on covers of bearings of designation their assembly situation and sequence (e.g. a waterproof felt-tip pen).
Unscrew fixing bolts of a regulator of phases of a gazoraspredeleniye.
Uncover the bearing 1.

Fig. 2.131 . Sequence of removal of covers of bearings


Remove covers of bearings 2, 4, 6, 8 and 9 and according to sequence of removal (fig. 2.131) .
Put them on a pure surface.
Turn off covers of bearings 3, 5 and 7 in turn a cross on a cross and remove them.
Take both cam-shafts with a regulator of phases of a gazoraspredeleniye and put them on a pure surface.

Installation
Replace a semicircular stopper.
Replace laying of a regulator of phases of a gazoraspredeleniye.

Fig. 2.132 . Place of drawing of greasing


Slightly grease a vshity surface with AMV 188 001 02 hermetic (fig. 2.132) .
Put a roller chain on driving cogwheels of cam-shafts as follows.
At further use of an old roller chain of a drive of cam-shafts
Combine marks (fig. 2.129) .

When using a new chain of a drive of cam-shafts

Fig. 2.133 . Quantity of rollers between labels on asterisks of cam-shafts


The distance between grooves And and In should make 16 rollers of a chain. In drawing it is represented, in what places on cogwheels rollers 1 and 16 should be established. Rollers of a chain 1 and 16 are displaced opposite to grooves And and In everyone for 1/2 width of tooth to the left (fig. 2.133) .
Insert a regulator of phases of a gazoraspredeleniye between a roller chain of a drive of cam-shafts.
Enclose cam-shafts with the put-on roller chain and a regulator of phases of a gazoraspredeleniye in a head of the block of cylinders.
Grease flutes of cam-shafts with engine oil.

NOTE
The driven plugs for covers of bearings and a regulator of phases of a gazoraspredeleniye should be inserted into GBTs.

Establish covers of bearings 3, 5 and 7 according to designation and Fasten new bolts, alternating a cross on a cross. Inhaling moment: 5 N · m + to tighten on 1/4 about. (90 °)
Fasten a regulator of phases of a gazoraspredeleniye 10. Inhaling moment: 5 N · m + to tighten on 1/4 about. (90 °)
Establish a natyazhitel of a chain.

Fig. 2.134 . Combination of labels


Check the provision VMT of cam-shafts. Marks in cam-shafts should coincide with both arrows on a bearing cover (fig. 2.134) .

NOTE
That marks coincided, if necessary turn a cam-shaft forward and back a little.

Slightly grease a double cover of bearings 6 and a bearing 1 cover with AMV 188 001 02 hermetic and Establish both covers. Inhaling moment: 5 N · m + to tighten on 1/4 about. (90 °)
Establish other covers of bearings. Inhaling moment: 5 N · m + to tighten on 1/4 about. (90 °)
Replace epiploons of cam-shafts.
Replace epiploons of sensors of the Hall.
Accurately press a cover an emphasis of the tightening plug 3202.
Further installation is carried out in return sequence.

NOTE
After installation of cam-shafts the engine cannot be got within about 30 minutes of Gidrokompensatora to be осажены. (Otherwise there will be a contact of valves to pistons).
After works on the klapanny mechanism scroll the engine by hand to be convinced that any valve does not adjoin to the piston.


Fig. 2.135 . Places of drawing of greasing


Before installation put on joints of a lobby and a back cover of bearings a small amount of AMV 188 001 02 hermetic (fig. 2.135) .
