2.1.5.1. Drive of the gas-distributing mechanism

GENERAL INFORMATION

Drive of the mechanism of a gazoraspredeleniye

1–camshaft asterisk;
2–a rotor of impulses for the Hall sensor;
3–bolt of fastening of an asterisk of a camshaft, 100 Nanometers. Before a vvinchivaniye of a bolt grease the bottom surface of a head of a bolt with a thin layer of engine oil. At a tightening of a bolt hold from a provorachivaniye a camshaft SW 24 wrench;
4–rotary finger, 18 Nanometers;
5–sealing ring. At damages use a new sealing ring;
6–device of a tension of a chain, 40 Nanometers;
7–level of the tension device;
8–asterisk of a driving chain;
9–dvukhryadny vtulochno-roller chain. Before removal of a chain note the direction of rotation of a chain;
10-bolt, 100 Nanometers;
11-asterisk of a driving chain;
12-bolt, 10 Nanometers;
13-the device of a tension of a chain with a level. Before removal of the device of a tension of a chain by a screw-driver release fixing gear gearing and separate directing to a chain from the tension device. To turn the engine it is possible only with the established device of a tension of a chain;
14-leading asterisk of a chain. In position VMT of the piston of 1 cylinder, the cut-off tooth should be on one line with the socket of a cover of the radical bearing No. 1;
15-single-row roller chain. Before removal of a chain note the direction of rotation of a chain;
16-level of an uspokoitel;
17-a hairpin for a level of an uspokoitel, 10 Nanometers;
18-a directing finger with a fillet, 10 Nanometers;
19-bolt, 20 Nanometers. The bolt is established by means of the special VW-D6 tool;
20-bolt, 20 Nanometers;
21-level of an uspokoitel;
22-bolt, 20 Nanometers. The bolt is established by means of the special VW-D6 tool;
23-adjusting washer;
24-intermediate shaft

Arrangement of elements of the gas-distributing mechanism at installation of the piston of the first cylinder in the top dead point in a compression step

1–chain;
2–directing to a chain;
3–forward asterisk of an intermediate shaft;
4–back asterisk of an intermediate shaft;

And – a clamp of the mechanism of a tension of a chain;
In – adjusting tooth on an asterisk of a cranked shaft should be on one line with the socket of a cover of the radical bearing No. 1;
With – an adjusting label on an asterisk of an intermediate shaft;
D–an adjusting label on an asterisk of an intermediate shaft

Places of drawing of labels before removal of chains of a drive of the mechanism of a gazoraspredeleniye

Before removal of chains of a drive of the mechanism of a gazoraspredeleniye, using paint, put labels on chains in the places shown in drawing.

The drive of camshafts is carried out from a cranked shaft, not directly, and through an intermediate asterisk. On one shaft with an intermediate asterisk the asterisk of smaller diameter through which and the second chain the gazoraspredeleniye mechanism is put in action is fixed. The top chain of a drive of camshafts stretches by means of the lamellar device of a tension which keeps in demanded situation with the help located outside of an adjusting bolt. The bottom chain of a drive of the mechanism of a gazoraspredeleniye has the hydraulic device of a tension which does not demand adjustment.

Removal

PERFORMANCE ORDER
1. Turn a cranked shaft of the engine in such situation at which the piston of the first cylinder will be established in the top dead point. Thus the adjusting label (it is specified by an arrow) on a pulley / quencher of fluctuations of a cranked shaft should be combined with the index on a chain casing.
2. At installation of the piston of the first cylinder in VMT on asterisks of an intermediate shaft the groove (it is specified by an arrow) should be visible. If groove on an asterisk of an intermediate shaft it is not visible, turn a cranked shaft of the engine on one complete revolution and repeatedly combine adjusting labels with indexes.
3. Fix camshafts, having inserted the special VW-3268 tool into grooves of camshafts.
4. When unscrewing a bolt of fastening of an asterisk of a camshaft, using a wrench, for лыски (are specified by shooters) hold a camshaft from a provorachivaniye.
