GRM drive - the general information, service of components
|
|
Camshafts can be turned without risk of collision of valves with pistons in a case when the cranked shaft is given in situation 30 ° before VMT of the piston of the first cylinder.
|
|
|
The gas-distributing chain can be replaced without engine dismantling. By means of listed below tools the new chain can be connected to old, is passed round asterisks and зачеканена. |
|
|
At the wrong assembly there can be a collision of valves with the bottoms of pistons! |
General information Details of installation of elements of a drive of GRM (the gas-distributing chain consists of 126 links)
|
|
1 — Adjusting labels for engine reduction in the provision VMT of the end of a step of compression of the first cylinder
2 — Cores in diameter of 4 mm for fixing of camshafts
3 — during installation of a chain track, that ledges of a regulator of a camshaft [3] were in the situation "delays".
4 — Podpruzhinennaya a nut of a natyazhitel |
5 — the Pin
6 — the Spring
7 — Plunzher
8 — the Case of a natyazhitel |

The tool for flywheel blocking / a driving disk - No. 601589024000;
Bolts М6ґ90 for fixing of the instrument of blocking of a flywheel / a driving disk;
The tool for installation of links of a gas-distributing chain - No. 602589003900;
Set of shtampoderzhatel for installation of links of a gas-distributing chain - No. 112589096300;
Stripper of links of a gas-distributing chain (element 1) - No. 602589023300;
Stripper of links of a gas-distributing chain (element 2) - No. 602589056300;
The holder of a stripper of the vyazkostny coupling (series 129/140) - No. 120589020100.
Pay attention to the next moments:
If the return is not stipulated especially, turn the engine only in the normal direction;
Observe the efforts of a tightening of fixture stipulated by standards;
At the corresponding complete set do not forget to mark before removal adjusting position of the CKP sensor;
Do not turn a cranked shaft for asterisks of camshafts, and also other asterisks of a drive of GRM;
Do not turn cranked and camshafts at the removed gas-distributing chain.
