Removal of a gear belt
| PERFORMANCE ORDER |
| 1. To disconnect from the accumulator a weight wire. |
| 2. To remove maple a belt of a drive of the generator. |
| 3. To disconnect a plait of electric wires of system of ignition, to remove the distributor of a high voltage, a rotor of the distributor and the holder of the distributor of ignition (see fig. System of a gazoraspredeleniye of the CVH engine). |
| 4. To remove a casing of a drive of system of a gazoraspredeleniye. |
| 5. To turn a cranked shaft before sign installation on a cam-shaft pulley opposite to a sign on a head of the block of cylinders (1) (see fig. Installation of a gazoraspredeleniye of the CVH engine). |
| 6. To weaken a bolt of blocking of the tension device of a gear belt. To move a roller to the left and to tighten blocking bolt. |
| 7. To remove a gear belt. |
|
Adjustment of a gazoraspredeleniye and installation of a gear belt
| PERFORMANCE ORDER |
| 1. To establish a sign on a cam-shaft pulley opposite to a sign on a head of the block of cylinders (1) (see fig. Installation of a gazoraspredeleniye of the CVH engine). |
| 2. To turn a cranked shaft before installation of a sign of a pulley of a cranked shaft (2) opposite to a sign on a case of the oil pump. |
| 3. To insert a spring of the tension device, the tension device and to block it in situation against the stop to the left. |
Prevention
This spring is not established at plant, the gear belt stretches by means of the special adaptation. After weakening of fastening of the tension device it is necessary to establish surely a spring for providing the correct tension of a gear belt.
|
| 4. To put on a gear belt, beginning from a pulley of a cranked shaft, in the direction counter-clockwise. |
| 5. To unblock the tension device so that its roller pulled a gear belt. |
| 6. To execute two complete revolutions of a cranked shaft in the direction clockwise and to establish a sign on a cam-shaft pulley opposite to a sign on a head of the block of cylinders. |
7. To fix a cranked shaft (having included transfer and having tightened the lever of the hand brake) and to rotate a cam-shaft in the direction counter-clockwise by means of a dinamometrichesky natural a head of 41 mm (through a reduktsionny element 1/2 "–3/4").
Prevention
The head of 41 mm is necessary, as it is impossible to rotate a cam-shaft for a bolt of fastening of its pulley.
|
| 8. To hold a cam-shaft with the moment of 23-30 Nanometers and to tighten the tension device of a gear belt the moment of 23-30 Nanometers (at first a bolt on the right side). |
| 9. To check, whether adjusting signs underwent change. |
| 10. To switch off transfer and the hand brake. |
| 11. To turn on two turns a cranked shaft in the direction of its working rotation, then repeatedly to check the provision of adjusting signs. |
| 12. To establish a casing of a drive of system of a gazoraspredeleniye. |
| 13. To establish the distributor of ignition and a wire of a high voltage. |
| 14. To put on and pull a maple belt of a drive of the generator. |
| 15. To connect the accumulator. |
