The prevention If натяжитель it is weakened on шестиграннике it should be removed, differently at screwing up the operating chain will be unduly tightened.
Removal
THE 4-CYLINDER ENGINE
| PERFORMANCE ORDER |
|
1. Remove hydraulic муфту the fan. |
| 2. Uncover heads of the block of cylinders. |
| 3. Remove a fan casing. |
| 4. Establish the engine on 20 ° more low ВМТ ignitions of the first cylinder. For this purpose translate a transmission in position of idling and tighten a lay brake. Turn a cranked shaft by means of a wrench with nozzle SW27 at the central bolt of a belt pulley of a cranked shaft in a direction of rotation of the engine, i.e. Clockwise, before coincidence of marks. The length of a nozzle of a wrench should be more than 42 mm. |

| PERFORMANCE ORDER |
| 1. Fasten to the motor block the case натяжителя chains (14) with a new sealing ring (15). The moment of an inhaling for the 4-cylinder engine – 80 Н.м., for 6-cylinder – 50 Н.м. |
| 2. Collect details (7–10) as before their dismantling, and insert in mounted натяжитель chains. |
| 3. Twirl a screw stopper (1) with a new condensing ring (5) with the moment 40 Н.м., the spring is thus compressed. |
