Prevention
If the old gear belt is established, by all means to pay attention to the direction of the movement. Installation of a gear belt in the opposite direction can lead to its rupture and breakages of the engine!
|
| 1. To put on a gear belt a gear wheel of the crankshaft, bypass a roller and a water pomp. |
| 2. To screw a vibroquencher 4 bolts the moment of 20 N · m. |
| 3. To screw the lower casing of a gear belt. Otherwise to turn a cam-shaft so that the tag on a driving gear wheel of a cam-shaft coincided with the upper edge of laying of a cover of a head of the block of cylinders. |
Prevention
If the cam-shaft is turned at the taken-off, gear belt, then any piston should not be in VMT. Otherwise there can come heavy damages of pistons or valves.
If it is necessary to turn a cam-shaft, then before install all pistons on identical height. For this purpose to put from above on a belt pulley of the crankshaft a cretaceous tag (a preliminary condition: the crankshaft costs in the provision of VMT for 1 cylinder), then to turn a belt pulley of the crankshaft on 1/4 turns (90 °) to the left or to the right, being guided on a cretaceous tag.
|
| 4. To check position of the crankshaft in VMT for the 1st cylinder. In a viewing opening of a case of coupling the tag of BMT (0) on a flywheel standing precisely near the adjusting edging has to be visible. |
| 5. If the gear belt is established on the removed engine, then the notch on a belt pulley has to coincide with an adjusting tag on a cover of a head of the block of cylinders. In this case the crankshaft is in the provision of VMT for 1 cylinder. |
| 6. To put on a gear belt. |
Prevention
At installation of a gear belt it is impossible to change the provision of a cam-shaft and the crankshaft. Otherwise the engine can sustain heavy damage or will not develop full capacity. After a tension of a gear belt to double-check the provision of a cam-shaft and the crankshaft. It means: if the tag on a cogwheel of a cam-shaft coincides with the top edging of laying of a cover of a head of the block of cylinders, then at the same time marking of VMT on a flywheel has to coincide with the tag corresponding to it. Otherwise to repeat adjustment of a driving gear wheel of a cam-shaft and gear wheel of the crankshaft.
|
| 7. To pull a gear belt. |
| 8. To turn the crankshaft on 2 turnovers of the direction of its rotation and to double-check adjustment and a tension. |
| 9. To establish the top casing of a gear belt. |
| 10. To screw the tension device of a maple belt. |
| 11. To establish and pull maple a belt. |
| 12. To establish an engine mudguard. |
13. At repairs which demand removal of a gear belt only from a cam-shaft cogwheel, to make adjustment of a gear belt as follows:
– to install the crankshaft in the provision of VMT for 1 cylinder;
– to weaken and take off a gear belt from a cam-shaft cogwheel;
– to put on and pull a gear belt;
– during repair not to change the provision of a cam-shaft and the crankshaft any more. |
