The engine of 2.4 l has a chain drive of a camshaft.
ENGINE ONS TO THE MIDDLE OF 1995 OF RELEASE
Check of a tension of a gear belt
Check and tension of a gear belt should be spent on the cold engine. This operation is spent differently for the engine with a tension roller of a gear belt and without a tension roller.
THE ENGINE WITH THE TENSION ROLLER OF THE GEAR BELT
| PERFORMANCE ORDER |
| 1. Remove вязкостную муфту with the fan and arms according to the description in corresponding subsection. |
| 2. Remove приводной a belt of the generator and the pump of the hydraulic booster of a steering. |
| 3. Remove a guard under the car. |
|
4. Turn out four bolts of fastening of a pulley of a cranked shaft. The pulley is kept from проворачивания by a face key, as is shown in иллюстр. |
| 5. Remove a forward cover of a gear belt. |
|
6. Turn a face key a cranked shaft in a rotation direction so that labels (2) have coincided (иллюстр.). Labels (1) on a cogwheel of a camshaft and a lath behind a gear belt Simultaneously should coincide. |
|
7. Check up приводной a pulley of the pump of a cooling liquid. Inflow on the pump should coincide with a corresponding ledge on the block of cylinders, as is shown in иллюстр. |
|
8. Check up a tension of a gear belt. A belt will pull normally if the index (2) is in 4 mm more to the left of a label (2) иллюстр. This check operates concerning the belt which was in the use. For a new belt other norm (see below section "Replacement of a gear belt") operates. |
| 9. If the tension of a gear belt does not correspond specified above, it is necessary to execute adjustment as it is described in section "Replacement of a gear belt". |
|
Now the engine can be collected. Bolts of fastening of a pulley tighten the moment of 20 Nanometers. Installation вязкостной муфты, клинового a belt is, etc. described in corresponding sections.
THE ENGINE WITHOUT THE TENSION ROLLER OF THE GEAR BELT
For check of a tension of a gear belt these engines have a special tool of firm Opel (№ КМ-510-А). If it is not present available check is carried out by the automobile owner on the basis of its private experience. However such tension demands after check in a repair truck.
Check of a tension of a belt is described more low in section "Replacement of a gear belt" for engines without a tension roller.
Replacement of a gear belt
THE ENGINE WITH THE TENSION ROLLER

Now the belt is weakened and can be removed. |
Instructions If the belt is supposed to be used again, it is necessary to exclude possibility of its contact to oil, greasing and an excess. Is better store a belt on a wall, having hung up on a nail.
|
|
9. Check up, that the camshaft and a cranked shaft were in the position shown on иллюстр. Otherwise very slowly turn a shaft (). Pistons can rest against valves. As soon as it will be felt, turn the second shaft back. |
| It is necessary to check up also приводной a pulley of the pump of a cooling liquid as it could turn incorrectly. Inflow on the pump case should coincide with a corresponding ledge on the block of cylinders. |
|
10. Put on a gear belt according to иллюстр. Point 1 on cogwheels. A branch of 1 belt should be tense. Now it is necessary to pull a belt. The belt is correctly tense, if the index (1) coincides with a label (2), as is shown in иллюстр. Further it is considered cases when the specified coincidence is not present. |
|
11. Ослабьте a bolt in the centre of a tension of a roller also turn the adjusting clown (1) on иллюстр. On the left so that the index (2) adjoined to the right emphasis. Again tighten a bolt of fastening of a roller (25 Nanometers). |
|
12. Turn a cranked shaft precisely on two turns (by means of a face key for a bolt of fastening of a pulley) and check up, whether the labels shown on иллюстр coincide. |
|
13. Slightly ослабьте a bolt of fastening of a tension roller also turn the adjusting clown to the right (clockwise) so that the index (1) and a label (2) lay opposite each other, as is shown in иллюстр. A bolt again tighten the moment of 25 Nanometers. |
| 14. Again turn a cranked shaft on two complete revolutions and check up position of labels and the index of the clown. |
|
Other works spend in return sequence. Демпфер крутильных fluctuations fix the moment of 20 Nanometers. Put on клиновой a belt taking into account a direction of its rotation and pull, as it is described in the Head of System of cooling and heating.
Establish into place all removed parts.
THE ENGINE WITHOUT THE TENSION ROLLER OF THE GEAR BELT
| PERFORMANCE ORDER |
| 1. Disconnect a cable of weight from the storage battery. |

9. Put on a new gear belt according to иллюстр. At first lay a belt on a wheel of a cranked shaft (1), then on wheels of a camshaft (2) and the pump of a cooling liquid (3).
4 – the Generator. |
| 10. Now establish a pulley of a cranked shaft. |
|
Adjust a tension of a gear belt. For check of a tension of a gear belt these engines have a special tool of firm Opel (№ КМ-510-А). If it is not present available check is carried out by the automobile owner on the basis of its private experience. However it demands after check in the conditions of a repair truck.
Check of a tension of a belt is described more low in section "Replacement of a gear belt" for engines without a tension roller.
Instructions The tension of the belt which was in the use is checked on the heated-up engine. The tension of a new belt is checked on the cold engine.
Check of a tension of a belt on the established engine is more low described.
| PERFORMANCE ORDER |
| 1. Shift the pump of a cooling liquid outside, having provided приводному to a belt certain freedom, and tighten bolts of fastening of the pump by hand. |
| 2. Establish on a bolt of fastening of a pulley of a cranked shaft a face head and turn a shaft from existing position at least on a turn quarter to the right. |
|
3a. The device for the control of a tension of the belt, shown on иллюстр. |
|
|
3b. Establish the device how it is shown on иллюстр. (Between wheels of the pump of a cooling liquid and a camshaft). |
| 4. Slowly release the device lever, knock two-three times on the device and read the instrument. Indications of the tool for cold and heated-up engines are more low resulted. It is not necessary to confuse them. |
| 5. If the instrument reading does not correspond resulted above, ослабьте bolts of fastening of the pump of a cooling liquid and turn the pump. Turn outside raises a belt tension, turn inside reduces a tension. Bolts of fastening of the pump again tighten manually (the pump it is impossible to move more). |
| 6. Remove the device and turn a cranked shaft on two complete revolutions to the right. Again check up a belt tension in the way described above. If it corresponds to the values resulted above, tighten bolts of fastening of the pump. Establish to the place of a cover of a gear belt. Fix a plait of cables on a cover. |
| 7. If specified above the device for the control of a tension of a belt is not present, the tension is checked manually on a belt branch between wheels of the pump of a cooling liquid and a camshaft. For this purpose a belt tape try to turn big and index hand fingers. If the belt is possible to turn on on 90 °, the tension is adjusted truly. It is better to draw some a belt, than недотянуть it. Poorly tense belt can jump on wheel teeths. Tension adjustment is necessary for executing also on the pump of a cooling liquid. Not additional checks will be superfluous. Control check is necessary for executing in a repair truck. Перескакивание a belt on teeths can lead to heavy damages of the engine and, at least, to expensive repair. |
