Removal
Use of a steel core for fixing of the mechanism of a tension in the taken-away situation
| PERFORMANCE ORDER |
| 1. Remove a weight wire from the accumulator. |
| 2. On models with the amplifier of steering take off a driving belt of the pump of the amplifier of steering. |
| 3. Take off a driving belt of the generator. |
| 4. On C16 NZ2 1,8 and 2,0 engines of l disconnect the electric socket from the sensor of the index of temperature. |
| 5. Release brackets of fixing or unscrew screws with six-sided heads and remove the main external casing of a gear belt, then disconnect a smaller casing from the water pump. On some models the basic external casing fastens three bolts to a back casing, and the fourth bolt also the tension mechanism fixes. |
| 6. For release of the mechanism of a tension of a gear belt turn the tension mechanism indicator lever clockwise before combination of openings in a basic plate and the lever and insert a steel core of the corresponding diameter into an opening (see rice. Use of a steel core for fixing of the mechanism of a tension in the taken-away situation). In this position of the mechanism of a tension it is possible to unscrew the mechanism of a tension or to take off a gear belt. |
| 7. Check that the roller of the mechanism of a tension rotates smoothly and without jammings. Check that on a roller there were no signs of wear or damages. If there is a suspicion that the mechanism of a tension is worn-out or the spring weakened, it is necessary to replace the tension mechanism assembled. |
|
Installation
| PERFORMANCE ORDER |
| 1. At installation of the mechanism of a tension check that the ledge of a basic plate of the mechanism of a tension was combined with an opening in the case of the oil pump, then screw up a bolt of the mechanism of a tension and take the blocking core. At the same time the mechanism of a tension has to move freely. |
| 2. Adjust a tension of a gear belt. |
|
Adjustment
Use of a special key for turn of the water pump at adjustment of a tension of a gear belt
Combination of a tag (A) on a pulley of a bent shaft with the index on a back casing of a gear belt (B)
Combination of a tag (A) on a camshaft pulley with the index on a back casing of a gear belt (B)
Tension of a gear belt
| PERFORMANCE ORDER |
| 1. After removal of a gear belt or weakening of its tension it is necessary to adjust a belt tension only on the cold engine. |
| 2. In case the gear belt and pulleys of a gear belt, and also the tension mechanism was removed, check that the piston of the first cylinder is in VMT in a compression step. Temporarily establish a pulley of an auxiliary driving belt on a bent shaft and fix it by a bolt. Unscrew spark plugs in order that the bent shaft was easily turned. |
| 3. For simplification of turn of the water pump with the required accuracy it is necessary to use a special key of KM-421-A (see rice. Use of a special key for turn of the water pump at adjustment of a tension of a gear belt). |
| 4. Establish a gear belt and check that tags on a pulley of a bent shaft and the camshaft are combined with indexes (see rice. Combination of a tag (A) on a pulley of a bent shaft with the index on a back casing of a gear belt (V), Combination of a tag (A) on a camshaft pulley with the index on a back casing of a gear belt (V)). |
| 5. Pull a gear belt for what weaken three bolts of fastening of the water pump and turn the water pump clockwise until openings in the lever of the indicator of the mechanism of a tension and a basic plate are combined. At the same time the lever of the indicator of the mechanism of a tension will have an opportunity to move clockwise against the stop. Tighten bolts of fastening of the water pump so that the pump could not move. |
| 6. A wrench for a bolt of fastening of a pulley of a bent shaft, smoothly turn a bent shaft on two whole revolutions clockwise before combination of adjusting tags on pulleys with indexes. At a provorachivaniye of a bent shaft position of the water pump should not change. |
| 7. Weaken a tension of a gear belt, turning the water pump counterclockwise to such situation until the index of the indicator of the mechanism of a tension is established in the center of a groove of a basic plate. In this situation the tension of a gear belt is considered correctly adjusted (see rice. Tension of a gear belt). Tighten bolts of fastening of the water pump the required moment and turn a bent shaft on two whole revolutions clockwise and repeatedly check a tension of a gear belt. |
| 8. If the index was not combined with the center of a groove of a basic plate, repeatedly make adjustment of a tension of a gear belt. |
