Belt of drive ГРМ - the general information, removal and installation
Exact adjustment of a tension drive can achieve a belt only with application of special tool Citroyon SEEM 4122. In the section text the description of a way of approximate adjustment (at the first possibility the car should be driven away on a car repair shop where correctness of installation can be checked up with application of the special equipment) is resulted. Try to avoid distant trips and movement with high speeds until the belt tension will not be adjusted properly.
The general information
The means газораспределительного a belt carry out a drive of a camshaft and the water pump. Rotation is transferred through cogwheels from a cranked shaft. Remember that breakage or проскальзывание газораспределительного a belt at the working engine leads to serious damages of a head of cylinders as a result of blow of plates of valves about the bottoms of pistons.
Replacement газораспределительного a belt should be made strictly according to the schedule of routine maintenance of the car (address to the Head Routine maintenance). Extraordinary replacement of a belt should be made in case of pollution by its oil, and also at occurrence of the scraping sounds testifying to non-uniform deterioration of a tape or teeths.
Simultaneously with belt change it is necessary to check up the water pump on presence of signs of leaks.
1. Disconnect a negative wire from the battery.
2. Поддомкратьте redock of the car also establish it on props. Remove the right forward wheel.
3. Release clamps, turn out fixing screws and remove локер.
4. Remove a belt of a drive of auxiliary units (address to the Head Routine maintenance). Also отболтите also remove натяжитель an auxiliary belt.
5. Отболтите also remove the top cover газораспределительного a belt (Removal and installation of covers газораспределительного a belt see).
6. Achieve combination of apertures for blocking of cranked and distributive shaft and pass in them metal cores of the corresponding diameter (Fixing cranked/distributive shaft for the purpose of prevention casual in the course of performance of procedures of service of the car see). At all do not suppose attempts проворачивания the engine after introduction of blocking cores.
7. Remove a pulley of a cranked shaft (Removal and installation of a pulley of a cranked shaft see).
8. On models 1.6 and 1.8 l remove the central cover газораспределительного a belt. On l models 2.0 отболтите also remove the bottom cover (Removal and installation of covers газораспределительного a belt see).
9. Release a bolt of fastening of a roller натяжителя газораспределительного a belt. By means of a special key of the square section passed in an aperture in a nave of a roller develop last clockwise and fix it in this position, again having tightened a fixing bolt.
10. If the belt acts in film not for the purpose of replacement performance, mark with a chalk or a paint a direction of its rotation (if the similar label is not put on manufacturer). Remove a belt from cogwheels. Remember that the cranked shaft should not be turned at removed газораспределительном a belt.
11. Attentively examine a belt on all its length, paying attention to traces of pollution by oil and signs of non-uniform deterioration. It is necessary to give special attention to a condition of the bases of teeths. It is necessary to replace a belt being in a doubtful condition without any fluctuations. If the engine requires major repairs, or its run makes more than 60 000 km (36 000 miles) a belt (if it has not been established recently) is subject to replacement without fail. Do not forget that cost of a new belt anything in comparison with the expenses connected with regenerative repair of the engine after an exit of its system as a result of breakage of a belt while in service of the car. At detection of traces of pollution of a belt by oil it is necessary to reveal a source of leak and to eliminate the reason of its development. Carefully wipe a surface of the power unit around installation газораспределительного a belt, completely having removed traces of oil from all accompanying components.
1. Before installation carefully clear cogwheels which it is put on газораспределительный a belt. Check up freedom of rotation of a roller натяжителя, in case of need replace last (Removal, check of a condition and installation натяжителя and cogwheels газораспределительного a belt see).
2. Make sure of presence on the place of the core blocking a cogwheel of a camshaft (Fixing cranked/distributive shaft for the purpose of prevention casual in the course of performance of procedures of service of the car see). Temporarily establish into place a pulley of a cranked shaft and pass a core of suitable diameter in its blocking aperture to make sure of correctness of position of a shaft (see in the same place).
3. Remove a pulley of a cranked shaft. Get газораспределительный a belt on the regular place, having tracked observance of a direction of its rotation (clockwise at a sight from the right board of the car).
4. Try not to overwind excessively at installation a belt. Throw with a belt cogwheels of distributive and cranked shaft. Track, that forward "run" of a belt has appeared will pull, i.e. all weak point should gather on the party натяжителя. Now put on a belt a cogwheel of the water pump and on a roller натяжителя. Track, that belt teeths have settled down in the central part of forming surfaces of cogwheels.
5. Temporarily establish into place a pulley of a cranked shaft, moderately having tightened a bolt of its fastening. Pass a core of suitable diameter in a blocking aperture (Fixing cranked/distributive shaft for the purpose of prevention casual in the course of performance of procedures of service of the car see).
Adjustment of a tension of a belt is made at the removed covers. For installation of covers into place it is necessary to remove a pulley of a cranked shaft once again.
6. Loosen the a bolt of fastening of a roller натяжителя. By means of a special key of square section develop a roller counter-clockwise, completely having chosen a belt weak point.
7. At presence near at hand special the adaptation for adjustment of a tension of a belt, establish it on forward "run" of the last. The roller натяжителя should be adjusted so that the initial tension of a belt made 16 ± 2 blocks of the adaptation for models 2.0 of l and 30 ± 2 blocks for models 1.6 and 1.8 l.
8. Take blocking cores and turn a cranked shaft on two complete revolutions in a direction clockwise (looking from the right board of the car). Again achieve combination of blocking apertures (Fixing cranked/distributive shaft for the purpose of prevention casual in the course of performance of procedures of service of the car see). At all do not turn a cranked shaft counter-clockwise. Drillings in a cogwheel distributive and a pulley cranked shaft should be combined with reciprocal apertures in a head and the block of cylinders so that in the last blocking cores of the corresponding diameter were freely passed. Performance of last condition gives a guarantee of correctness of installation of phases timing. Do not forget to take blocking cores.
9. If to achieve demanded combination of apertures it is not possible, repeat procedure of installation of a belt.
10. If adjustment of a tension of a belt has to be made without the special adaptation, try to achieve, that at the moderate effort put big and index fingers on a site in the middle of forward "run", the belt tape was overwound on 90 °. Infringement of the given condition is fraught with unexpected breakage of a belt (too hard tension), or проскальзывании it on cogwheels. Both that and another can lead to serious internal damages of the engine as a result of blow of valves about the bottoms of pistons. In case of need correct in appropriate way roller position натяжителя. In summary tighten a bolt of fastening of a roller with demanded effort.
11. If made adjustment of a tension of a belt with application of the special adaptation, turn a cranked shaft on two complete revolutions in a direction of normal rotation, then achieve combination of blocking apertures of a camshaft and pass in them a core of the corresponding diameter. Make sure that the belt tension on forward "run" makes 44 ± 2 blocks, otherwise repeat installation procedure.
12. Having achieved a correct tension of a belt, take a blocking finger from a camshaft cogwheel, then remove a pulley of a cranked shaft and establish into place a forward cover ().
13. Finalise into place a pulley of a cranked shaft for what grease a carving of its fixing bolt with fixing hermetic of type Loctite, then screw a bolt (do not forget about a washer) and tighten it with demanded effort (Removal and installation of a pulley of a cranked shaft see).
14. Establish into place натяжитель auxiliary drive a belt, then establish actually a belt and adjust effort of its tension (address to the Head Routine maintenance).
15. Establish into place локер, then the right forward wheel. Lower the car on the earth and tighten bolts of fastening of a wheel with demanded effort.
16. Connect a negative wire to the battery.
