Removal, check of a condition and installation натяжителя and cogwheels газораспределительного a belt

In the present section the description of procedures of dismantle of each of components in an individual order is resulted. If it is required to make full dismantling of drive ГРМ, begin with removal of a gear belt (the Belt of drive ГРМ - the general information, removal and installation see), then pass to dismantle of other components, operating as it is described more low, but lowering preparatory procedures.

Removal

 PERFORMANCE ORDER

1. Disconnect a negative wire from the battery.
2. 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.

Camshaft cogwheel

 PERFORMANCE ORDER

1. Remove the top cover газораспределительного a belt (Removal and installation of covers газораспределительного a belt see).
2. Loosen the a bolt of fastening of a roller натяжителя газораспределительного a belt. Having passed in a special aperture in a nave of a roller a key of square section, develop a roller clockwise and fix it in this position, again having tightened a fixing bolt.
3. Take a blocking core from drilling in a camshaft cogwheel. Throw off газораспределительный a belt from a cogwheel. Try not to admit excessive перегибания and перекручивания a belt tape.

4. Release a bolt of fastening of a cogwheel of a camshaft and remove it together a washer. Not to admit проворачивания a shaft during time отдавания a bolt, it is necessary to block a cogwheel by means of special вильчатого capture. At absence near at hand firm capture, it is possible to make the suitable adaptation independently of two pieces of a steel strip and three bolts with nuts. One болтовая pair will serve as the plug axis, two others are used for fastening of the ends by last to a cogwheel. Do not try to release at all a fixing bolt, having fixed a shaft by core introduction in a blocking aperture of a cogwheel as it is described in section Fixing cranked/distributive shaft for the purpose of prevention casual in the course of performance of procedures of service of the car!

5. Having turned out a fixing bolt, remove a cogwheel from a shaft pin. Freely filled landing pin should be taken from a back end face of a wheel and to clean in a reliable place. At once check up the epiploon of a camshaft located under a wheel on presence of signs of development of leaks. In case of need make replacement of a defective epiploon (epiploon Replacement (ов) a camshaft see).

Cogwheel of a cranked shaft

 PERFORMANCE ORDER

1. Remove the top, central and-or bottom covers газораспределительного a belt (Removal and installation of covers газораспределительного a belt see).
2. Loosen the a bolt of fastening of a roller натяжителя газораспределительного a belt. Having passed in a special aperture in a nave of a roller a key of square section, develop a roller clockwise and fix it in this position, again having tightened a fixing bolt.
3. Throw off газораспределительный a belt from a cogwheel, then remove the last from a pin of a cranked shaft. Take from a pin freely planted segment шпонку and clean it in a reliable place. At a corresponding complete set remove from a pin also the remote plug.
4. Check up the epiploon of a shaft located under a cogwheel on presence of signs of development of leaks, in case of need make replacement (Replacement of epiploons of a cranked shaft see).

Roller натяжителя

 PERFORMANCE ORDER

1. Remove top and, at a corresponding complete set, central covers газораспределительного a belt (Removal and installation of covers газораспределительного a belt see).
2. Loosen the a bolt of fastening of a roller натяжителя also remove last from the basic hairpin. Check up serviceability of a condition of a hairpin, in case of need make replacement.

Condition check

 PERFORMANCE ORDER

1. Carefully clear surfaces of cogwheels and attentively examine them. In case of revealing of signs of non-uniform deterioration of teeths, cracks and other mechanical damages replace a defective wheel.
2. Without application of solvents (in order to avoid washing away of greasing from the bearing) clear assemblage натяжителя. Check up freedom of rotation of a roller on a basis plate. In case of revealing of the slightest signs of deterioration or mechanical damages replace defective assemblage.

Installation

Camshaft cogwheel

 PERFORMANCE ORDER

1. If took, establish on the place in a back end face of a cogwheel a landing pin. Put on a wheel a camshaft pin, having tracked pin hit in a reciprocal groove in a shaft end face.

2. Screw a fixing bolt (do not forget about a washer) and tighten it with demanded effort. For fixing of a shaft in the course of a bolt tightening take advantage вильчатым of capture.

3. Achieve drilling combination in a cogwheel with a reciprocal aperture in a head of cylinders and pass in them a blocking core 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). Make sure that the core blocking a cranked shaft, also is on the regular place.
4. Throw a cogwheel газораспределительный with a belt. Track, that forward "run" of a belt has appeared will pull, and all weak point has gathered on the arrangement party натяжителя. Try not to bend and not to overwind a belt tape excessively. Make sure of correctness of landing of teeths of a belt on all wheels.
5. Correct image having arranged a belt on cogwheels, make adjustment of its tension (the Belt of drive ГРМ - the general information, removal and installation see).
6. In summary establish into place forward covers (Removal and installation of covers газораспределительного a belt see).

Cogwheel of a cranked shaft

 PERFORMANCE ORDER

1. At a corresponding complete set put on a pin of a cranked shaft the remote plug. Try not to damage an epiploon. Establish in a groove on a pin segment шпонку.
2. Having achieved groove combination in a nave with шпонкой, plant a cogwheel on a pin.
3. Make sure available on the place of the core blocking 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 achieve combination of its blocking drilling with a reciprocal aperture in the block (the core of the corresponding diameter should pass freely in both apertures - see in the same place).
4. Remove a pulley and throw газораспределительный with a belt a cogwheel of a cranked shaft. Track, that forward "run" of a belt has appeared will pull, and all weak point has gathered on the arrangement party натяжителя. Try not to bend and not to overwind a belt tape excessively. Make sure of correctness of landing of teeths of a belt on all wheels.
5. Make a belt tension (the Belt of drive ГРМ - the general information, removal and installation see).
6. Remove a pulley of a cranked shaft and establish into place a forward cover () (Removal and installation of covers газораспределительного a belt see).
7. Finalise into place a pulley of a cranked shaft (Removal and installation of a pulley of a cranked shaft see) and connect a negative wire to the battery.

Roller натяжителя

 PERFORMANCE ORDER

1. Put on a roller натяжителя the basic hairpin and fix its bolt.
2. Track, that forward "run" of a belt has appeared will pull, and all weak point has gathered on the arrangement party натяжителя. Make sure of correctness of landing of teeths of a belt on all wheels. Develop a roller натяжителя counter-clockwise, completely having chosen a belt weak point. Tighten a fixing nut.
3. Make a belt tension (the Belt of drive ГРМ - the general information, removal and installation see).
4. Establish into place a forward cover () (Removal and installation of covers газораспределительного a belt see).
