Removal, check of a condition and installation of a natyazhitel and cogwheels of a gas-distributing belt

In the present section the description of procedures of dismantle of each of components is provided in an individual order. If it is required to make complete dismantling of a drive of GRM, begin with removal of a gear belt (see. A belt of a drive of GRM - the general information, removal and installation), then pass to dismantle of other components, operating as it is described below, but omitting preparatory procedures.

Removal

 PERFORMANCE ORDER

1. Disconnect a negative wire from the battery.
2. Achieve combination of openings for blocking of cranked and distributive shaft and pass in them metal cores of the corresponding diameter (see. Fixing cranked/distributive shaft for the purpose of prevention casual in the course of performance of procedures of service of the car). At all do not allow attempts of a provorachivaniye of the engine after introduction of blocking cores.

Camshaft cogwheel

 PERFORMANCE ORDER

1. Remove the top cover of a gas-distributing belt (see. Removal and installation of covers of a gas-distributing belt).
2. Weaken a bolt of fastening of a roller of a natyazhitel of a gas-distributing belt. Having passed in a special opening in a roller nave a key of square section, develop a roller clockwise and fix it in this situation, again having tightened a fixing bolt.
3. Take a blocking core from drilling in a camshaft cogwheel. Throw off a gas-distributing belt from a cogwheel. Try not to allow an excessive peregibaniye and a perekruchivaniye of a tape of a belt.

4. Release a bolt of fastening of a cogwheel of a camshaft and remove it together a washer. Not to allow a shaft provorachivaniye during a bolt otdavaniye, it is necessary to block a cogwheel by means of special bifurcate capture. In the absence of 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 boltovy pair will serve as the fork axis, two others are used for fastening of the ends by the last to a cogwheel. Do not try to release at all a fixing bolt, having fixed a shaft by core introduction in a blocking opening of a cogwheel as it is described in the section Fixing cranked/distributive in bulk 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 the epiploon of a camshaft located under a wheel on existence of signs of development of leaks. In case of need make replacement of a defective epiploon (see. Epiploon replacement (ов) camshaft).

Cogwheel of a cranked shaft

 PERFORMANCE ORDER

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

Roller of a natyazhitel

 PERFORMANCE ORDER

1. Remove top and, at the corresponding complete set, central covers of a gas-distributing belt (see. Removal and installation of covers of a gas-distributing belt).
2. Weaken a bolt of fastening of a roller of a natyazhitel and remove the last from the basic hairpin. Check 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 identification of signs of non-uniform wear of teeths, cracks and other mechanical damages replace a defective wheel.
2. Without application of solvents (in order to avoid greasing washing away from the bearing) clear assembly of a natyazhitel. Check freedom of rotation of a roller on a basis plate. In case of identification of the slightest signs of wear or mechanical damages replace defective assembly.

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 shaft fixing in the course of a tightening of a bolt use bifurcate capture.

3. Achieve drilling combination in a cogwheel with a reciprocal opening in a head of cylinders and pass in them a blocking core of the corresponding diameter (see. Fixing cranked/distributive shaft for the purpose of prevention casual in the course of performance of procedures of service of the car). Make sure that the core blocking a cranked shaft, also is on the regular place.
4. Throw a cogwheel with a gas-distributing belt. Track, that forward "run" of a belt appeared will pull, and all weak point gathered on the party of an arrangement of a natyazhitel. 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. The correct image having arranged a belt on cogwheels, make adjustment of its tension (see. A belt of a drive of GRM - the general information, removal and installation).
6. In summary establish into place forward covers (see. Removal and installation of covers of a gas-distributing belt).

Cogwheel of a cranked shaft

 PERFORMANCE ORDER

1. At the 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 a segment shponka.
2. Having achieved groove combination in a nave with a shponka, plant a cogwheel on a pin.
3. Make sure available on the place of the core blocking a camshaft (see. Fixing cranked/distributive shaft for the purpose of prevention casual in the course of performance of procedures of service of the car). Temporarily establish into place a pulley of a cranked shaft and achieve combination of its blocking drilling with a reciprocal opening in the block (the core of the corresponding diameter should pass freely in both openings - see in the same place).
4. Remove a pulley and throw with a gas-distributing belt a cogwheel of a cranked shaft. Track, that forward "run" of a belt appeared will pull, and all weak point gathered on the party of an arrangement of a natyazhitel. 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 (see. A belt of a drive of GRM - the general information, removal and installation).
6. Remove a pulley of a cranked shaft and establish into place a forward cover (and) (see. Removal and installation of covers of a gas-distributing belt).
7. Finalize into place a pulley of a cranked shaft (see. Removal and installation of a pulley of a cranked shaft) also connect a negative wire to the battery.

Roller of a natyazhitel

 PERFORMANCE ORDER

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