4.1.7. Removal, check of a state 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 full dismantling of the GRM drive, begin with removal of a gear belt (see a GRM drive Belt - the general information, removal and installation), then you pass to dismantle of other components, working as it is described below, but lowering 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 throughout them metal cores of the corresponding diameter (see Fixing cranked/distributive in bulk for the purpose of prevention of service of the car, casual in the course of performing procedures). Do not allow attempts of a provorachivaniye of the engine after introduction of blocking cores at all.

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 throughout a special opening in a roller nave a key of square section, develop a roller clockwise and record 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 excessive bending and twisting of a tape of a belt.

4. Release a bolt of fastening of a cogwheel of the 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 company capture, it is possible to manufacture suitable adaptation independently of two pieces of a steel strip and three bolts with nuts. One bolted couple will serve as a fork axis, two others are used for fastening of the ends of the last to a cogwheel. Do not try to release a fixing bolt at all, having recorded a shaft by introduction of a core to a blocking opening of a cogwheel as it is described in the section Fixing cranked/distributive in bulk for the purpose of prevention of service of the car, casual in the course of performing procedures!

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 remove to the reliable place. At once check the camshaft epiploon located under a wheel for existence of signs of development of leaks. In case of need make replacement of a defective epiploon (see Replacement of an epiploon(s) of the camshaft).

Cogwheel of a bent shaft

 PERFORMANCE ORDER

1. Uncover top, central and/or lower 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 throughout a special opening in a roller nave a key of square section, develop a roller clockwise and record 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 bent shaft. Take freely put segment spline from a pin and move away her to the reliable place. At the corresponding complete set remove also remote plug from a pin.
4. Check the shaft epiploon located under a cogwheel for existence of signs of development of leaks, in case of need make replacement (see Replacement of epiploons of a bent 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.

Check of a state

 PERFORMANCE ORDER

1. Carefully clear surfaces of cogwheels and attentively examine them. In case of identification of signs of uneven wear of teeths, cracks and other mechanical damages replace a defective wheel.
2. Without use of solvents (in order to avoid washing away of lubricant 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 hit of a pin in a reciprocal groove in a shaft end face.

2. Screw a fixing bolt (do not forget about a washer) and tighten it with the required effort. For fixing of a shaft in the course of tightening of a bolt use bifurcate capture.

3. Achieve combination of drilling in a cogwheel with a reciprocal opening in a head of cylinders and pass throughout them a blocking core of the corresponding diameter (see Fixing cranked/distributive in bulk for the purpose of prevention of service of the car, casual in the course of performing procedures). Make sure that the core blocking a bent shaft also is in the regular place.
4. Throw with a gas-distributing belt a cogwheel. Track that forward "run" of a belt was tense, and all weak point gathered on the party of an arrangement of a natyazhitel. Try not to bend and not to overwind a tape of a belt excessively. Make sure of correctness of landing of teeths of a belt on all wheels.
5. Having arranged the correct image a belt on cogwheels, make adjustment of its tension (see a GRM drive Belt - the general information, removal and installation).
6. In conclusion establish into place forward covers (see Removal and installation of covers of a gas-distributing belt).

Cogwheel of a bent shaft

 PERFORMANCE ORDER

1. At the corresponding complete set put on the remote plug a pin of a bent shaft. Try not to damage an epiploon. Establish in a groove on a pin a segment spline.
2. Having achieved combination of a groove in a nave with a spline, put a cogwheel on a pin.
3. Make sure available on the place of the core blocking the camshaft (see Fixing cranked/distributive in bulk for the purpose of prevention of service of the car, casual in the course of performing procedures). Temporarily establish into place a pulley of a bent shaft and achieve combination of its blocking drilling with a reciprocal opening in the block (the core of the corresponding diameter has to 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 bent shaft. Track that forward "run" of a belt was tense, and all weak point gathered on the party of an arrangement of a natyazhitel. Try not to bend and not to overwind a tape of a belt excessively. Make sure of correctness of landing of teeths of a belt on all wheels.
5. Make a belt tension (see a GRM drive Belt - the general information, removal and installation).
6. Remove a pulley of a bent shaft and establish into place a forward cover (i) (see Removal and installation of covers of a gas-distributing belt).
7. Finalize into place a pulley of a bent shaft (see Removal and installation of a pulley of a bent shaft) and 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 by a bolt.
2. Track that forward "run" of a belt was tense, 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 counterclockwise, having completely chosen a belt weak point. Tighten a fixing nut.
3. Make a belt tension (see a GRM drive Belt - the general information, removal and installation).
4. Establish into place a forward cover (i) (see Removal and installation of covers of a gas-distributing belt).
