Removal, check of a state and installation of cogwheels and natyazhitel of a belt of the GRM drive
General information
Before starting implementation of the procedure it is necessary to make an immobilization of the engine and car: a) Disconnect a negative wire from the battery.
|
If the stereosystem established on the car is equipped with the security device before disconnecting the battery make sure that you have the correct code for input of the audio system in action. |
b) Prop up wedges back wheels of the car and cock the parking brake. Transfer a control lever of RKPP to neutral situation;
Natyazhitel
REMOVAL
CHECK
|
Carefully clear a natyazhitel, in order to avoid pollution of the bearing without applying any solvents. Rotating a pulley for a nave manually, make sure of lack of breakthroughs and points of jamming. Existence of a side play testifies to wear of assembly and need of its replacement. |
|
INSTALLATION
|
|
1. Put on a roller a hairpin. The plate of the basis of a natyazhitel has to be put on by an U-shaped cut a bolt. Slightly tighten a lock-nut. |
2. Pull a GRM drive belt (see the Section Removal and installation of a belt of the GRM drive and its covers).
|
3. Check serviceability of functioning of a natyazhitel for what firmly press on a belt a thumb on the site in the middle between cogwheels of cranked and distributive shaft - the speaker from under a roller the sliding index will be displaced from an adjusting groove to an assembly basis plate aside. |
|
4. At a belt otpuskaniye the index has to return to a starting position, again having combined with a groove. In case of jamming of the index a natyazhitel it is necessary to replace. |
5. Install into place all removed components (see the Section Removal and installation of a belt of the GRM drive and its covers). 6. Upon termination of assembly check correctness of installation of a corner of an advancing of ignition (see the Head Elektrooborudovaniye of the engine). |
|
Camshaft cogwheel
REMOVAL
|
1. Uncover a gas-distributing belt and bring the piston of the first cylinder into the provision of VMT of the end of a step of compression. Having released a lock-nut of a natyazhitel, weaken a belt and remove it from a camshaft cogwheel.
|
In order to avoid damage of components of a head of cylinders as a result of the casual shift of a bent shaft in the course of removal/installation of a cogwheel of the camshaft, authors of the present manual recommend to develop a shaft by couple of degrees from VMT back. Before putting on of a belt do not forget to return the engine to the provision of the top dead point. |
|
2. Before an otdavaniye of a fixing bolt it is necessary to take care of blocking of a cogwheel of the camshaft. Use the elementary bifurcate capture made of two pieces of a metal strip and three nuts with bolts. One of bolts carries out a tool fork axis role, two others fasten to an asterisk. |
3. Having reliably blocked a cogwheel, give a fixing bolt.
|
4. Remove a cogwheel from a camshaft pin. |
5. Having removed a wheel, at once check a camshaft epiploon for existence of signs of leaks. In case of need make replacement of an epiploon (see the Section Replacement of an Epiploon of the Camshaft). 6. Carefully wipe the interfaced surfaces of a cogwheel and a pin of a shaft. |

ASSEMBLY
Cogwheel of a bent shaft
REMOVAL
ASSEMBLY
|
|
1. Having achieved combination of a tooth of a nave with a shponochny groove of a pin, establish a wheel into place. Having slightly greased a carving, screw a new fixing bolt and tighten it, so far only by hand.
|
Final tightening of a bolt is made after installation of a gas-distributing belt. The effort of tightening is rather high to exclude risk of a casual provorachivaniye of a shaft with inevitable removal of the engine from the provision of VMT. |
|
2. Make sure that the engine is in the provision of VMT (see the Section Reduction of the Piston of the First Cylinder in the provision of the top dead point (TDP) of the end of a step of compression), then establish a belt of the GRM drive and adjust effort of its tension (see the Section Removal and installation of a belt of the GRM drive and its covers). 3. Having blocked a bent shaft from a provorachivaniye, in stages tighten a bolt of fastening of a cogwheel of a bent shaft with the required effort.
4. Working as it should be, the return to a dismantle order, install the remained components and connect a negative wire to the battery. |

Gear belt of the water pump
The cogwheel is built in in assembly of the pump and in an individual order is not removed. The description of the procedure of the pump is provided in the Head of the Cooling system, heating. |
