GENERAL INFORMATION

Synchronizing tags of a bent shaft

Tags are specified by shooters.

Synchronizing tags of the camshaft – a forward number of cylinders

Tags are specified by shooters.

Synchronizing tags of the camshaft – a back row of cylinders

Tags are specified by shooters.

Removal

PERFORMANCE ORDER
1. Disconnect a wire of the minus plug of the accumulator.
2. Weaken a bolt of a pulley of the water pump. Take off a driving belt of the pump of system of hydrostrengthening of a wheel and a driving belt of the generator. Remove a pulley of the water pump.
3. Install the N1 piston in VMT.
4. Weaken bolts of a forward right wheel.
5. Put the car on the emergency brake and block back wheels. Lift and fix a forward part of the car. Remove the right forward wheel.
6. Remove a mudguard of the right forward wing.
7. Establish a jack under the engine, slightly raise it and remove the right support of the engine.
8. Twist spark plugs.
9. Unscrew two bolts of an arm of a natyazhitel of a driving belt (are specified by shooters) and remove a natyazhitel.
10. Disconnect wires from the sensor of a bent shaft and the temperature sensor.
11. Remove a pulley of a bent shaft.
12. Remove a pulley of the pump of system of hydrostrengthening of a wheel.
13. Unscrew the lower bolts of a cover of a gas-distributing belt (are specified by shooters).
14. Remove a lifting arm of the engine (A) and unscrew three bolts of a cover of a gas-distributing belt (are specified by shooters).
15. After twisting of the remained bolts (are specified by shooters), uncover also laying. Pick up the probe phone for measurement of level of oil.
16. If you are going to reuse a gas-distributing belt, make on it the tag specifying the direction of its rotation.
17. Combine synchronizing tags of an asterisk of a bent shaft and a tag of asterisks of camshafts (see rice. Synchronizing tags of a bent shaft, rice. Synchronizing tags of the camshaft – a forward number of cylinders, rice. Synchronizing tags of the camshaft – a back row of cylinders).
18. Unscrew two bolts of a natyazhitel of a gas-distributing belt (A) and remove a natyazhitel. Weaken a bolt of a pulley of a natyazhitel (In).
19. Take off a gas-distributing belt.
20. If asterisks of camshafts are damaged, then now you can remove them and replace.
21. Remove an asterisk of a bent shaft and replace it if it is damaged.

Check

PERFORMANCE ORDER
1. Examine a gas-distributing belt (see subsection 3.1.8).
2. By means of a vice, squeeze the piston of a natyazhitel so that you could insert a core 1,5 mm thick into the second lower opening of a natyazhitel.
3. Check that intermediate pulleys rotated freely.

Installation

PERFORMANCE ORDER
1. Carefully clean area of installation of a gas-distributing belt in a forward part of the engine.
2. Establish an asterisk of a bent shaft.
3. Temporarily twist a bolt of a pulley of a bent shaft and turn a shaft counterclockwise to combine a tag on an asterisk of a bent shaft with a tag on an engine case.
4. Establish a gas-distributing belt.
5. Establish a natyazhitel (with the compressed piston and with the core inserted into the lower opening) and tighten its bolts.
6. Get a core from an opening of a natyazhitel. Turn a bent shaft on two whole revolutions (720 °). Check whether still synchronizing tags of asterisks (see rice are combined. Synchronizing tags of a bent shaft, rice. Synchronizing tags of the camshaft – a forward number of cylinders, rice. Synchronizing tags of the camshaft – a back row of cylinders).
Prevention

You do not start the engine until you are not absolutely convinced that the gas-distributing belt is established correctly. If the belt is established incorrectly, the engine can sustain serious damage.


7. Tighten a bolt of a pulley of a natyazhitel.
8. Establish the remained details upside-down.
