CAM-SHAFT DRIVE

Removal

PERFORMANCE ORDER
1. Disconnect a cable of weight from the battery.

The prevention

As a result of it electronic memory, for example, a radio receiver code is erased. Before battery switching-off it is necessary to read instructions in subsection 7.2.


2. Unscrew a cover of a head of cylinders.
3. Establish the piston of 1st cylinder in position ВМТ.
4. For this purpose establish a transmission on a neutral and tighten a manual brake.
5. Turn коленвал for the central bolt in a direction of rotation of the engine (clockwise) that the notch on a belt pulley коленвала was opposite to an arrow on the engine block.
6. At the same time the cam-shaft should stand so that cams of 1st cylinder have been turned upwards.
7. Otherwise turn коленвал on 1 turn forward in a direction of rotation of the engine.
8. The second possibility of rotation коленвала: lift a forward part of the car on the one hand, include 5th transfer and turn a wheel a hand.
9. Lift the engine a jack with a lining to release a forward support of the engine.
10. Unscrew the forward built in console of the engine.
11. Remove клиновой a generator belt.
12. If is, remove клиновой a belt сервонасоса and the conditioner compressor.

The prevention

After the engine will be established in position ВМТ, whether muffle transfer and once again check up on a belt pulley коленвала the label coincides with an arrow on the engine block, if necessary modify. If labels coincide, at all do not change engine installation.


13. Unscrew ременный a pulley of the water pump.
14. Block the engine and unscrew a bolt of fastening of a belt pulley коленвала.
15. For engine blocking include 5th transfer and ask the assistant to press a brake pedal.
16. Remove a pulley коленвала a usual stripper.

The prevention

Stripper hooks should be hooked only for an underside of a belt pulley.


17. Remove the top and bottom casing of a gear belt.
18. If the old belt it is necessary to mark it is used again. On a belt it is necessary to put the arrow a felt-tip pen specifying a direction of rotation. The engine rotates clockwise.
19. Turn a bolt of a tension roller by means of a key under internal шестигранник – a direction of an arrow (1), and a tension roller by means of the second key (2) counter-clockwise while the gear belt will not be weakened. Tighten back a bolt of a tension roller.
20. Unscrew a lateral plate from a cam-shaft gear wheel.
21. Unscrew an intermediate roller.
22. Remove a gear belt with a gear wheel коленвала.

The prevention

Do not change more position ВМТ of distributive and cranked shaft. If it is necessary turn a cam-shaft at the removed gear belt, watch, that коленвал was not in position ВМТ (differently there is a danger of damage of valves and pistons). For this purpose mark gear wheel position коленвала (put a colour label on a gear wheel коленвала and on the block of cylinders). Then turn a gear wheel коленвала on 1/4 turns (90 ) forward or back.


Installation

PERFORMANCE ORDER
1. Check up a condition of a gear belt.
2. Check up натяжитель a belt on a rust, damages and ease of a course.
3. If has been removed, establish a lateral plate of a gear wheel коленвала that the oblique part has been turned to the engine.
4. Be convinced that distributive and cranked shaft are in position ВМТ of the piston of 1st cylinder. Segment шпонка коленвала in position ВМТ specifies vertically upwards.
5. Screw an intermediate roller with effort 40 Н.м.
6. Establish a gear belt with a gear wheel коленвала. Thus consider the label of a direction of rotation put at removal. The belt which was in the use should rotate only in the same party, as earlier.
7. Tighten ременный a pulley коленвала with effort 150 Н.м.
8. For deduction include 5th transfer and ask the assistant to press a brake pedal.
9. Combine a white stroke on a gear belt with a label on a gear wheel of a cam-shaft and коленвала (). Labels () on a gear belt will defend on 43 teeth (size).
10. The arrow on a gear belt should specify towards a casing.
11. Screw a lateral plate of a gear wheel of a cam-shaft with effort 7 Н.м. Preliminary cover bolts with protective means "Loctite".
12. Ослабьте tightening a bolt натяжителя a belt that натяжитель has pressed a belt.
13. Turn коленвал on 2 turns clockwise, thus натяжитель will give to a belt a correct tension.
14. Before the termination of 2nd turn, insert flat щуп (1) from above, an arrow between a gear belt (3) and an intermediate gear wheel (2). The sizes щупа: width – 12,5 mm, length – 150 mm, a thickness – 0,3 mm.
15. Tighten tightening the screw of a tension roller with effort 40 Н.м, thus keeping a roller from проворачивания a key, the belt tension differently can decrease.
16. Once again check up position ВМТ of distributive and cranked shaft. All labels ВМТ at the tense, gear belt should coincide simultaneously, if necessary repeat adjustment.
17. Turn коленвал counter-clockwise a little and pull out щуп.
18. Screw the bottom and top casing with effort 5 Н.м.
19. Screw a pulley коленвала for the central bolt with effort 120 Н.м.
20. For fixing коленвала include 5th transfer and ask the assistant to press a brake pedal.
21. Screw ременный a pulley of the pump of system of cooling with effort 10 Н.м.
22. Establish клиновый a belt.
23. Screw a cover of a head of cylinders.
24. Screw a belt pulley of the pump of system of cooling.
25. Screw the forward built in console of the engine.
26. Attach a cable of weight of the battery.

DRIVE ТНВД

Removal

PERFORMANCE ORDER
1. Establish the piston of the cylinder 1 in position ВМТ.
2. Remove the air channel with the air filter.
3. Unscrew a casing of a gear belt.
4. Ослабьте a nut of a tension roller bent накидным a key also wring out a tension roller a screw-driver in an arrow direction while the gear belt will not be weakened.
5. Tighten back a nut of a tension roller.

The prevention

For protection of a tension roller wrap up a screw-driver a matter.


6. Remove a belt.

The prevention

Do not change at the removed gear belt position ВМТ of a camshaft and gear wheel ТНВД.


Installation

PERFORMANCE ORDER
1. Check up a condition of a gear belt.
2. Check up натяжитель a belt on a rust, damages and ease of a course.
3. Be convinced that a cam-shaft and ТНВД are in position ВМТ of the piston of 1st cylinder.
4. Establish a gear belt.
5. Combine white strokes on a belt with labels on a gear wheel of a cam-shaft and gear wheel ТНВД (). Labels () on a belt will defend on distance And – 23 teeth.
6. The arrow on a gear belt should be turned towards a casing.
7. Ослабьте a tightening nut of a tension roller that натяжитель has pressed on a belt.
8. Turn коленвал on 2 turns clockwise, thus натяжитель will give to a gear belt a correct tension.

The prevention

Do not turn the engine for a cam-shaft gear wheel, gear belts differently will be overloaded.


9. Tighten a tightening nut of a tension roller with effort 20 Н.м, thus keep a tension roller a screw-driver, differently the tension of a gear belt can decrease.
10. Once again check up installation ВМТ of a cam-shaft and ТНВД. All labels ВМТ at the tense gear belt should coincide simultaneously, if necessary repeat adjustment.
11. Screw a casing of a gear belt with effort 5 Н.м.
12. Establish the air channel with the air filter.
