THE GENERAL DATA

THE PETROL ENGINE

1. A bolt of M 6 х 45, 10 Н.м.
2. A bolt of M 6 х 95, 10 Н.м.
3. A bolt of M 6 х 25, 10 Н.м.
4. A bolt of M 8 х 85, 20 Н.м.
11, 12, 32. Hoses for a cooling liquid
33. A pulley
33а. A bolt, 12 Н.м.
35. A paper sealing lining

Removal

PERFORMANCE ORDER
1. Disassemble hydraulic муфту the fan of system of cooling.
2. Merge cooling liquid in suitable capacity.
3. Remove from the pump of system of liquid cooling 3 hoses for a cooling liquid. Preliminary completely open and shift back clips.
4. Ослабьте, without turning out, bolts on a pulley of the pump of system of liquid cooling.
5. Remove клиновой a ridge belt.
6. Unscrew and remove a pulley of the pump of system of liquid cooling.
7. The 6-cylinder engine: turn out bolts (263/264) on the block of cylinders of the engine and remove the pump of system of liquid cooling.
8. Carefully clear sealing surfaces on the case of the pump and a cover картера the steering mechanism.

Installation

PERFORMANCE ORDER
1. Screw the pump of system of liquid cooling, using a new paper sealing lining.
The prevention

At factory the pump загерметизирован liquid condensing means. At assemblage it is possible to apply a paper sealing lining or liquid condensing means, for example, Loctite. Thus sealing surfaces on the pump of system of liquid cooling grease with condensing means in regular intervals and, whenever possible, a thin layer.


2. Screw a pulley of the pump of liquid cooling.
3. Put on клиновой a ridge belt.
4. Tighten to the full bolts on a pulley of the pump of liquid cooling.
5. Spread all hoses for giving of a cooling liquid and fix their clips.
6. Establish hydraulic муфту the fan of system of cooling.
7. Fill in cooling liquid.

THE DIESEL ENGINE IN VOLUME OF 2,0 L

2. A bolt, 10 Н.м.
At presence at a bolt internal торсионной the inhaling moment makes heads 15 Н.м.
3. A hose of a cooling liquid
4. A hose of system of heating
5. A pulley
6. The pump of system of liquid cooling
7. A drain line
8. A bolt
9. Directing plugs
10. Consolidation
11. The case of the pump of system of liquid cooling
12. Directing plugs
13. A bolt, 25 Н.м.
14. Consolidation
15. The generator
16. A generator rack
17. A sealing ring
18. Рециркуляционный the fuel pipeline

Removal

PERFORMANCE ORDER
1. Disconnect from the storage battery a weight wire (–).
The prevention

The anticreeping code of radio is thus erased.


2. Remove hydraulic муфту the fan of system of cooling.
3. Merge cooling liquid in pure capacity.
4. Ослабьте, without unscrewing, bolts of a pulley of the pump of system.
5. Remove клиновой a ridge belt.
6. Unscrew and take a pulley of the pump of system of liquid cooling.
7. Remove from the pump hoses (3) and (4) for giving of a cooling liquid. Preliminary completely open collars and shift them back.
8. Remove the generator.
9. Unscrew a generator rack.
10. Unscrew the case of the pump of system of liquid cooling and remove it together with the pump. At case removal remove рециркуляционный the fuel pipeline.
11. Unscrew and extend the pump of system of liquid cooling.
12. Carefully clear sealing surfaces of the pump of system of liquid cooling, its case and the block of cylinders of the engine.

Installation

PERFORMANCE ORDER
1. Screw the pump of system of liquid cooling with a new paper lining with the moment 10 Н.м.
2. Screw the case of the pump of system of liquid cooling with a new paper lining with the moment 10 Н.м. Thus spread рециркуляционный the fuel pipeline, preliminary moisten a sealing ring with a cooling liquid, do not apply some oil.
3. Screw a rack of the generator with the moment 25 Н.м.
4. Establish the generator.
5. Spread all hoses for giving of a cooling liquid and fix their collars.
6. Screw a pulley of the pump of system of liquid cooling.
7. Establish клиновой a ridge belt.
8. Screw up a pulley of the pump of system of liquid cooling with the moment 10 Н.м. And, accordingly, with the moment 15 Н.м. In case of bolts with internal торсионной a head.
9. Establish hydraulic муфту the fan.
10. Fill in cooling liquid.
11. Attach to the plug of the storage battery a weight wire.
12. Expose time for hours.
13. Enter an anticreeping code of radio.
