3.2.2.24. A gear belt and the tension mechanism
THE GENERAL DATA

The tension mechanism

Adjusting labels of asterisks of a camshaft and ТНВД

ENGINES 4ZD1 AND 4ZE1

Gear belt and the tension mechanism (engines 4ZD1 and 4ZE1)

1 – a bolt of a pulley of a cranked shaft
2 – covers
3 – a gear belt
4 – a roller натяжителя and a spring
5 – a leading asterisk of a cranked shaft
6 – a camshaft asterisk
7 – a camshaft nave
8 – the oil pump with a drive asterisk
9 – the pump of a cooling liquid
10 – back covers of a gear belt

Removal

PERFORMANCE ORDER
1. Disconnect the battery from weight, remove a pulley of a cranked shaft.
2. Remove the top and bottom covers of a gear belt.
3. Turn a cranked shaft so that the label on a camshaft asterisk was combined with a label on a back cover of a gear belt, and шпонка on a cranked shaft was combined with a label on the holder of a forward epiploon. When the specified labels the piston of 4th cylinder are combined is in ВМТ a compression step.
4. Ослабьте a tension of a gear belt, remove a belt from a camshaft asterisk.

Installation

Label combination on a camshaft asterisk (engines 4ZD1 and 4ZE1)

Label combination on an asterisk of a cranked shaft (engines 4ZD1 and 4ZE1)


PERFORMANCE ORDER
1. Without breaking combination of labels of asterisks of a cranked shaft and a camshaft, establish a belt. A belt to establish in a following order: an asterisk of a cranked shaft, an asterisk of the oil pump, a camshaft asterisk.
2. Result a roller натяжителя in contact with a belt.
3. Turn a cranked shaft on 2 complete revolutions in a direction opposite to normal rotation and again combine adjusting labels.
4. Release a roller bolt натяжителя to provide demanded effort to a belt from outside springs. Tighten a roller bolt натяжителя with the moment 20 Н.м.
5. Establish both covers and a pulley of a cranked shaft.
6. Connect the battery to weight. Start the engine, be convinced of absence of a leak.

DIESEL ENGINES S223 AND С223Т

Adjusting labels ТНВД on diesel engines С223

Removal of a clamp of a gear belt on diesel engines С223

Sequence of an inhaling of bolts of the mechanism of a tension of a belt on diesel engines С223

Removal

PERFORMANCE ORDER
1. Disconnect the battery from weight, merge cooling liquid.
2. Uncover a gear belt. Remove a flange of an asterisk of drive ТНВД.
3. Disconnect a spring from натяжителя a gear belt.
The prevention

At removal of a spring do not put too big effort, spring breakage otherwise is possible.


4. Turn away a roller bolt натяжителя and remove a roller.
5. Remove a gear belt.

Installation

PERFORMANCE ORDER
1. Expose the piston of 1st cylinder in ВМТ a compression step.
2. Combine adjusting labels on asterisk ТНВД and on a camshaft asterisk so that these labels settled down the friend opposite to the friend.
3. Put on a new belt in the following sequence: an asterisk of a cranked shaft, a camshaft asterisk, asterisk ТНВД. Between asterisks of a camshaft and ТНВД there should be a weak point.
4. Establish натяжитель and a roller натяжителя so that the edge натяжителя was opposite to pins on a roller cover натяжителя.
5. Tighten a roller nut by hand, the roller should rotate freely.
6. Establish a spring натяжителя, tighten a nut, but not to the full (with the moment 30–48 Н.м.).
7. Turn a cranked shaft on 2 complete revolutions clockwise, thus the belt takes seat in a place. Then tighten a cranked shaft on 90 to expose ТНВД.
8. Ослабьте a belt tension for what release a roller nut натяжителя. Tighten a nut with the moment 108–128 Н.м.
9. Establish a flange of asterisk ТНВД so that the aperture on the brink of a flange has coincided with a triangular label on a drive asterisk.
10. Turn a cranked shaft on 2 complete revolutions clockwise and establish the piston of 1st cylinder in ВМТ a compression step. Be convinced that the triangular label on an asterisk has coincided with deepening in a flange then check up a tension of a belt which should be 1,3–2,2 кГс.
11. Establish a cover of a gear belt.
12. Connect the battery to weight.
