THE GENERAL DATA

The prevention

Replacement of a gear belt is necessary for making on the cold engine.


Removal

Installation site of a thin steel core in the mechanism of a tension of a gear belt


PERFORMANCE ORDER
1. Remove the top casing of a gear belt.
2. Establish the piston of the first cylinder in the top dead point in a compression step.
3. Remove a pulley of a cranked shaft.
4. Unscrew bolts and remove the bottom casing of a gear belt.
5. Insert a thin steel core into an aperture in the lever of the mechanism of a tension of a gear belt, turn the lever clockwise against the stop and fix in this position, inserting a core into a corresponding aperture in a basic plate of the mechanism of a tension. Leave the tension mechanism in this position before installation of a new belt. Unscrew bolts of fastening of a wheel and remove a wheel.
6. Check up correctness of combination of labels on pulleys of cranked and distributive shaft.
7. Loosen the bolts of fastening of the water pump.
8. Turn the pump so that to reduce a tension of a gear belt.
9. Remove a gear belt from pulleys. For repeated installation of a gear belt note a direction of its movement.

The prevention

After belt removal categorically it is forbidden to turn pulleys of cranked and distributive shaft as there can be an impact of pistons about opened the valve that will lead to serious damage of the engine.


10. Check up a gear belt on presence of non-uniform deterioration, stratification or pollution by oil. Special attention turn on a condition at the basis of teeths of a belt. If on a belt oil traces are found out, it is necessary to find a source of leak of oil and to eliminate it.

Installation

PERFORMANCE ORDER
1. Check up and clear pulleys of a drive of a gear belt. Also check up a condition and freedom of rotation of a pulley of the mechanism of a tension. Check up, that adjusting labels on pulleys have been combined with indexes on the engine.
2. Establish a gear belt on a pulley of a cranked shaft and a camshaft pulley. Thus the forward branch of a belt should be hardly tense. Then establish a belt on a pulley of the pump of system of cooling and a pulley of the mechanism of a tension. Check up that adjusting labels of pulleys are combined with indexes.
3. Take a steel core from the lever of the mechanism of a tension to release a spring of the mechanism of a tension.
4. Repeatedly check up combination of adjusting labels of pulleys with indexes.
5. Pull a gear belt, rotating the water pump until movement of the lever of the mechanism of a tension is observed. Move the pump until the lever of the mechanism of a tension (1) will not be established against an emphasis (2). Then tighten bolts of fastening of the water pump.
6. Temporarily establish a bolt of fastening of a pulley of a cranked shaft and turn a cranked shaft on two complete revolutions in a normal direction of rotation.
7. Check up that adjusting labels on pulleys of distributive and cranked shaft are combined with indexes. Once again turn a cranked shaft on two complete revolutions and check up combination of labels and position of the lever of the mechanism of a tension of a gear belt.
8. If the index of the lever of the mechanism of a tension is not combined with an emphasis, repeat procedure of a tension of a gear belt.
9. Establish casings of a gear belt and a pulley of a cranked shaft.
