GENERAL INFORMATION

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 opening in the lever of the mechanism of a tension of a gear belt, turn the lever clockwise against the stop and fix in this situation, inserting a core into the corresponding opening in a basic plate of the mechanism of a tension. Leave the tension mechanism in this situation before installation of a new belt. unscrew bolts of fastening of a wheel and remove a wheel.
6. Check correctness of combination of labels on pulleys of cranked and distributive shaft.
7. Weaken 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 the direction of its movement.

Prevention

After removal of a belt it is strictly 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 a gear belt on existence of non-uniform wear, 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, it is necessary to find a source of leakage of oil and to eliminate it.

Installation

PERFORMANCE ORDER
1. Check and clear pulleys of a drive of a gear belt. Also check a condition and freedom of rotation of a pulley of the mechanism of a tension. Check, that adjusting labels on pulleys were 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 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 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 the normal direction of rotation.
7. Check 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 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.
