THE GENERAL DATA

Bolts of fastening of a casing of a belt

Removal of the tension device of a gear belt by means of a key 21.012

1 – the tension device,

2 – a spring,

3 – an adjusting bolt,

4 – a roller of the tension device.

Adjusting signs on system timing

 

Removal

PERFORMANCE ORDER
1. To establish a transmission in neutral position and to fix the car a lay brake.
2. To remove клиновой a belt for what to weaken bolts, крепящие the generator and to shift it towards the engine.
3. To establish the piston of 1 cylinder in the top dead point, turning a cranked shaft for a bolt, крепящий a pulley клинового a belt, in a direction of working rotation until the label of the top dead point will not be combined with a label on a casing.
4. To unscrew bolts, крепящие a casing of a gear belt, to reject aside and forward and to remove it.
5. To weaken a tension of a gear belt, in the beginning having unscrewed a bolt with internal шестигранником (a key s=6) on the block of a tension of a belt, and then a bolt with шестигранной a head (s=16) and overcoming resistance of a spring, to incline the block of a tension and полнлстью to turn away bolts.
6. To remove a pulley of a belt from a cranked shaft. If the gear belt acts in film only from a cam-shaft pulley to remove a pulley from a cranked shaft does not follow.
7. Cнять a gear belt.

The prevention

To turn the engine it is impossible for a cam-shaft pulley as it can destroy a belt. At presence on a belt of cracks, traces of oil or пореждений teeths, it is necessary to replace a belt.
That belt by means of a key 21.012.



Installation

PERFORMANCE ORDER
1. To check up coincidence of labels on a pulley of a cam-shaft and a head бдока cylinders. If necessary to combine labels.
2. An intermediate shaft to establish so that the label on a distributor rotor was over меткою on the brink of the distributor. It is preliminary necessary to uncover the distributor having raised a screw-driver 2 lateral fixing скобы and having unscrewed 2 screws of fastening of a cover.
3. To establish a gear belt on a pulley of a cranked shaft and to tighten on cranked to a shaft a pulley клинового a belt.
4. To establish a gear belt on a pulley of a cam-shaft and to weaken the block of a tension of a belt.
5. To turn on two turns a cranked shaft for a pulley клинового a belt so that the tension block became on a gear belt and to tighten the tension block: at first a bolt with шестигранной a head, and then with internal шестигранником.
6. To turn a cranked shaft on 2 turns and to check up conformity of labels on a pulley of a cam-shaft, a rotor of the distributor of ignition and a pulley клинового a belt of a cranked shaft.
7. To establish a casing of a gear belt.
8. To establish a cover of the distributor of ignition (fig. Adjusting signs on system timing see).
