Removal

PERFORMANCE ORDER
1. To install the transmission in neutral situation and to fix the car the parking brake.
2. To take off maple a belt for what to weaken the bolts fixing the generator and to shift it towards the engine.
3. To install the piston of 1 cylinder in the top dead point, turning a bent shaft for a bolt, the fixing pulley of a maple belt, in the direction of working rotation until the tag of the top dead point is not combined with a tag on a casing.
4. To unscrew the bolts fixing 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 an internal hexagon (s=6 key) on the belt tension block, and then a bolt with a six-sided head (s=16) and overcoming spring resistance, to incline the block of a tension and полнлстью to turn off bolts.
6. To remove a belt pulley from a bent shaft. If the gear belt is removed only from a cam-shaft pulley, then it is not necessary to remove a pulley from a bent shaft.
7. To take off a gear belt.

Prevention

It is impossible to turn the engine for a cam-shaft pulley as it can destroy a belt. In the presence on a belt of cracks, traces of oil or porezhdeniye of teeths, the belt needs to be replaced.
that belt by means of a key 21.012.



Installation

PERFORMANCE ORDER
1. To check coincidence of tags on a pulley of a cam-shaft and a head of a bdok of cylinders. If necessary to combine tags.
2. To establish an intermediate shaft so that the tag on a rotor of the distributor was over a tag on the edge of the distributor. It is previously necessary to uncover the distributor having raised the screw-driver 2 side fixing brackets and having unscrewed 2 screws of fastening of a cover.
3. To establish a gear belt on a pulley of a bent shaft and to tighten on cranked to a shaft a pulley of a maple belt.
4. To establish a gear belt on a pulley of a cam-shaft and to weaken the belt tension block.
5. To turn on two turns a bent shaft for a pulley of a maple belt so that the block of a tension became on a gear belt and to tighten the tension block: at first a bolt with a six-sided head, and then with an internal hexagon.
6. To turn a bent shaft on 2 turns and to check compliance of tags on a pulley of a cam-shaft, a rotor of the distributor of ignition and a pulley of a maple belt of a bent shaft.
7. To establish a casing of a gear belt.
8. To establish an ignition distributor cover (see rice. Adjusting signs of system of gas distribution).
