Remove a forward cover 1 (see fig. 2.8) a gear belt. Turn off a nut of fastening of the mechanism of a tension. Weaken and take off a gear belt. Shoot a tension video 7 with a remote washer 6. Holding a pulley 4 camshafts from a provorachivaniye with adaptation 67.7811.9509, turn off a bolt of fastening of a pulley, remove a pulley and a spline. Remove the cogged pulley 5 from a bent shaft.

Fig. 2.9. Removal of a receiver and inlet pipe: 1 – the supporting arm; 2 – inlet pipe; 3 – laying of a receiver; 4 – receiver; 5 – an arm for an accelerator drive cable tip; 6 – arm; 7 – screen of a final collector; 8 – basic arm

Turn off bolts of fastening of the pump 2 (see fig. 2.9) cooling liquid. Turn off a bolt and a nut of fastening of a back cover of 1 gear belt and remove it. Take out from a nest in the block of cylinders the pump of cooling liquid with laying 3.

Fig. 9.7. Removal of an inlet pipe and final collector: 1 – sensor of a control lamp of pressure of oil; 2 – inlet pipe; 3 – zabornik of warm air; 4 – an arm of the bringing pipe of the pump of cooling liquid; 5 – final collector; 6 – laying

Remove an inlet pipe 2 (fig. 9.7) and a final collector 5 with laying 6, a zabornik 3 warm air and an arm 4. Turn out the sensor of 1 control lamp of pressure of oil from a head of cylinders.

       NOTE
If full dismantling of the engine is not required, then it is possible to remove a head of cylinders assembled with pipelines and auxiliary units.

Fig. 9.8. Removal of knots of the cooling system: 1 – sensor of the index of temperature of cooling liquid; 2 – the taking-away branch pipe of the cooling shirt; 3 – a liquid supply hose from a heater; 4 – a hose of removal of liquid to a heater; 5 – the bringing pipe of the pump of cooling liquid; 6 – thermostat

Remove hoses of 3 and 4 (fig. 9.8) of a supply and removal of cooling liquid to a heater. Disconnect hoses from the thermostat 6 and remove it. Remove the bringing pipe 5 of the pump of cooling liquid and the taking-away branch pipe 2 with laying.
Key 67.7812.9514 turn out the sensor of 1 index of temperature of cooling liquid and a spark plug.
Further dismantling of the engine continues in the order described in section 2.
