5.1.13. The throttle case Removal and installation

ENGINES SOCH OF 1,6 L

PERFORMANCE ORDER
1. Remove pressure in fuel system and disconnect the negative plug from the accumulator.
2. Loosen the a collar also disconnect a tube of an air inlet from a cover of the case of a throttle. Disconnect hoses from a cover.
3. Unscrew screws of fastening of a cover of the case of a throttle.
4. Uncover also a sealing ring the top part of the case of a throttle.
5. Release clamps and disconnect electric sockets from a potentiometer of a throttle and the step-by-step engine operating turns of idling.
6. Remove a hose of giving of fuel from a lateral part of the case of a throttle.
7. Disconnect draught of an accelerator from spherical шарнирного connections on the throttle case.
8. Disconnect vacuum hoses and ventilation hoses картера the engine from the throttle case.
9. Unscrew nuts, fastening the throttle case to an inlet collector, and remove the throttle case together with a lining (on a photo – engine SOCH 1,6).

10. Unscrew screws and remove the top section of the case of a throttle.
11. Check up that interfaced surfaces of section of the case of a throttle pure and dry, establish a new lining, establish the top section of the case of a throttle and fix screws. Before installation of screws put on a carving of screws the means interfering their unscrewing.
12. Check up that interfaced surfaces of the case of a throttle both an inlet collector pure and dry, establish a new lining and establish the throttle case on a collector. On a carving of nuts of fastening of the case of a throttle put the means interfering their unscrewing, both gradually and consistently screw up nuts the demanded moment.
13. Connect hoses and draught of an accelerator.
14. Connect a hose of giving of fuel to the throttle case, tightening a nut the demanded moment. Connect electric sockets.
15. Establish a sealing lining on the top casing of the case of a throttle, establish a casing into place and fix screws. Connect the inlet air channel and vacuum hoses.
16. Connect the accumulator.

ENGINES DOCH OF 1,6 L

PERFORMANCE ORDER
1. Remove pressure in fuel system and remove the negative plug from the accumulator.
2. Uncover a jellied mouth of engine oil, unscrew screws and remove a protective casing. Establish a stopper into place.
3. Unscrew bolts (are specified by arrows) and remove a plastic arm of a plait of wires from a back part of an inlet collector.
4. Disconnect electric sockets (are specified by arrows) from the gauge of oxygen, the block of ignition, the valve of clearing and other sockets on a collector left-hand side.
5. Unscrew nuts of fastening of the tyre of grounding to a head of the block of cylinders and a collector and move a plastic arm aside from a collector.
6. Remove the ignition block.
7. Remove the valve of clearing from the left forward end of a collector and disconnect a hose of the valve from a collector.
8. Remove a hose of the vacuum amplifier of brakes (1) from an inlet collector. Remove a ventilation hose картера the engine (2) which union is located near to the union of a hose of the vacuum amplifier of brakes.
9. Loosen the a collar also remove the inlet air channel from the case of throttles.
10. Unscrew bolts of fastening of an arm of a cable of an accelerator to a collector. Remove скобу and take a cable of an accelerator from a cam of a throttle and move it aside.
11. Unscrew bolts and remove the case of throttles from an inlet collector.
12. Loosen the connecting nuts also disconnect fuel hoses from a fuel highway.
13. Turn throttle cases, ослабьте collars and remove hoses of giving of a cooling liquid from the case of throttles.
14. Disconnect electric sockets from a potentiometer of a throttle and the step-by-step engine of management of idling turns then take the case of throttles from a motor compartment.
15. Installation is made in sequence, return to removal. Thus it is necessary to adjust an accelerator cable.

ENGINES OF 1,8 AND 2,0 L

PERFORMANCE ORDER
1. Remove a wire of weight from the accumulator.
2. Disconnect electric sockets from the gauge of temperature of air arriving in the engine and a measuring instrument of a stream of air.
3. Loosen the a collar also remove a ventilation hose картера the engine from a back part of a cover of a head of the block of cylinders.
4. Loosen the collars also remove the inlet air channel from the air filter and the case of throttles.
5. Remove скобу fastenings and separate a cable of an accelerator from spherical шарнирного connections of a cam of a throttle.
6. Unscrew bolts and remove an arm of a cable of an accelerator from the case of throttles.
7. Press hoses of giving of a cooling liquid to a back part of the case of throttles, ослабьте collars and remove both hoses.
8. Remove electric sockets from a potentiometer of a throttle and the spherical engine of management of idling turns.
9. Note an arrangement and disconnect hoses from the case of throttles, then unscrew nuts and remove the case of throttles from an inlet collector.
10. Installation is made in sequence, return to removal, thus it is necessary to adjust an accelerator cable.
