8.1.8. Inlet gas pipeline

GENERAL INFORMATION

4-CYLINDER PETROL ENGINE

Removal

PERFORMANCE ORDER
1. Remove a cross-section pipe of the air filter.
2. Disconnect from the plug of the storage battery a weight wire (–).
Prevention

The anticreeping code of radio is thus erased.


3. Disassemble the fuel distributor with klapanny nozzles.
4. Unscrew a well with wires.
5. Unscrew and put aside a vessel of a stekloomyvatel.
6. Separate shtekkerny connection (shooter) to executive body of system of regulation of frequency of rotation of a shaft of the engine idling. For this purpose open a collar of fastening and Take from a spring clip a wire.
7. Unscrew a rack of the inlet gas pipeline (19/4).
8. Separate shtekkerny connection of the engine/coil of ignition. Unscrew ignition coils.
9. Remove the line (77/2) going to the regeneration valve.
10. Unscrew the pipeline (23) which was under depression going to the amplifier of a brake drive.
11. Remove and mark a sticky tape all pipelines on the inlet gas pipeline being under depression.
12. Unscrew on the inlet gas pipeline a bolt (15/1) from a rack of the pump of strengthening of a steering drive.
13. Remove directing detail (30/5). Thus at first Take from it a plastic nipple.
14. Unhook a cable of management of gas (30). For this purpose enter through a cut in the kulisny lever (32/6) a hummock drive. Compress a plastic spring clip (30/4) and extend on a support Bowden's (32/3) cable (a steel wire in a flexible twisted cover).
15. Automatic transmission: unhook Bowden's regulating operating pressure the cable.
16. Tempomat: unhook connecting draft.
17. Unscrew bolts (19/1) and nuts (19/2).
18. Take the inlet gas pipeline.

Installation

PERFORMANCE ORDER
1. Clear sealing surfaces and check them a ruler on lack of curvatures.
2. Screw the inlet gas pipeline with new consolidation (19/3). Alternately hardly tighten bolts with the moment of 20 N of m (rough value).
3. Tempomat: hang connecting draft.
4. Automatic transmission: hang Bowden's regulating operating pressure the cable, and adjust this cable.
5. Enter a cable of management of gas through an opening in a support, press it into a support and fix.
6. Hang together with a directing detail a cable of management of gas. Pay attention to that the plastic nipple was fixed in a directing detail.
7. Weaken a rack of the pump of strengthening of a steering drive, then insert a bolt (15/1) to the inlet gas pipeline and twist it. Hardly tighten a rack of the pump of strengthening of a steering drive.
8. According to the marking made earlier get on the inlet gas pipeline all pipelines being under depression.
9. Screw the pipeline which was under depression of the amplifier of a brake drive.
10. Get the pipeline (77/2) going to the regeneration valve.
11. Establish ignition coils.
12. Screw a rack of the inlet gas pipeline.
13. Connect electric wires to executive body of system of regulation of frequency of rotation of a shaft of the engine idling. Fix a collar and fix wires in a spring clip.
14. Establish and screw a vessel of a stekloomyvatel.
15. Screw a well with wires.
16. Establish the fuel distributor together with klapanny nozzles.
17. Mount a cross-section pipe of the air filter.
18. Adjust a cable of management of gas.
19. Attach to the plug of the storage battery a weight wire (–). Establish time on hours. 38. Enter an anticreeping code of radio.
20. Start the engine and check tightness of all connections.
21. Check idling system (work for a repair truck).

3. Automatic transmission: on the block of regulation unhook Bowden's cable for regulation of operating pressure.
4. Unhook connecting draft of the valve of regulation of pressure (200).
5. Unhook connecting draft (204) pumps of nozzles.
6. Unhook a plastic spring clip from a gas (228) cable.
7. Unscrew 4 bolts (205) and take aside adjusting draft.
8. Unscrew on the vacuum pump the vacuum pipeline.
9. Dismantle the ventilating line of the engine (107).
10. Unhook fixing clips (54/1) топливопровода a high pressure on the inlet gas pipeline.
11. Unscrew bolts (109) at the left and on the right on the holder of the inlet gas pipeline.
12. Unscrew bolts (108).
13. Unscrew the inlet gas pipeline.

Installation

PERFORMANCE ORDER
1. Clear sealing surfaces and check them on planeness by means of a ruler and measuring щупа.
2. Screw the inlet gas pipeline with new sealing rings of round section. Alternately tighten bolts with the moment of 25 N of m (rough value).
3. Screw the holder for the inlet gas pipeline.
4. Take on spring clips топливопровод a high pressure.
5. Establish the ventilating line of the engine.
6. Screw on the vacuum pump the vacuum pipeline.
7. Screw adjusting draft.
8. Screw on the inlet gas pipeline plastic spring clips.
9. Hang connecting draft of the pump of nozzles.
10. Hang connecting draft of gas.
11. Automatic transmission: hang and adjust Bowden's cable for regulation of operating pressure.
12. Establish a cross-section pipe of the air filter.
