Carburetor dismantling

 Removal of conclusions of the socket from the case

1, 6. FBSV valve conclusions

2. Socket

3. Limiter

4. Screw-driver

5. Conclusions

PERFORMANCE ORDER
1. Remove the carburetor.
2. Remove butterfly valve springs.
3. Remove a hose of cooling liquid and a butterfly valve spring.
4. Remove the pneumoshock-absorber – drawing at the left (on and/m from a manual transmission) or the electropneumovalve (on and/m from an automatic transmission), having unhooked a rod.
5. On and/m from an automatic transmission unscrew screws, remove a drive of the proof-reader of idling and take aside (the proof-reader tension from the battery is forbidden to check).
6. Remove a socket arm.
7. Disconnect a vacuum hose of an air zaslonka.
8. Unscrew 5 screws and uncover the poplavkovy chamber, slightly it having hooked.
9. Remove a float, get the needle valve and turn out a saddle.
10. A tiny screw-driver disconnect conclusions of the electromagnetic feedback-valve (FBSV valve).
11. Remove a cover, unscrew the screw (1) and remove the FBSV valve (2 – conclusions).
12. Remove the holder and get the electromagnetic gate-type valve (SCSV valve), without disconnecting wires.
13. A tiny screw-driver disconnect plugs of wires from the SCSV valve and remove it.
14. Remove heads of rivets and uncover a breaker of an air zaslonka. Unscrew the small screw in the lower part of a cover.
15. Remove laying, a bimetallic element and a plate.
16. Carefully remove the remains of rivets.
17. Disconnect from the socket a conclusion of a bimetallic element.
18. Remove the ventilating valve, having paid attention to an arrangement of small springs of the valve.
19. Uncover a drive of an air zaslonka (shooters specified screws of fastening of an air zaslonka).
20. Get a counterbalance and the ball valve of the locking valve.
21. Disconnect draft of the accelerating pump from the butterfly valve lever.
22. Carefully turn out the screw from the butterfly valve case. Turn out the main jet.
23. Unscrew screws and get details of the accelerating pump from the case.
24. Unscrew 3 screws on a cover of an ekonomayzer and uncover, a spring and a diaphragm.
25. Disconnect a vacuum hose of the chamber of depression, disconnect a rod, unscrew bolts and remove the chamber.
26. Remove the sensor of turn of a butterfly valve (it is specified by an arrow).
27. Wash out carburetor channels solvent and blow the compressed air.
28. Check a condition of diaphragms, a float and the needle valve, freedom of moving of rods, drafts and levers. Check operation of solenoidal valves and resistance of their windings (the FBSV valve – 48–60 Ohm, the SCSV valve – 54–66 Ohm, a bimetallic element – 6 Ohm at 20 ° C).
29. Check the pneumoshock-absorber, having pulled for a rod, – resistance thus should be felt, at an otpuskaniye the rod quickly comes back back.
30. Press a rod of the chamber of depression and release, having closed a finger an opening for an air suction, – the rod should remain motionless.

Assembly

 Check of opening of an air zaslonka at completely open butterfly valve

1. Air zaslonka

2. Gap

3. The lever for adjustment

PERFORMANCE ORDER
1. Establish the sensor of turn of a zaslonka, the depression chamber, collect and establish an ekonomayzer, the accelerating pump. Establish the locking valve, a cover of a breaker of a drive of an air zaslonka, the ventilating valve. Wrap the main jets.
2. Collect the socket of a bimetallic element. Establish an element upside-down, having replaced laying and having combined labels. A cover fix rivets, to use screws it is not recommended.
3. Collect FBSV-sockets and SCSV valves. Establish valves and collect the case of a zaslonka and the diffuzor case, having replaced a sealant and having screwed the screw.
4. Establish all details on a cover of the poplavkovy chamber. Adjust the provision of a float.
5. Establish a cover of the poplavkovy chamber, fix 5 screws. Establish a socket arm, the pneumoshock-absorber (or the pneumovalve), all springs, levers and drafts. Check smoothness of moving of drafts.
6. Check a gap between a butterfly valve and a diffuzor wall, having laid a drill and having transferred an idling cam to extreme top situation. The gap should be 0,63 mm on the engine of 2,0 l (from a manual transmission), 0,71 mm on engines of 2,0 l (from an automatic transmission), 0,71 mm on engines of 2,6 l (from a manual transmission), 0,80 mm on engines of 2,6 l (from an automatic transmission).
7. Check a gap between an air zaslonka and a chamber wall at completely open butterfly valve. For this purpose a finger close an air zaslonka and the lever open a butterfly valve. The gap should be 2 mm. If necessary adjust a podgibaniye a rychazhka.

Prevention

This gap after dismantling assembly should not change and as a rule only is checked. The wrong adjustment of a gap very strongly worsens road performance of the car at not heated-up engine.


8. Replace laying and establish the carburetor (see subsection 8.1.2.1).
