3.1.3.2. Adjustment of level of fuel in the float-operated camera

ENGINES OF MODELS 2106, 331 AND 3317 WITH "OZONE" CARBURETTORS

Adjustment of level of fuel in the float-operated camera of DAAZ-2141, DAAZ-2140-50 and DAAZ-2140-70 carburetors

1 – carburetor cover;

2 – saddle of the needle valve;

3 – emphasis;

4 – needle valve;

5 – ball of the needle valve;

6 – ottyazhny fork of the needle valve;

7 – float lever uvula;

8 – float;

9 – laying of a cover of the carburetor;

Adjustment of level of fuel in the float-operated camera is carried out through each 30 thousand km, and also at the increased fuel consumption, replacement of the needle valve or a float.

PERFORMANCE ORDER
1. To uncover 1 carburetor and to be convinced that the float 8 has no dents and holes freely shakes on an axis, and its weight together with the mass of the lever is equal (12±1) g.
2. To check saddle inhaling density 2 needle valves in a cover 1 and lack of jammings of a ball of the 5th needle valve 4.
3. To establish a cover 1 vertically by the fuel supply union up. At the same time the needle valve 4 has to be closed, and the uvula of the 7th lever of a float to touch a ball of the 5th needle valve, without squeezing a ball spring.
4. To check in this situation a gap And between a middle part of a float and the surface of the laying 9 which is densely pressed to a cover flange. The gap has to be equal (6,5±0,25) mm. If necessary it is careful to turn in a uvula 7 for receiving the required gap. The uvula 7 has to be perpendicular axes of the needle valve, and its contact surface from a ball should not have damages which can be the cause of lag of the valve.
5. To check the course of a float which has to be (8±0,25) mm, if necessary turn in an emphasis 3.
6. To check whether the ottyazhny fork of the 6th needle valve interferes with its free movement.
7. To establish a cover of 1 carburetor into place, having convinced that the float can freely move, without touching walls of the float-operated camera.

ENGINES OF MODELS 331 AND 3313 WITH "SOLEKS" CARBURETTORS

Adjustment of level of fuel in the float-operated camera of DAAZ-21041 and DAAZ-21041-10 carburetors

1 – float;

2 – float lever uvula;

3 – valve;

4 – laying of a cover of the carburetor;

5 – carburetor cover

Adjustment of level of fuel in the float-operated camera is carried out through each 30 thousand km.

PERFORMANCE ORDER
1. To establish a cover of the 5th carburetor horizontally, floats up.
2. In this situation to check a gap between each float and laying 4, skintight to a cover. The gap has to be identical under each float and is equal (1±0,25) mm. If necessary 2 levers of a float for receiving the required gap are careful to turn in a uvula. The basic surface of a uvula has to be perpendicular axes of the needle valve 3 and should not have dents and забоин. For observance of the above-stated conditions and an exception of a possibility of a zadevaniye of floats for walls of the float-operated camera the careful podgibaniye of yokes of floats in the required plane is allowed.

Prevention

It is necessary to check installation of a float always when replacing a float or the needle valve; in the latter case it is necessary to replace also sealing laying of the valve.
