GENERAL INFORMATION

Prevention

For check of turns of idling and the contents WITH in exhaust gases it is necessary to use a tachometer and the analyzer of exhaust gases. At installation of a casing of cooling it is necessary to use new sealing rings.


Removal

PERFORMANCE ORDER
1. Remove a weight wire from the accumulator.
2. On early models remove the air filter. On later models disconnect an air pipe from the air filter, then disconnect a vacuum pipe and a hose of ventilation of a case from the air chamber. Unscrew three screws and remove the air chamber together with an air line.
3. Note the provision of adjusting labels of a bimetallic casing, and at their absence put labels which are necessary for using for simplification of installation. Unscrew three screws and remove a bimetallic casing. Move a casing aside, thus do not deform hoses of supply of cooling liquid and electroconducting of a heater of a zaslonka.
4. Unscrew three screws of fastening of a zaslonka to the carburetor case, then take a zaslonka, thus do not bend draft of a zaslonka.
5. Before removal of a bimetallic casing note the provision of a hose of cooling liquid of an automatic air zaslonka for simplification of installation, then disconnect hoses. Close hoses suitable jams or fix them in the top situation for reduction of losses of cooling liquid.
6. Disconnect the electric socket from a heater of a zaslonka and remove a bimetallic casing.
7. Unscrew the central bolt of fastening and remove a cooling casing about bimetal of a lichesky casing. Remove sealing rings from under a head of a bolt and from the case of a casing of cooling.

Installation

PERFORMANCE ORDER
1. Establish zaslonka knot on the carburetor case. Thus connect the zaslonka lever to draft and fix three screws.
2. Check and, if necessary, adjust a gap of an air zaslonka and the provision of a cam of the accelerated turns of idling.
3. Connect a bimetallic spring to the lever of an air zaslonka, then establish a casing of a bimetallic spring on a casing of an automatic air zaslonka and fix screws, without tightening them it is final. Combine adjusting labels of a bimetallic casing with labels of a casing of an air zaslonka and finally tighten fastening screws.
4. At existence establish a cooling casing on a casing of a bimetallic spring. Thus use new a sealant aching a ring. Connect hoses of supply of cooling liquid and the electric socket of a heater of a zaslonka.
5. Further installation make in sequence, return to removal taking into account the next moments.
6. If hoses of supply of cooling liquid were disconnected check level of cooling liquid and, at bypass pave, finish it to norm.
7. Check and, if necessary, adjust the accelerated turns of idling.

Adjustment

AIR ZASLONKA'S GAP

Adjustment of a gap of an air zaslonka

1–control lever zaslonka;

2–adjusting uvula;

In – a gap of an air zaslonka


PERFORMANCE ORDER
1. Note the provision of adjusting labels of a bimetallic casing, and at their absence put labels which are necessary for using for simplification of installation. Unscrew three screws and remove a bimetallic casing. Move a casing aside, thus do not deform hoses of supply of cooling liquid and electroconducting of a heater of a zaslonka.
2. Unscrew three screws of fastening of a zaslonka to the carburetor case, then take a zaslonka, thus do not bend draft of a zaslonka.
3. Before removal of a bimetallic casing note the provision of a hose of cooling liquid of an automatic air zaslonka for simplification of installation, then disconnect hoses. Close hoses suitable jams or fix them in the top situation for reduction of losses of cooling liquid.
4. Turn the zaslonka lever clockwise against the stop and an elastic band fix it in this situation.
5. Move the lever before complete opening of a butterfly valve and measure a gap of an air zaslonka between the bottom party of a zaslonka and a wall of the primary chamber.
If necessary adjust a gap of an air zaslonka, turning in регулиро a vochny uvula (2). If a gap of an air zaslonka less demanded, using a screw-driver edge, increase a gap "In". If a gap of an air zaslonka more demanded, reduce a gap "In", using flat-nose pliers (see fig. Adjustment of a gap of an air zaslonka).
After carrying out adjustment establish a bimetallic casing as it is stated earlier in this section.

THE PROVISION OF THE CAM OF THE ACCELERATED TURNS OF IDLING

Adjustment of a cam of the accelerated turns of idling

1–a cam of the accelerated turns of idling;

2–adjusting lever;

3–lever of a drive of a zaslonka;

4–the screw of adjustment of the accelerated turns of idling


PERFORMANCE ORDER
1. Remove a casing of a bimetallic spring and adjust a gap of an air zaslonka "In".
2. Open a butterfly valve, then close an air zaslonka, thus pressing a hand finger on the lever of a drive of a zaslonka (see fig. Adjustment of a cam of the accelerated turns of idling). Close a butterfly valve.
3. Check that the screw of adjustment of the accelerated turns of idling was established on the second step of a cam of the accelerated turns of idling.
4. If it is necessary to make adjustment, first of all check correctness of placement of a returnable spring of a zaslonka, then turning in the lever, execute adjustment.
5. Establish a casing of a bimetallic spring.

THE ACCELERATED TURNS OF IDLING


Prevention

For adjustment of the accelerated turns of idling it is necessary to use an exact tachometer and the analyzer of exhaust gases.


Adjustment of the accelerated turns of idling

3–the screw of adjustment of the accelerated turns of idling;

4–screw placement on the step of a cam second from above


Arrangement of the cap closing the screw of adjustment of accelerated turns of idling

PERFORMANCE ORDER
1. Check turns of idling and the contents WITH in exhaust gases. If necessary adjust idling turns.
2. Start the engine and warm up it to normal working temperature, then connect a tachometer according to the maintenance instruction.
3. Establish the screw of adjustment of the accelerated turns of idling on the second step of a cam of the accelerated idling (see fig. Adjustment of the accelerated turns of idling).
4. Start the engine and, without touching an accelerator pedal, check turns of the accelerated idling.
5. In need of adjustment switch off the engine and remove a cap from the screw of adjustment of the accelerated turns of idling (see fig. An arrangement of the cap closing the screw of adjustment of accelerated turns of idling).
6. Check that the screw of adjustment of the accelerated turns of idling is established on the step of a cam second from above, then start the engine, without touching an accelerator pedal.
7. Rotating the adjusting screw, establish demanded turns of the accelerated idling.
8. If in the course of adjustment of the accelerated turns of idling the radiator fan turns on, stop регулиров ку and continue it only after switching off of the fan of a radiator.
9. After carrying out adjustment switch off the engine and disconnect a tachometer.
10. Establish the new cap closing the screw of adjustment of accelerated turns of idling.
