Provide good aeration of a workplace! Pairs of fuel are poisonous, avoid application of open fire because of danger of emergence of a fire!

1. Disconnect from the plug of the storage battery a weight wire (–).

The anticreeping code of radio is thus erased.

2. Reduce pressure паров fuels, for this purpose quickly open a cover of a bulk mouth of a fuel tank.
3. Remove a cross-section pipe of the air filter.
4. Remove a hose (1) for air removal from a case.
5. Remove a hose (40/11) being under depression.
6. Remove from the coil of ignition of a wire of a high voltage and disconnect them from spring clips on the fastening device.
7. Unscrew bolts (17/4) of clips топливопровода (17/5). Pay attention to that nuts (17/6) did not drop out.
8. Turn off submitting (17/2) and drain (17/3) топливопроводы. For this purpose weaken a cap nut and a hollow bolt (17/7).

Before separation топливопроводов lay thick rags over connections to catch the remains of the fuel which are thrown out by probably remained residual pressure.

9. Remove shtekkerny sockets of klapanny nozzles (arrow).
10. Unscrew bolts (17/1) and remove rasporny plugs (17/8).
11. Carefully extend from the inlet gas pipeline the fuel distributor (17) together with klapanny nozzles.


1. Insert the fuel distributor with new sealing rings of round section.
2. Insert rasporny plugs and screw the fuel distributor.
3. Pull the shtekkerny socket for klapanny nozzles.
4. Screw топливопроводы with new sealing rings.
5. Fix the drain pipeline on the fuel distributor by means of clips.
6. Get wires of a high voltage on coils of ignition and fix them in spring clips on the fastening device.
7. Get a hose for air removal from a case so that shooters on a hose and a rubber flange stood opposite to each other.
8. Establish a cross-section pipe of the air filter.
9. Attach to the plug of the storage battery a weight wire (–).
10. Establish time on hours.
11. Enter an anticreeping code of radio.
12. Start the engine and check tightness of junctions топливопроводов.
