6.3.1.13.1. A fuel injector


The prevention

Look safety measures in subsection 6.3.1 before the work beginning. If you consider that the injector has failed, try to clear it by means of corresponding means for clearing of injectors, such, as Holts Redex Injector Treatment.


Removal and installation

PERFORMANCE ORDER
1. Disconnect a wire of the negative plug of the accumulator.
2. Remove a casing of the air filter (subsection 6.3.1.2 see).
3. Walk along a wire from an injector and disconnect a connection socket.
4. Let out pressure from fuel system (subsection 6.3.1.7 see).
5. Turn off two fixing screws of a cap of an injector, then, remove a cap and linings.
6. Get an injector from the case throttle заслонки and remove sealing washers and consolidations.

The prevention

The injector can sit tight in the nest. In this case, do not try to extend it for wires. Remove the top part of the case throttle заслонки and push out an injector from a nest.


7. If it is necessary to replace an injector, it is necessary to release its wires from a connection socket.
8. For this purpose, remove a fixing clip behind a connection socket, then, by means of a small screw-driver, release corresponding wires and push out their plugs from a connection socket.
9. Remember or mark position of installation of each of wires in a socket of connection and try not to damage the plug of wires at their removal.
10. If you do not wish to assort a connection socket, the injector can be removed together with the device of increase in speed of work of the engine in a mode of idling and the additional valve of giving of air.
11. Installation is spent upside-down removals.
12. At installation it is necessary to pay attention to following moments.
13. Establish a new sealing washer and injector consolidations, and also, new linings for an injector cap.
14. At installation of a new injector, insert plugs of its wires into corresponding nests on a connection socket.
15. Check up, that they have been reliably fixed, then, establish a fixing clip behind a connection socket.
10. Check up, that wires correctly settled down in a connection socket. If is not present, after connection of a socket of connection the injector will not work correctly.
