Removal and installation of nozzles

Faulty nozzles can cause a strong detonation of the engine and lead to damage of bearings. In this case to leave the engine to idle and weaken serially cap nuts of nozzles. If when weakening one of nuts the detonation disappears, it indicates a faulty nozzle.

1 — the exhaust silencer of noise of an admission and the resonant channel
2 — injection pipelines

3 — returnable топливопровод
4 — nozzles
5 — laying and washers

The faulty nozzle can be revealed also, weakening serially cap nuts when the engine works with number of turns of fast idling. If the number of turns after weakening of one of nozzles remains invariable, means, this nozzle is faulty. The nozzle can be checked by means of a manometer. (It is carried out in a workshop; demanded pressure of dispersion: 110 Bar).

First signs of malfunction of nozzles:

    Ignition interruptions Detonation in one or several cylinders The engine overheats Engine capacity falling Excessively strong black exhaust cloud High fuel consumption

Removal

 PERFORMANCE ORDER

    To disconnect a weight cable from the battery.

Data from memory of malfunctions of the engine or protective code of a radio receiver are thus erased. Before shutdown of the battery it is necessary to read instructions in the Section Removal and battery installation.

    To unscrew the exhaust silencer of noise of an admission and the resonant channel. Carefully to clear outside pipelines of injection and returnable топливопроводы a cold cleaner. To remove injection pipelines in a set, for this purpose to weaken cap nuts on TNVD and nozzles the cut-through cap key.

Not to change a bend form.

    To remove a fuel hose from the returnable pipeline and to weaken a lock-nut, to remove laying and the returnable pipeline. To remove nozzles and to spread out as installation.

Through openings of nozzles dirt should not get to chambers of combustion.

    In each opening there are still laying and a washer which should be replaced. To check a nozzle needle on wear and damages, to remove a soot with a wooden shpatel.

Not to process at all a nozzle or a nozzle needle a wire, a file or an emery paper. Not to mix separate elements of nozzles among themselves.

Installation

 PERFORMANCE ORDER

    To establish 4 new laying and washers.

To watch adjusting situation, the dark blue label should be turned up.

    To establish nozzles and to tighten with effort of 65 Nanometers.

Peretyazhka of holders of nozzles can lead to deformation of nozzles and jamming of needles of nozzles or other damages.

    To establish returnable топливопровод with new laying and to tighten nuts with effort of 30 Nanometers. To establish injection pipelines, to tighten cap nuts with effort of 30 Nanometers. On all holders of nozzles a few to weaken cap nuts of pipelines of injection. To turn the crankshaft a starter while on pipelines fuel will not act. To tighten pipelines with the ordered effort. To establish the exhaust silencer of noise of an admission and the resonant channel.
    To connect a weight cable to the battery.
    If are available, to establish time on hours and to set a protective code of a radio receiver.
