6.3.12. Removal and installation of nozzles

After a detachment of pressure head pipelines surely muffle openings in TNVD and nozzles.

Models with the M51 engine

Nozzle assembly

1 — the Holder of a nozzle
2 — the nozzle Case
3 — the Bringing opening

4 — the compression Chamber
5 — a nozzle Needle
6 — Returnable топливопровод


 PERFORMANCE ORDER

  1. Details of assembly of a nozzle are specified.
  2. Remove the inlet pipeline (see. Head Engine).
  3. Remove the holder of the pipeline and disconnect returnable fuel hoses.

The removed hoses replace.


  1. By means of a special cutting key give a cap nut of fastening of a tube to a removed nozzle. Close an opening from dirt hit in it. Weaken a cap nut of fastening of the corresponding tube to TNVD, if necessary holding from a provorachivaniye for the delivery valve.
  1. Turn out nozzle assembly by means of the adaptation No. 13 5 320.

Nozzle of the 4th cylinder with the lifting sensor needles (wire) to assort it is not allowed.

  1. Installation is made upside-down.

Models with the M57 engine

Close the generator from hit of working liquids on it.


 PERFORMANCE ORDER

  1. Remove the inlet pipeline (see. Head Engine).
  1. By means of a cutting key give cap nuts (1) fastening of pressure head pipelines (2) on a nozzle (4) and weaken nuts on the fuel distributive highway. Give a nut (3) and remove nozzles.
  1. If the sealing ring (1) did not remain on the removed nozzle (2), take it from a head of cylinders. Pay attention to the provision of a flange (3).
  1. Installation is made upside-down. Before installation clean channels of nozzles. Tighten nuts in the following sequence:
    1. Tighten all cap nuts of pressure head pipelines by hand;
    2. Tighten cap nuts on nozzles with demanded effort;
    3. Tighten cap nuts on the distributive highway and on TNVD.
  2. In case of replacement more than two nozzles it is necessary to execute correction of a field of characteristics of nozzles by means of the diagnostic device.

Models with the M67 engine

Below procedure of removal of nozzles on an example of the left number of cylinders (by No. No. 5 - 8) is given.


 PERFORMANCE ORDER

  1. Switch off ignition.
  1. Give cap nuts of fastening of pressure head pipelines (3) on a nozzle and on the fuel distributive highway by means of a cap natural a cut.

Thus keep knot from a provorachivaniye for the union of the pressure head pipeline on a nozzle.

  1. Remove pressure head pipelines.

After a detachment of pressure head pipelines surely muffle openings of injectors and pressure head pipelines.


  1. Wring out the socket (1) down, press a clamp (2) and separate the socket (1).
  1. Turn out bolts of fastening of nozzles, screw instead of bolts the special adaptation by means of which remove nozzles.
  1. If the sealing ring (1) did not remain on the removed nozzle (2), take it from a head of cylinders.
  2. Installation is made upside-down. Before installation clean channels of nozzles.
  3. In case of replacement more than three nozzles it is necessary to execute correction of a field of characteristics of nozzles by means of the diagnostic device.
