2.7.8. Removal, check and installation of fuel nozzles

Fuel nozzles
Fig. 2.270. Fuel nozzles



Removal
Dump residual pressure in топливопроводе that there was no fuel emission.

ATTENTION
To cover the union топливопровода with rags, to prevent fuel emission under the influence of residual pressure in топливопроводе.

Remove a fuel stage together with nozzles.

ATTENTION
At removal of a fuel stage accept precautionary measures not to allow loss of nozzles.
At removal of nozzles take measures for the prevention of an effluence of fuel.


Check of a technical condition

Check of resistance of a winding of a nozzle
Fig. 2.271. Check of resistance of a winding of a nozzle


Check resistance of a winding of a nozzle, having attached an ohmmeter to its conclusions (fig. 2.271).
Resistance of a winding of nozzles: 15,9±0,35 Ohm at 20 °C.
At discrepancy of resistance to norm replace a nozzle.

Installation

Fuel nozzle
Fig. 2.272. Fuel nozzle


Establish on a nozzle a new sealing and heat-shielding ring (fig. 2.272).
Put on a sealing ring solvent, veretenny oil or gasoline.

Nozzle installation
Fig. 2.273. Nozzle installation


Establish a nozzle in a fuel stage, turning a nozzle to the left-to the right (fig. 2.273).
Be convinced of ease of rotation of a nozzle.

NOTE
The complicated rotation of a nozzle indicates a possible distortion of a sealing ring. Remove a nozzle, insert it into a fuel stage and again check ease of rotation.
