Exercise utmost cleanliness when recondi-
tioning an injector. Use no metallic tools for
cleaning, apart from wire brushes.
The job should preferably be entrusted to a speciali-
zed workshop.
Job:
Removing the Nozzle
Remove injector as per Job Card 07.07.01. Unscrew cap (12) - Fig. 1 - and remove gasket (13). Release sleeve
(11), turn out adjusting screw (10) by a few turns until spring (9) is unloaded. Clamp housing (4) at its flats in
a vice. Using wire brush, carefully remove combustion residues from the surface of the nozzle element (15),
avoiding damage to the nozzle bores, and remove washer (29). Then lay or suspend the injector in diesel
fuel to soak for 24 hours in order to soften the layer of carbon deposit between nozzle nut (7) and nozzle
element (24). Do not stand on end, otherwise the nozzle tip may be damaged.
When releasing nozzle nut (7), nozzle element (15) must be consistently contacting the flat surface of housing
(4), otherwise dowel pin (6) and possibly the bore in nozzle element (15) are liable to be damaged. For this
purpose, place a cleaning rag over the nozzle, and press the nozzle with the hand against the housing 4. When
released, remove stop bush (5) and nozzle element (15) with needle (16) from housing (4).
Clean all components in diesel fuel. Renew any damaged components.
To prevent corrosion, be sure to keep your fingers away from the lapped faced of housing (4), nozzle
element (15) and needle (16), once cleaning is finished.
