2. Injector
a. Since most injector difficulties are
the result of dirt particles, it is
essential that a clean area be
provided on which to place the
injector parts after cleaning and
inspection.
WARNING
Wear protective eye goggles when using compressed air.
b. Wash all of the parts with clean
fuel oil or a suitable cleaning
solvent and dry them with clean,
filtered compressed air. Do not
use waste or rags for cleaning
purposes. Clean out all of the
passages, drilled holes and slots
in all of the injector parts.
c. Carbon on the inside of the spray
tip may be loosened for easy
removal by soaking for approxi-
mately 15 minutes in a suitable
solution prior to the external
cleaning and buffing operation.
Methyl Ethyl Ketone solution is
recommended for this purpose.
CAUTION
Care must be exercised when inserting the carbon
remover J9464-01 in the spray tip to avoid contacting
the needle valve seat in the tip.
