Inspection (No.2-4nozzle)
Thoroughly clean all disassembled parts with fresh kerosene or
solvent.
IIf nozzle needle is damaged or fused, replace nozzle assem-
bly with a new one.
I If end of nozzle needle is seized or excessively discolored,
replace nozzle assembly.
I Check nozzle body and distance piece for proper contact. If
excessively worn or damaged, replace nozzle assembly or dis-
tance piece.
I Check nozzle spring for excessive wear or damage. If exces-
sively worn or damaged, replace it with a new spring.
I Check distance piece and nozzle holder for proper contact. If
excessively worn or damaged, replace nozzle holder assembly.
Cleaning (No.2-4nozzle)
a. Do not touch the nozzle mating surface with your fingers.
b. To wash the nozzles, use a wooden stick and brass brush
with clean diesel fuel.
1. Remove any carbon from exterior of nozzle body (except wrap- ping angle portion) by using Tool.
2. Clean oil sump of nozzle body using Tool.
3. Clean nozzle seat by using Tool.
Take extra precautions when performing this job, since nozzle
efficiency depends greatly on a good nozzle seat.
