12-3.2 Nozzle inspection
(1) Inspect for scratches/wear
Inspect oil seals for abnormal scratches or wear and
replace nozzle if the nozzle sliding surface or seat are
scratched or abnormally wom.
(2) Check nozzle sliding
Wash the nozzle and nozzle body in clean diesel oil, and
make sure that when the nozzle is pulled out about half
way from the body, it slides down by itself when releas-
ed.
Rotate the nozzle a little; replace nozzle/nozzle body as
a set if there are some places where it does not slide
smoothly.
(3) Inspecting stop plate (inter-piece)
Check for scratches/wear in seals on both ends, check
for abnormal wear on the surface where it comes in con-
tact with the nozzle; replace if stop plate is excessively
wom.
