CAUTION
Never use emery paper or any other metal
scraper to clean the nozzle.
Clean the nozzle seat with scraper as shown dipped in
test oil. Polish the needle seat with the piece of
hardwood dipped in test oil.
Clean the interior ring groove of the nozzle with the
scraper as shown. Rinse in solvent to remove all dirt
and carbon residue and dip in clean test oil.
Clean the spray holes of hole-type nozzles as shown
with the appropriate size cleaning needle.
Remove burned-on combustion deposits on all nozzles
with a commercially available cleaner. Rinse all parts in
clean test oil.
Clean the needle valve tip with a brass brush. Then,
inspect for rough surfaces or erosion. The pressure
shoulder will normally have a rough machined
appearance.
NOTE
Deteriorated needle valves must be replaced
as a matched unit with their compatible
nozzle body.
