FUEL SYSTEM - Injection Nozzles (1 HD-T) FU-23
HINT: Align the holes of the nozzle body, distance piece
and nozzle holder body.
(c) Using a 14 mm deep socket wrench, torque the
retaining nut.
Torque: 350 kg-cm (25 ft-lb, 34 N m)
NOTICE: Over torquing could cause nozzle deforma-
tion and needle adhesion or other defects.
(d) Install the injection nozzle to the injection nozzle hand
tester and bleed air from the union nut.
CAUTION: Do not place your finger over the nozzle
injection hole.
(e) Pump the tester handle a few times as fast as possible
to discharge the carbon from the injection hole.
(f) Pump the tester handle slowly and observe the pres-
sure gauge.
(g) Read the pressure gauge just as the injection pressure
begins to drop.
No.2 opening pressure (Inspection pressure):
132-138 kg/cm
2
(1,877-1,963 psi, 12,945-13,533 kPa)
HINT: Proper nozzle operation can be determined by a
swishing sound.
If the opening pressure is not as specified, replace the
capsule sub-assembly.
HINT: The No.2 opening pressure is already adjusted for
the new capsule sub-assembly.
(h) There should be no dripping after injection.
