FU-14 FUEL SYSTEM - Injection Nozzles (1 PZ and 1 HZ)
ASSEMBLY OF INJECTION NOZZLES
(See page FU-12)
1. ASSEMBLE INJECTION NOZZLE HOLDERS
(a) Assemble the nozzle holder retaining nut, the nozzle
assembly, distance piece, pressure pin, pressure
spring, adjusting shim and nozzle holder body, and
finger tighten the retaining nut.
(b) Using SST, tighten the retaining nut.
SST 09268-64010
Torque: 375 kg-cm (27 ft-lb, 37 N m)
NOTICE: Over torquing could cause nozzle deforma-
tion and needle adhesion or other defects.
2. PERFORM PRESSURE AND SPRAY PATTERN TEST
(See pages FU-10, 11)
INSTALLATION OF INJECTION NOZZLES
(See page FU-9)
1. INSTALL INJECTION NOZZLES
(a) Place new gaskets and the nozzle seats into the
injection nozzle holes of the cylinder head.
(b) Using SST, install the injection nozzles.
SST 09268-64010
Torque: 650 kg-cm (47 ft-lb, 64 N m )
NOTICE:
• Over torquing could cause nozzle deformation and
needle adhesion or other defects.
• When installing the injection nozzle, never torque
the nozzle holder body. Torque the retaining nut
section.
2. INSTALL NOZZLE LEAKAGE PIPE
(a) Install new gaskets and the leakage pipe with the nuts.
Torque: 300 kg-cm (22 ft-lb, 29 N m )
(b) Connect the fuel hose to the return pipe.
