CAUTION
!
• Be sure not to interfere high pressure pipe
with glow plug.
• Before installing high pressure pipe, be
sure to lubricate not threads with oil
included in spare part without allowing oil
into high pressure pipe.
Do not lubricate high pressure pipe
supplied without oil so that this fuel pipe is
lubricated previously.
• For high pressure pipe between fuel injector and
common rail
a. Remove plug caps from fuel injector and
common rail.
b. Tighten high pressure pipe union nut as
follows.
i. Tighten fuel injector side union nuts then
common rail side union nuts by hand.
ii. Tighten common rail bolts to specified
torque.
Tightening torque
Common rail bolt: 22 N·m (2.2 kgf-m,
16.0 lb-ft)
iii. Tighten fuel injector side union nut then
common rail side union nut to specified
torque in the same manner as removal
procedure.
Tightening torque
High pressure pipe union nut (Type 2):
25 N·m (2.5 kgf-m, 18.0 lb-ft)
High pressure pipe union nut (Common
rail to fuel injector) (Type 3): 27 N·m (
2.7 kgf-m, 19.5 lb-ft)
• For high pressure pipe between injection pump
and common rail
a. Remove plug caps from fuel injector and
common rail.
b. Tighten high pressure pipe union nut as
follows.
i. Tighten injection pump side union nuts
then common rail side union nuts by hand.
ii. Tighten common rail mounting bolts to
specified torque.
Tightening torque
Common rail mounting bolt: 22 N·m (
2.2 kgf-m, 16.0 lb-ft)
iii. Tighten injection pump side union nut then
common rail side union nut to specified
torque in the same manner as removal
procedure.
