2. Turn the crank pulley clockwise until V-groove of the
flywheel housing sight hole is aligned with the injection
timing degree of the engine.
3. Coincide the mark on pointer provided in injection pump
with the matching mark(FB) on the flange surface of the
drive gear by turning the flange in the oblonog holes of
the drive gear.
4. Tighten the bolt(M8) to specified torque, (2.2 kgf·m) not
to move the drive gear.
5. After confirmation that fastening bolts are completely
tightened check the start point (injection timing degree) of
fuel delivery setting once more if not right repeat it again
as same as upper way.
