07-E3B SERIES, WSM
Checking Injection Timing (for V2607-DI-T-E3B / V3007-DI-T-
E3B / V3307-DI-T-E3B)
1. Make sure of matching the injection timing align mark (1) of the
injection pump unit and the flywheel housing, as shown in the
illustration.
2. Remove the injection pipes.
3. Remove the stop solenoid.
4. Turn the flywheel counterclockwise (viewed from flywheel side)
until the fuel fills up to the hole of the delivery valve holder (3) for
No.1 cylinder.
5. After the fuel fills up to the hole of the delivery valve holder (3) for
No.1 cylinder, turn back (clockwise) the flywheel around 1.6 rad
(90 °).
6. Turn the flywheel counterclockwise to set at around 0.17 rad
(10 ) before T.D.C..
7. Slowly turn the flywheel counterclockwise and stop turning when
the fuel begins to come up, to get the present injection timing.
8. Check to see the degree on flywheel.
The flywheel has mark "1TC" for the crank angle before the top
dead center of No.1 piston.
9. If the injection timing is not within the specification, rotate the
injection pump unit to adjust the injection timing.
IMPORTANT

• When installing the injection pump unit to the engine body,
follow the correct procedure.
See the "Injection Pump Unit".
