Injection Pump Unit (for V2607-DI-E3B / V2607-DI-T-E3B)
(Removing the fuel injection pump unit)
1. Detach the window cover (2) for the fuel injection pump unit from
the flywheel housing.
2. Place the piston of the 4th cylinder at the top dead center in the
compression stroke. Fix the flywheel with the flywheel stopper.
IMPORTANT

• Look for the alignment mark (6) on the idle gear and the
injection pump gear. Using a white marking pen or the like,
put an alignment mark (6) on the engaged tooth of the both
gears. This helps to reassemble these gears in mesh later.
NOTE

• When the already existing alignment marks (6) align with
each other, there is no need to put another alignment mark
(6).
3. Unscrew the two plugs (3) of the injection pump unit.
4. Tighten the upper fuel camshaft lock screw (8) until it comes into
contact with the fuel camshaft. Make sure the camshaft does not
move any longer.
5. Tighten the lower fuel camshaft lock screw (8) until it comes into
contact with the fuel camshaft.
NOTE

• Never overtighten the lock screws when they have come into
contact with the camshaft. Otherwise the injection pump
itself may get damaged.
• Use of a socket set screw (dog point type) is recommended
for best results. Such screw can be constructed as shown
in figure (a).
6. Disconnect the lubricating oil pipe (4).
7. Using a white marking pen or the like, put an injection timing mark
(7) on the injection pump unit and on the crankcase 1.
8. Loosen the three injection pump unit mounting nuts (1).
9. Remove the injection pump unit support (5) and take out the
injection pump unit.
