Setting start of delivery
Correct start of delivery by turning the
pump hub in the slotted holes of the drive
gear.
Remove cover above the injection pump
drive gear
Rotate engine with barring device until the
pointer is on the specified start of delivery
(scale disc ahead of vibration damper).
Unscrew timing case cover. Remove fixing
screws of injection pump impeller. Turn
the hub of the injection pump accordingly
until the line marks (pointer and injection
pump hub) are in alignment. After every
adjustment carefully retighten fixing
screws.
Recheck start of delivery.
Use new gaskets when mounting cover
and screw plug.
Note:
The D 2866 LE / LXE engines with fan-
cooled radiator are not equipped with
a scale disc in front of the torsional
vibration damper. Start of delivery in
these engines should be set by means
of the degrees scale on the flywheel.

1 Setting pointer
2 “OT” (top dead centre) mark and scale
3 Hexagon driver to rotate engine by
hand (Width across flats 32)
For the purpose of checking the start-of-
delivery setting, an “OT” (top dead centre)
mark and a scale from 10 ... 50° before
top dead centre is engraved on a disc
fitted in front of the torsional vibration
damper. The scale marks are read against
a pointer fitted to the crankcase.
There is another scale engraved on the
flywheel which can be read through an in-
spection hole in the flywheel housing but
access may be difficult. The scale should
be used for readjusting the pointer after
the vibration damper has been removed
or replaced.
In other words, before the vibration
damper with the scale disc is installed, the
engine should be positioned at “OT” (top
dead centre) by means of the scale on the
flywheel.
