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 are 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.
The pointer should then be aligned such
that its measuring edge exactly coincides
with the “OT” mark on the scale disc.
In order to enable the engine to be rotated
manually during adjustments, there is a
plate with a central hexagon driver fitted
to the front of the crankshaft pulley (bar-
ring device).
Checking
Remove screw plug for inspection hole in
mounting flage of the injection pump.
Then rotate engine so that mark on
pointer fitted to injection pump coincides
with mark on pump hub.
Read degrees on scale engraved on disc
on torsional vibration damper.
The reading should equal the specified
start-of-delivery setting (see “Technical
Data”).
If not, correct start-of-delivery setting.
