On later version engines
an
O-ring
has been introduced as a
seal between the injection pump and the block . Only so-called
hard shims may
be used on these engines when shimming .
Hard shims are available in thicknesses of 0 .2 mm (0 .0079 in),
0 .3 mm (0 .0118
in),
0 .6 mm
(0
.0024 in)
and 0 .9
mm
(0 .0354 in) .
16 . New
block
or camshaft
If
the block or the camshaft are replaced the block mustbe
measuredand marked, using the setting-disc p/n
884787
and a sliding caliper .
A . The setting-disc consists of two rings,
an
inner
and an
outer . The inner ring determines the injection angle for
each respective engine type, see Technical
Data (page 25) .
The
injection angle is stamped in degrees and is fixed with
a pin (1) .
B . Mount the setting-disc or the pulley with two
bolts, do
not tighten the bolts . Turn the
setting-disc
so that the guide
pin (2) comes in the largest of the four holes in
the pulley .
Press in the guide pin (2) so that the disc is
centered and
tighten the bolts .
The setting-disc is marked for
each respective cylinder :
