bolts are free from paint . Should there be paint on the
bolts, there is always the risk of having an insufficiert
force in the bolt joint with subsequent leakagestighen as a
result . NOTE! The bolts are phospated, therefore do not
clean them with a steel-brush .
Coat the cylinder head bolts with molybdenum disulphide
and tighten them in accordance with the diagram, first to
20 Nm (2 .0 kpm/14.7 ft .lbs) and then to 70 Nm (7 .0 kpm/51.6
ft.lbs).
13 . Install the push rods and the rocker arm bridge, push
on new rubber rings to the oil pipe which is fitted at the
same time as the rocker arm bridge .
Adjusting the fuel injection pump location with shims
15 . if the same block camshaft and fuel Injection pumps
are used when assembling, the fuel injection pump must
be installed in their original positions and with the same
shim thickness as earlier . The so called soft shims, always
being installed against the block, must be replaced against
new ones . Carefully clean the contact surfaces between the
block and the fuel injection pumps and install shims with
thickness equal to the sum of the marking on the block and
that on the fuel injection pump, (4) earlier marking .
Example : The block marking 4 (= 4 tenths of a millimeter)
( .015748 in .)
The pump marking 4 (= 4 tenths of a millimeter)
( .015748 in .)
Total amount of shims = 0 .8 mm ( .031496 in .)
In this case select two soft shims 0 .2 and 0 .3 mm ( .011811
in .) . Place the hard shim between the two soft ones and
install the pump . NOTE! Never install a hard shim together
with another hard shim or against the block or the fuel
pump . Hard shims are available in thicknesses 0.3,
injecto
0 .6 and 0 .9 mm ( .011811, .02362, .035433 in . respectively) .
Soft shims are available in thicknesses 0 .2 and 0 .3 mm
( .007874 and .011811 in .) .
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 setting-disc
If the block or the camshaft are replaced the block must be
measured and 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
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 :

C . Turn cylinder no . 1 to it's injection. position . Place the
guide pin (2) in the setting-disc's hole marked cyl . 1 . Turn
the crankshaft a little against the normal direction of
and thereafter in the normal rotation direction until the
rotain
setting-disc's guide pin (2) goes in the timing cover's hole .
Measure using a caliper the distance between the cylinder
block and the roller lifter's edge (do not measure on the
roller) .
The distance should be :
2001 : 55 .8 mm (2.1 9685 in)
2002, 2003 : 55,6 mm (2 .18504 in)
2003T : 55 .9 mm (2 .2007 in)
17 . Fit the injection pump(s) together with the calculated
shim thickness . Turn the engine so that the cam for the
pump is not in the lifting position . Check that the pump's
pin locates in the control rod's groove and that the pump(s)
and the locks markings coincide (see figure) . Check after
fitting each pump that the control rod operates easily .
Tightening torque for the nuts is 20 Nm (2,0 kpm) (14.7
ft.lbs). Connect the fuel pipe between the pumps and the
pipe from the fuel filter to the injection pump . NOTE! The
hole bolt for the return hose has a smaller through-flow
channel than the others (on later versions it is marked
'Out " ) .
Example :
2001 . If the measured distance is 55 .2 mm (2 .17323 in) this
means that a shim with thickness 0 .6 mm (0 .02362 in) is to
be placed between the caliper and the block .
2002, 2003 . If the measured distance is 55 .0 mm (2 .16535
in) this means that a shim with thickness 0.6 mm (0 .02362
in) is to be placed between the caliper and the block.
The measured shims thickness (in this example 0 .6 mm) is
to be stamped into the block as in fig . 15.
The total shim thickness is found by adding the block's
measurements and the pump's marking .

In this case choose two soft shims 0 .2 and 0 .3 mm
(0 .007874 and 0 .011811 in) and one hard shim of 0 .3 mm
(0 .011811 in) . Place the hard shim between the two soft
ones and refit the pump . NOTE! A hard shim must never be
fitted together with another hard shim or directly against
the block or pump .
Hard shims are available in thicknesses 0 .3, 0 .6 and 0 .9 mm
(0 .011811, 0 .02362 and 0 .035433 in) .
Soft shims are available in thicknesses 0 .2 and 0 .3 mm
(0,007874 and 0 .011811 in) .
D . Repeat the procedure for the other pumps (2002, 2003)
in the same way as for cylinder 1 .
The setting-disc's marking is explained under point B .
