Adjusting The Valve Clearance; Checking The Injection Angle - Volvo 2001 Workout Manual

12 . Tighten the two guide screws p/n 884840 in the block
and install the cylinder head gasket with the marking
"Top" facing upwards . Install the cylinder head .
Make sure that the contact surface for the cylinder head
bolts are free from paint . Should there be paint on the
bolts, there is always the risk of having an insufficiert
t i g h t e n i n g force in the bolt joint with subsequent leakages 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 .
14 . Valve clearance cold/warm engine 0 .30 mm (.01181
in .) . Turn the engine in the direction of rotation until the
valves in one cylinder are "rocking" . Then turn the engine
one turn more and
adjust
the valves for this cylinder .
R e p e a t the procedure for the remaining cylinders .
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
i n j e c t i o n pump . Hard shims are available in thicknesses 0.3,
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 .) .
