Oil is s upplied to the bearings of the ’A’ bank
turbocharger, to the fuel injection pump (A3) and to
the governor (A2) through a pipe from the heat
exchanger, or mounting adaptor for early engines.
Another pipe from the same position supplies oil to
the ’B’ bank turbocharger. Drain pipes return the oil
from the fuel injection pump (A4), from the governor
(A1) and from each turbocharger to the crankcase
and the sump.
The heat exchanger consists of a single tube stack in
a casing of aluminium alloy . On early engines, it is
fitted to a mounting adaptor on the ’B’ bank side of the
crankcase.
New engines have a single piece heat exchanger
which is mounted directly on the c rankcase.
The coolant flows through the tubes ; the lubricating oil
passes over the outside of the tubes and the direction
of flow is controlled by a series of baffles to obtain the
maximum reduction of temperature. On early
engines, the relief valve (A10) is fitted in a housing at
the front end of the mounting adaptor. It has an
arrangement of a plunger and spring and allows
excessive oil to return to the sump when the pressure
exceeds 414 kN/m (60 lbf/in ).
A warning switch for the oil pressure is also fitted to
the mounting adaptor.
On new engines, the relief valve is fitted in a housing
at the end of the single piece heat exchanger at the
flywheel end. The warning switch is fitted to an elbow
between the heat exchanger and the main oil gallery.
The oil filler consists of a flanged pipe with a filler cap.
It is fitted over the ’A’ bank side of the sump well.
The dipstick is held in a tube next to the oil filler and
consists of a flat steel blade which is bent to provide
clearance from the tube wall. Notches are machined
in the blade to indicate the maximum and minimum
permissible levels for the lubricating oil.

It is recommended that this operation is
If there is enough clearance below the engine, the
sump may be removed while the engine is connected
to its driven unit. It is important to conform to the
normal safety precautions, such as to disconnect the
circuit of the starter motor.
1 Remov e the drain plug of the sump and drain the
oil into a suitable container. Fit the drain plug and
tighten it to the correct torque.
2 Remove the bolts and the washers which retain the
sump to the sump adaptor, and lower carefully the
sump. Remove the bobbin which is fitted between the
suction side of the lubricating oil pump and the base
of the sump. Remove and dis card the sump joint.
To fit
1 Make locally two suitable guide studs and fit them
to the sump adaptor. Put a new joint on the joint face
of the sump, with the bolt holes correctly aligned.
2 Renew the ’O’ rings on the bobbin which is fitted
between the suction side of the lubricating oil pump
and the base of the sump.
3 Lubricate the new ’O’ rings with clean engine
lubricating oil, fit the suction pipe into its location in the
sump and lift the sump up to the sump adaptor.
Ensure that the suction pipe remains in its correct
position and enters the inlet of the lubricating oil pump
during the operation.
4 Fit the bolts, which retain the sump, complete with
the plain washers and the new spring washers, and
tighten them to a torque of 55 Nm (40 lbf ft).
To clean and inspect 19-2
1 Clean thoroughly the sump with kerosene and dry
with compressed air. Check that the oil strainer is free
from sediment and is undamaged. Inspect the sump
for cracks or other damage and remove any of the
material of the old joint which remains on the sump
and the sump adaptor.
done with the engine fitted in a build stand.
To remove
1 Remov e the lubricating oil sump, operation 19-1.
2 Remove the blanking plug of the oil gallery from the
’B’ bank side of the sump adaptor and withdraw the
bobbin from the discharge side of the lubricating oil
pump.
3 Remov e all the bolts which secure the sump
adaptor to the crankcase and to the timing case and
remove the sump adaptor.
Caution: Unless the timing case is also to be
removed, use care during the removal of the sump
adaptor from the timing case to prevent damage to
the joint. If this is not possible, remove all of the
section of the joint which can be seen and clean the
joint face.
To fit
Caution: A new joint for the joint faces of the
crankcase and the sump adaptor has a strip which
connects the sides and prevents damage to the joint
while it is in storage. Before the joint is fitted to the
joint fac e, cut away the strip between the two sides at
the end of the joint which is next to the timing case.
Do not cut into the two sides of the joint, which must
extend to the joint of the timing case.
1 If the fan adaptor has been fitted to the crankcase
with a new joint, cut away carefully the protrusions at
the two ends of the joint until the ends are aligned
precisely with the joint faces of the crankcase.
2 For early engines, if the area of the joint between
the sump adaptor and the timing cas e is to be
renewed, cut the section from a new joint. Ens ure that
there is full contact with the remainder of the original
joint. The joint may be held in position with a single,
and very small, application of grease between each
bolt hole.
3 Apply Hylomar PL 32 sealant along the two corners
where the joints are in contact and also at the two
places where the joint between the fan adaptor and
the crankcase is seen.
4 Check that the two spring type dowels are fitted and
put the new joint on the joint face of the crankcase.
Ensure that all the bolt holes are aligned correctly.
Ensure also that the ends of the joint make full contactwith the joint of the timing case. The joint may be held
in position with a single, and very small, application of
grease between each bolt hole. Apply Hylomar PL 32
sealant along the two corners where the joints are in
contact.
Caution: It is important that this procedure is done
correctly to prevent leakage of the oil during the
operation of the engine. Ensure that the joint between
the sump adaptor and the timing c ase remains in its
position and is not damaged when the sump adaptor
is fitted.
5 Fit carefully the sump adaptor.
6 Fit loosely the 14 bolts with plain washers and new
spring washers into eac h side of the flange of the
sump adaptor, and the four bolts with plain washers
and new spring washers into the front edge of the
flange.
Caution: If the timing case is not yet fitted, refer to
operation 19-5 (to fit), paragraph 5.
7 Fit the five bolts, with plain washers and new spring
washers, through the bolt holes in the lower edge of
the timing case flange. Tighten lightly the bolts.
8 Start with the four bolts nearest to the corners
where the joints are in contact and tighten, evenly and
gradually, all the bolts which retain the sump adaptor.
Tighten the bolts to 55 Nm (40 lbf ft).
9 Fit new ’O’ rings into the grooves of the bobbin
which is fitted to the discharge side of the lubricating
oil pump. Apply a suitable quantity of clean engine oil
to the ’O’ rings and insert the bobbin into the outlet of
the lubricating oil pump through the opening in the
sump adaptor. Ensure that the small holes which are
drilled ac ross the bobbin are inside the oil gallery of
the sump adaptor.
10 Fit a new ’O’ ring around the spigot on the plug
which closes the oil gallery. Insert the plug and retain
it with two bolts, complete with plain washers and
spring washers. Tighten securely the bolts.
11 Fit the lubricating oil sump, operation 19-1.
1 Clean thoroughly the sump adaptor with kerosene
and dry with compressed air. Inspect for cracks or
other damage and remove all of the material of the old
joints which remains on the sump adaptor and the
crankcase.
Single piece lubricating oil sump
To remove and to fit
To remove
If there is enough clearance below the engine, the
sump may be removed while the engine is connected
to its driven unit. It may be an advantage to remove
also the filler assembly. It is important to conform to
the normal safety precautions, such as to disconnect
the circuit of the starter motor.
1 Remove the drain plug of the sump and drain the
oil into a suitable container; replace the drain plug and
apply only the correct torque of 47 Nm (35 lbf ft) to
tighten it.
2 Remove the elbow connection and the joint from
the ’B’ bank side of the sump and withdraw the bobbin
from the discharge side of the lubricating oil pump.
Remove the short bobbin which is the connection to
the heat exchanger.
3 Remove the bolts and the spring washers which
secure the sump to the crankcase and to the timing
case, and lower carefully the sump. Remove the
shorter bobbin which returns oil from the relief valve
to the sump.
Caution: Unless the timing case is also to be
removed, use care during the removal of the sump to
prevent damage to the common joint. If this is not
possible, remove all of the section of the joint which
can be seen and clean the joint faces .
To fit
1 Fit the new joint as for the sump adaptor, see
operation 19-3 paragraphs 1 to 4.
Caution: It is important that this procedure is done
correc tly to prevent leakage of the oil during the
operation of the engine. Ensure that the joint between
the sump and the timing case remains in its position
and is not damaged when the sump is fitted.
2 Fit new ’O’ rings to the small bobbin which returns
oil from the heat exchanger to the sump, lubricate
them with clean engine lubricating oil and fit the
bobbin to the sump.
3 Lift up the sump to the c rankcase and ensure that
the small bobbin engages correctly with the inlet in the
heat exchanger. Ensure also that the sump does not
hit the assembly of the suction pipe and the strainer.
Two long M10 bolts may be used as hand grips to lift
the sump to the correct position when the engine is
inverted in a build stand. The bolts are inserted in the
tapped holes which retain the coolant crossover pipe
below the sump.
4 Fit loosely the 14 bolts and new spring washers into
each side of the flange of the sump and the four bolts
and new spring washers into the front edge of the
flange.
5 If the timing case is not yet fitted, measure the s tep
between the joint faces of the c rankcase and the
sump (or the sump adaptor if relevant) on both the ’A’
and the ’B’ bank sides of the engine The step must be
less than 0,1 mm (0.004 in) on each side. If the step
is more, the position of the sump (or sump adaptor)
must be adjusted.
6 Fit the five bolts, with new spring washers, through
the bolt holes in the lower edge of the timing case
flange. Tighten lightly the bolts.
7 Start with the four bolts nearest to the corners
where the joints are in contact and tighten, evenly and
gradually, all the bolts which retain the sump. Tighten
the bolts to 55 Nm (40 lbf ft).
Caution: For new engines only which have the
steel joint CV14584 between the timing case and the
crankcase/sump face, the five bolts which fasten the
timing case to the sump are of a higher tensile
strength and must be tightened evenly and gradually
to 75 Nm (55 lbf ft).
8 Fit new ’O’ rings to the grooves of the bobbin which
is fitted to the discharge side of the lubricating oil
pump, lubricate them with clean engine lubricating oil
and fit the bobbin. Fit new ’O’ rings to the smaller
bobbin, which is the connection to the heat
exchanger, lubricate them with clean engine
lubricating oil and fit the bobbin into the elbow
connection. Fit the assembly of the elbow connection
and a new joint to the ’B’ bank side of the sump with
three bolts and new spring washers.
9 If relevant, fit the filler assembly to the sump,
complete with a new gasket.
To clean and inspect
1 Clean thoroughly the sump with kerosene and dry
with compressed air. Inspect the sump for cracks or
other damage and remove all of the material of the old
joints which remains on the joint fac es. Check that
the strainer on the suction pipe of the lubricating oil
pump is free from sediment and is undamaged, and
that the assembly of the suction pipe and its support
bracket is secure.
