Clean all of the components; use a cleaning fluid
which can be diluted with water and refer to section 10
for relevant information. To remove heavy carbon
deposits from most components: soak them in
solutions of ’Maxan’ or ’Ardrox 667’.
Caution: Do not use the ’Maxan’ or ’Ardrox’
processes on the valve springs or the surface finish
will be damaged.
If cup plugs were removed, before the cylinder head
was cleaned, they must be renewed before the
cy linder head is given a test under pressure. Apply
’Loc tite 575’ to the new cup plugs and insert them into
their correct locations in the cylinder head. Us e the
relevant kit of remov al/replacer tools for the cup
plugs.
Make, locally, enough seals to close all of the
openings for coolant and fit them to the cylinder head.
Connect a pipe from a supply of air to the coolant
galleries. Apply air at a pressure of 207 kN/m² (30 lbf/
in²).
Caution: Do NOT exceed 207 kN/m² (30 lbf/in²) as
damage may be caused.
Put the cylinder head in a tank of water which is at a
temperature of 60°C (140°F) and inspect for bubbles
from around all the cup plugs and injector sleeves.
Renew plugs or sleeves which are not fully sealed.
Remove the seals from the openings for coolant.
Inspect the flame face for s igns of damage. If
necessary, the face may be reconditioned by surface
grinding, in four stages, to a maximum of 0,51 mm
(0.020 in). Information about work done must be
etched on an area of the flame face which is not under
the gasket of the cylinder head.
Caution: When a cylinder head flame face has been
machined, the valve seats must be re-cut to maintain
the correct distance between the valve faces and the
flame face of the cylinder head. See fits and
clearances on page 60.

To correct a valve seat
Special tools:
Valve seat tool, 21825 841
Valve seat cutter, 21825 842
12-12
It is recommended that all the valve guides are
inspected, and renewed as necessary, before the
work is begun on the v alve seat inserts. Ensure that
the bores of the guides are within the limits given at
the end of this section.
1 Inspect the inserts for erosion and cracks. If it is
necessary to correct the inserts, lightly lap the faces
of the valve seats and their relevant valves. To correct
the faces of more badly damaged valve seats, use the
valve seat tool, 21825 841, and the cutter, 21825 842,
together with the relevant pilot. To use the tool, fit the
guide (A) and proceed as s hown (B). Ensure that the
cutter is correct for the angle of the v alve seat, which
is giv en on page 60. The surface finish of the valve
seat will be improved if a compressed air supply is
used to remove debris during this operation.
Warning! Ensure that eye protection is used during
the above operation.
Caution: During the correction of a valve seat it is
important to remove only the minimum amount of
material.
2 After the inspection and correction of a valve seat
and the relevant valve, fit the valve into the guide and
check the depth of the head of the valve below the
flame face. If the depth is more than the limits given
on page 60 use a new valve to check again. If the
depth is then within acceptable limits, the new valve
must be fitted to the valve seat when the cy linder
head is assembled.
3 To ensure that the valve is fitted in its correc t
position, the number of the cylinder and the position
of the valve must be etched above the collet groove
on the valve stem. Valves must not be stamped or
A
B
222
223
marked with a centre punch, because crack s may
occur.
If the depth still exceeds the acceptable limits, a new
valve seat insert must be fitted.

To remove a valve seat insert
Special tools:
Holder, 21825 892
12-13
Cutter for the removal of valve seats, 21825 893
Expendable extractor, 21825 896
Caution: Before a valve seat insert for an exhaust
valve can be removed, the edge of the casting of the
cy linder head, which is rolled over the insert, must be
cut away (A). A special cutter, 21825 893, and holder,
21825 892, are available for this purpose.
1 If the relevant valve guide has not been removed,
and its bore is within the acceptable limits, turn the
cy linder head onto its side and slide the expendable
extractor, 21825 896, into the valve guide, until the
head is in contac t with the valve seat insert.
2 Weld electrically, at two or three equally spaced
positions around the circumferenc e, the expendable
extractor to the valve seat insert. Make the welds no
larger than is necessary in order to prevent damage
to the cylinder head.
3 Use a soft faced hammer on the end of the stem of
the expendable extractor to remove the old valve s eat
insert from its recess (B).
The expendable extractor may be used again if the
welds and the old valve seat insert are removed and
the head is ground lightly to eliminate the protrusions.

is given below:
1 Fasten securely the cylinder head on a milling
machine, and use a slot drill of approximately 10 mm
seat insert (A3). The depth of the slots should be 0,50
mm (0.020 in) less than the depth of the valve seat
insert. The minimum depth of the insert is 7,95 mm
(0.313 in). The slots should be apart by
Machine the slot to within 0,5 mm (0.020 in) of the
outside diameter of the insert.
2 Use a flat chisel, at the point which is indicated by
the arrow (A2) and in the direction of the opening in
the insert, to break the insert. Do not damage the
recess during this operation.
3 Remov e the insert and check that the recess is
clean and that there is no damage.
To fit a valve seat insert 12-14
Special tools:
Valve seat tool, 21825 841
Valve seat cutter, 21825 842
Drive handle, 21825 861

1 Valve seat inserts are available in two sizes,
oversize and standard. The oversize inserts are 0,05
mm (0.002 in) larger on the outer diameter. If an
oversize insert is to be fitted, ensure that it has the
correct part number: CV 14128 for an inlet seat or OE
47574 for an exhaust seat. Check als o that the wall
of the recess in the cylinder head will maintain the
correct interference fit, as given on page 60.
2 Cool the valve seat insert in liquid nitrogen to -35°C
(-31° F). Use the special tool, 21825 867, (B1) and the
B
226
handle, 21825 861 (B2), to fit the relevant insert into
its rec ess as rapidly as possible.
3 Use a 0,04 mm (0.0015 in) feeler gauge to c heck
that the bottom of the new insert is in full contact with
the bottom of the recess.
If a new v alve seat insert has been fitted for an
exhaust valve, the edge of the casting of the cylinder
head must be rolled over the chamfer which is around
the circumference of the insert. Proceed as follows :
4 Fasten securely the cylinder head on a s uitable drill
machine with the flame face in the upper position and
fit the rolling tool, 21825 894, and holder, 21825 892,
to the machine.

5 Apply clean engine lubricating oil to the rollers, to
the face at the end of the tool and to the c ounterbore
in the cylinder head.
6 Insert the rolling tool in the valve guide and turn
slowly the rolling tool. Apply enough pressure to
spread the material of the cylinder head over the
chamfer of the valve seat insert. Ensure that the face
at the end of the tool is suitably lubricated before the
face at the end of the tool is in contact with the top
face of the insert (A). When this occurs, the cylinder
head is fully rolled over the insert, and the tool can be
removed.
7 Use the valve seat cutter, 21825 842, and the
relevant pilot, to machine to the correct angle, the
seats which have been renewed. Ensure that the
cutter is correct for the angle of the valve seat, which
is given on page 60. Lap the valves to the seats.
Clean thoroughly the area around the valv es and the
seats and use engineer’s blue to check that the fac es
of the valves are in full contact across and around the
faces of the valve seats.
8 Fit the valves in their relevant seats and use a
straight edge and a feeler gauge to check that the
clearances between the heads of the valves and the
flame face are within the limits given on page 60. If a
clearance is excessive, a new valve must be fitted.
The number of the cylinder and the position of the
valve should be etched above the collet groove on the
A
227
valve stem. Valves must not be stamped or marked
with a centre punch, because cracks may occur.
To inspect the valve guides 12-15
Check the clearance of each valve stem in its guide.
This must be within the limits given on page 59. If the
clearance is excessive, use a new valve to check
again. If the c learance is still excessive, a new valve
guide must be fitted.

To renew a valve guide
Special tools:
Reamer for exhaust valve guides, 21825 755
Reamer for inlet valve guides, 21825 756
Valve seat tool, 21825 841
Valve seat cutter, 21825 842
Remover for inlet valv e guides, 21825 885
12-16
Remover for exhaust valve guides, 21825 886
Replacer for inlet valve guides, 21825 887
Replacer for ex haust valv e guides, 21825 888
Use the extractors: 21825 885 (inlet valves) or 21825
886 (exhaust valves), and the replacer tools 21825
887 (inlet valves) or 21825 888 (exhaust valves),
together with a suitable press.
1 Use the relevant extractors to press out the valve
guides that need to be renewed. Check the bores in
the cylinder head for wear or damage. See SRS 135
for instructions to correct worn bores.
2 Apply clean lubricating oil to the new guide before
it is inserted in the top end of the bore.
Caution: The guides for the inlet valves must be
inserted with the tapered end downward. The guides
for the exhaust valves must be inserted with the
internal chamfer, which is at one end of the bore, at
the top.
3 Fit the relevant replacer tool onto the guide and
press the guide in until the replacer tool is in c ontact
with the cylinder head (A). This will give the correct
protrusions of 12,8 mm (0.50 in) for the guides of the
inlet valves and 17,85 mm (0.70 in) for the guides of
the exhaust valves.
Caution: If liquid air is available, it may be help if the
new valve guide is cooled immediately before it is
fitted.
4 Use the correct reamer to ream the new valve guide
(B) and check the bore with the relevant plug gauge.
Use the reamer 21825 756 for inlet valve guides and
21825 755 for exhaust valve guides.
If new valve guides have been fitted, the relevant
valve seat insert must be corrected. Use the special
tool, 21825 842, to ensure concentricity.

Inspect the bridge pieces and the adjustment screws
for wear. Use a new guide as a gauge to c heck the
bores in the bridge pieces. Similarly, use a new
bridge piece to check the guides. Renew
components which have excessive wear.

Special tools:
Extractor for valve bridge guides, 21825 889
12-18
Depth plate for valve bridge guides, 21825 890
Use the extractor, 21825 889, to withdraw a worn
guide from its bore in the cylinder head (A). Clean
thoroughly the bore.
Apply ’Loctite 648’ to the area of the new guide which
is an interference fit in the cylinder head and use a
press to insert the guide into the c ylinder head. To
obtain the correct protrusion, fit the depth plate,
21825 890, ov er the guide and press the guide into its
bore until the top face is aligned precisely with the top
face of the depth plate (B).

To recondition a fuel injector sleeve
Special tools:
12-19
Tool holder for face cutter and reamer, 21825 765
Face cutter, 21825 767
Reamer, 21825 768
Service kit for fuel injector sleeves, 21825 915
Caution:
The fuel injector sleeves may be renewed
without the removal of the cylinder head from the
engine. In this situation, the coolant must be drained
until the level is below the cylinder head and the
piston, which is below the faulty fuel injector sleeve,
must be moved to BDC.
1 Use the integral face cutter and reamer to remove
deposits of carbon and to correct the face of the seat,
or the bore at the smaller internal diameter of the
injector sleeve (A). If the work is done without the
removal of the cylinder head from the engine, the
cutter and the reamer must be given a full application
of grease to retain the particles of the carbon and the
debris.
Caution: When the face cutter is used, remove only
the minimum material that is necessary to correct the
seat. The maximum permissible depth of the seat
from the top face of the cylinder head is 104,25 mm
