INFORMATION PREPARATION
1.Clean components and surrounding area prior to
removal.
2.Blank off any openings exposed by component
removal using greaseproof paper and masking
tape.
3.Immediately seal fuel, oil or hydraulic lines when
separated, using plastic caps or plugs, to
prevent loss of fluid and entry of dirt.
4.Close open ends of oilways, exposed by
component removal, with tapered hardwood
plugs or readily visible plastic plugs.
5.Immediately a component is removed, place it in
a suitable container; use a separate container for
each component and its associated parts.
6.Before dismantling a component, clean it
thoroughly with a recommended cleaning agent;
check that agent is suitable for all materials of
component.
7.Clean bench and provide marking materials,
labels, containers and locking wire before
dismantling a component.
DISMANTLING
1.Observe scrupulous cleanliness when
dismantling components, particularly when
brake, fuel or hydraulic system parts are being
worked on. A particle of dirt or a cloth fragment
could cause a dangerous malfunction if trapped
in these systems.
2.Blow out all tapped holes, crevices, oilways and
fluid passages with an air line. Ensure that any
O-rings used for sealing are correctly replaced or
renewed, if disturbed.
3.Use marking ink to identify mating parts, to
ensure correct reassembly. If a centre punch or
scriber is used they may initiate cracks or
distortion of components.
4.Wire together mating parts where necessary to
prevent accidental interchange (e.g. roller
bearing components).
5.Wire labels on to all parts which are to be
renewed, and to parts requiring further
inspection before being passed for reassembly;
place these parts in separate containers from
those containing parts for rebuild.
6.Do not discard a part due for renewal until it has
been compared with the new part, to ensure that
its correct replacement has been obtained.INSPECTION-GENERAL
1.Never inspect a component for wear or
dimensional check unless it is absolutely clean;
a slight smear of grease can conceal an incipient
failure.
2.When a component is to be checked
dimensionally against figures quoted for it, use
correct equipment (surface plates, micrometers,
dial gauges, etc.) in serviceable condition.
Makeshift checking equipment can be
dangerous.
3.Reject a component if its dimensions are outside
limits quoted, or if damage is apparent. A part
may, however, be refitted if its critical dimension
is exactly limit size, and is otherwise satisfactory.
4.Use’Plastigauge’12 Type PG-1 for checking
bearing surface clearances. Directions for its
use, and a scale giving bearing clearances in
0,0025 mm steps are provided with it.

INFORMATION BALL AND ROLLER BEARINGS
CAUTION: Never refit a ball or roller
bearing without first ensuring that it is in a
fully serviceable condition.
1.Remove all traces of lubricant from bearing
under inspection by washing in a suitable
degreaser; maintain absolute cleanliness
throughout operations.
2.Inspect visually for markings of any form on
rolling elements, raceways, outer surface of
outer rings or inner surface of inner rings. Reject
any bearings found to be marked, since any
marking in these areas indicates onset of wear.
3.Holding inner race between finger and thumb of
one hand, spin outer race and check that it
revolves absolutely smoothly. Repeat, holding
outer race and spinning inner race.
4.Rotate outer ring gently with a reciprocating
motion, while holding inner ring; feel for any
check or obstruction to rotation, and reject
bearing if action is not perfectly smooth.
5.Lubricate bearing generously with lubricant
appropriate to installation.
6.Inspect shaft and bearing housing for
discolouration or other marking suggesting that
movement has taken place between bearing and
seatings. (This is particularly to be expected if
related markings were found in operation 2).
7.Ensure that shaft and housing are clean and free
from burrs before fitting bearing.8.If one bearing assembly of a pair shows an
imperfection it is generally advisable to replace
both with new bearings; an exception could be
made if the faulty bearing had covered a low
mileage, and it could be established that
damage was confined to it only.
9.When fitting bearing to shaft, apply force only to
inner ring of bearing, and only to outer ring when
fitting into housing, as shown above.
10.In the case of grease lubricated bearings (e.g.
hub bearings) fill space between bearing and
outer seal with recommended grade of grease
before fitting seal.
11.Always mark components of separable bearings
(e.g. taper roller bearings) in dismantling, to
ensure correct reassembly. Never fit new rollers
in a used outer ring, always fit a complete new
bearing assembly.

INFORMATION JOINTS AND JOINT FACES
1.Always use correct gaskets where they are
specified.
2.Use jointing compound only when
recommended. Otherwise fit joints dry.
3.When jointing compound is used, apply in a thin
uniform film to metal surfaces; take great care to
prevent it from entering oilways, pipes or blind
tapped holes.
4.Remove all traces of old jointing materials prior
to reassembly. Do not use a tool which could
damage joint faces.
5.Inspect joint faces for scratches or burrs and
remove with a fine file or oil stone; do not allow
removed material or dirt to enter tapped holes or
enclosed parts.
6.Blow out any pipes, channels or crevices with
compressed air, fit new’O’rings or seals
displaced by air blast.FLEXIBLE HYDRAULIC PIPES, HOSES
1.Before removing any brake or power steering
hose, clean end fittings and area surrounding
them as thoroughly as possible.
2.Obtain appropriate plugs or caps before
detaching hose end fittings, so that ports can be
immediately covered to exclude dirt.
3.Clean hose externally and blow through with
airline. Examine carefully for cracks, separation
of plies, security of end fittings and external
damage. Reject any hose found faulty.
4.When refitting hose, ensure that no unnecessary
bends are introduced, and that hose is not
twisted before or during tightening of union nuts.
5.Containers for hydraulic fluid must be kept
absolutely clean.
6.Do not store brake fluid in an unsealed
container. It will absorb water, and fluid in this
condition would be dangerous to use due to a
lowering of its boiling point.
7.Do not allow brake fluid to be contaminated with
mineral oil, or use a container which has
previously contained mineral oil.
8.Do not re-use brake fluid bled from system.
9.Always use clean brake fluid to clean hydraulic
components.
10.Fit a cap to seal a hydraulic union and a plug to
its socket after removal to prevent ingress of dirt.
11.Absolute cleanliness must be observed with
hydraulic components at all times.
12.After any work on hydraulic systems, inspect
carefully for leaks underneath the vehicle while a
second operator applies maximum pressure to
the brakes (engine running) and operates the
steering.

DESCRIPTION AND OPERATION CYLINDER HEAD COMPONENTS
The cylinder head components are described below:
Cylinder head
The cylinder head is of aluminium construction. It is not possible to reface the cylinder head if it becomes worn or
damaged. An alloy camshaft carrier is bolted directly to the upper surface of the cylinder head. Two dowels are
included in the cylinder head upper face for correct location of the camshaft carrier.
The EU3 cylinder head has a single internal fuel rail for delivering fuel to the injectors and an external fuel pipe for
returning spill fuel back to the fuel connector block. Therefore, pre EU3 and EU3 cylinder heads are not
interchangeable.
CAUTION: The cylinder head incorporates drillings for the fuel injection system, any
contamination which enters these drillings could cause engine running problems or injector
failure. It is therefore, essential that absolute cleanliness is maintained when carrying out work on
the cylinder head.
The camshaft carrier and cylinder head assembly is attached to the cylinder block by twelve cylinder head
retaining bolts which pass through the camshaft carrier and the cylinder head to secure the assembly to the
cylinder block.
CAUTION: The valve heads, tips of the injectors and glow plugs protrude below the face of the
cylinder head and will be damaged if the cylinder head is stored face down.
The camshaft is located between the cylinder head and the camshaft carrier, and the bearing journals are line
bored between the two components to form a matched pair.
CAUTION: Always fit plugs to open connections to prevent contamination.
The valve guides and valve seat inserts are sintered components which are an interference fit to the cylinder
head. The cylinder head machining also provide the locations for the electronic unit injectors, glow plugs, hydraulic
lash adjusters, finger followers and low pressure fuel rail.
Cooling to the cylinder head is provided by coolant flow through a water jacket machined into the cylinder head.
Drillings through the block provide lubrication channels for pressurised oil supply to cylinder head components
such as the lash adjusters, finger followers, rocker arms and camshaft bearings.
A coolant outlet elbow is fitted to the front LH side of the cylinder head to allow flow of coolant from the cylinder
head back to the radiator. A metal gasket is used to seal the joint between the water outlet elbow and the cylinder
head. A coolant temperature sensor is located in a port in the side of the water outlet elbow for monitoring coolant
temperature.
A stub pipe is connected at the front RH side of the cylinder block above the timing cover which connects a pipe to
supply oil to the vacuum pump. The timing chain tensioner adjuster is screwed in a thread in the cylinder head at a
location on the front RH side of the engine below the oil feed port for the vacuum pump.
An access hole for the camshaft gear is included at the front of the cylinder head which is sealed with a plastic
plug and rubber’O’ring. A press-fit core plug for the chain chest is located on the front face of the cylinder head.
A press-fit core plug for the cylinder head water jacket is located at the rear of the cylinder head and a threaded
brass plug for the water jacket is located on the LH side of the cylinder head beneath the exhaust manifold
assembly.

DESCRIPTION AND OPERATION Fuel connector block
Type A - Non EU3 Models - Engine Serial No. Prefixes 10P to 14P
Type B - EU3 Models - Engine Serial No. Prefixes 15P to 19P
1.Fuel connector block assembly
2.Outlet stub pipe
3.Stub pipe - to fuel cooler4.Fuel temperature sensor
5.Fuel pressure regulator
6.Spill return fuel connection (EU3 models only)
A cast and machined aluminium alloy fuel connector block assembly is located at the rear RH side of the cylinder
head, attached by three flanged bolts. A metal gasket is used to seal the faces between the fuel connector block
and the cylinder head, which must be replaced every time the fuel connector block is removed.
CAUTION: The cylinder head incorporates drillings for the fuel injection system, any
contamination which enters these drillings could cause engine running problems or injector
failure. It is therefore, essential that absolute cleanliness is maintained when carrying out work on
the cylinder head.
CAUTION: The valve heads, tips of the injectors and glow plugs protrude below the face of the
cylinder head and will be damaged if the cylinder head is stored face down.
Camshaft carrier
The cast aluminium alloy camshaft carrier is bolted to the cylinder head by thirteen screws. The camshaft carrier
and cylinder head assembly is attached to the cylinder block by twelve cylinder head retaining bolts which pass
through the camshaft carrier and the cylinder head to secure the assembly to the cylinder block.
The carrier is machined together with the cylinder head to form a matched pair for carrying the camshaft.
Non-return valve
A non-return valve is located at the front, bottom LH side of the cylinder head. The non-return valve prevents oil
from draining from the lash adjusters and is an integral component within the cylinder head and is
non-serviceable.
