Introduction
The valve train system opens and closes the
valves with correct timing in relation to the piston
movements.
Each push rod has one end in a valve tappet and the
other end under a rocker arm, or as applicable. The
adjusting screw has a ball shaped end that locates in
the push rod. The adjusting screw is used for setting
the valve clearance.
The valves extend through the cylinder head. There
are no sleeves or valve guides in the cylinder head.
The valves are made from a special metal to provide
a long service life. Damaged or worn valves cannot
be lapped or reground and must be replaced with
new ones. Each valve stem has an oil seal.
The Valve seat inserts are pressed into the cylinder
head. The seat inserts are also made from a special
metal to provide for a long service life. Damaged or
worn seat inserts can be removed and replaced with
new ones.

Operation
The camshaft drive gear is driven by the crankshaft
gear at half the speed of the crankshaft. Camshaft
lobes, two for each cylinder, (operating exhaust and
inlet valves) actuate the valve tappets.
When the camshaft rotates the cam lobes act on the
tappets. The push rods act on the rockers which pivot
on the camshaft, depressing two valves at the same
time via the bridge piece.
The screw is self locking in the rocker by means of
a tapered thread. Wave washers act like springs to
keep the rockers in their correct positions along the
camshaft and prevent them contacting one another.
The rockers incorporate a swivel tip to ensure
alignment with the bridge piece. This prevents
excessive wear.
Each valve has a compression spring. The function
of the spring is to close the valve and at the same
time return the rocker arm and push rod to ensure
that the tappets follow the camshaft lobes. The spring
is located on the valve stem by a retainer and split
collets.

Engine Position
The engine needs to be set to two different positions
to measure and adjust all of the valves. The graphics
show which valves are applicable at which engine
position.
1. Make sure that the engine is safe to work on. If
the engine has been running, let it cool before
you start the service work.
2. Get access to the engine.
3. Remove the tappet covers. Refer to (PIL 15-42).
4. Put the indicator pins into the holes inside the
tappet adjusters for cylinder number 4. Make
sure that the pins do not fall into the engine.
5. Use the crankshaft turning tool to turn the engine
crankshaft clockwise. Stop turning the crankshaft
when one indicator pin starts to move up after the
other pin has moved down. This is the position
where the exhaust valve is almost closed and the
inlet valve is just starting to open.

Valve Clearances
The procedure describes how to measure and,
if necessary, adjust one valve clearance. The
procedure for all the valves is the same. Do the
procedure for the correct valves at each of the two
engine positions. Remember you must remove the
valve clearance service tools before you turn the
engine crankshaft.
Important: The engine must be cold before you
measure or adjust the valve clearances.
1. Install the adaptor plate in the correct position on
the rocker cover using the screws A.
2. Make sure that the crankshaft is in the correct
position.
3. Put the adaptor sleeve on the correct valve
tappet adjuster screw.
4. Push the lock bar into the correct valve tappet
adjuster screw.
5. Tighten the lock bar by turning it with your hand.
6. Assemble the DTI support and DTI.
7. Push and then pull the lock bar in the direction of
the arrows X and Y. Do this until you are sure that
the lock bar is correctly installed and oil is moved
away from the cam follower and push rod.
8. Important: Apply a side force on the lock bar
at the same time as pushing and pulling. This
prevents the rocker moving along the rocker
shaft and giving a false reading on the DTI. Apply
a force to the left on the exhaust valve tappets
and to the right on the inlet valve tappets.

necessary:
11.1. Turn the tappet adjuster using an open
ended spanner on the adaptor sleeve.
Turn the sleeve clockwise to reduce
the clearance and counterclockwise to
increase the clearance.
11.2. Important: The tappet adjusters are set in
position by thread friction with the rockers.
Make sure that the torque to turn the
tappet adjusters is more than the minimum
necessary. If any of the adjusters show a
lower torque value then the adjuster and
its related rocker must be replaced.

Introduction
The piston is acted upon by the pressure of the
expanding combustion gases in the combustion
chamber space at the top of the cylinder. This force
then acts downwards through the connecting rod and
on to the crankshaft.
The pistons are cast from aluminium alloys for
increased strength and improved fatigue life.
The connecting rod is attached to the piston by a
swivelling piston pin. This pin is mounted within the
piston, The pin itself is of hardened steel and is fixed
in the piston, but free to move in the connecting rod.
The pins are prevented from moving sideways and
the ends of the pin digging into the cylinder wall by
circlips.

Operation
The groove around the diameter of the upper main
bearing shells allows oil transfer to an oil jet located
in the crankcase bearing saddle. Jets are installed at
the main bearing positions.
The jets spray oil directly to the under side of the
pistons effectively transferring heat away from the
top of the pistons. Oil spray also enters the small end
bearing bushes via a feed hole on the top of each
connecting rod.
Note: On turbocharged engines additional J-jets are
installed. Oilways connect the J-shaped jets fixed to
the crankcase at the underside of each cylinder bore.

the piston ring grooves to confirm they are within
service limits.
Refer to: PIL 15-36-00.
2. Check the piston pin for signs of damage and
excessive wear. Measure the pin diameter to
confirm it is within service limits. Refer to Piston.
Refer to: PIL 15-36-00.
The connecting rod small end bearing bush is not
renewable. If the small end bearing bush is damaged
or worn the connecting rod must be renewed as a
complete assembly.

Piston Height Measurement Above
Cylinder Block- DTI Method
In the event of sufficient liquid entering the engine, a
hydraulic lock can occur. This may result in bending
of one or more of the connecting rods. Bending of the
connecting rod(s) can occur even when the engine is
cranked by the starter motor.
Bending of the connecting rod may be very slight and
can be checked by carrying out this procedure prior
to a full strip down:
1. With the cylinder head removed, make sure the
surface of the engine block and piston are clean.
2. Zero a DTI (Dial Test Indicator) on the top face
of the cylinder block adjacent to the area on the
piston to be measured. The aim of the procedure
is to use the DTI to take a measurement across 2
locations on the piston that are on the axis of the
gudgeon pin. This will be towards the front and
rear of the engine.
3. Rotate the engine and bring the piston up until
it is 3mm below the engine block face. Carefully
reposition the zeroed DTI above the area of the
piston to be measured.
4. Rotate the engine to bring the piston up to
exactly TDC (Top Dead Centre) and record the
measurement at position 1.
5. Repeat steps 2 to 4 for position 2.
6. Calculate the average of the 2 readings to give
a figure of the piston height above the cylinder
block.
7. Compare the reading obtained to the technical
data.
Refer to: PIL 15-36-00.
7.1. If the reading obtained is lower than zero,
the connecting rod may be bent.
7.2. If the reading obtained is equal to the range
stated in technical data, the connecting rod
is not bent.
8. Repeat steps 2 to 7 to check all connecting rods/
pistons.
9. If any connecting rods are bent, strip the engine
and check for further damage.
10. If the engine is serviceable, any connecting rod
that is bent must be replaced.

Piston Height Measurement Above
Cylinder Block- Straight Edge Method
If a DTI is not available, a calibrated straight
edge may be used to take a measurement. The
measurement will be less accurate.
1. With the cylinder head removed, make sure the
surface of the engine block and piston are clean.
2. Rotate the engine until the piston to be measured
is at TDC.
3. Position the straight edge on top of the piston
along the axis of the gudgeon pin.
4. Use feeler gauges to measure the gap between
the cylinder block face and underside of the
straight edge on both sides, position 1 and
position 2.
5. Calculate the average of the 2 readings to give
a figure of the piston height above the cylinder
block.
5.1. If the reading obtained is lower than zero,
the connecting rod may be bent.
5.2. If the reading obtained is equal to the range
stated in technical data, the connecting rod
is not bent.
Refer to: PIL 15-36-00.
6. Repeat steps 1 to 5.2 to check all connecting
rods/pistons.

Remove
The piston and connecting rod assemblies are
removed through the top of the crankcase.
1. Use a suitable scraper and wire wool to clean off
the carbon deposits from around the top of the
cylinder bore. Take care not to scratch or damage
the cylinder bore.
2. Use a hammer and a short length of wood to
tap the piston from the connecting rod side. Take
care not to scratch or damage the cylinder bore
or the connecting rod bearing surface.
Install
1. The installation procedure is the opposite of the
removal procedure. Additionally do the following
steps.
2. Make sure that all items are clean and free from
damage and corrosion.
3. If the upper big end bearing shell has been
removed replace it. Refer to (PIL 15-33-06).
4. Lubricate the cylinder bore with clean engine oil.
5. Use a suitable compressor tool to compress the
piston rings.
6. Insert the piston and connecting rod assembly
into the cylinder bore, make sure that the longest
side of the connecting rod is on the exhaust side
of the crankcase. Take care not to damage the
cooling jets when you guide the connecting rod
down the cylinder bore and over the crank pin
diameter.
After Installation
1. Install the big end bearing caps. Refer to (PIL
15-33-06).

Disassemble and Assemble
Dismantle
1. Clamp the connecting rod in a vice. Take care not
to damage the connecting rod.
2. It is recommended that the piston rings are
renewed. If they are to be reused, label the
rings to ensure they are installed in the correct
positions and the correct way up on assembly.
Carefully remove the piston rings from the piston.
To avoid damage or distortion to the rings, use a
suitable piston ring expander tool. Note that the
oil control ring is installed with a spiral wire. Pull
the wire apart and remove it.
3. Remove the circlips and push out the piston pin.
4. Use a suitable cleaning agent, clean the carbon
deposits from the piston.

Assemble
1. The assembly procedure is the opposite of
the disassemble procedure. Additionally do the
following steps.
2. Make sure that all items are clean and free from
damage and corrosion.
3. Lubricate the piston pin with clean engine oil.
Assemble the connecting rod to the piston and
insert the piston pin. Make sure that the long side
of the connecting rod is on the same side as the
internal cast boss in the piston.
4. Install new circlips. Make sure that they are
installed correctly in the groove in the piston.
5. Lubricate the piston with clean engine oil. Install
the piston rings to the piston in sequence as
follows:
5.1. Install the spiral wire for the oil control ring
in the bottom groove and locate the locking
wire inside both ends of the spiral as shown.
