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 hydraulic tappet and
the other end under a rocker arm.
The hydraulic tappet automatically adjusts the
clearance between the rocker and push rods.
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 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.

Check (Condition)
1. Check the piston for signs of damage and

diameter, piston pin bore and the clearance in
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

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.

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.

2. 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.
3. 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.
Before Installation

to damage the cooling jets when you guide the
connecting rod down the cylinder bore and over
the crank pin diameter.
7. Install the big end bearing cap. Make sure that
it is orientated correctly, the orientation mark

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 short
side of the connecting rod is on the same side as
the cut out 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.
Using a piston ring expander tool to install
the oil control ring in the bottom groove and
locate the locking wire inside both ends of
the spiral as shown. Make sure that the
ring gap is positioned 180° to the locking
wire. The correct ring orientation can also
be determined from the profile shape of the
ring.
Refer to: PIL 15-36-00.
5.2. Install the No.2 compression ring into the
middle groove. New rings have a reference
number etched on one face. Make sure
that this face is installed uppermost in the
piston groove. The correct ring orientation
can also be determined from the profile
shape of the ring.
Refer to: PIL 15-36-00.
5.3. Install the No.1 compression ring into the
top groove. New rings have a reference
number etched on one face. Make sure
that this face is installed uppermost in the
piston groove. The correct ring orientation
can also be determined from the profile
shape of the ring.
Refer to: PIL 15-36-00.
6. Rotate the piston rings so that the ring gaps are
120° apart as shown.

Introduction
Gas sealing inside the piston is achieved by the use
of piston rings. The rings are loosely installed into
grooves in the piston. The rings are split at a point in
the rim, to allow them to press against the cylinder
with a light spring pressure.
Two types of ring are used:
- Upper rings have solid faces and provide gas
sealing
- Lower rings have narrow edges and have a U-
shaped profile, to act as oil scrapers.
