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.

Before Removal
1. This procedure requires service parts. Make
sure you have obtained the correct service parts
before you start. Refer to Parts Catalogue.
2. 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.
3. Get access to the engine.
4. Remove the cylinder head assembly.
Refer to: PIL 15-06-00.
5. Measure the valve recession with a suitable DTI
(Dial Test Indicator). Clean the carbon deposits
from a small area of the valve heads for location
of the DTI probe. If the valve recession is outside
the serviceable limits, it is advisable to obtain a
new or reconditioned cylinder head assembly.
Refer to: PIL 15-06-00.
6. To aid removal and Installation, use a wooden
valve stand to retain the valves after removal.
Add labels to make sure that the valves are
correctly replaced.

4. When removing, note the respective position of
each valve. Use a suitable valve stand to keep
the valves together and identify them with their
respective cylinder. The exhaust valves have
smaller diameter heads.
5. Remove the valve stem seals. Discard the seals.

Inspection
1. Carefully clean the carbon deposits from the
valves, take care not to damage the valve seats.
2. Check that the valves and valve seats are not
cracked, burnt or damaged.
3. Check the valve stems and valve guides for wear.
Refer to: PIL 15-30-00.
If there is evidence of wear or damage to the valves,
guides or seats, it is advisable to obtain a new or
reconditioned cylinder head assembly.
Before Installation
1. Position the cylinder head upside down in a
suitable jig or fixture.
2. Make sure that all items are clean and free from
damage and corrosion.
3. Install the injectors into the cylinder head to
do a trial check of the nozzle protrusion. Note
the relative positions for the injectors, and then
remove the injectors for installation at a later
stage.
Installation
1. The installation procedure is the opposite of the
removal procedure. Additionally do the following
steps.
2. Install the new valve stem seals as shown. Use
the installation tool to avoid damaging the seals.
Pre-assemble the seal into the tool. Locate the
tool over the valve guide and gently press the
seal into place. Lubricate the seal with P80 fluid.
Special Tool: Valve Stem Seal Installation Tool
(430 Engine) (Qty.: 1)
3. With the cylinder head on its side, insert the
inlet valves and exhaust valves as shown. Make
sure that the valves are installed in the correct
positions. Lubricate the valve stems with clean
engine oil before assembly. Carefully push the
end of the valve stem through the stem seals.
4. Install the valve springs on to the valve stems,
together with a retainer.
4.1. Make sure that the valve springs are
orientated correctly, the white painted end
of the valve spring must go at the top.
5. Use the spring compressor tool to compress
each valve spring and insert the collets. Make
sure that the collets are correctly seated in the
valve stem grooves before you remove the spring
compressor tool.
After Installation
1. Pop the valves by tapping the valve stems in turn
using a rubber mallet.

2. 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.
3. Get access to the engine.
4. Disconnect and remove the fuel pipes from the
injectors. Refer to (PIL 18-96).
5. Remove the rocker cover. Refer to (PIL 15-42).
6. Remove the fuel injectors. Refer to (PIL 18-18).

The connecting rod and the big-end bearing cap
have been fracture split and must be kept together
as a set. Care must be taken to avoid contamination
and or damage to the fracture split surfaces.
Remove
1. It is recommended that the big-end bearing caps
are removed in pairs, cylinders 1 and 4 and
cylinders 2 and 3. Rotate the crankshaft so that
