Operation
When the camshaft lobe raises the push-rod, the
push-rod pushes the rocker arm up. Due to this the
rocker arm presses down on the valve stem to open
the valve. When the rocker arm returns due to the
camshafts rotation, the valve spring closes the valve.
Lubrication
Oil is fed from the main gallery through a drilling
which passes up through the crankcase and cylinder
head to a small transfer gallery under the rocker
shaft pedestal. The oversize rocker shaft fixing bolt
hole allows oil to pass into a drilling in the centre of
the rocker shaft. Further cross drillings transfer oil
to each of the rocker pivot bushes. A cross drilling
in each rocker transfers oil to the top of the rocker
where it flows by gravity along a groove to the rocker
tip.

Operation
Hydraulic Tappet
The operating principle of the hydraulic tappet is
based on the incompressibility of the liquid and on
controlled leakage between the piston and the tappet
body.
A constant supply of pressurised oil is provided to the
low pressure chamber. The pressurized oil can only
get the access to the high pressure chamber through
the unidirectional (non-return) valve.
The high pressure chamber is filled when the rocker
arm is on the base radius of the cam and the spring
holds the piston against the valve stem preventing
from system play as well as vibration and noise.
Due to the spring movement, the tappet extends.
This creates a small pressure decrease in the high
pressure chamber to open the non-return valve. Oil
is then transferred from the low pressure chamber
to the high pressure chamber to restore the proper
amount of oil required to eliminate any play in the
valves.
Difficult Operating Conditions
For proper operation of the hydraulic tappets it is
essential that the low pressure chamber of the piston
is always full of oil.
In some conditions this may not occur (due to the
fact that oil leaks away when the engine is switched
off, which can also partially drain the tappets): this
situation will result in play that will occur with a typical
noise similar to ticking, not to be confused with the
normal ticking of the injectors.
When the engine is cold, the tappet filling time could
be very long if the oil used is not suitable for the
specific environmental conditions.
If the engine is very hot or at idle speed, oil pressure
may be low, and small air bubbles could form in
the circuit. Because of this, the lubricant becomes
compressible, thus compressing the tappet slightly
and producing valve play which is responsible for the
ticking sound.
In all cases, the ticking should not last too long (max
5 minutes) if not, the problem will surely be due to
the poor quality of the oil, wear or impurities that,
transported by the oil, can infiltrate between the ball
valve and its seat inside the piston This affects the
operation of the tappet itself. In these cases you must
replace the oil or the hydraulic tappets.
Continuous ticking or abnormal sound for prolonged
periods is a symptom of a possible malfunction, and
requires the removal and replacement of oil and
hydraulic tappets.

Check (Condition)
Tappets and Tappet Housing Check
1. Put the tappet on a V-notch surface plate.
2. Measure the following dimensions of the tappet
and tappet housing.
2.1. Perpendicularity of the base with a dial
gauge.
2.2. Length of the tappet to assess the wear.
2.3. Diameter of the tappet housing with an
internal dial gauge.
3. Make sure that you measure the housing
diameter at two locations and the difference
between the two values should not be more than
0.02mm.
4. Measure the clearance between the tappet and
the tappet housing from the values derived in
step 2.
5. Make sure that all the values are within the
allowable limits.
Refer to: PIL 15-42-21.
Calibrate
Tappets Dimensions
Use a surface plate and a dial gauge as shown.
Check the perpendicularity of the plate, making the
tappet rotate in the direction of the arrow. With a
gauge, check the length of the tappet to assess wear.
The values measured must be within tolerances.
Refer to: PIL 15-42-21.

contains harmful contaminants which can cause skin
cancer. Do not handle used engine oil more than
necessary. Always use barrier cream or wear gloves
to prevent skin contact. Wash skin contaminated with
oil thoroughly in warm soapy water. Do not use petrol,
diesel fuel or paraffin to clean your skin.
CAUTION! It is illegal to pollute drains, sewers
or the ground. Clean up all spilt fluids and/or
lubricants. Used fluids and/or lubricants, filters and
contaminated materials must be disposed of in
accordance with local regulations. Use authorised
waste disposal sites.
CAUTION! Oil will gush from the hole when the drain

Introduction
The timing gears are located inside a casing at the
front end of the engine.
The engine must be timed so that the camshaft
operates the valves at the correct time relative to the
crankshaft position.
Valve timing is achieved by ensuring that the
camshaft drive gear is meshed to the crankshaft gear
at their correct angular positions, Refer to Engine-
General, Operation, The Four Stroke Cycle for more
information about valve timing.
