00. Contents, Instructions, Terminology
00.1 Contents of the Manual
This Manual contains data and instructions for operation and mainte-
nance of the engine as well as instruction for handling, personal
protection and first aid when fuel-, lubricating oils and cooling water
additives are handled during normal operation and maintenance work.
Basic general knowledge has not been entered. Consequently,
it is assumed that the engine operation and maintenance staff is
well informed of the care of diesel engines.
Wärtsilä reserves for itself the right to minor alterations and
improvements owing to engine development without being
obliged to enter the corresponding changes in this Manual.
The diesel engines will be equipped as agreed upon in the sales
documents. No claim can be made on the basis of this Manual as
here are described also components not included in every delivery.
The system diagram plans (fuel, oil, cooling etc.) are just indica-
tive and thus do not cover all installations. See installation
specific system drawings for more details.
Exact engine build-up in all details is defined by the specification
number on the name plate located on the engine. In all correspon-
dence or when ordering spare parts, be careful to state
engine type, specification number and engine number.
This Manual is supplemented by the Spare Parts Catalogue
including sectional drawings or exterior views of all components
(partial assemblies).
00.2 General rules
1 Read the corresponding item carefully in this Manual
before any steps are taken.
2 Keep an engine log book for every engine.
3 Observe the utmost cleanliness and order at all main-
tenance work.
4 Before dismantling, check that all systems concerned are
drained or the pressure released. After dismantling, immedi-
ately cover holes for lubricating oil, fuel oil and air with tape,
plugs, clean cloth or the like.

5 When replacing a worn-out or damaged part provided
with an identification mark stating cylinder or bearing num-
ber, mark the new part with the same number on the same
spot. Every exchange should be entered in the engine log and
the reason should be clearly stated.
6 After reassembling, check that all screws and nuts are
tightened and locked, if necessary.
7 Check that all shields and covers are fully functional
and in place.
Note! Predictive maintenance is important when it comes to fire
protection. Regular inspection of fuel oil lines, lubricating oil
lines and connections must be done.
00.3 Terminology
The most important terms used in this manual are defined as
follows, see also Fig 00-1:
Operating side. The longitudinal side of the engine where the
operating devices are located (start and stop, instrument panel,
speed governor).
Rear side. The longitudinal side of the engine opposite the
manoeuvering side.
Driving end. The end of the engine where the flywheel is located.
Free end. The end opposite the driving end.
Designation of cylinders. According to ISO 1204 and DIN 6265
the designation of cylinders begins at the driving end. In a
V-engine the cylinders in the left bank, seen from the driving end,
are termed A1, A2 etc. and in the right bank B1, B2 etc., see below:

Designation of bearings.
·Main bearings. The shield bearing (nearest the flywheel) is No.
0, the first standard main bearing is No. 1, the second No. 2 etc.
·The thrust bearing rails are located at the shield bearing.
The outer rails close to the flywheel are marked with 00 and
the inner rails with 0.
·The camshaft bearings are designated as the main bearings,
the thrust bearing bushes being designated 00 (outer) and 0.
·Camshaft gear bearings. The bearing bushes are designated
00 (outer) and 0.
·Upper and lower bearings shells. In bearings where both the
shells are identical, the upper one is marked with “UP”.
Designation of bearings
Operating side and rear side. Details located at the operating
side may be marked with “M” (Manoeuvering) and correspond-
ingly “B” for the back of the engine (B-bank on a V-engine).
Clockwise rotating engine. When looking at the engine from
the driving end the shaft rotates clockwise.
Counter-clockwise rotating engine. When looking at the
engine from the driving end the shaft rotates counter-clockwise.
Bottom dead centre, abbreviated BDC, is the bottom turning
point of the piston in the cylinder.
Top dead centre, abbreviated TDC, is the top turning point of
the piston in the cylinder. TDC for every cylinder is marked on
the graduation of the flywheel. During a complete working cycle,
comprising in a four-stroke engine two crankshaft rotations, the
piston reaches TDC twice:

a) For the first time when the exhaust stroke of the previous
working cycle ends and the suction stroke of the following one
begins. Exhaust valves as well as inlet valves are then somewhat
open and scavenging takes place. If the crankshaft is turned to
and fro near this TDC, both exhaust and inlet valves will move,
a fact that indicates that the crankshaft is near the position which
can be named TDC at scavenging.
b) The second time is after the compression stroke and before the
working stroke. Slightly before this TDC the fuel injection takes
place (on an engine in operation) and this TDC can therefore be
defined TDC at firing. Characteristic is that all valves are closed
and do not move if the crankshaft is turned. When watching the
camshaft and the injection pump it is possible to note that the
pump tappet roller is on the lifting side of the fuel cam.
Marking of the flywheel. The flywheel is divided in 360°, starting
from TDC at firing for cylinder 1. TDC at firing for every cylinder
is marked on the flywheel. There is a common marking for the
cylinders in engines with even cylinder numbers, one cylinder is
at TDC at firing and the other is at TDC at scavenging. There are
separate scales for A- and B-bank in a V-engine. See also the firing
order in chapter 01. Firing interval, in crank angles, can be
determined by dividing 720° with the number of cylinder.
Example of reading the flywheel
Example: On a 12V32 engine, the fuel timing is read to 10° for
cylinder A2 when the flywheel is in the position shown in the above
figure.

00B. Welding Precautions
00B.1 General Precautions
00B.1.1 Welding safety
Before start welding, it is important to read welding safety instruc-
tions and that the welder is instructed on its safe use by a qualified
teacher or welder.
00B.1.1.1 Hazards and precautions
Electrical shock can kill
·Insulate welder from workpiece and ground using dry insulation.
Rubber mat or dry wood.
·Wear dry, hole-free gloves. (Change as necessary to keep dry.)
·Do not touch electrically “hot” parts or electrode with bare skin or
wet clothing.
·If wet area and welder cannot be insulated from workpiece with dry
insulation, use a semiautomatic, constant-voltage welder or stick
welder with voltage reducing device.
·Keep electrode holder and cable insulation in good condition. Do not
use if insulation is damaged or missing.
Fumes and gases can be dangerous
·Use ventilation or exhaust to keep air breathing zone clear, comfort-
able.
·Use helmet and positioning of head to minimize fume in breathing
zone.
·Read warnings on electrode container and material safety data
sheet (MSDS) for electrode.
·Provide additional ventilation/exhaust where special ventilation re-
quirements exist.
·Use special care when welding in a confined area.
·Do not weld unless ventilation is adequate.
Welding sparks can cause fire or explosion
·Do not weld on containers which have held combustible materials.
Check before welding.
·Remove flammable materials from welding area or shield from
sparks, heat.
·Keep a fire watch in area during and after welding.
·Keep a fire extinguisher in the welding area.
·Wear fire retardant clothing and hat. Use earplugs when welding
overhead.
200640 Welding Precautions Appendix B
00 - 1

Arc rays can burn eyes and skin
·Select a filter lens which is comfortable for you while welding.
·Always use helmet when welding.
·Provide non-flammable shielding to protect others.
·Wear clothing which protects skin while welding
Confined space
·Carefully evaluate adequacy of ventilation especially where elec-
trode requires special ventilation or where gas may displace breath-
ing air.
·If basic electric shock precautions cannot be followed to insulate
welder from work and electrode, use semiautomatic, constant-volt-
age equipment with cold electrode or stick welder with voltage
reducing device.
·Provide welder helper and method of welder retrieval from outside
enclosure.
General work area hazards
·Keep cables, materials, tools neatly organized.
·Connect work cable as close as possible to area where welding is
being performed. Do not allow alternate circuits through scaffold
cables, hoist chains, or ground leads.
·Use only double insulated or properly grounded equipment.
·Always disconnect power to equipment before servicing.
Gas cylinders
·Never touch cylinder with the electrode.
·Keep cylinder upright and chained to support
Appendix B Welding Precautions 200640
00 - 2

00B.1.2 Main principles:
·Prevent uncontrolled current loops
·Prevent radiation
·Prevent sparkles flying around
·If convenient, disconnect all global signals like power supply, data
communication etc.
00B.1.2.1 Preventing uncontrolled current loops
Welding current path must always be checked, there should be a
straight route from the welding point back to the return connection
of the welding apparatus.
The main current is always going where it meets the lowest resis-
tance, in certain cases the return current can therefore go via
grounding wires and electronics in the control system.
To avoid this, the distance between the welding point and the return
connection clamp of the welding apparatus should always be
shortest possible and without electronic components in the return-
ing loop path.
Attention must be paid to the connectivity of the return connection
clamp, a bad contact might also cause sparkles and radiation.
00B.1.2.2 Preventing Radiation
The welding current and the arc is emitting a wide spectrum of
electromagnetic radiation. This might cause damages on sensitive
electronic equipment.
To avoid these damages all cabinets and terminal boxes must be
kept closed during the welding. Sensitive equipment can also be
protected by means of shielding with a conductive metal plate.
Also avoid having the cables of the welding apparatus going in
parallel with wires and cables in the control system. The high welding
current is easily inducting secondary currents in other conductive
materials.
00B.1.2.3 Preventing damage due to sparkles
Welding produces sparks. Few materials withstand the heat from
these sparkles. Therefore all cabinets and terminal boxes should be
kept closed during the welding. Sensors, actuators, cables and
other equipment on the engine must be properly protected.
Sparkles can also be a problem after they have cooled down, i.e.
causing short circuits, sealing problems etc.
