PREFACE
This manual describes the service procedures for the TNV series engines of indirect injection system
that have been certified by the US EPA, California ARB and/or the 97/68/EC Directive for industrial use.
Please use this manual for accurate, quick and safe servicing of the said engine. Since the
explanation in this manual assumes the standard type engine, the specifications and components may
partially be different from the engine installed on individual work equipment (power generator, pump,
compressor, etc.). Please also refer to the service manual for each work equipment for details.
The specifications and components may be subject to change for improvement of the engine quality
without notice. If any modification of the contents described herein becomes necessary, it will be
notified in the form of correction information each time.
SAFETY LABELS
Most accidents are caused by negligence of basic safety rules and precautions. For accident
prevention, it is important to avoid such causes before development to accidents.
Please read this manual carefully before starting repair or maintenance to fully
understand safety precautions and appropriate inspection and maintenance
procedures.
Attempting at a repair or maintenance job without sufficient knowledge may cause an unexpected
accident.
It is impossible to cover every possible danger in repair or maintenance in the manual. Sufficient
consideration for safety is required in addition to the matters marked
safety precautions in a repair or maintenance job not described in this manual, receive instructions
from a knowledgeable leader.
Safety marks used in this manual and their meanings are as follows:
DANGER-indicates an imminently hazardous situation, which,
if not avoided, WILL result in death or serious injury.
WARNING-indicates a potentially hazardous situation, which, if not
avoided, COULD result in death or serious injury.
CAUTION-indicates a potentially hazardous situation, which, if not
avoided, MAY result in minor or moderate injury.
. Especially for
NOTICE-indicates that if not observed, the product performance or quality may not be
guaranteed.
(1) SERVICE AREA
Safety Precautions
Sufficient Ventilation
Inhalation of exhaust fumes and dust particles may be hazardous to
ones health. Running engines welding, sanding, painting, and polishing
tasks should be only done in well ventilated areas.
Safe / Adequate Work Area
The service area should be clean, spacious, level and free from holes
in the floor, to prevent “slip” or “trip and fall” type accidents.
Bright, Safely Illuminated Area
The work area should be well lit or illuminated in a safe manner. For
work in enclosed or dark areas, a “drop cord” should be utilized. The
drop cord must have a wire cage to prevent bulb breakage and
possible ignition of flammable substances.
Safety Equipment
Fire extinguisher(s), first aid kit and eye wash / shower station should
be close at hand (or easily accessible) in case of an emergency.
(2) WORK – WEAR (GARMENTS
Safe Work Clothing
Appropriate safety wear (gloves, special shoes/boots, eye/ear
protection, head gear, harness’, clothing, etc.) should be used/worn to
match the task at hand. Avoid wearing jewelry, unbuttoned cuffs, ties
or loose fitting clothes around moving machinery. A serious accident
may occur if caught in moving/rotating machinery.
(3) TOOLS
Appropriate Lifting / Holding
When lifting an engine, use only a lifting device (crane, jack, etc.) with
sufficient lifting capacity. Do not overload the device. Use only a chain,
cable, or lifting strap as an attaching device. Do not use rope, serious
injury may result.
To hold or support an engine, secure the engine to a support stand, test
bed or test cart designed to carry the weight of the engine. Do not
overload this device, serious injury may result.
Never run an engine without being properly secured to an engine support
stand, test bed or test cart, serious injury may result.
Appropriate Tools
Always use tools that are designed for the task at hand. Incorrect
usage of tools may result in damage to the engine and or serious
personal injury.
(4) GENUINE PARTS and MATERIALS
Genuine Parts
Always use genuine YANMAR parts or YANMAR recommended parts
and goods. Damage to the engine, shortened engine life and or
personal injury may result.
(5) FASTENER TORQUE
Torqueing Fasteners
Always follow the torque values and procedures as designated in the
service manual. Incorrect values, procedures and or tools may cause
damage to the engine and or personal injury.
(6) Electrical
Short Circuits
Always disconnect the (-) Negative battery cable before working on the
electrical system. An accidental “short circuit” may cause damage,
fire and or personal injury. Remember to connect the (-) Negative
battery cable (back onto the battery) last.
Fasten the terminals tightly.
Charging Batteries
Charging wet celled batteries produces hydrogen gas. Hydrogen gas is
extremely explosive. Keep sparks, open flame and any other form of
ignition away. Explosion may occur causing severe personal injury.
Battery Electrolyte
Batteries contain sulfuric acid. Do NOT allow it to come in contact
with clothing, skin and or eyes, severe burns will result.
(7) WASTE MANAGEMENT
Observe the following instructions with regard to hazardous waste
disposal. Negligence of these will have a serious impact on
environmental pollution concerns.
1)
Waste fluids such as lube oil, fuel and coolant shall be carefully put
into separate sealed containers and disposed of properly.
2)
Do NOT dispose of waste materials irresponsibly by dumping them
into the sewer, overland or into natural waterways.
3)
Waste materials such as oil, fuel, coolant, solvents, filter elements
and batteries, must be disposed of properly according to local
ordinances. Consult the local authorities or reclamation facility.
(8) FURTHER PRECAUTIONS
Fueling / Refueling
Keep sparks, open flames or any other form of ignition (match,
cigarette, etc.) away when fueling/refueling the unit. Fire and or an
explosion may result.
Hot Surfaces.
Do NOT touch the engine (or any of its components) during running or
shortly after shutting it down. Scalding / serious burns may result. Allow
the engine to cool down before attempting to approach the unit.
Rotating Parts
Be careful around moving/rotating parts. Loose clothing, jewelry, ties or
tools may become entangled causing damage to the engine and or
severe personal injury.
Preventing burns from scalding
1)
Never open the radiator filler cap shortly after shutting the engine
down.
Steam and hot water will spurt out and seriously burn you. Allow
the engine to cool down before attempt to open the filler cap.
2)
Securely tighten the filler cap after checking the radiator.
Steam can spurt out during engine running, if tightening loose.
Precautions for Service Work
(1) Precautions for Safety

1.3 Fuel Oil, Lubricating Oil and Coolant Water
1.3.1 Fuel oil
IMPORTANT:
Only use the recommended fuel to obtain the best engine performance and prevent damage of parts,
also prevent air pollution.
(1) Selection of fuel oil
Use the following diesel fuels for best engine performance:
BS 2869 A1 or A2
Fuels equivalent to Japanese Industrial Standard, JIS. No. K2204-2
Fuel cetane number should be 45 or greater
(2) Fuel handling
Water and dust in the fuel oil can cause operation
failure. Use containers which are clean inside to
store fuel oil. Store the containers away from
rain water and dust.
Before supplying fuel, let the fuel container rest for
several hours so that water and dust in the fuel
are deposited on the bottom. Pump up only the
clean fuel.
(3) Fuel tank
Be sure to attach a drain cock, precipitation trap and
primary strainer to the fuel tank as shown illustration
right.
14
1.3.2 Lubricating oil
IMPORTANT:
Use of other than the specified engine oil may cause inner parts seizure or early wear, leading to
shorten the engine service life.
(1) Selection of engine lube oil
Use the following engine oil
API classification CD or CF
(Standards of America Petroleum Institute)
SAE viscosity
(Standard of Society of Automotive Engineering)
Engine oil with 10W30 or 15W40 can be used
throughout the year.
(Refer to the right figure.)
(2) Handling of engine oil
Carefully store and handle the oil so as to prevent
dust or dirt entrance. When supplying the oil,
pay attention and clean around the filler port.
Do not mix different types of oil as it may
adversely affect the lubricating performance.

1. General
1.3.3 Coolant water
Use clean soft water and be sure to add the Long Life Coolant Antifreeze (LLC) in order to prevent rust
built up and freezing. If there is any doubt over the water guality, distilled water or pre-mixed coolant
should be used.
The coolants / antifreezes, which are good performance for example, are shown below.
TEXACO LONG LIFE COOLANT ANTIFREEZE, both standard and pre-mixed.
Product codes 7997 and 7998
HAVOLINE EXTENDED LIFE ANTIFREEZE / COOLANT
Product code 7994
IMPORTANT:
Be sure to add Long Life Coolant Antifreeze(LLC) to soft water. In cold season, the LLC is
especially important. Without LLC, cooling performance will decrease due to scale and rust in the
coolant water line. Without LLC, coolant water will freeze and expand to break the cooling line.
Be sure to use the mixing ratios specified by the LLC manufacturer for your temperature range.
Do not mix different types (brand) of LLC, chemical reactions may make the LLC useless and
engine trouble could result.
Replace the coolant water every once a year.
When handling Long Life Coolant Antifreeze, wear protective rubber
gloves not to touch it. If LLC gets eyes or skin, wash with clean water
at once.
