03-M Series, WSM SAFETY INSTRUCTIONS
SAFETY STARTING
• Do not start the engine by shorting across starter
terminals or bypassing the safety start switch.
• Unauthorized modifications to the engine may impair
the function and / or safety and affect engine life.
SAFETY WORKING
• Do not work on the machine while under the influence
of alcohol, medication, or other substances or while
fatigued.
• Wear close fitting clothing and safety equipment
appropriate to the job.
• Use tools appropriate to the work. Makeshift tools,
parts, and procedures are not recommended.
• When servicing is performed together by two or more
persons, take care to perform all work safely.
• Do not touch the rotating or hot parts while the engine
is running.
• Never remove the radiator cap while the engine is
running, or immediately after stopping. Otherwise, hot
water will spout out from radiator. Only remove
radiator cap when cool enough to touch with bare
hands. Slowly loosen the cap to first stop to relieve
pressure before removing completely.
• Escaping fluid (fuel or hydraulic oil) under pressure
can penetrate the skin causing serious injury. Relieve
pressure before disconnecting hydraulic or fuel lines.
Tighten all connections before applying pressure.
• Wear a suitable hearing protective device such as
earmuffs or earplugs to protect against objectionable
or uncomfortable loud noises.
AVOID FIRES
• Fuel is extremely flammable and explosive under
certain conditions. Do not smoke or allow flames or
sparks in your working area.
• To avoid sparks from an accidental short circuit,
always disconnect the battery negative cable first and
connect it last.
• Battery gas can explode. Keep sparks and open
flame away from the top of battery, especially when
charging the battery.
• Make sure that no fuel has been spilled on the engine.

SAFETY INSTRUCTIONS
03-M Series, WSM
VENTILATE WORK AREA
• If the engine must be running to do some work, make
sure the area is well ventilated. Never run the engine
in a closed area. The exhaust gas contains poisonous
carbon monoxide.
DISPOSE OF FLUIDS PROPERLY
• Do not pour fluids into the ground, down a drain, or
into a stream, pond, or lake. Observe relevant
environmental protection regulations when disposing
of oil, fuel, coolant, electrolyte and other harmful
waste.
PREVENT ACID BURNS
• Sulfuric acid in battery electrolyte is poisonous. It is
strong enough to burn skin, clothing and cause
blindness if splashed into eyes. Keep electrolyte
away from eyes, hands and clothing. If you spill
electrolyte on yourself, flush with water, and get
medical attention immediately.
PREPARE FOR EMERGENCIES
• Keep a first aid kit and fire extinguisher handy at all
times.
• Keep emergency numbers for doctors, ambulance
service, hospital and fire department near your
telephone.

DIESEL ENGINE
03-M Series, WSM
1. ENGINE BODY
[1] HOLLOW CORE
The cylinder block has a hollow core (1) already cast
inside the cylinder-to-cylinder water jacket.
In this core, there is a pair of vertical cooling
passages (right and left) as well as multiple horizontal
cooling channels that interconnect these cooling
passages. This design allows smoother cooling water
flow through the cylinder block, which cools down a wider
range between the cylinders more effectively.
W1013048
[2] PISTON
Piston’s skirt is coated with molybdenum
disulfied+, which reduces the piston slap noise and
thus the entire operating noise.
+Molybdenum disulfide (MoS2)
The molybdenum disulfide (1) serves as a solid
lubricant, like a Graphite or Teflon. This material helps
resist metal wears even with little lube oil.
W1013114
[3] BUILT-IN DYNAMIC BALANCER (BALANCER MODEL ONLY)
Engine are sure to vibrate by piston’s reciprocation.
Theoretically, three-cylinder engines are much less
prone to cause vibration than four-cylinder ones (second
inertia, etc.). However, any engine has many moving
parts in addition to its pistons and cannot be completely
free from vibration.
The four cylinders engine V2203 and V2403 can be
fitted with balance weight on crankcase to absorb the
second inertia mentioned above and reduce vibration.
This engine is internally provide with two balancers
(1), one at the suction side and the other at the exhaust
side.

[4] HALF-FLOATING HEAD COVER
The rubber packing (2) is fitted in to maintain the
cylinder head cover (1) 0.5 mm (0.02 in.) or so off the
cylinder head (1). This arrangement helps reduce noise
coming from the cylinder head.

2. COOLING SYSTEM
[1] BOTTOM BYPASS SYSTEM
Bottom bypass system is introduced in 03-M Series
for improving the cooling performance of the radiator.
While the temperature of coolant in the engine is low,
the thermostat is held closed and the coolant is allowed
to flow through the bypass pipe and to circulate in the
engine.
When the temperature exceeds the thermostat valve
opening level, the thermostat fully opens itself to prevent
the hot coolant from flowing through the bypass into the
engine.
In this way, the radiator can increase its cooling
performance.

3. FUEL SYSTEM
[1] GOVERNOR
The governor serves to keep engine speed constant
by automatically adjusting the amount of fuel supplied to
the engine according to changes in the load. This engine
employs an all-speed governor which controls the
centrifugal force of the steel ball (1) weight, produced by
rotation of the fuel camshaft (5), and the tension of the
governor spring 1 (7) and 2 (8) are balanced.
W1017186
QAt Start
Flowing of the battery current into the engine stop
solenoid (16), the plunger (17) is actuated to arrow
direction.
Since the steel ball (1) have no centrifugal force, the
control rack (14) is pushed to the right by the start spring
(13). Accordingly, the control rack (14) moves to the
maximum injection position to assure easy starting.

DIESEL ENGINE
03-M Series, WSM
QAt Idling
When the speed control lever is set at the idling
position after the engine starts, the governor spring 1 (7)
does not work at all and the governor spring 2 (8) does
only act slightly. The governor sleeve (2) is pushed
leftward by a centrifugal force of steel ball (1).
Therefore, the fork lever 1 (10) and control rack (14)
are moved to the left by the governor sleeve (2) and then
the start spring (13) is compressed by the control rack
(14). As a result, the control rack (14) is kept at a position
where a centrifugal force of steel ball (1) and forces of
start spring (13), governor spring 2 (8) are balanced,
providing stable idling.
W1017317
QAt High Speed Running with Overload
When an overload is applied to the engine running at
a high speed, the centrifugal force of steel ball (1)
becomes small as the engine speed is dropped, and fork
lever 2 (9) is pulled to the right by the governor springs 1
(7) and 2 (8), increasing fuel injection. Though, fork lever
2 (9) becomes ineffective in increasing fuel injection
when it is stopped by the adjusting screw (21).
After that, when the force of torque spring (20)
becomes greater than the centrifugal force of the steel
ball (1), fork lever 1 (10) moves rightward to increase fuel
injection, causing the engine to run continuously at a high
torque.
W1017384
QTo Stop Engine
When the battery current stops, the plunger (17) of
engine stop solenoid (16) is returned to the original
position, the spring (22) to keep the control rack (14) in
“No fuel injection” position.

[2] GENERAL PRECAUTION
• During disassembly, carefully arrange removed parts in a clean
area to prevent confusion later. Screws, bolts and nuts should be
replaced in their original position to prevent reassembly errors.
• When special tools are required, use KUBOTA genuine special
tools. Special tools which are not frequently used should be
made according to the drawings provided.
• Before disassembling or servicing live wires, make sure to
always disconnect the grounding cable from the battery first.
• Remove oil and dirt from parts before measuring.
• Use only KUBOTA genuine parts for parts replacement to
maintain engine performance and to ensure safety.
• Gaskets and O-rings must be replaced during reassembly.
Apply grease to new O-rings or oil seals before assembling.
• When reassembling external or internal snap rings, position them
so that the sharp edge faces against the direction from which
force is applied.
• Be sure to perform run-in the serviced or reassembled engine.
Do not attempt to give heavy load at once, or serious damage
may result to the engine.
