05-E2B, 05-E2BG, 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 whilefatigued.

• Wear close fitting clothing and safety equipmentappropriate 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 morepersons, take care to perform all work safely.

• Do not touch the rotating or hot parts while the engineis running.

• Never remove the radiator cap while the engine isrunning, or immediately after stopping. Otherwise, hotwater will spout out from radiator. Only removeradiator cap when cool enough to touch with barehands. Slowly loosen the cap to first stop to relievepressure before removing completely.

• Escaping fluid (fuel or hydraulic oil) under pressurecan penetrate the skin causing serious injury. Relievepressure before disconnecting hydraulic or fuel lines.Tighten all connections before applying pressure.

• Wear a suitable hearing protective device such asearmuffs or earplugs to protect against objectionableor uncomfortable loud noises.

AVOID FIRES• Fuel is extremely flammable and explosive under

certain conditions. Do not smoke or allow flames orsparks in your working area.

• To avoid sparks from an accidental short circuit,always disconnect the battery negative cable first andconnect it last.

• Battery gas can explode. Keep sparks and openflame away from the top of battery, especially whencharging the battery.

• Make sure that no fuel has been spilled on the engine.

05-E2B, 05-E2BG, WSM SAFETY INSTRUCTIONS

VENTILATE WORK AREA• If the engine must be running to do some work, make

sure the area is well ventilated. Never run the enginein a closed area. The exhaust gas contains poisonouscarbon monoxide.

DISPOSE OF FLUIDS PROPERLY• Do not pour fluids into the ground, down a drain, or

into a stream, pond, or lake. Observe relevantenvironmental protection regulations when disposingof oil, fuel, coolant, electrolyte and other harmfulwaste.

PREVENT ACID BURNS• Sulfuric acid in battery electrolyte is poisonous. It is

strong enough to burn skin, clothing and causeblindness if splashed into eyes. Keep electrolyteaway from eyes, hands and clothing. If you spillelectrolyte on yourself, flush with water, and getmedical 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 yourtelephone.

[2] E2B ENGINE[ex. Model Name D1105-E2B]The emission controls that have been put into effect in various countries to prevent air pollution will be stepped up.

The time to enforce the regulations differs depending on the engine output classifications.Kubota has been supplying the diesel engines conforming to the emission regulations in respective countries.

Exhaust emissions regulations shift to the second stage. Kubota executed the improvement of the engine accordingto this regulation.

In order to discriminate the engines conforming to Tier 1 / Phase 1 requirements and those conforming to Tier 2 /Phase 2 requirements, we have adopted E2B as a new model name for the engines conforming Tier 2 / Phase 2regulations.

In the after-sale services for 05-E2B and 05-E2BG series engines, only use the dedicated parts for E2B modelsand carry out the maintenance services accordingly.

2. GENERAL PRECAUTIONS• During disassembly, carefully arrange removed parts in a clean

area to prevent confusion later. Screws, bolts and nuts should bereplaced in their original position to prevent reassembly errors.

• When special tools are required, use KUBOTA genuine specialtools. Special tools which are not frequently used should bemade according to the drawings provided.

• Before disassembling or servicing live wires, make sure toalways 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 whichforce is applied.

• Be sure to perform run-in the serviced or reassembled engine.Do not attempt to give heavy load at once, or serious damagemay result to the engine.

CAUTION• When changing or inspecting, be sure to level and stop the engine. NOTE

Lubricating OilWith the emission control now in effect, the CF-4 and CG-4 lubricating oils have been developed for use of a low-

sulfur fuel on-road vehicle engines. When an off-road vehicle engine runs on a high-sulfur fuel, it is advisable toemploy the CF, CD or CE lubricating oil with a high total base number. If the CF-4 or CG-4 lubricating oil is used witha high-sulfur fuel, change the lubricating oil at shorter intervals.• Lubricating oil recommended when a low-sulfur or high-sulfur fuel is employed.

Checking Engine Oil Level1. Level the engine.2. To check the oil level, draw out the dipstick (1), wipe it clean,

reinsert it, and draw it out again.Check to see that the oil level lies (A) between the two notches.

3. If the level is too low, add new oil to the specified level.IMPORTANT

• When using an oil of different maker or viscosity from theprevious, drain old oil. Never mix two different types of oil.NOTE

• Be sure to inspect the engine, locating it on a horizontalplace. If placed on gradients, accurately, oil quantity maynot be measured.

• Be sure to keep the oil level between upper and lower limitsof the dipstick. Too much oil may cause a drop in output orexcessive blow-by gas. On the closed breather type enginein which mist is sucked through port, too much oil maycaused oil hammer. While too little oil, may seize theengine’s rotating and sliding parts.

Anti-Freeze• There are two types of anti-freeze available: use the permanent

type (PT) for this engine.• Before adding anti-freeze for the first time, clean the radiator

interior by pouring fresh, soft water and draining it a few times.• The procedure for mixing water and anti-freeze differs according

to the make of the anti-freeze and the ambient temperature.Basically, it should be referred to SAE J1034 standard, morespecifically also to SAE J814c.

• Mix the anti-freeze with fresh, soft water, and then fill into theradiator.IMPORTANT

• When the anti-freeze is mixed with fresh, soft water, the anti-freeze mixing ratio must be less than 50 %.

* At 1.013 × 100000 Pa (760 mmHg) pressure (atmospheric). Ahigher boiling point is obtained by using a radiator pressure capwhich permits the development of pressure within the coolingsystem.

NOTE• The above data represents industrial standards that

necessitate a minimum glycol content in the concentratedanti-freeze.

• When the coolant level drops due to evaporation, add fresh,soft water only to keep the anti-freeze mixing ratio less than50 %. In case of leakage, add anti-freeze and fresh, softwater in the specified mixing ratio.

• Anti-freeze absorbs moisture. Keep unused anti-freeze in atightly sealed container.

• Do not use radiator cleaning agents when anti-freeze hasbeen added to the coolant.(Anti-freeze contains an anti-corrosive agent, which willreact with the radiator cleaning agent forming sludge whichwill affect the engine parts.)

electrolyte level.(Reference)• Specific gravity slightly varies with temperature. To be exact, the

specific gravity decreases by 0.0007 with an increase of 1 °C(0.0004 with an increase of 1 °F) in temperature, and increasesby 0.0007 with a decreases of 1 °C (0.0004 with a decrease of 1°F).Therefore, using 20 °C (68 °F) as a reference, the specific gravityreading must be corrected by the following formula :- Specific gravity at 20 °C = Measured value + 0.0007 ×

Changing Radiator Coolant (L.L.C.) (Continued)(Anti-freeze)• There are two types of anti-freeze available: use the permanent

type (PT) for this engine.• Before adding anti-freeze for the first time, clean the radiator

interior by pouring fresh, soft water and draining it a few times.• The procedure for mixing water and anti-freeze differs according

to the make of the anti-freeze and the ambient temperature.Basically, it should be referred to SAE J1034 standard, morespecifically also to SAE J814c.

• Mix the anti-freeze with fresh, soft water, and then fill into theradiator.IMPORTANT

• When the anti-freeze is mixed with fresh, soft water, the anti-freeze mixing ratio must be less than 50 %.

* At 1.013 × 100000 Pa (760 mmHg) pressure (atmospheric). Ahigher boiling point is obtained by using a radiator pressure capwhich permits the development of pressure within the coolingsystem.

NOTE• The above data represents industrial standards that

necessitate a minimum glycol content in the concentratedanti-freeze.

• When the coolant level drops due to evaporation, add fresh,soft water only to keep the anti-freeze mixing ratio less than50 %. In case of leakage, add anti-freeze and fresh, softwater in the specified mixing ratio.

• Anti-freeze absorbs moisture. Keep unused anti-freeze in atightly sealed container.

• Do not use radiator cleaning agents when anti-freeze hasbeen added to the coolant.(Anti-freeze contains an anti-corrosive agent, which willreact with the radiator cleaning agent forming sludge whichwill affect the engine parts.)

[2] GOVERNORThree Lever Type Fork Lever (for General)The governor system is a mechanical governor that

used the flyweight (5).The flyweight (5) is mounted on the governor shaft

that rotates at the same speed as the crankshaft.Because the feature of this mechanism takes out the

engine speed directly as a centrifugal force of weight, thespeed control that the change in the engine rotationalspeed is sensitively transmitted to fork lever assembly(A) and accuracy is high is enabled.

The fork lever assembly of this engine is composed offork lever 1 (6), for lever 2 (9), and the floating lever (7).A slide plate is installed in fork lever 1. The governorspring (3) is hooked to fork lever 2 (9).

The floating lever (7) installs the torque pin (8) of theoutput drop prevention at the overload. The start spring(2) is hooked to a slide plate, and holds the control rackin the direction of the full fuel position.

Fork lever 2 (9) and the floating lever are installed infork lever 1 (6) with the fork lever shaft (4). The maxtorque limitation (1) device limits the amount of the fuelexhalation at the overload with the torque pin.

W1012753

(At Rated Operation)When the engine is running, the fork lever 2 (9) and

the floating lever (7) are moving with the fork lever 1 (6)due to the tension of the governor spring (3).

During the time, the torque pin (8) is pressed into thefloating lever by centrifugal force of the governor weight(5).

The fork lever 2 (9) comes in contact with the fuellimitation bolt (10), and the fuel injection pump supplies afuel necessary for rated operation.

(Overloaded Operation)The amount of the movement of the fork lever

assembly is limited with the fuel limitation bolt (10) andcan not be moved in the direction of the fuel increase.

As overload reduces the centrifugal force of thegovernor weight, which is pressing the torque pin (8) intothe floating lever (7), the floating lever pushes the forklever 1 (6) in the way to increase the fuel supply with thehelp of the torque spring tension.

The fuel supply increases (b) in relation to the degreeof the torque pin motion, thus preventing the enginespeed from dropping.

At the time, the maximum torque limiter (1) preventssuperfluous fuel supply and suppresses the generationof black smoke.

Two Lever Type Fork Lever (for BG Series)The engine speeds of BG engine are 1500 min-1

(rpm) and 1800 min-1 (rpm) specifications.The fork lever assembly of BG series is composed of

fork lever 1 (3), fork lever 2 (4).A slide plate is installed in fork lever 1. The governor

spring (5) is hooked to fork lever 2 (4).The start spring is hooked to a slide plate, and holds

the control rack in the direction of full fuel position.Fork lever 2 (4) and fork lever 1 (3) are installed with

Battery Specific Gravity1. Check the specific gravity of the electrolyte in each cell with a

hydrometer.2. When the electrolyte temperature differs from that at which the

hydrometer was calibrated, correct the specific gravity readingfollowing the formula mentioned in (Reference).

3. If the specific gravity is less than 1.215 (after it is corrected fortemperature), charge or replace the battery.

4. If the specific gravity differs between any two cells by more than0.05, replace the battery.NOTE

• Hold the hydrometer tube vertical without removing it fromthe electrolyte.

• Do not suck too much electrolyte into the tube.• Allow the float to move freely and hold the hydrometer at eye

level.• The hydrometer reading must be taken at the highest

electrolyte level.(Reference)• Specific gravity slightly varies with temperature. To be exact, the

specific gravity decreases by 0.0007 with an increase of 1 °C(0.0004 with an increase of 1 °F) in temperature, and increasesby 0.0007 with a decreases of 1 °C (0.0004 with a decrease of 1°F).Therefore, using 20 °C (68 °F) as a reference, the specific gravityreading must be corrected by the following formula :- Specific gravity at 20 °C = Measured value + 0.0007 ×

(electrolyte temperature : 20 °C)- Specific gravity at 68 °F = Measured value + 0.0004 ×

(electrolyte temperature : 68 °F)
