TO

THE

READER

This Workshop Manual has been prepared to provide servicing personnel with

information on the mechanism, service and maintenance of

KUBOTA

Diesel Engines

05

SERIES.

It

is divided into

two

parts, “Mechanism” and “Disassembling and Servicing” for

each section.

Mechanism

Information on the construction and function are included for each engine section. This

part should be understood before proceeding with troubleshooting, disassembling and

servicing.

H

Disassembling and Servicing

Under the heading ”General” section comes general precautions, troubleshooting, lists

of servicing specifications and periodic inspection items. For each engine section, there

are “Checking and Adjustment“, “Disassembling and Assembling”, and “Servicing” which

cover procedures, precautions, factory specification and allowable limits.

All

the engines that have been manufactures since January of

1994

are clean exhaust

The mark

[E]

in the WSM refers to the said clean engine.

SAFETY

STARTING

(1)

Do

not

start

the

engine by shorting across starter

terminals.

(2)

Unauthorized modifications

to

the engine may impair

the

function and /or safety and

affect

engine

life.

00000200031

SAFETY WORKING

(1)

Do

not work on

the

engine while under

the

influence

of

alcohol, medication, or other substances

or

while

fatigued.

(2)

Wear

close

fitting clothing and safety equipment

appropriate to

the

job.

(3)

Use

tools appropriate

to

the

work.

Makeshift

tools,

parts, and procedures

are

not recommended.

(4)

When servicing

is

performed together by<two or more

persons, take

care

to perform

all

work safely.

(5)

Do

not touch the rotating or hot parts while the engine

is

running.

(6)

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.

(7)

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.

(8)

Wear

a

suitable hearing protective device such

as

earmuffs

or

earplugs

to

protect against objectionable

or

uncomfortable loud noises.

AVOID

FIRES

(1)

Fuel

is

extremely flammable and explosive under

certain conditions.

Do

not smoke or allow flames or

sparks in your working

area.

(2)

To

avoid sparks from an accidental short circuit,

always disconnect the battery negative cable first

and connect

it

last.

(3)

Battery gas can explode. Keep sparks and open

flame

away from the top

of

battery, especially when

charging the battery.

(4)

Make

sure

that

no fuel has been spilled

on

the

engine.

VENTILATE

WORK

AREA

(1)

If the engine must be running to do same work, make

sure the area is well ventilated. Never run the engine

in a closed area. The exhaust gas contains

poisonous carbon monoxide.

00000200060

PREVENT ACID BURNS

(1)

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.

The

05

SERIES

ENGINE are vertical, water-cooled,

4

cycle diesel engines.

They are incorporated KUBOTA's foremost

technologies. With

KUBOTA's

E-TVCS (Three Vortex

Combustion System), well-known Bosch

MD

type

injection

pump

and the well-balanced designs, they give

greater power, low fuel consumption, little vibration and

quiet operation.

NOTE

0

Since January 1994, E-NCS has been used for

the combustion chamber

of

our products instead

of traditional N-NCS.

E-TVCS was developed with an eye toward clean

exhaust gas which

is

more environmentally

freindly.

The combustion chamber models mentioned

hereinafter refers to

E-TVCS.

The engine has a high durability tunnel-type cylinder

block in which the crank bearing component is a

constructed body.

Furthermore, liner less type, allow effective cooling,

less distortion, and greater wear-resistance.

The noise level is reduced to a minimum because

each cylinder has its own chamber.

11900M10020

The cross-flow type intake

/

exhaust ports in this

engine have their openings at both sides of the cylinder

head. Because overlaps

of

intake

/

exhaust ports are

smaller than in ports

of

other types which have openings

on one side, the suction air can be protected from being

heated and expanded by heated exhaust air. The cool,

high density suction air has high volume efficiency and

raises the power

of

the engine. Furthermore, distortion

of

the cylinder head by heated exhaust gas is reduced

because intake ports are arranged alternately.

The combustion chamber is

of

KUBOTA's exclusive

E-TVCS

combustion chamber type. Suction air

is

whirled to be mixed effectively with fuel, prompting

combustion and reducing fuel consumption.

In the combustion chamber are installed throttle type

injection nozzle and rapid heating sheathed type glow

plug. This glow plug assures easier than ever engine

starts even at

The crankshaft with the connecting rod converts the

reciprocating motion

of

the piston into the rotating

motion.

The crankshaft is made of tough special alloy steel,

and the journals, pins and oil seal sliding portions are

induction hardened to increase the hardness for higher

wear resistance.

The front journal is supported by

a

solid type bearing,

the intermediate journal by a split type, and the rear

journal by a split type with thrust bearings.

The crankshaft is provided with an oil gallery, through

which engine oil is fed to the crankpin portion, and

lubricates it.

The piston has a slightly oval shape when cold (in

consideration of thermal expansion) and a concave

head.

Three rings are installed in grooves

in

the piston.

The top ring

(1)

is a keystone type, which can stand

against heavy loads, and the barrel face on the ring fits

well to the cylinder wall.

The second ring

(2) is an undercut type, which

effectively prevents the oil from being carried up.

The oil ring

(3)

has chamfered contact faces and an

expander ring, which increase the pressure of the oil ring

against the cylinder wall.

Several grooves are cut

on

the top land to help heat

dissipate and to prevent scuffing.
