SAFETY NOTICE
IMPORTANT SAFETY NOTICE
Proper service and repair is extremely important for safe machine operation. The service and
repair techniques recommended by Komatsu and described in this manual are both effective
and safe. Some of these techniques require the use of tools specially designed by Komatsu for
the specific purpose.
To prevent injury to workers, the symbol k is used to mark safety precautions in this manual.
The cautions accompanying these symbols should always be followed carefully. If any danger-
ous situation arises or may possibly arise, first consider safety, and take the necessary actions
to deal with the situation.
GENERAL PRECAUTIONS
Mistakes in operation are extremely dangerous.
Read the Operation and Maintenance Manual care-
fully BEFORE operating the machine.
1. Before carrying out any greasing or repairs, read
all the precautions given on the decals which are
fixed to the machine.
2. When carrying out any operation, always
wear safety shoes and helmet. Do not wear
loose work clothes, or clothes with buttons
missing.
• Always wear safety glasses when hitting
parts with a hammer.
• Always wear safety glasses when grinding
parts with a grinder, etc.
3. If welding repairs are needed, always have a
trained, experienced welder carry out the work.
When carrying out welding work, always wear
welding gloves, apron, hand shield, cap and
other clothes suited for welding work.
4. When carrying out any operation with two or
more workers, always agree on the operating
procedure before starting. Always inform your
fellow workers before starting any step of the
operation. Before starting work, hang UNDER
REPAIR signs on the controls in the operator's
compartment.
5. Keep all tools in good condition and learn the
correct way to use them.
6. Decide a place in the repair workshop to keep
tools and removed parts. Always keep the tools
and parts in their correct places. Always keep
the work area clean and make sure that there is
no dirt or oil on the floor. Smoke only in the areas
provided for smoking. Never smoke while work-
ing.
PREPARATIONS FOR WORK
7. Before adding oil or making any repairs, park the
machine on hard, level ground, and block the
wheels or tracks to prevent the machine from
moving.
8. Before starting work, lower blade, ripper, bucket
or any other work equipment to the ground. If
this is not possible, insert the safety pin or use
blocks to prevent the work equipment from fall-
ing. In addition, be sure to lock all the control
levers and hang warning signs on them.
9. When disassembling or assembling, support the
machine with blocks, jacks or stands before
starting work.
10.Remove all mud and oil from the steps or other
places used to get on and off the machine.
Always use the handrails, ladders or steps when
getting on or off the machine. Never jump on or
off the machine. If it is impossible to use the
handrails, ladders or steps, use a stand to pro-
vide safe footing.
10. SAFETY SAFETY NOTICE
00-4
PRECAUTIONS DURING WORK
11.When removing the oil filler cap, drain plug or
hydraulic pressure measuring plugs, loosen
them slowly to prevent the oil from spurting out.
Before disconnecting or removing components
of the oil, water or air circuits, first remove the
pressure completely from the circuit.
12.The water and oil in the circuits are hot when the
engine is stopped, so be careful not to get
burned.
Wait for the oil and water to cool before carry-
ing out any work on the oil or water circuits.
13.Before starting work, remove the leads from the
battery. Always remove the lead from the nega-
tive (–) terminal first.
14.When raising heavy components, use a hoist or
crane.
Check that the wire rope, chains and hooks are
free from damage.
Always use lifting equipment which has ample
capacity.
Install the lifting equipment at the correct places.
Use a hoist or crane and operate slowly to pre-
vent the component from hitting any other part.
Do not work with any part still raised by the hoist
or crane.
15.When removing covers which are under internal
pressure or under pressure from a spring,
always leave two bolts in position on opposite
sides. Slowly release the pressure, then slowly
loosen the bolts to remove.
16.When removing components, be careful not to
break or damage the wiring. Damaged wiring
may cause electrical fires.
17.When removing piping, stop the fuel or oil from
spilling out. If any fuel or oil drips onto the floor,
wipe it up immediately. Fuel or oil on the floor
can cause you to slip, or can even start fires.
18.As a general rule, do not use gasoline to wash
parts. In particular, use only the minimum of
gasoline when washing electrical parts.
19.Be sure to assemble all parts again in their origi-
nal places.
Replace any damaged parts with new parts.
• When installing hoses and wires, be sure
that they will not be damaged by contact
with other parts when the machine is being
operated.
20.When installing high pressure hoses, make sure
that they are not twisted. Damaged tubes are
dangerous, so be extremely careful when install-
ing tubes for high pressure circuits. Also, check
that connecting parts are correctly installed.
21.When assembling or installing parts, always use
the specified tightening torques. When installing
protective parts such as guards, or parts which
vibrate violently or rotate at high speed, be par-
ticularly careful to check that they are installed
correctly.
22.When aligning two holes, never insert your fin-
gers or hand. Be careful not to get your fingers
caught in a hole.
23.When measuring hydraulic pressure, check that
the measuring tool is correctly assembled before
taking any measurements.
24.Take care when removing or installing the tracks
of track-type machines.
When removing the track, the track separates
suddenly, so never let anyone stand at either
end of the track.

00-7
HOISTING INSTRUCTIONS
HOISTING
k Heavy parts (25 kg or more) must be lifted
with a hoist, etc. In the DISASSEMBLY
AND ASSEMBLY section, every part
weighing 25 kg or more is indicated clearly
with the symbol
• If a part cannot be smoothly removed from the
machine by hoisting, the following checks
should be made:
1) Check for removal of all bolts fastening the
part to the relative parts.
2) Check for existence of another part causing
interference with the part to be removed.
WIRE ROPES
1) Use adequate ropes depending on the
weight of parts to be hoisted, referring to
the table below:
Wire ropes
(Standard "Z" or "S" twist ropes
without galvanizing)
★ The allowable load value is estimated to be one-
sixth or one-seventh of the breaking strength of
the rope used.
2) Sling wire ropes from the middle portion of the
hook.
Slinging near the edge of the hook may cause
the rope to slip off the hook during hoisting, and
a serious accident can result. Hooks have max-
imum strength at the middle portion.
3) Do not sling a heavy load with one rope alone,
but sling with two or more ropes symmetrically
wound onto the load.
k Slinging with one rope may cause turning
of the load during hoisting, untwisting of
the rope, or slipping of the rope from its
original winding position on the load, which
can result in a dangerous accident.
4) Do not sling a heavy load with ropes forming a
wide hanging angle from the hook.
When hoisting a load with two or more ropes,
the force subjected to each rope will increase
with the hanging angles. The table below
shows the variation of allowable load kN {kg}
when hoisting is made with two ropes, each of
which is allowed to sling up to 9.8 kN {1000 kg}
vertically, at various hanging angles.
When two ropes sling a load vertically, up to
19.6 kN {2000 kg} of total weight can be sus-
pended. This weight becomes 9.8 kN {1000 kg}
when two ropes make a 120° hanging angle.
On the other hand, two ropes are subjected to
an excessive force as large as 39.2 kN {4000
kg} if they sling a 19.6 kN {2000 kg} load at a
lifting angle of 150°.

METHOD OF DISASSEMBLING, CONNECTING PUSH-PULL TYPE COUPLER
k Before carrying out the following work, release
the residual pressure from the hydraulic tank.
For details, see TESTING AND ADJUSTING,
Releasing residual pressure from hydraulic
tank.
k Even if the residual pressure is released from
the hydraulic tank, some hydraulic oil flows out
when the hose is disconnected. Accordingly,
prepare an oil receiving container.
Disconnection
1) Release the residual pressure from the hydrau-
lic tank. For details, see TESTING AND
ADJUSTING, Releasing residual pressure from
hydraulic tank.
2) Hold adapter (1) and push hose joint (2) into
mating adapter (3). (See Fig. 1)
★ The adapter can be pushed in about 3.5
mm.
★ Do not hold rubber cap portion (4).
3) After hose joint (2) is pushed into adapter (3),
press rubber cap portion (4) against (3) until it
clicks. (See Fig. 2)
4) Hold hose adapter (1) or hose (5) and pull it out.
(See Fig. 3)
★ Since some hydraulic oil flows out, prepare
an oil receiving container.
Connection
1) Hold hose adapter (1) or hose (5) and insert it in
mating adapter (3), aligning them with each
other. (See Fig. 4)
★ Do not hold rubber cap portion (4).
2) After inserting the hose in the mating adapter
perfectly, pull it back to check its connecting
condition. (See Fig. 5)
★ When the hose is pulled back, the rubber
cap portion moves toward the hose about
3.5 mm. This does not indicate abnormality,
however.

CONVERSION TABLE
METHOD OF USING THE CONVERSION TABLE
The Conversion Table in this section is provided to enable simple conversion of figures. For details of the
method of using the Conversion Table, see the example given below.
EXAMPLE
• Method of using the Conversion Table to convert from millimeters to inches
1. Convert 55 mm into inches.
(1) Locate the number 50 in the vertical column at the left side, take this as (A), then draw a horizontal line
from (A).
(2) Locate the number 5 in the row across the top, take this as (B), then draw a perpendicular line down
from (B).
(3) Take the point where the two lines cross as (C). This point (C) gives the value when converting from
millimeters to inches. Therefore, 55 mm = 2.165 inches.
2. Convert 550 mm into inches.
(1) The number 550 does not appear in the table, so divide by 10 (move the decimal point one place to the
left) to convert it to 55 mm.
(2) Carry out the same procedure as above to convert 55 mm to 2.165 inches.
(3) The original value (550 mm) was divided by 10, so multiply 2.165 inches by 10 (move the decimal point
one place to the right) to return to the original value. This gives 550 mm = 21.65 inches.

Temperature
Fahrenheit-Centigrade Conversion ; a simple way to convert a Fahrenheit temperature reading into a Cen-
tigrade temperature reading or vice versa is to enter the accompanying table in the center or boldface col-
umn of figures.
These figures refer to the temperature in either Fahrenheit or Centigrade degrees.
If it is desired to convert from Fahrenheit to Centigrade degrees, consider the center column as a table of
Fahrenheit temperatures and read the corresponding Centigrade temperature in the column at the left.
If it is desired to convert from Centigrade to Fahrenheit degrees, consider the center column as a table of
Centigrade values, and read the corresponding Fahrenheit temperature on the right.

Outline
• The power from engine (15) is transmitted
through the flywheel to torque converter (16).
The torque converter uses oil as a medium to
vary the transmission torque according to the
change in the load. It transmits the power to
the transmission input shaft.
The power from the engine passes through
the torque converter pump drive gear and is
transmitted to steering pump (20), switch pump
(21), cooling fan drive pump (22), transmission
and torque converter charging pump (17), work
equipment hydraulic pump (18), and PPC
pump (19) to drive these pumps.
• Transmission (8) operates the directional valves
and speed valves in the transmission to actuate
the 6 hydraulically operated clutches and select
one of the 4 FORWARD or REVERSE speeds.
• Parking brake (7) is applied by an electromag-
netic valve that is actuated when the parking
brake switch is operated. It is a wet-type multi-
ple-disc brake installed to the front of the out-
put shaft to stop the machine.
• The power from the output shaft of transmis-
sion (8) is transmitted to the front and rear
axles. At the front, the power is transmitted to
front axle (1) through center drive shaft (6),
flange bearing (23), and front drive shaft (5).
At the rear, it is transmitted to rear axle (14)
through rear drive shaft (9).
• The power transmitted to front axle (1) and rear
axle (14) is reduced by the pinion gear in differ-
entials (2) and (13), and is transmitted through
the differential mechanism to the sun gear
shaft.
• The power from the sun gear is further reduced
by planetary-type final drive (11) and is trans-
mitted to the wheels through the axle shaft.

• The power from the transmission output shaft
passes through center drive shaft (3), front
drive shaft (1), and rear drive shaft (4), and is
transmitted to the front axle and rear axle.
• When the body is articulated, or when the
machine is traveling and there is shock from
the ground surface, or when there is shock dur-
ing operations, the position of the transmis-
sion and the front and rear axles changes. The
transmission is designed so that even if the
position of the components changes as a
result of such shock, power can be transmitted
without damage to any parts. With this
design, the drive shafts have universal joints
and flange bearings that enable them to han-
dle any changes in the angle and length.

Path of power transmission
Flow of power
• The torque converter is installed between the
engine and transmission.
The power from the engine goes from flywheel
(1) and enters drive case (2).
Drive case (2), pump (3), and PTO gear (4) are
each fixed by bolts and are rotated directly by
the rotation of the engine.
• The power from pump (3) uses oil as a medium
to rotate turbine (5) and transmit the power to
transmission input shaft (6).
The power from drive case (2) passes through
PTO gear (4) and is used as the power to drive
the gear pump.
Flow of oil
• The oil passes through the main relief valve and
its pressure is adjusted by the torque con-
verter relief valve so that it is less than the set
pressure. It then enters inlet port A, passes
through the passage in stator shaft (7), and
flows to pump (3).
The oil is given centrifugal force by pump (3).
It then enters turbine (5) and transmits the
energy of the oil to the turbine.
• Turbine (5) is fixed to transmission input shaft
(6), so the power is transmitted to the trans-
mission input shaft. The oil from turbine (5) is
sent to stator (8), and enters the pump again.
However, part of the oil is sent from stator (8)
through outlet port B to the cooler.

Flow of power
Lock-up clutch disengaged
• When the lock-up clutch is disengaged, the con-
nection of drive case (3) and turbine (4) is dis-
connected, and the torque converter functions
as normal.
The power generated by the engine is transmit-
ted from flywheel (1) to clutch housing (2), and
rotates drive case (3) and pump (6) as one unit.
The power from pump (6) uses oil as a medium
to rotate turbine (4) and transmits the power
from turbine (4) to transmission input shaft (14).
Lock-up clutch engaged
• When the lock-up clutch is engaged, drive case
(3) and turbine (4) are connected and form one
unit. Stator (11) is rotated by the rotation of
pump (6) and turbine (4).
The power generated by the engine is transmit-
ted from flywheel (1) to clutch housing (2), and
rotates drive case (3) and pump (6) as one
unit.In addition, drive case (3) and turbine (4)
are connected by the clutch, so the power is
transmitted directly from turbine (4) to trans-
mission input shaft (14) without using oil as a
medium.

Operation of clutch
Clutch engaged
• The oil sent from the transmission valve passes
through the passage inside shaft (1), goes to
the back face of piston (6), and actuates piston
(6).
• When piston (6) is actuated, separator plate (2)
and friction plate (3) are pressed together, so
shaft (1) and clutch gear (4) form one unit, and
transmit the power.
When this happens, the oil is drained from oil
drain hole (5), but the amount of oil drained is
less than the amount of oil supplied, so there is
no influence on the operation of the clutch.
Clutch disengaged
• The oil sent from the transmission valve is shut
off, so the pressure of the oil acting on the back
face of piston (6) drops.
• Piston (6) is returned to its original position by
wave spring (7), and shaft (1) and clutch gear (4)
are separated.
• When the clutch is disengaged, the oil at the
back face of the piston is drained through oil
drain hole (5) by centrifugal force to prevent the
clutch from remaining partially engaged.
★ Oil drain hole (5) is provided only in the 1st,
2nd, 3rd, and 4th clutches.

TRANSMISSION CONTROL VALVE
ECMV actuation table
Outline
• The oil from the pump passes through the flow
valve, is filtered by the oil filter, enters the
transmission control valve, and is separated
into the main relief circuit and clutch actuation
circuit.
• The oil pressure adjusted by the main relief
valve and flowing to the clutch actuation circuit
passes through the last-chance filter and actu-
ates the clutch and parking brake. The oil
relieved by the main relief valve is supplied to
the torque converter.
• When the transmission shifts gear, the ECMV
uses the command current from the transmis-
sion controller to raise the clutch oil pressure
smoothly in order to reduce the transmission
shock. In addition, it keeps the clutch pressure
constant when the machine is traveling.
• By switching the F, R, and 1st – 4th ECMVs, the
adjusted oil pressure is supplied to the selected
clutch to provide the necessary speed range.
