Proper service and repair is extremely important for the safe operation of your machine.
The service and repair techniques recommended by Komatsu and described in this
manual are both effective and safe methods of operation. Some of these operations re-
quire the use of tools specially designed by Komatsu for the purpose.
A
iY
To prevent injury to workers, the symbols and
*
are used to mark safety pre-
cautions in this manual. The cautions accompanying these symbols should always be
followed carefully. If any dangerous situation arises or may possibly arise, first consider
safety, and take the necessary actions to deal with the situation.
A SAFETY
GENERAL PRECAUTIONS
Mistakes in operation are extremely dangerous.
Read the Operation and Maintenance Manual
carefully 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.
l 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, glasses,
cap and other clothes suited for welding
work.
4.When carrying out any operation with two
or more workers, always agree on the op-
erating 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 working.
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 falling. In addition, be sure
to lock all the control levers and hang
warning signs on them.
9. When disassembling or assembling, sup-
port 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 provide safe
footing.
00-3
10. PRECAUTIONS DURING WORK
1 1. 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 compo-
nents 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 car-
rying 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 negative (-1 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 prevent the component from hit-
ting any other part. Do not work with any
part still raised by the hoist or crane.
15 When removing covers which are under in-
ternal 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 on to
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 mini-
mum of gasoline when washing electrical
parts.
19 Be sure to assemble all parts again in their
original 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 ma-
chine is being operated.
20 ‘. When installing high pressure hoses, make
sure that they are not twisted. Damaged
tubes are dangerous, so be extremely care-
ful when installing 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 particularly careful to check
that they are installed correctly.
22. When aligning two holes, never insert your
fingers 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 assem-
bled before taking any measurements.
24. Take care when removing or installing the
tracks of track-type machines.
When removing the track, the track sepa-
rates suddenly, so never let anyone stand at
either end of the track.

13. HOISTING INSTRUCTIONS
HOISTING INSTRUCTIONS
A Heavy parts (25 kg or more) must be
lifted with a hoist etc. In the Disassembly
and Assembly section, every part weigh-
ing 25 kg or more is indicated clearly with
the symbol &
1. If a part cannot be smoothly removed from
the machine by hoisting, the following
checks should be made:
. Check for removal of all bolts fastening
the part to the relative parts.
. Check for existence of another part
causing interference with the part to be
removed.
2. 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)
Rope diameter (mm) Allowable load (tons)
10 1.o
11.2 1.4
12.5 1.6

20 4.4
22.4 5.6
30 10.0
40 18.0
50 28.0
60 40.0
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 maximum strength at the
middle portion.
100% as% 79% 71% 41%
FSO064
3) Do not sling a heavy load with one rope
alone, but sling with two or more ropes
symmetrically wound on to the load.
A 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 (kg) when hoisting is made
with two ropes, each of which is allowed
to sling up to 1000 kg vertically, at various
hanging angles.
When two ropes sling a load vertically, up
to 2000 kg of total weight can be
suspended. This weight becomes 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
4000 kg if they sling a 2000 kg load at a
lifting angle of 150”.

can be installed in their original condition at the
time of reassembly.
10. LINK RODS
1) If it is necessary to change the length of the
link rod in order to remove it, first record the
original length so that the rod can be easily
reassembled in its original condition.
2) Remove the link rod at the pins.

11 .SHIMS AND WASHERS
1) Shims are used to center the engine and
adjust the action of the bevel gears. Handle
very carefully as they get deformed easily.
2) Record the numbers and positions to speed
adjustment after reinstallation.
3) Do not reuse any shims or washers that are
deteriorated, damaged, bent or deformed.
4) Insert thin shims between thicker ones.
12. CENTERING
Centering is very important for interfaces in the
power train - for example, between the engine
and the transmission and between the
bevel gear shaft and the final drives. Incorrect
centering only increases the stresses acting on
the turning parts, so always make sure that the
deviation is within the specified limits.

21. MEASURING INSTRUCTIONS
MEASURING INSTRUCTIONS
PREPARATIONS BEFORE CHECKING BLOCK GAUGES
1. Cleaning of parts
Wash parts to be checked. Special care should be
paid to thoroughly remove dust and dirt from the
surfaces on which measurements are to be made
so that possible errors can be eliminated.
2. Minor repair of part surfaces
Remove scratches, dents and rust from parts to
be checked. If the surface are rough, the measure-
ments will be inaccurate. When smoothing any
surface, be careful not to use an oilstone or sand
paper coarser than the finished surface.
3. Preparation of measuring tools
Clean the tools and thoroughly remove dust and
dirt from the surfaces which contact parts. Check
the tools for proper function and zero-point
adjustment. Remedy any abnormality.
4. Maintenance of measuring tools
Handle all tools with sufficient care and do not
subject them to unreasonable force or shocks
which can affect their delicate construction. Peri-
odically check the tools for accuracy and, if
necessary, calibrate them. Put the tools back into
their cases and return them to their fixed storage
locations whenever not in use. It is recommended
to assign a person to be responsible for the proper
storage of measuring tools.
MEASURING TOOLS
Repeat each measurement two or three times to
eliminate possible errors. Further repetition will be
necessary, if there is a large variation in the
readings.
When measuring the inside or outside diameter of
a cylindrical object, take two readings with the
measuring device put in two directions at right
angles to each other. Repeat this at several points
along the overall length of the object.
Along eye-measurement below the unit of a scale
may be used for making a comparison between
two approximately equal measurements, the accu-
racy of such eye-measurements should not be
considered as reliable.
At the start of each measurement, select a
measuring device having an accuracy appropriate
for judging whether the measurement reaches its
allowable limit.
To bring two blocks into contact, wash each block
with benzene to remove rust-preventing oil and
wipe with a clean cotton cloth. Put one block on
the other, causing a sliding or twisting movement
between the two.
If the contact between two blocks feels rough,
apply a fine-grade oilstone to’ the blocks along
their edges. (Do not try to rub thecontact surface
of the blocks.)
Do not leave the blocks in contact for a long time.
Long-time contact will make the blocks difficult to
separate or cause black rust to appear on the con-
tact surfaces.
When separating two blocks, slide or twist them.
Do not try to pull them apart, by force or strike
them with a mallet.
When storing a block gauge, wipe off moisture,
dirt and fingerprints, coat with a rust-preventing
lubricant such as Vaseline, and put the gauge back
in its case.
VERNIER CALIPERS
At the start of measurement, close the jaws and
check that there is no clearance (due to wear) be-
tween the jaws and that the “zero” point of the
graduation is in exact alignment with the “zero”
point of the vernier scale.

against shock.
Set the zero-point of the gauge with care to keep
the movement of the contact-point within its
stroke during measurement.
Careless setting of the zero-point may cause the
spindle to retract or extend to its limit, thus
making measurement impossible.
The measurements ‘of the dial gauge are
accompanied by relatively large errors because
minute variations of the contact-point (and
accompanying errors) are indicated by the dial
pointer through an expanding mechanism using
gears. The reliability of eye measurements can not
be assured below the minimum unit on the scale.

1) Fully mesh one of two gears and place the dial
gauge contact-point on a tooth of the other
gear. Swing the free gear within the limits of its
play in the rotational directions, and read the

2) Use of the lever and fulcrum type dial gauge is
recommended for this purpose as the contact-
point placed on the gear is moved tangentially
to the gear pitch circle.
3) The lever and fulcrum type dial gauge is suitable
for use in a narrow space or for a special
measurement which requires placing the
contact-point on an object at an angle to the
spindle of the gauge.
Since the contact-point of this type of gauge
has a very narrow measuring range (usually 3
mm or less), the contact-point should be care-
fully checked for contact with the object during
measurement.
CYLINDER GAUGES
l Install a contact-point having a length approxi-
mately equal to the cylinder bore to the measured

test indicator to the bore diameter of the standard
cylinder measured with a reference ring gauge or
a micrometer.

the detachable rod used as the fulcrum.
l When the minimum reading is obtained on the
right side of the zero point of the test indicator,
and the reading to the standard value to which the
zero point is set.
When the minimum reading is obtained on the left
side of the zero point, subtract the reading from
the standard value.
PARTS CHECKING INSTRUCTIONS
l Check disassembled parts to see if they are reusa-
ble or need repair. If the part failed due to an exter-
nal source, determine the cause and correct
before assembly.
1. GENERAL PRECAUTIONS
l Visually inspect parts for cracks, pitting, cor-
rosion, scoring, ridging etc. To ensure proper
inspection, every part should be clean before
inspection.
l If the cause of the defect can be found, it will be a
great help to analyze the part condition; whether
the defect will progress or not, and the possibility
of future trouble.
Knowing the cause of the defect, the service man
can give good advice to the customer to prevent
him from having the same trouble again.
l Visual inspection can not find minute or hidden
damage. Other methods of inspection are as
follows;
a) Water-pressure or air-pressure test
b) Color check or magnetic damage test
2. CRACKS
3. PITTING
1) Pitting by cavitation
In most cases, cavitation is accompanied by
chemical corrosion. After removing rust or
scale, carefully inspect the depth of pitting.
l When the pitting can not be repaired within the
allowable limit, replace the part.
l If pitting is not deep, resurface the part after
removing the rust and scale.
2) Pitting due to removal of surface
l If ball bearing is pitted, replace it.
l If more than l/3 of the contact face is pitted,
the part should be replaced.
l If pitting is not serious, resurface the part.
l If the part is found to be cracked by visual
inspection, it should be replaced or repaired.
l If the length or depth of crack exceeds 113 of the
thickness of the part, it should be replaced instead
of repaired.
l A part having an internal crack should be replaced.

2. Inspection prior to installation
1) Keep the oil seals free from dust, rust and
scratches.
Take special care to prevent rust or scratches
on the lips.
2) To check the oil seal lip for smoothness, gently
slide a wire across its surface. If the wire
catches, replace the oil seal with a new one.
+ Make sure that the wire used for this test
does not scratch the lip surface.
3) Do not use the oil seal on a shaft where it
would come into contact with rust or scratches
on the shaft surface.
4) When removing the oil seal, take care not to
damage the housing or shaft surfaces.
3. Installing the oil seal
1) Coat the surface to which the oil seal is to be
applied with a lubricant or grease.
+ If the lip should double over as the oil seal is
being fitted over the shaft, return it to its
proper place by rotating the shaft and
pulling the oil seal slightly backwards.
2) When installing an oil seal on a shaft machined
with a keyway, splines, or threads, use a
suitable jig to protect the lip.
3) Use a suitable press to press fit the oil seal into
the housing.

5. Applying adhesives
Take special care when applying adhesives. to the
outer surface of oil seals. Adhesive on the surface
of the lip or shaft leads to oil leakage.
* Since any adhesives on the surface of the press
jig will soon transfer to the oil seal lips, clean
the jig before use.
2. FLOATING SEALS
1. Handling floating seals
1) Keep each pair of floating seals bundled
together with tape to avoid mix-ups when they
are reinstalled.
2) Discard the old O-rings. Always use new ones
when installing the floating seals.
3) Replace a floating seal if its contact surface is
rusted.
2. Installing floating seals
1) Remove all rust and dust from the mounting
surfaces of the seal. Use sandpaper to remove
any rust that might come into contact with the
O-ring.
2) When installing the floating seal, coat the
mounting surfaces with oil. Then install the

3. Precautions for using liquid gasket
1) Remove all scratches, dirt, paint, grease and old
gasket sealant before applying a new coat.
2) Coat the specified area evenly and let dry for
several minutes.
3) Assemble the mating parts when the gasket
sealant is stickly to the touch.
5. BEARINGS
1. Handling bearings
1) Shield the bearings from dust and dirt; even
the tiniest speck rapidly accelerates wear.
+ Leave the bearings in their protective
packaging until just before they are to be
installed.
2) Protect a bearing from excessive force and
shocks.
* Never dry a bearing with compressed air
after cleaning.
2. Installing bearings
I) Never drive a bearing onto a shaft by pounding
on the outer race or into an opening by
pounding on the inner race. Such pounding
produces dents in the tracks in the races.

B Precautions for servicing the work equip-
ment hydraulic system
I) Lower the work equipment to the ground and
turn off the engine.
2) Loosen the oil filler cap to relieve pressure in
the hydraulic oil tank.
3) Operate the control levers 2 or 3 times to
eliminate hydraulic pressure remaining in the
piping to be disassembled.
4) Support the work equipment on a stand to
prevent it from falling when the piping is
removed and the hydraulic pressure is released.
1. Removing the hydraulic piping
1) Disconnect hydraulic tubes from hoses or other
tubes by holding the nut on the spigot (the
male side of the joint) with a wrench while
loosening the one on the socket (the female
side).
FSO044 7)
2) Seal the ends of the disconnected tubes and
hoses and the oil ports to the hydraulic
equipment with blind plugs to keep out foreign
matter. For the same reason, seal the ports of
the hydraulic tank with adhesive tape.
3) Have appropriately-sized containers under-
neath to catch the hydraulic fluid that will flow
out when the piping is disconnected. Clean up
all spills immediately.
4) When working under the machine, position
yourself out of the way of the oil shower.
5) Tag the ends of all piping removed as well as
the ports to which they were attached.

traces of detergent with compressed air.
Repair the sealing faces or, if the scratches and
dents are too large, replace.
Do not use gasket sealant for hydraulic piping!
Install the piping so that alt the identification
tags match.
When a pipe must be joined at both ends,
tightening only one end at a time may make it
too short. First fit both ends by hand and then
tighten the ends by turns. (See figure.)
Tighten gradually and alternately
the both ends.
FSO045
To ensure tight-fitting seals, tighten the nuts to
80% of the specified torque, loosen 90°, and
then tighten to the full torque.
After completing all connections, run the
engine at idling speed and operate all the
control levers of the hydraulic attachments.
Then check the oil level in the hydraulic tank

the surroundings, but the high flow rate may
also damage the O-ring of the coupling.
2) Never use a hammer to tighten or loosen a
coupling.
* Such sharp blows can deform the coupling,
leading to oil leakage or cracking of the
coupling.
3) Protect the disconnected piping from the
intrusion of dust and dirt ! If it is to remain

A Heavy parts (25 kg or more) must be lifted
with a hoist etc. In the Disassembly and As-
sembly section, every part weighing 25 kg or
more is indicated clearly with the symbol &
1. If a part cannot be smoothly removed from the
machine by hoisting, the following checks should
be made:
l Check for removal of all bolts fastening the
part to the relative parts.
. Check for existence of another part causing
interference with the part to be removed.
2. Wire ropes
I) 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
maximum strength at the middle portion.
100% 88% 79% 71% 41%
FSOO64
3) Do not sling a heavy load with one rope alone,
but sling with two or more ropes symmetrically
wound on to the load.
Q
( 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 (kg) when
hoisting is made with two ropes, each of which
is allowed to sling up to 1000 kg vertically, at
various hanging angles.
When two ropes sling a load vertically, up to
2000 kg of total weight can be suspended.This
weight becomes 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 4000 kg if they sling a 2000 kg
load at a lifting angle of 150”.

7) When using a hoist to turn over a heavy part,
observe the following instructions:
l Clear as much of the area surrounding the
part as possible.
. When turning the part over, take special care
to prevent the ropes from slackening and the
part from slipping when the center of gravity
changes.
. Gradually slacken the wire ropes after
making sure that the part is completely
turned over.
Slackening the ropes before complete
turning of the part may cause the part to fall
back to its original position.

* The following precautions are necessary when using the Standard Value Tables to make judgement during trouble-
shooting or during testing and adjusting.
1. The values in these tables are based on the values for new machines leaving the plant, so they should be used
as target values when repairing or when estimating wear after a period of use.
2. The standard values in these tables for judgement when troubleshooting are estimated values based on the
standard values for the machine when shipped from the plant, and on the results of various tests.
Therefore, they should be used as reference in combination with repair and operating records when making
judgements.
3. These standard value tables must not be used for standard values when judging claims. In addition, do not use
these values alone to make simple judgements.

Qf When taking measurements, be careful not to touch
the exhaust manifold or muffler, or to get caught
in rotating parts.
1. Measuring blow-by
When measuring the blow-by, warm the engine
up thoroughly.
Stop engine and install adapter of blow-by
checker on engine breather hose (1).
Connect adapter and blow-by A (0 to 500
mmH,O) to hose.
Run the engine at high idling and measure the
blow-by pressure.
2. Precautions when measuring blow-by
* The blow-by should be measured with the
engine running at rated output.
- When measuring in the field, a similar value
can be obtained at stall speed.
- If it is impossible to check at rated output
or stall speed, measure at high idling.
In this case, the blow-by value will be about
80% of the value at rated output.
* Blow-by may vary greatly according to the
condition of the engine, so if there is any ab-
normality in the reading, check for any prob-
lem related to defective blow-by, such as ex-
cessive oil consumption, defective exhaust
gas color, or early deterioration or contami-
nation of the oil.
