GENERAL

Bolts and Nuts (for ISO Strength Category 10.9)

1. General Tightening Points (Non-lubricated)

• All securing points other than the special

tightening points.

2. Special Tightening Points (Grease with molyb-

denum disulﬁde applied.)

• Points where particularly necessary due to

function.

Special tightening positions and associated

instructions are given in the text.

3. Points where thread-locking compound is used

(Three Bond #1324 is applied.)

Thread-locking compound positions and associ-

ated instructions are given in the text.

4. If tightening torque values are provided in this

manual, then tightening should be done accord-

ing to those values.

(This indicates that the tightening torque differs

from the values given in this table.)

5. In order to tighten bolts and nuts evenly, they

should be tightened alternately top, bottom, left,

right.

SPECIFICATIONS

In regard to Standard Values and Allowable Values

The terms used in the items “Servicing Standards” and “Standards for Judging Performance” have the following
meanings.

Standard Value ............ This indicates the standard value for the new machine at the time of shipping from the

factory. It should be used as the target value for maintenance work after operation.

Allowable Value .......... The dimensions of parts change during use because of wear and deformation. Also, the

performance of pumps, motors, and other hydraulic equipment drops, and this is the
estimated value indicating the use limit for the respective part. It is decided under refer-
ence to the standard at the time of shipping, the results of various tests, etc. As the use
conditions, the degree of repairs, etc., differ for each machine, these should be combined
and used as reference for servicing standards and standards for judging performance.
* Do not use the standard values and the allowable values as standards for customer

claims.

RECOMMENDED LUBRICANTS

Select the appropriate fuel, lubricant and grease according to the temperature by referring to the table below.

• Regardless of the speciﬁed time, change the oil if it becomes too dirty or degraded.

• When reﬁlling, never mix oils of different brands. If a brand is to be changed, replace the whole fuel/oil.

*: For water, use tap water (soft). Do not use well or river water.

When the ambient temperature drops below 0°C, add coolant (antifreeze). Follow the coolant manufacturerʼs

instructions to determine the mixture ratio.

**: The replacement interval for hydraulic oil depends on the oil type being used. New machines are shipped

from the factory with the Takeuchi genuine hydraulic oil 46. This manual describes when to replace the

hydraulic oil assuming that this Takeuchi oil 46 is used. When a conventional antiwear hydraulic oil is used,

replace it every 2000 hours.

Diesel fuel standards

Use the diesel fuel that is compliant with any of the
standards below. The table below shows the stan-
dards from the various countries.

Part

Type

Capacity

Fuel tank

Desel fuel

To keep the performance and service life of the engine, al-
ways use the clean and high-quality fuel.

•

To avoid freezing in cold climates, use a light oil that still

functions when the temperature is at least 12°C below the
lowest expected ambient temperature.

•

Use a light oil that has a cetane number of 45 or higher.

When operating at a very low temperature or at a high
altitude, a higher cetane number fuel will be required.

•

The sulfur content must be less than 0.5% by volume. he

recommended value, however, is less than 0.05%. The
electronically-controlled engine with an EGR system
should use fuel containing less than 0.05% sulfur.

Fuel containing a high content of sulfur may cause sulfu-

ric acid corrosion inside the cylinder.

•

Do not mix diesel fuel with any kerosene, used engine oil

or leftover fuel.

•

Poor quality fuel can degrade the engine performance. It

also can damage the engine.

•

Avoid using additives to fuel. Some fuel additives can

degrade the engine performance.

METHODS FOR INSPECTING PERFOR-

MANCE

Hydraulic Oil Pressure (Main Relief Valve

Set Pressure)

Travel, Boom, Arm

Measuring Method

• Engine

: Maximum r.p.m.

• Hydraulic Oil Temp. : 50~60°C

• Mount the pressure gauge on the pressure detec-

tion port, operate the desired hydraulic circuit and

measure the relief pressure.

Adjusting Method

Travel circuit (High pressure set)

1. Loosen the lock nut (1).

2. Fasten the plug (2) until the piston (3) contacts

the surface A of the plug (4).

• Be sure that the plug (4) does not turn together

with the plug (2).

• The tightening torque of the plug (2) is

19.6N·m or less.

• The size B is 4 mm or more.

3. Turn the plug (4) and adjust the set pressure.

• Turn the plug slowly by referring to the pres-

sure gauge.

• The pressure increases by 21.3 MPa at one

turn of the plug.

4. Upon completion of the pressure adjustment,

hold the plug (4) to prevent it from turning and

fasten it with the lock nut (5).

Boom and Arm Circuits (Low pressure set)

5. First, set the travel circuit (high pressure set),

then loosen the plug (2) and adjust the set pres-

sure.

• Turn the plug slowly by referring to the pres-

sure gauge.

• The pressure decreases by 21.3 MPa at one

turn of the plug

6. Upon completion of the pressure adjustment,

hold the plug (2) to prevent it from turning and

fasten it with the lock nut (1).

7. Actuate the relief valve again and conﬁrm that

the set pressure is stable.
