determine the problem area.
Determine the Problem Area
1. Stop the power unit hydraulic oil flow. Disconnect
the existing tool from the hoses and power unit.
2. Connect a known working tool to the hoses and
power unit. See the tool’s operator’s manual for
correct hookup procedure. Start the power unit
hydraulic oil flow.
If the known working tool operates, the problem is in
the disconnected tool. See the tool operator’s
manual for troubleshooting.
If the known working tool does not operate, the
problem is likely to be in the hoses or the power
unit. Proceed to Step 3.
3. Stop the power unit hydraulic oil flow. Disconnect
the existing hoses from the known working tool and
power unit.
4. Connect a different set of hoses to the known
working tool and power unit. Start the power unit
hydraulic oil flow.
If the known working tool operates with the different

SELECTION, INSTALLATION AND MAINTENANCE OF
HOSE AND HOSE ASSEMBLIES
- SAE J1273 MAY 1986*
SAE RECOMMENDED PRACTICE
The following recommendations on selection, installation
and maintenance of hose and hose assemblies was
established by the S.A.E. in 1979 and reaffirmed May
1986. Please read these general instructions carefully.
1. SCOPE
Hose (also includes hose assemblies) has a finite life and
there are a number of factors which will reduce its life.
This recommended practice is intended as a guide to
assist system designers and/or users in the selection,
installation, and maintenance of hose. The designers and
users must make a systematic review of each application
and then select, install, and maintain the hose to fulfill the
requirements of the application. The following are general
guidelines and are not necessarily a complete list.
Improper selection, installation or maintenance
may result in premature failures, bodily injury, or
property damage.
2. SELECTION
The following is a list of factors which must be considered
before final hose selection can be made.
2.1 Pressure - After determining the system pressure,
hose selection must be made so that the recommended
maximum operating pressure is equal to or greater than
the system pressure. Surge pressures higher than the
maximum operating pressure will shorten hose life and
must be taken into account by the hydraulic designer.
2.2 Suction - Hoses used for suction applications must be
selected to insure the hose will withstand the negative
pressure of the system.
2.3 Temperature - Care must be taken to insure that fluid
and ambient temperatures, both static and transient, do
not exceed the limitations of the hose. Special care must
be taken when routing near hot manifolds.
2.4 Fluid Compatibility - Hose selection must assure
compatibility of the hose tube, cover, and fittings with fluid
used. Additional caution must be observed in hose selection for gaseous applications.
2.5 Size - Transmission of power by means of pressurized fluid varies with pressure and rate of flow. The size of
the components must be adequate to keep pressure
losses to a minimum and avoid damage to the hose due to
heat generation or excessive turbulence.
2.6 Routing - Attention must be given to optimum routing
to minimize inherent problems.
2.7 Environment - Care must be taken to insure that the
hose and fittings are either compatible with or protected
from the environment to which they are exposed. Environmental conditions such as ultraviolet light, ozone, salt
water, chemicals, and air pollutants can cause degradation and premature failure and, therefore, must be considered.
2.8 Mechanical Loads - External forces can significantly
reduce hose life. Mechanical loads which must be considered include excessive flexing, twist, kinking, tensile or
side loads, bend radius, and vibration. Use of swivel type
fittings or adapters may be required to insure no twist is
put in the hose. Unusual applications may require special
testing prior to hose selection.
2.9 Abrasion - While a hose is designed with a reasonable level of abrasion resistance, care must be taken to
protect the hose from excessive abrasion which can result
in erosion, snagging and cutting of the hose cover.
Exposure of the reinforcement will significantly accelerate
hose failure.
2.10 Proper End Fitting - Care must be taken to insure
proper compatibility exists between the hose and coupling
selected based on the manufacturer’s recommendations
substantiated by testing to industry standards such as
SAE J517d (November, 1976).
2.11 Length - When establishing proper hose length,
motion absorption, hose length changes due to pressure,
as well as hose and machine tolerances must be considered.
2.12 Specifications and Standards - When selecting hose,
government, industry, and manufacturer’s specifications
and recommendations must be reviewed and applicable.
2.13 Hose Cleanliness - Hose components vary in
cleanliness levels. Care must be taken to insure that the
assemblies selected have an adequate level of cleanliness for the application.
2.14 Electrical Conductivity - Certain applications require
that the hose be non-conductive to prevent electrical
current flow. Other applications require the hose to be
sufficiently conductive to drain off static electricity. Hose
and fittings must be chosen with these needs in mind.

Appendix A (cont’d)
3. INSTALLATION
After selection of proper hose, the following factors must
be considered by the installer.
3.1 Pre-Installation Inspection - Prior to installation, a
careful examination of the hose must be performed. All
components must be checked for correct style, size, and
length. In addition, the hose must be examined for cleanliness, I.D. obstructions, blisters, loose cover, or any other
visual defects.
3.2 Follow Manufacturers’ Assembly Instructions.
3.3 Minimum Bend Radius - Installation at less than
minimum bend radius may significantly reduce hose life.
Particular attention must be given to preclude sharp
bending at the hose/fitting juncture.
3.4 Twist Angle and Orientation - Hose installations must
be such that relative motion of machine components
produces bending of the hose rather than twisting.
3.5 Securement - In many applications, it may be necessary to restrain, protect, or guide the hose to protect it from
damage by unnecessary flexing, pressure surges, and
contact with other mechanical components. Care must be
taken to insure such restraints do not produce additional
stress or wear points.
3.6 Proper Condition of Ports - Proper physical installation
of the hose requires a correctly installed port connection
while insuring that no twist or torque is put into the hose.
3.7 Avoid External Damage - Proper installation is not
complete without insuring tensile loads, side loads, kinking,
flattening, potential abrasion, thread damage, or damage
to sealing surfaces are corrected or eliminated.
3.8 System Check Out - After completing the installation,
all air entrapment must be eliminated and the system
pressurized to the maximum system pressure and checked
for proper function and freedom from leaks.
Note: Avoid potential hazardous area while testing.
4. MAINTENANCE
Even with proper selection and installation, hose life
may be significantly reduced without a continuing maintenance program. Frequency should be determined by the
severity of the application and risk potential.
A maintenance program should include the following as a
minimum.
4.1 Hose Storage - Hose products in storage can be
affected adversely by temperature, humidity, ozone,
sunlight, oils, solvents, corrosive liquids and fumes,
insects, rodents and radioactive material. Storage areas
should be relatively cool and dark, and free of dust, dirt,
dampness and mildew.
4.2 Visual Inspection - Any of the following conditions
requires replacement of the hose:
(a) Leaks at fitting or in hose. (Leaking fluid is a fire
hazard).
(b) Damaged, cut or abraded cover. (Any reinforcement
exposed).
(c) Kinked, crushed, flattened or twisted hose.
(d) Hard, stiff, heat cracked or charred hose.
(e) Blistered, soft degraded or loose cover.
(f) Cracked, damaged, or badly corroded fittings.
(g) Fitting Slippage on hose.
4.3 Visual Inspection - The following items must be
tightened, repaired, or replaced as required:
(a) Leaking port conditions.
(b) Clamps, guards, shields.
(c) Remove excessive dirt buildup.
(d) System fluid level, fluid type, and any air entrapment.
4.4 Functional Test - Operate the system at maximum
operating pressure and check for possible malfunctions
and freedom from leaks.
Note: Avoid potential hazardous areas while testing.
4.5 Replacement Intervals - Specific replacement inter-
vals must be considered based on previous service life,
government or industry recommendations, or when
failures could result in unacceptable down time, damage,
or injury risk.
