1. All pipes and tubing must be thoroughly cleaned before installation. Recommended methods of cleaning are sand
blasting, wire brushing, and pickling.
2. To minimize flow resistance and the possibility of leakage, only as many fittings and connections as are necessary
for proper installation should be used. The minimum hose or tubing diameter should not be less than the connecting
SAE opening of the transmission.
3. The number of bends in tubing should be kept to a minimum to prevent excessive turbulence and friction of oil flow.
Tubing must not be bent too sharply. The recommended radius for bends is three times the inside diameter of the
tube.

GENERAL DATA
Oil in a hydraulic system performs the dual function of lubrication and transmission of power. It constitutes a vital factor
in a hydraulic system, and careful selection of it should be made with the assistance of a reputable supplier. Proper
selection of oil assures satisfactory life and operation of system components with particular emphasis on hydraulic
pumps. Any oil selected for use with pumps is acceptable for use with valves or motors.
CLEANLINESS
Thorough precautions should always be observed to insure the hydraulic system is clean:
1. Clean (flush) entire new system to remove paint, metal chips, welding shot, etc.
2. Filter each change of oil to prevent introduction of contaminants into the system.
3. Provide continuous oil filtration to remove sludge and products of wear and corrosion generated during the life of the
system. The maximum contamination level should be less than three (3) milligrams/100 milliliters.
4. Provide continuous protection of system from entry of airborne contamination by sealing the system and/or by proper
filtration of the air.
5. During usage, proper oil filling and servicing of filter, breathers, reservoirs, etc., cannot be over emphasized.
6. Thorough precautions should be taken by proper system and reservoir design, to insure that aeration of the oil will be
kept to a minimum.
SOUND LEVEL
Noise is only indirectly affected by the fluid selection, but the condition of the fluid is of paramount importance in
obtaining optimum reduction of system sound levels.
Some of the major factors affecting the fluid conditions that cause the loudest noises in a hydraulic system are:
1. Very high viscosities at start-up temperatures can cause pump noises due to cavitation.
2. Running with a moderately high viscosity fluid will impede the release of entrained air. The fluid will not be
