Actions before starting a new hydraulic system

IMPORTANT!

When installing hydraulic hoses and filling hydraulic oil, the following applies:

• Check the manufacturer's specifications for the hydraulic pump before commis-sioning the hydraulic pump.

• Make sure that the entire hydraulic system is clean before filling with the recom-mended hydraulic oil. More information can be found under the heading Hydrau-lic oil.

• Ensure sufficient lubrication by making sure that the hydraulic pump is filled to at least 50% before it is started.

The hydraulic system is tested and ready for start without any preparatory action on vehicles factory-fitted with the following specifications:


• Controls in the cab

• Filled hydraulic oil tank

In the following cases, the hydraulic system requires a test drive:

• Vehicles factory-fitted without controls in the cab

• Vehicles factory-fitted with complete hydraulic systems without filled hydraulic oil tanks

Example of ball valve in open position.

Hydraulic oilIMPORTANT!

There is a risk of breakdown if the system is started without oil. Therefore, ensure the following before starting:

• Check the level indicator in the hydraulic oil tank, top up if necessary

• The ball valve for the low pressure hose must be open

• The hydraulic pump must be filled with hydraulic oil to more than 50%

IMPORTANT!

For filling, use only hydraulic oil that complies with ISO 11158 HV, DIN 51524. Avoid mixing different hydraulic oils because its properties may be impaired due to chemical reactions between different additives.

IMPORTANT!

The hydraulic oil must satisfy the purity requirements in accordance with ISO 4406, code 20/18/13.


Hydraulic oil tank

Hydraulic equipment

IMPORTANT!

The purity of the hydraulic oil has a direct influence on the service life of the hydrau-lic system. Regularly renew the oil and air filters and change the hydraulic oil to achieve a long service life for the hydraulic pump. To obtain the longest possible ser-vice life, Scania recommends a filtration of 10 µm (absolute separation efficiency). The filter captures 100% of particles larger than 10 µm. Only use hydraulic oils with anti-foaming agents and anti-wear inhibitor.

A dirty air filter means an increased risk of dirt being sucked into the tank. This can also result in impaired venting and a risk of vacuum in the tank, which can lead to hydraulic equipment being damaged.

The hydraulic oil tank should be filled with 50% more hydraulic oil than the nominal pump flow per minute. Certain applications with a short working cycle can be ex-cluded from this rule, for example a one-way tipper truck that is used less frequently and where the hydraulic oil has time to cool down.

Hydraulic equipment

Connection to hydraulic valveNote:The hydraulic valve cannot be used for a double-action cylinder that requires pres-sure in 2 directions.

Note:Put the hydraulic valve in the closed position when loading, otherwise the tipping cylinder may be damaged by heavy impact from, for example, rock mass.

When the hydraulic valve is in neutral, the oil goes from the hydraulic pump directly to the tank. When the valve is opened, the oil flow is directed out to port A1 or port C2, see table, and the tipping cylinder moves upwards. If the valve is put in neutral while the tipping cylinder is moving upwards, the tipping cylinder stops. When the valve is closed, port A1 or port C2 function as a return port and the return flow is di-rected back to the hydraulic oil tank. The tipper body tare weight makes the hydraulic piston move inwards in the cylinder.

The hydraulic valve can only control single-action functions, for example a single-action tipping cylinder that is pressed together in the return movement using the tip-per body's dead weight. The hydraulic valve can also be used to provide system pres-sure/system flow to another hydraulic valve on the truck or trailer bodywork.

Hydraulic pumpNote:The suction coupling and pressure coupling are not included when the hydraulic pump is ordered. The parts are included in the option Hydraulic hose between tank and pump, with (variant code 6645A).

The engine speed is limited when the power take-off is activated on vehicles factory-fitted with the options Hydraulic pump for wet kit, with (variant code 4801A) and Hy-draulic hose between tank and pump, with (variant code 6645A). Engine speed lim-itation ensures that the hydraulic pump is not overloaded. The limited engine speed depends on the hydraulic pump and power take-off with which the vehicle is fitted.

Activating the hydraulic pumpTo protect against unintentional operation of the hydraulic pump, the air pipe that ac-tivates the hydraulic pump is not connected at the factory. Complete the installation by connecting the air pipe to the hydraulic pump; see illustration.

The air pipe is connected to vehicles that have the following factory-fitted equip-ment:


• Filled hydraulic oil tank

• Controls in the cab


Hydraulic pump

Hydraulic equipment

Hydraulic oil flow and engine speedNote:The engine speed affects the performance of the hydraulic system. Check with the pump supplier that the engine speed results in the correct hydraulic oil flow.

Note:On vehicles factory-fitted with hydraulic system assemblies, there is a risk that the hydraulic pump will be damaged by cavitation if the engine speed exceeds the facto-ry-set limit.

In the event that a hydraulic system other than the one with which the vehicle was fitted at the factory is connected, the engine speed limitation requirements change.

All vehicles factory-fitted with the options Hydraulic pump for wet kit, with (variant code 4801A) and Hydraulic hose between tank and pump, with (variant code 6645A) have a factory-set engine speed limitation in the event of power take-off activation. It is possible to change the engine speed limitation.

Calculation example hydraulic pump flowIt is important that the hydraulic pump has the correct capacity to avoid overloading the power take-off and to ensure the correct flow capacity with the selected engine speed.

The hydraulic pump’s capacity D in cm3/revolution is calculated using the following formula:

Description of parameters:

• Q = pump flow required (l/min)

• D = hydraulic pump offset (cm3/rev)

• N = selected engine speed (rpm)

• Z = power take-off gear ratio

• ηv = the hydraulic pump's volumetric efficiency, i.e. the pump's actual displace-ment divided by its theoretical displacement (1 = 100% efficiency)

Example:

Power take-off EG650P has a gear ratio (Z) of 1.24. Scania expects a hydraulic pump with the following properties:

• Hydraulic pump offset (D): 80 cm3/rev

• Engine speed limitation (N): 1 200 r/min

• Volumetric efficiency (ηv): 0.97

Q =D × N × Z × ηv

1,000

Q =80 × 1,200 × 1.24 × 0.97

= 115 l/min1,000


Hydraulic hoses and couplings

Hydraulic equipment

Hydraulic hoses and couplingsFor the installation of hydraulic hoses and couplings, Scania's requirements must be satisfied. The requirements have been developed to ensure that the hydraulic system and other equipment are exposed to the least possible stress and wear during use.

Tractors can be fitted with hydraulic hoses with quick release couplings at the facto-ry.

Diameter of high pressure hose and return hose is 1 inch; maximum permissible op-erating pressure is 250 bar (25 MPa). The high pressure hose and return hose have a G1 inch BSPP thread with a 60o cone.

The diameter of the low pressure hose is 2 inches, and the connection on the tank has a 1.5 inch BSPP thread with a 60o cone.
