Example of wet kit from the factory
GeneralIt is possible to order components from the factory for operating hydraulic equip-ment.
The following components are available:
• Control
• Hydraulic oil tank with pressure limiting valve
• Hydraulic pump
• Hoses and couplings
Actions before starting a new hydraulic systemFor vehicles that have been ordered with a complete system with hydraulic oil from the factory, the system has already been test run.
IMPORTANT!
When installing your own hoses and filling with your own oil, the following must be ensured:
• Check that the entire hydraulic system is clean before filling with a recommended hydraulic oil.
• The pump must be filled to at least 50% before it is started as the leakage flow is insufficient to lubricate an empty pump.
• Fill with hydraulic oil for the pump by using a funnel via the drainage port.

Control
Ordering individual componentsControlIt is possible to order a control for operating bodywork equipment such as a tipper body.
The control is fitted at the factory, either in the forward or rearward lever position. In the forward position, the platform is tipped by pushing the control forwards and in the rearward position the platform is tipped by pulling the control backwards.
Ordering options
For vehicles ordered with the control fitted at the factory, plastic pipes are connected to the control and routed out on the chassis behind the gearbox.
For vehicles ordered with preparation for the control, 5 x 6 mm plastic pipes are rout-ed out to the chassis frame’s third crossmember, from the location for the control be-tween the driver’s seat and rear door pillar. The preparation does not include the control.

Preparation for control
Preparation for right-hand drive vehicles with P cabFor right-hand drive vehicles with P cabs it is possible to order preparation for the control for operating the tipper body. The following is included in the preparation:
• In the location for the control between the driver’s seat and rear door pillar are 2 x 6 mm plastic pipes. The plastic pipes are routed to the right-hand side of the frame, rearwards to the first crossmember behind the gearbox.
• A bracket for the control is fitted in the cab.
The preparation is ordered as FFU.

More information on Customised symbols and colours is found in the document Bod-ywork interface.
Indicator lamp preparationThe indicator lamp can be ordered as FFU.
Preparations include the following:
• Trucks: A two-conductor cable is coiled and placed on a crossmember behind the gearbox. The electrical cable is marked with the part number 1 421 484.
• Tractors: The function is prepared in the trailer connection on pin 10.
When the conductors have contact with each other, the indicator lamp lights in the instrument panel and a continuous warning sound is heard in the cab. The indicator lamp’s colour and warning sound can be changed using SDP3. This can, for example, be used to give an indication that the platform is raised on a tipper truck. The symbols in the instrument panel are interchangeable.

Valve with fixed pressure

Valve with adjustable pressure
Pressure limiting valveSelect a pressure limiting valve when ordering a tank.
The pressure limiting valve is delivered fitted on the hydraulic oil tank’s upper side from the factory. The delivery valve functions as a pressure limiter and has an on and off function. If the valve is connected to a single-action cylinder (for example dump-ing) the hose is connected to port A. When the valve is open, the oil flow is led out to port A. When the valve then closes, port A functions as a return port and the return flow is led back to the hydraulic oil tank.
If the valve is connected to a double-action cylinder or a hydraulic motor then the pressure function is connected to port A and the return hose to port T.
The delivery valve can be ordered with 4 fixed positions or with adjustable pressure limitation. The 4 fixed positions are as follows:
• 150 bar
• 170 bar
• 190 bar
• 220 bar
For valve with adjustable pressure limitation there are 2 positions, 150 or 220 bar. Preset pressure from the factory is 150 bar.
The pressure limiting valve is available in the following versions:

Not activated connection
Hydraulic pumpIt is a prerequisite that one of the following power take-offs, EG650P, EG651P, EG652P or EG653P, is ordered if a hydraulic pump is to be fitted at the factory.
When ordering a pump from the factory, the engine speed is limited when the power take-off is activated. The speed depends on the pump and power take-off selected.
• The suction union and pressure connection are not included when the pump is or-dered but must be ordered separately.
• Pump activation is not connected at delivery. Connect the P-pipe to complete the installation.

Hoses with swivel joint
Complete installation from the factoryTo get a complete installation from the factory, selected parts of special components must be ordered together with the following components:
• Hoses and couplings
• Hydraulic oil
Hoses and couplingsHoses with quick release couplings can be ordered from the factory.
The diameter of the pressure and return hoses is 1 inch and the maximum working pressure is 250 bar.
The diameter of the suction hose is 2 inches.
Hoses should be ordered using variant code 4837A after the hydraulic pump and pressure limiting valve options have been selected.
When ordering the hoses, also hoses between the hydraulic pump and tank are deliv-ered.
When the hoses are ordered it is possible to select the following:
• Coupling position and hose attachment
• With or without return hose
• Type of hose coupling
Use swivel joint in order for the hydraulic hoses to move without the risk of strain even at extreme angles between the tractor and semi-trailer.

Ball valve
Recommendations for hydraulic oil are available in the document General informa-tion about power take-offs.
Hydraulic oilHydraulic oil can be ordered after ordering the hoses using variant code 4837A and when the hydraulic pump and pressure limiting valve options have been selected.
The hydraulic oil supplied from the factory is Q8 Heller VG 22.
Note:There is a risk for breakdown if the system is started without oil. Therefore, check before starting:
• That there is oil in the hydraulic oil tank (using the level indicator).
• Check that the ball valve for the suction pipe is open.
To achieve a good service life of the hydraulic pumps, it is important to renew the oil filter regularly and also change the hydraulic oil when necessary. The purity of the oil is directly related to the service life of the hydraulic system. To obtain the longest possible service life, Scania recommends a filtration of 10 µm (abs). Only use hy-draulic oils with anti-foaming and anti-wear additives.
Examples of tipper functions: With an ambient temperature of 35°C the hydraulic oil’s temperature becomes approx. 40°C for dumping. Hydraulic oil VG22 has 22 mm2/s (cSt) and therefore lies between 20 and 30 mm2/s (cSt).
A hydraulic oil with too high viscosity can cause the hydraulic system to be experi-enced as being sluggish as the oil must reach operating temperature before it becomes more viscous. This applies primarily to functions that are used in short cycles, for ex-ample dumping.

ViscosityThe hydraulic oil supplied from the factory is of the Q8 Heller VG22 type. When fill-ing your own oil, you should select VG32 for hot climates and VG22 for cold cli-mates. However, for dumping VG22 is quite sufficient also in hot climates as it does not have time to build up heat in the hydraulic system. For a tipper truck, the hydrau-lic oil normally has a 5°C higher temperature than the ambient temperature. For Sca-nia’s pumps, a viscosity of between 20 and 30 mm2/s (cSt) is recommended.
