When the wheel motor is equipped with dynamic brake (drum brake, output flange DB), and when handbrake is needed, customer needs to specify an additional information on the ordering code. Infact, the wheel motor can be positioned on the left or right side. Refer to the below scheme for better understanding. Contact Italgroup for further information/requests.

Dynamic brake is usually operating with brake fluid (like DOT 3 or DOT 4); if you want to activate dynamic brake with other fluids (like hydraulic motor fluid for example, see fluid recommendations), specify it into the order or contact Italgroup for further information.

Installation Hoses and piping must be clean and free from contamination. No other special requirements are necessary.- Motor can be mounted in any position- In run-away conditions you must use counterbalance valves- Consult factory for intermittent applications

Splined adaptors (sleeves) are available upon request.

Installation circuit The choice of open or closed loop circuit will be determined by the ap-plication. Open loop circuits are cheaper and simpler to install. Closed loop circuit is a superior circuit and usually takes up less space. It also offers better control features.

Start up Motor case and pistons must be completely filled with oil before starting. Do not load motor to maximum working pressure instantly. During cold start-up avoid high-speed operation until the system reach the working temperature.

Case Drain – Case Pressure Connect the case drain directly to tank. The case drain port on the motor must be located on the highest point of the installation to ensure that the motor will always be full of oil. The case drain pressure must not exceed 6 bar continuous pressure. (See drain recommendations page for more details)

Important When the motor is installed vertically with shaft pointing upwards, con-sult our Technical Department. If the motor is connected to high inertial loads, the hydraulic system must be designed to prevent peaks of pressu-re and cavitation.

Temperature Maximum oil temperature must not exceed 70°C (Please refer to hy-draulic fluid recommendations). Heath exchangers must be used with higher temperatures.

Viscosity The motor works satisfactory in a range of 3°E to 10°E oil viscosity. Best performance is obtained at the highest viscosity. (Please refer to hydraulic fluid recommendations)

Back Pressure Don’t exceed 70 bar back pressure.

HYDRAULIC MOTOR INSTRUCTIONS AND ADVICES

Minimum speed W series wheel motors can reach very low operational speeds, depen-ding by motor displacement, ambient and working conditions. Applying a reasonable back pressure the minimum speed can be reduced. For more information please contact our technical department.

Flushing The operating fluid viscosity must always be higher than a certain minimum value (see “fluid recommendation” section) in order to guarantee an optimal motor internal lubrication. When the working conditions cause the motor case overheating above a critical value, the motor flushing is required. Flushing consists in the introduction of fresh oil (taken from the hydraulic circuit) into the motor case. Oil must be taken from the return line to avoid internal motor damage (the con-tinuous motor case pressure must be maximum 6 bar). Flushing is an important operation that can be very effective to improve motor lifetime with heavy duty working conditions and improve the motor mechanical efficiency. Italgroup can provide you flushing valves in order to perform an effective flushing circuit.

For more details on the above mentioned arguments and for any further information please contact our technical department.

GEAR UNIT INSTRUCTIONS AND ADVICES

The gear unit maintenance requires the periodic change of the oil and the lubrificant level monito-ring. We advice to change the oil before 100 hours (during the gear unit running-in), and every 800

hours, and at least one time par year.The recommended gear unit mineral oils are the

following:AGIP BLASIA 220

SHELL OMALA EP 220BP ENERGOL GR-HP 220

ESSO SPARTAN EP 220ELF REDULTELF SP 220

MOBIL MOBILGEAR 630To fill the gear unit with lubrificant it is necessary rotate the group to let the two plugs to be in the

correct position (see fig.1). After this the two plugs must be removed and the gear unit must be filled

with mineral oil until the oil will flows out from the upper plug hole.

To remove the gear unit lubrificant it is necessary rotate the group to be in the correct position (see fig. 2). After this the two plugs must be removed; this will let the mineral oil flows out easily. To do this operation in the most easy way the oil must

be warm. A frequent oil level checking it is recom-mended. It is a good rule do this check every 80 working hours. Assure that the system it is clean

before start the unit it is compulsory.

HYDRAULIC MOTOR FLUID RECOMMENDATIONS

Fluid selection In general, we recommend the use of hydraulic oils with minimum viscosity index of 95, with anti-wear additives (ISO HM and HV). Once normal working temperature is reached, the drain oil viscosity must be at least 44 cSt, preferably in the range from 50 to 80 cSt. HE oils (ecological fluids) are allowed, but must be used with particular atten-tion, because them can influence the motor seals compatibility, and can reduce motor performances and life. Please contact us in case of HE oils usage.

Optimal viscosity selection Referring the first approximated selection to the room temperature, we advice the following:

Room temperature Oil-20°C/0°C BP ENERGOL HLP – HM 22

-15°C/+5°C BP ENERGOL HLP – HM 32-8°C/+15°C BP ENERGOL HLP – HM 460°C/+22°C BP ENERGOL HLP – HM 68

+8°C/+30°C BP ENERGOL HLP – HM 100-20°C/+5°C BP BARTRAN HV 32

-15°C/+22°C BP BARTRAN HV 460°C/+30°C BP BARTRAN HV 68

ATF (automatic transmission fluid) oils, SAE 10-20-30 W oils, multi-grade motor oils (SAE 15 W 40, 10 W 40), universal oils, can also be used. Always fill the motor (please refer to the “DRAIN RECOMMENDA-TIONS” section) with the selected hydraulic fluid before motor start-up. During cold start-up avoid high-speed operation until the system rea-ch the working temperature, in order to provide an adequate lubrication.Every 5-8 °C of increase respect to the optimal working temperature for the se-lected oil, the hydraulic fluid life decrease of about 40-50% (refer to “OXIDATION” section). Consequently, the motor lifetime will be affected by the working tem-perature increase respect to the optimal working temperature of the selected oil.The maximum continuous working temperature is 70 °C, the tempera-ture must be measured from motor drain line. If the motor doesn’t have a drain line, the temperature must be evaluated at the return line port.

Filtration Hydraulic systems oil must always be filtered. The choice of filtration grade derives from needs of service life and money spent. In order to obtain stated service life it is important to follow our recommendations concerning filtration grade. When choosing the filter it is important to consider the amount of dirt particles that filter can absorb and still operate satisfactorily. For that rea-son we recommend filters showing when you need to substitute filtering cartridge. · 25 μm filtration required in most applications· 10 μm filtration in closed circuit applications

Oxidation Hydraulic oil oxidizes with time of use and temperature. Oxidation causes changes in colour and smell, acidity increase or sludge formation in the tank. Oxidation rate increases rapidly at surface temperatures above 60°C, in these situations oil should be checked more often. The oxidation process increases the acidity of the fluid; the acidity is stated in terms of the “neutralization number”. Oxidation is usually slow at the beginning and then it increases rapidly. A sharp increase (by a factor of 2 to 3) in neutralization number between inspections shows that oil has oxidized too much and should be replaced immediately.

Water content Oil contamination by water can be detected by sampling from the bottom of the tank. Most hydraulic oils repel the water, which then collects at the bottom of the tank. This water must be drained off at regular intervals. Certain types of transmission oils and engine oils emulsify the water; this can be detected by coatings on filter cartridges or a change in the colour of the oil. In such cases, obtain your oil supplier advice.

Degree of contamination Heavy contamination of the oil causes wear rising in hydraulic system components. Contamination causes must be immediately investigated and remedied.

Analysis It is recommended oil being analyzed every 6 months. The analysis should cover viscosity, oxidation, water content, additives and contamination. Most oil suppliers are equipped to analyze oil state and to recommend appropriate action. Oil must be immediately replaced if the analysis shows that it is exhausted.

Freewheeling In hydraulic special applications like for example drilling machines, mobile applications, cavitation may be present. Infact when the motor is forced to run at a certain speed that requires an oil flow that is not disposable from the pump, in a transitory or continuous situation, the oil pressure inside the motor pistons decrease and can cause many pro-blems like tractive forces on connecting rods retaining rings, metallic erosion (due to the air/vapor bubbles that develop when the piston pressure is very low and explodes when pressure rise above the equilibrium vapor pressure) and overheating.It’s always better to avoid motor cavitation or at least reduce it during operation (instal-ling for example proper valves and using well designed circuits) but when this event cannot be avoided HC series motors are a very good solution in order to guarantee the correct motor operation in a safe and efficient way. It’s always good to take into conside-ration circuit modifications in order to avoid cavitation mainly because the other com-ponents that are present in the circuit can be more sensible to the problem than the HC motor, therefore the HC can have an efficiency loss due not to the motor characteristics but to a bad cavitation resistance of the other circuit components.

Pressurization circuit

Please notice that using an auxiliary pump or a properly designed oil accumulator, in many cases (through the low pressure pipe pressurization) cavitation can be avoided or in all cases much reduced.

Low-speed freewheeling circuit

When the freewheeling requested speed is not high, the circuit shown on the left can be used. The speed for example can be controlled through a variable throttle valve. The main problem is that especially when throttle is acting, oil temperature can reach critical values.

High-speed freewheeling circuit

Realizing the freewheeling in this particu-lar way the motor operates without oil into the pistons, so the energy consumption is always the same and indipendent by the motor speed. In addition this energy loss is very low. This is the most suitable circuit for high speed freewheeling operation.

For more details on the above mentioned arguments and for any fur-ther information please contact our technical department.

FREEWHEELING OPERATION

IMPORTANT NOTE:For freewheeling opera-tion always select wheel

motors composed by HC motors.

TACHOMETERS - VALVES

Italgroup W series motors can be equipped with tachometers (different types are available, refer to the following pages for selection) and with hydraulic valves.

Regarding valves, if a group with HC motor is selected, the valve can be easily fitted direct-ly to the motor distributor D47. For this reason, when customer needs a valve fitted on the wheel motor, we highly recommend the selection of a W wheel motor realized with HC05, HC1 or HC2 hydraulic motor.

If the selected W assembly is realized with a G100 or GD100 motor, in case an hydraulic valve is needed, please contact Italgroup for more information.

In special cases, personalized valve blocks are available upon request, please contact us for more information.

Contact Italgroup technical department for further information/requests.
