RIGHT SIDE ORDERING CODE DX TRAVEL DIRECTION LEFT SIDE ORDERING CODE SX 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...

HYDRAULIC MOTOR INSTRUCTIONS AND ADVICES 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 application. 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...

HYDRAULIC MOTOR INSTRUCTIONS AND ADVICES Minimum speed 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 continuous motor case pressure must be maximum 6 bar). Flushing...

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 attention, 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...

HYDRAULIC MOTOR FLUID RECOMMENDATIONS 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 reason we recommend filters showing when you need to substitute filtering cartridge. · 25 μm filtration required in most applications · 10 μm filtration in closed...
