If HFB, HFC and HFD or environmentally acceptablehydraulic fluids are being used, the limitations regardingtechnical data and seals mentioned in RE 90221 andRE 90223 must be observed.

The temperature inthe bearing area is - depending on pressure and speed - up to22 °F (12 K) higher than the average case drain temperature.Special measures are necessary at temperatures between-40°F and -13°F (-40°C and -25°C).

We recommend that the highest possible viscosityrange should be selected in each case.Example: At an ambient temperature of X°F (X°C) an operatingtemperature of 140°F (60°C) is set in the circuit. In theoptimum operating viscosity range (ν opt ; shaded area) thiscorresponds to the viscosity classes VG 46 or VG 68; to beselected: VG 68.Please note: The leakage fluid temperature, which is affectedby pressure and rotational speed, is always higher than the circuittemperature or tank temperature. At no point in the systemmay the temperature be higher than 240°F (115°C) for sizes 5to 200 or 195°F (90°C) for sizes 250 to 1000.If this cannot be achieved due to unusual operating parametersor high ambient temperatures, we recommend to apply bearingflushing at port U (sizes 250 ... 1000) or the use of a flushingand boost pressure valve (see page 30).FiltrationThe finer the filtration, the cleaner the fluid, the longer the servicelife of the axial piston unit.To ensure proper function of the axial piston unit, the Hydraulicfluid must have a cleanliness level of at least20/18/15 according to ISO 4406.At very high hydraulic fluid temperatures (90°C to max. 115°C, notpermitted for sizes 250 to 1000), a cleanliness level of at least19/17/14 according to ISO 4406 is required.Please contact us if these cleanliness leveles cannot be achieved.

The permitted loadingwith intermittent case drain pressure depends on the rotationalspeed (see chart). Short-term (t < 5 min) pressure spikes of upto 145 psi (10 bar) absolute are permitted.The average permanent case drain pressure must not exceed43.5 psi (3 bar) absolute.The pressure in the case must be equal to or greater than theexternal pressure on the shaft seal.Sizes 10...200barpsi101409perm. pressure pabs. max.

30/36 Bosch Rexroth Corp. AA2FM RA 91 001/07.05Flushing and Boost Pressure ValveThe flushing and boost pressure valve is used to remove heat.In the closed circuit additionally to the case flushing also theminimum boost pressure is assured.Hydraulic fluid is drained from the relevant low-pressure sideinto the motor housing. Along with the leakage fluid, it is thendischarged into the tank. The hydraulic fluid removed from thecircuit must be replaced in the closed circuit with hydraulicfluid by the charge pump.Opening pressure of charge pressure valve 230 psi / 16 bar(fixed setting). Must be taken into account when setting thecharge pressure on the pump in the closed circuit.On port plate 527, the valve is fitted directly onto the fixeddisplacement motor (size 45-180, 250), while on port plate 017(size 355 and 500), it is fitted on a plate.Orifice can be used to adjust the flow as required.Standard flow (at low pressure Δp = 365 psi / 25 bar)Size Flushing flow Orifice-No.45, 56, 63 0.93 gpm (3.5 L/min) R90965176680, 90 1.32 gpm (5 L/min) R909419695107, 125 2.11 gpm (8 L/min) R909419696160, 180 2.64 gpm (10 L/min) R909419697250 2.64 gpm (10 L/min) on request355, 500 4.23 gpm (16 L/min) on requestFor sizes 45...180, restrictors for flows of 3,5 - 10 L/min can besupplied.

AA2FM RA 91 001/07.05Counterbalance Valve BVDFunctionDriving/winch counterbalance valves prevent the motor fromover-speeding (i.e. -out of control) during overrunning load conditions,which causes motor cavitation in open circuit systems.This overrunning load-induced cavitation occurs in axial pistonmotors when the motor speed exceeds the speed that wouldbe reached with the available oil flow.Unit dimensionsB1B3TPlease request a certified installation drawingbefore finalizing your design.Dimensions in inches and (millimeters)Pressure relief valves,see page 31Please note– BVD counterbalance valve must be specified explicitly in theorder.

Do not remove the tacking boltswhen attaching the working lines. If the counterbalance valveand motor are delivered separately, the counterbalance valvemust first be fastened to the motor port plate using the tackingbolts provided. In both cases, the final fastening of the counterbalancevalve to the motor is done using the threaded connectionof the working lines, e.g. using SAE flanges. A total of 6bolts with thread lengths B1+B2+B3 and 2 bolts with threadlengths B3+B4 will be required.When tightening the bolts, it is vital that the sequence (1 to 8)as shown in the diagram is adhered to and carried out in twophases.In the first phase the bolts should be tightened to 50% of theirtightening torque before being tightened to maximum tighteningtorque in a second phase (see table below).Thread 1 ) Property class Tightening torqueM10x1.5 10.9 55 lb-ft (75 Nm)M12x1.75 10.9 95 lb-ft (130 Nm)M14x2 10.9 150 lb-ft (205 Nm)1 ) fastening screws according to DIN 912Detail YPlease request a certified installation drawingbefore finalizing your design.Dimensions in inches and (millimeters)2673Y4851Flange, e.g.SAE-flangeTacking bolts(M6x1, DIN 912)Size 28, 32, 45 56, 63 80, 90Dim.

RA 91 001/07.05 AA2FM Bosch Rexroth Corp. 35/36Installation and Commissioning NotesGeneralThe motor case must be completely filled up with hydraulic fluid during startup and during operation (filling the case chamber). Themotor must be started at low speed and no load until the system has been bled completely.If stopped for an extended period, fluid may drain out of the case through the working lines. When restarting, make sure that thecase contains sufficient fluid.The leakage fluid inside the case chamber must be drained off to the tank through the highest case drain port.Installation positionOptional. At size 10 ... 200 with installation position “shaft to the top” use motor with bleeding port R (indicate in clear when ordering;the port U in the bearing section for bleeding is included in production with sizes 250 ... 1000).Installation below tank levelMotors below minimum fluid level in the tank (standard)– Fill axial piston motor before startup via the highestcase drain port– Run the motor at low speed until the system is bledcompletely (bleed through service line port A, B if tubing islong)– Minimum immersion depth of leakage line in tank:7.87 in /200 mm (relative to the min. fluid level in the tank)– Additional measures required for installation position 2(shaft facing up): with installation position 2, make sure thatthe motor case is completely full before starting up. Bleed atport R (sizes 10...200) resp. U (sizes 250...1000). Order portR in clear text. An air pocket in the bearing area can causedamage to the motor.Installation above the tankMotor above minimum fluid level in tank– Proceed in same way as below the tank installation– Additional measures for installation positions 1 and 2:If stopped for an extended period, fluid may drain out of thecase chamber through the service lines (air enters throughthe shaft seal). The bearings will therefore not be properlylubricated when the motor is started up again. Fill the axialpiston motor before restarting via the highest case drain port.Installation position 2: bleed at port R (sizes 10...200)resp. U (sizes 250...1000). Order port R in clear text.– Additional measures required for installation position 2(shaft facing up)In this installation position the bearings will not be properlylubricated, even if there is still some fluid in the case chamber.Putting a non-return valve (opening pressure 7.25 psi/0.5 bar) in the leakage line can prevent the system emptyingthrough the line.T 1T 2Installation position 1T 1T 2Installation position 2T 1R(U)T 2Installation position 27.25 psi (0.5 bar)T 1T 2R(U)
