A4VG085HW8D00T0/40ALNC6V81BB2S4AD00-YR902232839

Axial piston pump Bosch Rexroth series A4VG, type code A4VG085HW8D00T0/40ALNC6V81BB2S4AD00-Y, material number R902232839. Nominal size: NG 85. Axial piston unit: swashplate design, variable, nominal pressure 450 bar, maximum pressure 500 bar (A4V). Operating mode: pump, closed circuit (G). Control device: proportional control, hydraulic mechanical servo, hexagon shaft with lever with neutral position switch (HW8). Pressure cut-off: pressure cut-off, with bypass Fixed setting, hydraulic, mechanical (D). Connector for solenoids: without connector (only for purely hydraulic control) (0). Swivel angle sensor: without swivel angle sensor (0). Additional function: stroking chamber pressure port X X (T). DA control valve (only for NG110 and 125): without DA control valve (0). Direction of rotation: viewed on drive shaft counter-clockwise (L). Sealing material: NBR (nitrile rubber), shaft seal in FKM (fluoroelastomer) (N). Mounting flange: SAE J744 127-2/ (C6). Drive shaft: splined shaft 1 3/8 in 21T 16/32DP ANSI B92.1a–1976 (V8). Working port: SAE working port A and B, on left side (45° left) (1). Boost pump and rotary group configuration: standard rotary group boost pump integrated, large internal gear pump (B).
