Technical Data
BRAKES
Service
All hydraulic brake system control. Transmission mounted pressure
compensating pump provides hydraulic pressure for brakes and steering.
Independent circuits front and rear. Each circuit incorporates a nitrogen
accumulator which stores energy to provide consistent braking response.
Front Brake Circuit Pressure .........................................159 bar (2 300 lbf/in²)
Rear Brake Circuit Pressure ............................................. 52 bar (750 lbf/in²)
Accumulators:
Nitrogen Precharge Pressure ......................................... 55 bar (800 lbf/in²)
Front:
Type ............................................................ Dry Disc with 1 calliper per wheel
Disc Diameter ......................................................................965 mm (38 in)
Pad Area, Total ...............................................................2 015 cm² (320 in²)
Rear:
Type ..............................................................Oil cooled, multiple friction discs,
completely sealed from dirt and water.
Braking Surface, Total .............................................. 87 567 cm² (13 573 in²)
Parking
Application of rear brakes by springs in brake disc pack. Hydraulically released.
Hold-off Pressure ......................................................... 83 bar (1 200 lbf/in²)
Retardation
Modulated lever control of rear disc pack.
Retarder Actuation Pressure ...................................... up to 33 bar (480 lbf/in²)
Emergency
Push button solenoid control applies service and parking brakes. Automatically
applies when engine is switched off. Parking brake applies should system
pressure fall below a predetermined level.
Brakes conform to ISO 3450, SAE J1473.
STEERING SYSTEM
Independent hydrostatic steering with closed-centre steering valve,
accumulator and pressure compensating piston pump.
Accumulator provides uniform steering regardless of engine speed. In the event
of loss of engine power it provides steering of approximately two lock-to-lock
turns. A low pressure indicator light warns of system pressure below
83 bar (1 200 lbf/in²). Steering meets ISO 5010, SAE J53.
System Pressure ..........................................................159 bar (2 300 lbf/in²)
Relief Pressure ............................................................ 207 bar (3 000 lbf/in²)
Steering Cylinders ............................................. Double Acting, Single Stage
Accumulator:
Oil Capacity .......................................................... 16.4 litres (3.70 US gal)
Nitrogen Precharge Pressure .......................................... 55 bar (800 lbf/in²)
Steering Angle (Left and Right) ............................................................... 39°
