(1) Steering accumulatorSteering accumulator (1) provides the supply oil during normal operation. The accumulator also provides the oil for temporary steering if a loss of pump oil flow occurs.Steering accumulator (1) is located on the right side of the machine behind the front wheel. A rubber bladder is located inside the accumulator. The rubber bladder is charged with dry nitrogen. The nitrogen charge provides energy for normal steering and for secondary steering capability if steering pump flow stops.The oil pressure in the accumulator maintains the oil in the steering metering pump for quick steering response. The oil pressure prevents hard spots in steering by providing a steady flow of supply oil to the steering metering pump.
