Location of the Accumulator for the Power Train

The accumulator for the power train is located on the bottom of the fuel tank at the back of the machine.

The accumulator stores potential energy by accumulating a quantity of pressurized power train oil. The pressurized oil is stored in an accumulator cylinder. The accumulator is charged to 1725 kPa (250 psi) with dry nitrogen.

The pressurized power train oil enters the accumulator and the oil creates pressure within the accumulator. Energy is stored as the cylinder that is within the accumulator is compressed by the power train oil. The accumulator supplements power train oil flow in low flow conditions.
