[4] CHARGE PUMP
The charge pump is necessary to make up for leakage from the pump and motor, preventing cavitation.
This charge pump always revolves in combination with the pump shaft to draw oil from the transmission case, and
feeds oil to the implement lifting circuit and charge circuit.
[Charge Pump Displacement]
As for charge circuit of the charge pump, refer to Workshop Manual for G1700 ·
G1800 · G1900 · G2000 (code No.
9Y021-10834).
