The winch charge pump (Figure 15, Item 2) is a gear pump. The oil for winch charge pump first passes through the
charge filter (Figure 15, Item 23). The crossover relief valve and makeup valve (Figure 15, Item 22) allow charge oil
to enter the closed loop circuit. The charge oil accommodates internal leakage in the pump and the motor.
The winch pump solenoid valve (Figure 15, Item 19) will shift to the right or the left when the operator moves the
winch control to the REEL OUT or REEL IN position. The swashplate in the winch pump (Figure 15, Item 5) can
then move overcenter. The swashplate will move in the requested direction, and the pump will produce flow in the
appropriate side of the closed loop circuit for the winch. The flow of oil will cause the winch motor to turn.
