High-flow Machines
Oil is drawn from tank T by gear pumps P3, P4 and P5 via
suction strainer S. Loader pump P3 delivers pressurised
oil to loader control valve 9. The oil flow passes through
loader control valve 9 and joins the flow from high-flow
gear pump P5, passing through high-flow control valve 19
which feeds the attachment service. Oil returns to tank T
from control valve 9 via filter F2 and cooler C.
Charge pump P4 which is engine driven, delivers
pressurised oil to loader and transmission servo joysticks
and provides charge pressure to main pumps P1 and P2
via filter F1.
