(A) Outlet (high pressure)
(B) Inlet (low pressure)
(1) Pilot/brake pump Pilot/brake pump (1) is a fixed displacement external gear pump. The pump supplies flow to the hydraulic brake system and pilot flow for the implement system. When the pump is viewed from the drive end, the pump shaft rotates in a counterclockwise direction.Pilot/brake pump (1) is mounted on the fan pump on the left hand pump drive. The pumps are located behind the cab under the floorplate.

Fixed Displacement External Gear Pump
(2) Drive gear
(3) Idler gear
(A) Outlet (High pressure)
(B) Inlet (Low pressure) A gear pump carries oil from inlet port (B) to outlet port (A) in the spaces between the gear teeth.The drive shaft turns drive gear (2). The drive gear forces idler gear (3) to rotate. When the gear teeth separate, a partial vacuum is formed. Oil fills the spaces between the teeth in inlet port (B). The gears carry oil around the circumference of the pump to outlet port (A). A seal is formed by the gear teeth against the pump housing. Oil is forced out of the spaces between the gear teeth as the gear teeth mesh together at outlet port (A). Oil will not return to inlet port (B) because the meshing of the gears will fill the spaces between the gear teeth.The flow rate of oil that is supplied by the pump is controlled by the rate of rotation of the shaft.
