(1) Outlet. (3) Cartridge Assembly. (4) Coupling.The implement pump is a vane pump which supplies the high pressure oil in order to operate the blade and any attachments in the implement system. Cartridge assembly (3) consists of a cam ring, vanes, and inserts, which rotate in order to provide pressure oil to the hydraulic system. Spline coupling (4) is used to drive the fan pump.

Implement Vane Pump Cartridge Assembly (AA) Supply oil. (BB) Pressure oil. (1) Cam ring. (2) Rotor. (3) Outlet. (4) Vane. (5) Inlet. (6) Slot. (7) Passage. (8) Inlet. (9) Insert. (10) Outlet. (A-F) Different vane positions.The following components are the components of the implement vane cartridges: inlet support plates, outlet support plates, seal packs, flex plates, cam ring (1), rotor (2), vanes (4) and inserts (9) .Note: For additional information on vane pumps, refer to Special Instructions, SMHS7047.Grooves in the flex plates allow pressure oil to flow to slots (6) in rotor (2). Oil from the slots then flows into the area between inserts (9) and vanes (4). The vanes are pushed out against cam ring (1) .As rotor (2) turns, the vanes in positions (E) and (F) move out. The vanes then follow the shape of the cam ring. As the chamber area between the vanes increases, a low pressure or a low vacuum is created in the chamber. This pressure difference causes oil to flow from the hydraulic tank through inlet (8). The oil fills the space between vanes at positions (E) and (D). The oil continues to fill the space through positions (D) and (A) .Oil between the vanes at positions (D) and (A) will be trapped when the vane at position (D) passes the end of inlet (8). As rotor (2) continues to turn, the vanes are pushed in by the contour of cam ring (1). The chamber area between the vanes now decreases. Oil between the vanes at positions (A) and (B) is pushed into outlet (3). The oil continues to be pushed out through positions (B) and (C). When the vane at position (B) passes the end of outlet (3), the cycle is completed.Both ends of the vanes are connected by passages (7) in the rotor. The oil in these passages will keep the pressure even on both ends of the vanes. This oil also permits the oil behind the vanes to escape as the vanes are pushed in.
