vehicles are equipped with a dual vane pump. Both sections of the dual
vane pump are activated by two electric solenoid valves (except when a hot-shift PTO is used). One is
mounted on the arm vane pump at the front of the truck, the other on the bottom center of the body
near the main valve (see Figure 5
2). The electric signal that activates the solenoid is sent by the
pump switch on the in-cab control panel.

When the dual vane pump is turned on, the transmission electronic control unit (
ECU
) starts
monitoring vehicle and engine speed, and allows the vane pump to engage (or not). If the vehicle is
going faster than 15 mph (25 km/h) or if the engine speed exceeds 900 rpm, the vane pump will not
engage.
The first section of the vane pump, known as the
body vane pump, located closer to the pump shaft,
powers all body functions (tailgate and packer) through the directional control valve (see next
section). It is capable of delivering a flow of 24.5 gallons per minute (gpm) at 700 rpm. A dump valve
located on the bottom center of the body near the main valve (see Figure 5
2) limits the flow to the
valve to 60 gpm. All excess flow is sent back to the hydraulic tank. When the pump is turned off, the
oil returns to the hydraulic tank.

When a hot-shift PTO is engaged, the pump stops rotating.
The second section of the vane pump, known as the
arm vane pump, powers lifting arm functions and
other options through the proportional valve (see
Proportional Valve on page 110). It is capable of
delivering a flow of 16 gpm at 700 rpm. A dump valve located at the pump outlet limits the flow
2) to the valve to 20 gpm. All excess flow is sent back directly to the pump inlet. When
the pump is turned off, all the oil returns to the inlet.
