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 engine speed exceeds 900
rpm, the vane pump will not
engage. After the pump is engaged, it will stay engaged at any engine speed under 2300
rpm

Allison Transmission Parameters
The first section of the vane pump, known as the
body
vane pump, located closer to the pump shaft,
powers all body functions (tailgate, body hoist, and packer) through the directional control valve (see
below). It is capable of delivering a flow of 20
gallons per minute (gpm) at 700
rpm. A dump valve
located on the chassis (see Figure 5-1) limits the flow to the valve to 45
gpm. All excess flow is sent
back to the hydraulic tank. When the pump is turned off, the oil returns to the hydraulic tank.
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
on page 121). It is capable of
delivering a flow of 16
gpm at 700
rpm. A dump valve located at the pump outlet limits the flow
(see Figure 5-1) 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.
