NOTE: If vehicle is equipped with High Flow Hydraulics
Kit, refer to High Flow Hydraulics Kit Gear Pump Service
later in this section.
NOTE: The Workman HDX and HDX--D gear pump in-
cludes a rear flange that will allow the installation of a
second pump section for the High Flow Hydraulics Kit.
The Workman HD gear pump does not have this type of
rear flange. Figure 28 illustrates both pumps.
