Workman HD Series Page 9 -- 41 Hydraulic System
The gear pump assembly used on Workman HDX and
HDX--D vehicle equipped with the High Flow Hydraulics
Kit is s hown in Figure 31. When servicing this gear
pump, follow the procedure for Gear Pump Service in
this section and the following:
1. Use Figure 31 as a guide when servicing pump.
2. Do not mix components from one pump section to the
other.
3. The High Flow Kit gear pump supplies oil flow for two
circuits and uses two separate reservoirs and oil types
(Fig. 32). The front pump section (closest to pump input
shaft) uses oil from the transaxle (Dexron III ATF). The
rear pump section uses oil from the High Flow Hydrau-
lics Kit reservoir (hydraulic oil). During gear pump as-
sembly, lubricate front section c omponents w ith clean
Dexron III ATF and rear section components with clean
hydraulic oil.
