Hydraulic Equipment 3. Lift the hydrostatic pump with an appropriate lifting device. NOTE: The hydrostatic pump weighs approximately 90-113 kg (200-250 lbs.).
NOTE: The gear pump for machines with the high-flow auxiliary option is shown in Fig. 502. Gear pump for standard flow auxiliary hydraulics is shown in Fig. 503.
4. Carefully lift hydrostatic pump (R, Fig. 501) into place using an appropriate lifting device. Align the splines on the pump input shaft with the adapter, and install the pump assembly on the adapter.
