| HYDRAULIC SYSTEM | On the D-50 unit,
oil is supplied by a heavy-duty gear type two-section pump rated at 19 GPM(72 l/min) and
24 GPM(91 l/min) at 2500 RPM. Maximum operating pressure is 2000 PSI(13,800 k Pa). The
pump is gear driven from the engine accessory drive or from the front crank shaft. The hydraulic valves are stock sectional body directional control valves with an intregal non-adjustable relief valve. All controls are conveniently located on a single console for ease of operation. |
| AUGER ADAPTER | A heavy duty universal joint which mounts to the spindle with a single nut is provided for ease in hook-up and adjusting for misalignment. All components are sized to withstand torque and axial loads encountered under most drilling conditions. 1-5/8"(41.3 mm) female hex is standard, other sizes available. |
