SECTION II. EQUIPMENT DESCRIPTION AND DATA

TM 5-2590-512-13&P 1-5. Preparation for Storage or Shipment. Refer to Chapter 4, Section IV, for procedures for preparing Earth Auger Assembly for storage or shipment. SECTION II. EQUIPMENT DESCRIPTION AND DATA. 1-6. Equipment Characteristics, Capabilities, and Features. Description. Earth Auger Assembly is attached to and controlled from SEE vehicle. SEE hydraulic pump delivers fluid under pressure, thru hoses, to hydraulic motor in Auger Drive Unit. This provides rotational movement to Auger. Four adjacent teeth (two per side), (10), mounted on cutting head (11), dig hole, as SEE operator lowers boom/dipper and attached Auger into ground. Boom will not obstruct line of vision of Earth Auger Assembly operator if hole site is at either 10 to 11 o'clock or 1 to 2 o'clock position. Characteristics. Earth Auger Assembly is designed to be attached to rear of Small Emplacement Excavator (SEE) and is operated and powered from it. Metric sizes are not used and no special tools are required. Capabilities and Features. SEE vehicle rear bucket is removed and Auger Drive Unit is installed in its place. Earth Auger Assembly can dig 12" holes in natural earth soil, to depth of approximately 72" or 6 feet. Short Distance Moving. Earth Auger Assembly may be left attached to SEE vehicle, but it must be tied down or monitored to minimize swinging. Long Distance Moving. There is no room or provision on SEE vehicle to secure Auger when moving it long distances. Disconnect Auger from Auger Drive Unit and transport it in a companion vehicle. 1-7. Location and Description of Major Components. a. Earth Auger Assembly has two major components-Auger Drive Unit (1) and Auger (2). b. Auger Drive Unit (1) uses connecting link (3) to interface with SEE dipper. Inside of Auger Drive Unit (1) is hydraulic drive motor, drive chain, sprockets, bearings, and a solid hex shape output shaft. Two 138" hoses (4) are connected thru two quick disconnect fittings into top of Auger Drive Unit. 1. Auger Drive Unit connecting link (3) is a universal type drive coupling and provides constant multi-direction Auger movement during hole digging. 2. Auger shaft (5) is hollow and also hex shape. It slides over solid shaft (6) of Auger Drive Unit. 3. When Auger shaft (5) and Auger Drive Unit shaft (6) are nestled, pin (7) is inserted into aligned holes. Hitch Pin Clip (8) is inserted into pin (7) end hole, (with hitch pin clip loop facing up), to secure parts together. 4. Front and rear metal covers (9) are safety covers. Greased rotating parts are kept inside Auger Drive Unit (1) and dirt and contaminants kept out. 5. A spare chain master link is stored on flat washer welded to motor plate inside Auger Drive Unit (1). c. Auger (2) is spiral shape. Four carbide tipped cutting teeth (10) are bolted to cutting head (11). Center point (12) guides Auger into center of selected hole. 1-2
