with Timken roller bearings, but friction bear- ings can be used on a locomotive of this type if desired. The pedestal ways of the truck frame and boxes are lined with manganese steel and provided with oil pockets to lubricate the wearing faces. An outstanding feature of the truck design is the provision for dropping a set of wheels without removing the traction motor from the axle. The illustration on page 6 shows a truck with a pair of wheels, complete with axle and motor, removed for inspection or repairs. In practice, this operation would ordinarily be done over a pit. The weatherproof engine hood is of steel plate, having removable top with sliding hatches and removable hinged doors alongside the engine and generator, giving access to parts requiring attention and possible replacement. The entire roof and sides of the hood can be removed if desired. The front section houses the radiators, cooling fan and motor, traction motor blower and the compressor compartment. The radiators are mounted vertically in the sides of the hood to prevent blanketing and insure a free circulation of air even though the front of the locomotive may be close against a box car or other high piece of equipment. The radiators have a capacity of 248 gallons of water, and sufficient additional capacity to cool the engine lubricating oil. Radiator fan speed can be controlled by the operator who thus ad- justs cooling-water temperature to suit outside weather conditions. Fuel is pumped from the tank in the main underframe by a geared pump driven by a 1/4 h.p. motor, to filters mounted in the hood. After going through the filters, the oil passes into an auxiliary tank under the top of the hood. This tank holds 12 gallons and its pur- |
pose is to insure a supply of fuel for several hours operation in case of an accident to the fuel pump. Fuel is fed by gravity from the auxiliary tank to the engine pump, thence to the Bosch fuel pump and sprayed into the com- bustion chamber. An emergency hand pump is placed in the fuel oil line between the main reservoir and the strainer, to be used in the rare event that the motor driven pump fails. An emergency fuel cut-off valve is installed on the locomotive and can be actuated by either one of two han- dles, one located in the cab and the other on the outside of the frame. The steel cab is entirely lined and floored with cork. Doors are of pressed steel and win- dow frames are of extruded aluminum. The entire locomotive, including engine, generator, traction motor, auxiliaries, lights and various accessories, is controlled from the cab. The compact, convenient control stand is on the right hand side. The operator not only has clear vision directly in front of him on the right hand side, but clear vision is also provided forward along the left-hand side by a suitable mirror. The hood is only 66 inches wide which gives excellent visibility. All doors and win- dows are weather-stripped and an automatic hot water heater provides comfort in winter. Windshield wipers and awnings are regular equipment. The accessories used on locomotive 62000 include the following: Miner A-22XB friction draft gear; type "E" A.A.R. swivel shank top operating couplers; bell with internal quick- acting bell ringer; Pneuphonic horn; Sunbeam 12-inch round case headlights, built into cab and hood respectively; King top operated sand- ers; and jacks, car replacers, inspection lights and other necessary tools. |
