Engine Specifications:
The SD22F Bulldozer is equipped with a Cummins NT855-C280 BC III engine, which is an in-line, water-cooled, 4-cycle, overhead valve, direct injection, turbocharged diesel engine. It has a rated power of 162 kW (220 HP) at 1800 rpm, with a cylinder configuration of 6 cylinders, each with a bore and stroke of 139.7 mm x 152.4 mm. The piston displacement is 14,010 ml, and the minimum fuel consumption is 205 g/kW.h. The engine delivers a maximum torque of 1030 N.m at 1250 rpm.

Power Transmitting System:
The bulldozer features a 3-element, 1 stage, 1 phase torque converter. The transmission system is a planetary gear with a multi-disc clutch, hydraulically connected and forced lubrication. The main drive uses a spiral bevel gear with splash lubrication and single-stage speed reduction. The steering clutch is wet, multi-disc, spring-loaded, hydraulically separated, and controlled. The steering brake is wet, floating, and operates with direct on-off hydraulic inter-linking. The final drive is a 2-stage speed reduction of spur gear with splash lubrication.

Undercarriage System:
The undercarriage includes a swing type of sprayed beam with a suspended structure of an equalizer bar. Each side has 2 carrier rollers and 6 track rollers (4 single flange, 2 double flange). The track type consists of assembled single-tooth shoes, 38 on each side, with a width of 610 mm and a pitch of 216 mm.

Hydraulic System:
The hydraulic system operates at a maximum pressure of 14 MPa, using a gear pump with a discharge rate of 262 L/min at 1800 rpm. The working cylinder bore is 120 mm with two double-acting types.

Travel Speed:
The bulldozer has three forward gears with speeds ranging from 0-3.6 km/h, 0-6.5 km/h, and 0-11.2 km/h, and three reverse gears with speeds ranging from 0-4.3 km/h, 0-7.7 km/h, and 0-13.2 km/h.

Blade Specifications:
The blade is a straight-tilt type with a minimum ground clearance of 405 mm. The operating weight is 23,400 kg, and the ground pressure is 0.072 MPa. The minimum turning radius is 3.3 m, and the gradeability is 30 degrees. The track gauge is 2000 mm. The blade has a dozing capacity of 6.4 m³ and a theoretical efficiency of 330 m³/h over 40 m. The blade dimensions are 3725 mm in width and 1315 mm in height, with a maximum drop below ground of 540 mm and a tilt adjustment of over 735 mm. The blade weight is 2768 kg.

Overall Dimensions and Winch:
The overall dimensions of the bulldozer are 1683 mm in length, 1364 mm in width, and 1365 mm in height. The winch has a drawing force of 220 kN with a full drum and 350 kN with a bare drum, and a drawing speed of 15.9 m/min. The cable dimension is Ø428 x 7000 mm, and the winch weight is 3000 kg.
