Engine Specifications:
The SD22C Bulldozer is equipped with a Cummins NT855-C280 BCIII 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. The engine features six cylinders with a bore and stroke of 139.7 mm x 152.4 mm, and a piston displacement of 14,010 ml. The minimum fuel consumption is 205 g/kW.h, and the maximum torque is 1030 N.m at 1250 rpm.

Power Transmitting System:
The bulldozer uses a 3-element, 1-stage, 1-phase torque converter. The transmission is a planetary gear system with a multi-disc clutch, hydraulically connected and forced lubrication. The main drive consists of a spiral bevel gear with splash lubrication and single-stage speed reduction. The steering clutch is wet, multi-disc, spring-loaded, and hydraulically separated with hydraulic control. 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 features a swing type of sprayed beam with a suspended structure of an equalizer bar. Each side has carrier rollers and six track rollers (four single flange and two double flange). The track type is assembled single-tooth shoes with 38 per side, a width of 660 mm, and a pitch of 216 mm.

Hydraulic System:
The hydraulic system operates at a maximum pressure of 14 MPa with a gear pump type. The discharge rate is 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 of 0-3.6 km/h, 0-6.5 km/h, and 0-11.2 km/h, and three reverse gears with speeds of 0-4.3 km/h, 0-7.7 km/h, and 0-13.2 km/h.

Blade Specifications:
The blade type is a coal-blade with a minimum ground clearance of 405 mm and an operating weight of 24,600 kg. The ground pressure is 0.078 MPa, with a minimum turning radius of 3.3 m and a gradeability of 30 degrees. The track gauge is 2000 mm. The blade has a dozing capacity of 9 m³ and a theoretical efficiency of 450 m³/h over 40 m. The blade width is 4200 mm, height is 1350 mm, with a maximum drop below ground of 540 mm and a maximum tilt adjustment of over 755 mm. The blade weight is 3464 kg.

Overall Dimensions:
The maximum digging depth of the 3-shank ripper is 666 mm, with a maximum lift above ground of 555 mm and a weight of 2900 kg. The single ripper has a maximum digging depth of 695 mm, a maximum lift above ground of 515 mm, and a weight of 2453 kg.
