Engine Specifications:
The SD22 Bulldozer is equipped with a Cummins NTA855-C280 BC 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 type 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 controlled, while the steering brake is wet, floating, and operates with direct on-off hydraulic inter-linking.

Undercarriage System:
The undercarriage features a swing type of sprayed beam with a suspended structure of an equalizer bar. It includes 2 carrier rollers and 6 track rollers per side, with track shoes assembled as single-tooth shoes (38 per side). The width of the track shoes is 560 mm, and the pitch is 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 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 bulldozer is equipped with different blade types: Straight-tilt, Angle, and Half U-Blade. The dozing capacities are 6.4 m³, 4.7 m³, and 7.5 m³ respectively. The blade widths are 3725 mm, 4365 mm, and 3800 mm, with heights of 1315 mm, 1055 mm, and 1343 mm. The maximum drop below ground is 540 mm, and the maximum tilt adjustment is greater than 735 mm, 500 mm, and 755 mm respectively. The weights of the blades are 3630 kg, 3850 kg, and 4196 kg.

Ripper Specifications:
The 3-Shank Ripper has a maximum digging depth of 666 mm and a lift above ground of 555 mm, weighing 2495 kg. The Single Ripper has a maximum digging depth of 695 mm and a lift above ground of 515 mm, weighing 2453 kg.

Additional Specifications:
The bulldozer has a minimum ground clearance of 405 mm, operating weights of 23,450 kg, 23,670 kg, and 24,600 kg for different blade types, and a ground pressure of 0.077 MPa and 0.072 MPa. The minimum turning radius is 3.3 m, and the gradeability is 30 degrees. The track gauge is 2000 mm.
