UNDERCARRIAGE

Suspension: A three-point semi-rigid suspension with displaced oscillating axle of bogies provides higher traction characteristics, reduction of impact loads on undercarriage, improvement of working conditions.
Track rollers, support rollers and idlers feature a life-time lubrication and self-adjusting “duo-cone” seal packages.

Number of track rollers (each side) —6.
Number of support rollers (each side) —2.

Track chains: Assembled with single-grouser track shoes and a seal package for retaining a fluid lubricant in the hinge. The track chain tension can be easily adjusted with a grease gun.
Linkpitch —203mm
Number of shoes (each side) —39
Grouser height —65 mm
Shoe width —510 mm.
Base —2,616 mm
Ground contact area —2,668 m²
Ground pressure —0.75 kgf/cm²

GEARBOX

A planetary-type gearbox with oil operating, high capacity torque transmitting clutches 345 mm in diameter provides three forward gears and three reverse ones with gear shifting under load. Gear shifting is electrohydraulic. As per design the gearbox is connected with matching reducing gear and main drive forming a single power unit mounted on rear axle bore. A three-element one-stage torque converter with efficient diameter of 390 mm, maximum transformation ratio Ко = 2.539 with pumps drive reduction gear is connected with the gearbox by spline coupling and mounted on the front wall of the rear axle. Torque converter is connected with the engine through drive line and engine mounted elastic clutch mounted.

Gear	Forward, km/h	Reverse km/h
1	3,7	5,0
2	6,9	9,0
3	11,0	14,4

FINAL DRIVE

Final drive is of two-stages, the 1-st one having external gearing pinions and the second one of planetary "k+1" type (with the stopped crown gear). The sprocket has a 5-segment design, with the segments being bolt-on for easy replacement in field conditions.

HYDRAULIC SYSTEM

Remote-cylinder hydraulic system:

Sh100 gear pump of 163 L/min capacity at 1,800 rpm engine speed
Four-section control valve made by Bosch Rexroth company consistin of one valve section and three spool sections
Maximum relief valve setting —20 MPa (200 kgf/cm2)
Hydraulic tank capacity (welded tank suitable for mechanical treatment of inner surfaces) —85L

Spool sections	Positions of control valve spools	Number of cylinders	Cylinder bore, mm
Blade lift	Raise, neutral (hold), lower, float	2	100
Blade tilt	Right, neutral, left	1	140
Ripper lift	Raise, neutral, lower	2	100

RIPPER EQUIPMENT

Depending on the ripper working conditions, one, two or three shanks may be mounted which will provide high productivity.

Ripper type	Number of shanks	Weight, kg	lift above ground, max, mm	Digging depth, max, mm	Breakout force, max, T	Penetration force, max, T
Non-adjustable, multi-shank	1	1000	540*	640*	16,0	5.7
Non-adjustable, muni-shank	3	1285	500*	530*	17,158	6,14

DOZER EQUIPMENT

Large capacity of SU-blade provides increased productivity. The blade design ensures its effective application both for soil transportation and when trenching, performing leveling operations and road laying.

Blade	Blade length x height, В x H, mm x mm	Blade capacity, m²	Lifting over the ground,	Blade deepening, mm	Tilt adjustment, max, degrees	Weight, kg
SU-blade	3320×1625	5,6	1100*	550*	±9*	2280

* — with grouses deepened

WEIGHT

Tractor — 17300 kg.
Total weight (standard equipment, full fuel tank, SU-blade, three-shank ripper, operator) — 20 000 kg
