1.3 Tractor composition

Tractor framework – semi-frame.
Undercarriage: front and rear driving wheels, with pneumatic tyres of low pressure.
Steering wheels are front wheels. The wheels are twinned by means of spacers.
The tractor is equipped with 4-stroke piston six-cylinder inner combustion engine with
in-line vertical arrangement of cylinders, with direct injection of diesel fuel and compression
ignition, corresponding to environmental requirements of Stage 2.
System of engine lubrication is combined, some parts are lubricated under pres-
sure, some – by spattering. The lubrication system consists of an oil sump, oil pump, liq-
uid-oil heat exchanger, centrifugal oil filter and oil filter with paper filtering element.
The engine fuel supply system consists of a fuel pump, injectors, low-pressure
pipes, high-pressure pipelines, fuel coarse filter, fuel fine filter.
System of engine start-up is electric starter. A means of start-up facilitation under
low environmental temperatures is a heating plug.
System of air delivery consists of a turbocharger, air delivery pipeline and a system
of charged air cooling.
The turbocharger is executed as follows: radial centripetal turbine and centrifugal
single-stage compressor with cantilever arrangement of wheels in relation to supports.
The system of air purification consists of a dry-type air cleaner of "Donaldson" com-
pany FPG100318 with one paper filtering element P781039. This air cleaner has two stages
of purification.
Cooling system for charged air is of a radiator type. The CAC radiator is intended for
cooling the air, charged into the inlet collector.
System of engine cooling is closed-type with coolant compulsory circulation exe-
cuted by a centrifugal pump. The water pump is driven by a V-belt from the crankshaft pul-
ley. For acceleration of engine warming up after start-up and for automatic control of a
temperature mode at various loadings and ambient temperatures there are two thermo-
stats -107, mounted on the delivery line.
The coupling clutch is frictional, dry, two-disk, spring-loaded. The CC overlays are
ceramic-metal. The coupling control drive is hydrostatic with a hydraulic booster.
The gearbox is 24F + 12R, mechanical, fixed-ratio, with constant-mesh gears. Shift-
ing of 6 gears within each of four ranges of front motion and two ranges of reverse is exe-
cuted by means of synchro-mesh units, switching between ranges is executed by toothed
clutches and synchro-mesh units.
The rear axle:
- with the main drive as a pair of bevel gears with circular teeth;
- with a differential with a mechanical lock, with electrohydraulic control.
- with final drives as a pair of cylindrical gears;
- with hub drives of a planetary type;
