1. Running design.
2. Motor.
3. Cabin for tractor control.
4. Transmission.

Main details of the T-170 bulldozer

The general design of the unit is simple, which ensures its reliability. Each structural element is made of high-quality steel, providing the mechanism with a long service life.

Chassis

The bulldozer chassis is a welded structure equipped with crawler tracks suspended semi-rigidly at three points. Additionally, the frame is equipped with a balancing beam. The caterpillar carts are made of rectangular pipes, to which tension wheels supporting support rollers are attached.

The process of maneuvering the bulldozer and its braking is ensured thanks to the belt clutch. When one trolley is blocked, the direction of movement changes. Changing the locking force from partial to full allows you to influence the maneuverability of the turn, even moving in place.

Engine

The power unit is fixed in the front part of the running frame. It is a four-stroke diesel engine equipped with a liquid cooling system. It is started by an electric starter or an auxiliary carburetor engine.

Modifications of the bulldozer produced for operation in the north are equipped with a pre-start heating system.

Driver's seat

The tractor driver’s working area is not very comfortable, but much is provided for the driver’s convenience. The frame cabin is mounted on a platform and has vibration protection. Panoramic glazing guarantees good all-round visibility.

The driver's seat can change its position. An oil cooler provides interior heating. The dashboard has indicators that notify you of changes in the following parameters:

• remaining fuel;
• oil pressure;
• crankshaft revolutions;
• hydraulic condition;
• air purifier operation.

All levers are located conveniently, they ensure comfortable movement. The lever system controls the maneuvering of the bulldozer. To change the direction of movement, it is enough to partially block one of the crawler tracks. The more you brake, the smaller the turning radius will be.

Hydraulics

The unit is equipped with divided pump-type hydraulics. The pumps are gear-type, their separate operation is ensured by the presence of separate units for each element of the system. To clean the liquid in the circuit, a filter is provided.

The hydraulic pump is mounted directly on the engine. Various modifications of bulldozers were equipped with their own hydraulic pump configurations.

Electrics

The tractor is powered by two batteries supplying 24 V and a generator. They provide:

1. Starting the unit.
2. Lighting.
3. Instrumentation power supply.
4. Sound and light alarm.
5. Heating.

Transmission

The basic assembly of the tractor provides for 13 speeds, of which 9 are forward. Various modifications of the unit have a hydromechanical or mechanical transmission - it all depends on the purpose of the bulldozer.

With a hydromechanical design, the gearbox has 6 speeds for moving forward and 3 in reverse. The design allows you to change gears without slowing down.

Additional accessories

Additional accessories are tools that guarantee the functionality of the bulldozer in a certain area of ​​application. Most often this equipment is presented:

• ripper fangs;
• front blades of all kinds;
• grips that allow laying pipes of small diameter;
• devices designed for uprooting stumps in the area.

Peelers and plows are used as attachments for agricultural machinery.

Attachments

The following mechanisms are often used as auxiliary equipment:

• dumps;
• traction winches;
• rippers;
• pipelayers;
• stump removers.

Bulldozers with a straight fixed blade perform leveling work, prepare construction sites, and fill trenches and pits. The main application of straight rotary devices is road construction, cleaning road surfaces from soil deposits.

A fixed blade with hydraulic distortion is used when changing position in the vertical plane. While working on slopes, the bulldozer maintains straight-line movement.

The hemispherical blade is characterized by versatility and high efficiency. To increase the volume of soil moved, the mechanism is equipped with side cheeks and a visor.

A spherical fixed blade is used to move crushed stone, slag, and coal. Rounded side sections help move soil toward the center of the dump, which reduces material loss during transportation and increases its volume.

Rooters are installed instead of a classic blade and are intended for removing stumps, bushes, small trees, and stones when clearing clearings.

To remove the top soil layer, reclamation dumps with wide sections are used.

Coal and peat attachments are designed specifically for working with bulk materials.

Main modifications

More than 80 modifications of the bulldozer are offered on the market. Each modification is assigned a symbol that differs in technological characteristics:

• by cabin design and engine type;
• by modification;
• by type of starting device;
• by type of bulldozer or ripper equipment;
• by the appearance of the rear linkage.

Bulldozers are widely used in construction and agriculture:

• T-170.01 with electric starting system;
• swamp vehicle T-170B.01-1 with electric starter;
• T-170MB.01-1DZ - swamp vehicle with a 4-sided cabin, D-180 engine, electric starter and direct rotary blade.

Repair of bulldozer T-170

Repair of the T-170 tractor can be either routine or major. Routine maintenance involves replacing wearing parts. When overhauling a T-170, complex work of any level of complexity is carried out.

The need for technical procedures is indicated by the limiting state and malfunctions of assembly units. Before starting the process, the machine is diagnosed.

If there are defects in the engine, the piston group and liners are changed, the valves are adjusted, the oil pump is repaired, and the fuel equipment is checked.

During the operation of the tractor, wear of the friction linings often occurs, as a result of which the clearance in the clutch and the free movement of the servomechanism rod decrease. With a gap of 2 mm and a free stroke of 6 mm, the T-170 clutch is adjusted.

If the side clutches slip, the steering control mechanism is repaired. The free play of the lever is set so that it corresponds to 55-80 mm to the right and left of the vertical position. Adjusting the clutches contributes to the correct operation of the mechanism.

Signs for repair of the chassis of the machine are wear, cracks, destruction of more than 50% of the road wheels, bearing seats, flanges, drive and tension wheels.

Caterpillars are expensive spare parts, so when operating a bulldozer, timely maintenance and repairs are carried out.
