Technical characteristics and review of the Kirovets K-700 tractor

The Soviet-era Kirovets K-700 tractor was used for plowing, loosening a wide variety of soil, sowing, etc. By the end of the 60s, it began to be used in road and transport construction, earthmoving, and reclamation work. Kirovets was produced at the Kirov machine-building plant in Leningrad for more than 10 years. K-700A and K-701 are improved Kirovets models, fundamentally different from their prototype, which began to appear only in the early 70s.

Scope of application of the K-702 tractor

So, “K-702” is an industrial modification of the heavy energy-rich “Kirovets” tractor, with the purpose of using it as a loader, bulldozer, roller, scraper. Compared to the classic “Kirovets”, the “K-702” has a modified linkage system, only a hydromechanical transmission is used, and the suspension is rigid.

In accordance with the recommendations of the customer (Ministry of Defense), the tractor is capable of effectively performing the following special energy-intensive work in a short time: moving soil; rapid formation of transitions and crossings through ditches and ravines, exits to crossings; laying column tracks in areas overgrown with small forests and shrubs, saturated with stones and boulders, on virgin snow; clear roads of snow and level them from damage; dig pits in soils of categories 1-3.

Naturally, the K-702 tractor also performs “less special” operations in industry and construction very successfully and in the shortest possible time. Among them are digging pits and loading bulk, lump materials into vehicles; development and movement of soil during construction, repair and maintenance of roads, at construction sites; forming embankments and graders, filling ditches and holes, clearing areas and roads after heavy snowfalls. All this is, in general, business as usual for Kirovets.

The Kirovets K-702 tractor, or universal road machine (UDM-2), combines the functions of a loader and a bulldozer. This is a powerful, productive and multifunctional road construction equipment. A universal industrial tractor with an articulated frame is equipped with a front-end single-bucket loader TO-34 (PK-6) and a single-cylinder bulldozer. Blade type - hemispherical, with transverse distortion. The presence of a torque converter (GTR) maintains a favorable operating mode of the gearbox and engine when the machine is operating in the most difficult conditions.

Repair and tuning of K-700 tractors

Parts of the K-700, like any tractor, fail or break down, and therefore require maintenance or major repairs.

Tractor repair consists of the following:

1. Valve adjustment is carried out for stable operation of the machine. The norm for thermal clearances of the valve mechanism is 0.25-0.30 mm. If the valve is incorrectly adjusted, this will affect the operation of the motor.
2. Repair of the K-700 gearbox is carried out by replacing faulty parts.
3. The relay is adjusted to maintain the voltage in the battery. It is important to correctly connect the electrical wires to the motor and pay attention to changes in the regulated voltage. For seasonal settings there is a Winter-Summer switch.

For Kirovets tractors, tuning was as follows:

• the tractor driver's cabin has been improved;
• the bumper and fenders were changed;
• tires were changed;
• engine replacement;
• modern hydraulic and pneumatic systems;
• replacement of electrical equipment and wiring.

For the K-700, tuning of the Kirovets tractor was carried out based on the needs and demand of consumers.

Tractor engine "K-702"

The K-702 tractor is equipped with a 4-stroke, 8-cylinder, V-shaped diesel engine YaMZ-238 ND3-1. This 14.87-liter engine is equipped with a turbocharging system and liquid cooling. Its rated power is 235 horsepower (or 173 kW). The nominal crankshaft rotation speed is 1,700 min-1. Specific fuel consumption at rated power is 218 g/kWh (160 g/hp/h). Pre-start heating of the engine is provided using the PZD-30 device. The fuel tank capacity is 320 liters.

The power unit, tested on a large number of special machines, has a number of undeniable advantages. In particular, he is loyal to diesel fuel that does not meet the modern level of quality. It also has excellent maintainability and, which is also important, does not have the slightest problem with spare parts.

YaMZ-238 diesel engines are used and very well known in absolutely all regions of Russia. To set up the fuel equipment, which is a classic in-line high-pressure fuel pump, ordinary mechanical stands are sufficient, and almost any service station will be able to sort out the fuel injection pump, replacing, if necessary, its individual sections.

Transmission, axles, steering and brake control "K-702"

The tractor is equipped with a manual transmission, also Yaroslavl, two-mode (working and transport modes), reversible, four-speed, with hydraulic gear shifting. The tractor transmission is equipped with a single-stage torque converter.

The number of gears in each mode is two forward and two reverse. The total number of gears is eight: four forward and four backward. Torque from the gearbox is transmitted to the sub-engine and cargo axles, which were developed in-house by the Leningrad enterprise.

All drive axles - both sub-engine and cargo - are equipped with differentials and planetary final drives. There is a differential and a self-locking freewheel. Thanks to this equipment, the tractor demonstrates high traction even on soft soils. Special tires with developed lugs also help to realize torque.

The Kirovets K-702 is equipped with 29.5/75R25 tires produced in Belarus (previously there were also deliveries from DneproShina, Ukraine). Tires designed for K-702 work in quarries differ significantly from the standard ones - they have a different tread pattern. There is also the possibility of additional tire protection with chains, which are offered as an additional option.

The cargo bridge has the ability to be turned off. This feature is very useful in a number of cases. In particular, when, for example, you need to transfer equipment from one object to another under your own power.

The steering of the loader is hydraulic, the steering column is adjustable. The service brakes are dry, shoe type with pneumatic drive. The parking brake is a shoe-disc brake with a pneumatic spring drive.

Tractor chassis and suspension; electrical equipment

The chassis of the “K-702” is wheeled, on pneumatic tires with a radial 22-layer tread. The wheels are single-pitch, discless. The suspension is balanced type on the sub-engine frame, and rigid on the portal frame.

The central hinge that connects the semi-frames deserves special mention. To be able to compensate for the wear of its parts, the designers provided a split pin, which is tightened as necessary during tractor maintenance. In addition, an additional external bushing is also introduced into the hinge - a kind of safety element that protects the “ears” of the frames in the event of large play in the hinge or when impact loads are applied to the metal.

The electric single-wire system of the K-702 tractor operates two 12-volt batteries with 190 ampere-hours each. The generator power is 2 kilowatts. The mains voltage is 24 Volts.

Front loader Kirovets K-702MA-PK6

The front-end single-bucket loader "Kirovets" K-702MA-PK6 is intended for use in loading and unloading operations with bulk and lump materials without preliminary loosening, for performing earthmoving and transport work on soils up to category III with unloading the material into a dump or vehicles. The loader can be used in construction, agriculture, land reclamation.

The use of jaw grips allows the loader to be used as a timber stacker for moving, stacking and performing loading and unloading operations at timber warehouses, logging, rafting and wood processing enterprises.

Specifications:

Cabin of the K-702 tractor

The K-702 tractor is distinguished by a spacious two-seater sealed cabin. The cabin is all-metal, with decent modern thermal, vibration and noise insulation, with a built-in safety cage that protects the operator in the event of a machine rollover (“ROPS”) and from falling objects (“FOPS”). The operator’s workplace is equipped with the ability to regulate the thermal conditions and powerful ventilation. There are two heaters, two fans for blowing the front and rear windows, the windows are tinted.

The cabin of the K-702 tractor is characterized by a convenient location of the main controls and a sprung seat. A special instrument panel with automated control of the operation of the loader systems helps reduce operator fatigue during the work shift.

A characteristic feature of the operator’s workplace of the K-702 tractor is the presence of a reversible control post: the operator’s seat, together with the steering column, rotates 180 degrees within a minute.

Parameters of tractor working equipment (bulldozer and loading)

Loading:

The geometric capacity of the bucket is three cubic meters; nominal – 3.5 m3. The rated load capacity of the bucket is six tons. The maximum unloading height of the bucket along the cutting edge, with an unloading angle of 45°, is at least 3.26 meters. The width of the cutting edge is 3.1 m. The breakout force developed by the bucket hydraulic cylinders is 22.630 tons.

The maximum height of unloading of the bucket along the cutting edge, with an unloading angle of 45 degrees, is 3.2 m. The reach of the cutting edge of the bucket at the maximum height and unloading angle and unloading angle of 45 degrees is 1.3 m. The maximum operating angles of the loading bucket are - 20 degrees of ascent (descent) and 12 degrees of roll.

Bulldozer:

Width x Height of the bulldozer blade is: in bulldozer position – 3.36 m; in grader position – 3.23 m. Maximum blade depth – 520 mm; maximum lift – 1300 mm. Average blade lifting speed at 1700 rpm. is 0.37 m/s. Average blade lowering speed at 1700 rpm. – 0.3 m/s.

The angle of installation of the blade in the grader (left and right) position is 26 degrees. The blade lateral tilt angle is 11 degrees.

When laying column tracks, the K-702 tractor demonstrates the following performance: on moderately rough terrain: 2 km/h; on virgin snow with a meter depth of snow cover: 0.5-1 km/h. When filling holes and ditches: 120 cubic meters per hour. When digging pits - 85 cubic meters per hour. When loading bulk materials - 100 m3 per hour.

The time for transferring working equipment (blade or bucket) from transport to working position, or vice versa, is 60 seconds.

Optional equipment

As additional equipment options for the K-702 tractor (by separate order), it is possible to install the following standard equipment:

• The buckets are enlarged, with a capacity of up to 4.35 cubic meters; on the contrary, reduced, with a capacity of up to 2.6 cubic meters. And also double-jawed, with a capacity of up to 3 cubic meters.
• Jaw grippers (with a load capacity of 6 tons)
• Cargo forks (with a lifting capacity of 6 tons)
• Beamless crane booms (load capacity 6 tons)
• Special career tires.

The tractor cabin, also as an additional option, can be equipped with air conditioning.

During each maintenance, all existing grease nipples installed in the hinges must be bypassed with a grease fitting. In order not to waste time on this, you can order an automatic, centralized lubrication system, which is also offered as an option. A set of imported Lincoln equipment will cost a round sum of about a thousand euros.

Another useful additional option is the fuel tank heating system. Diesel fuel is heated by pipelines with coolant circulating through them from the liquid preheater circuit.

For large operating organizations, a system for monitoring the location of the machine is provided. If you add fuel consumption sensors to it, you can successfully combat unauthorized fuel drains.

Reviews about the K-702 tractor

As one of the most important advantages, many owners of this equipment and machine operators working on it note the ease of its operation and maintenance. All necessary maintenance actions can be performed by the operator and do not require additional training. The maintenance interval is 250 operating hours. For the hydraulic system, the interval between maintenance is 1000 operating hours.

The hood lids open wide, providing very convenient access to the engine. High pressure hoses and units are available for maintenance, replacement and repair.

The powerful “stove” inside the tractor deserves all praise. The seat is comfortable and, together with the steering column, simply rotates 180 degrees.

The hydraulics are equipped with simple and effective protection against dirt and snow. The central hinges have a gap compensation mechanism. The driveshaft is located high - it is simply impossible to damage it. The disconnectable cargo (front axle) allows you to save the units.

The 702nd “Kirovets” is good in operation: it “rows” vigorously with all four wheels, and picks up a lot in the bucket. But it is not always possible to work with very rocky or viscous soils as successfully as with ordinary ones.

Those who have gained experience working on both the K-702 and its imported “classmates” and can compare, oh, it’s a rather clumsy machine. This is a minus. The cabin of the K-702, in comparison with the “foreigners”, with all due respect to the Kirovets, still represents the “last century”. The tractor works great for the first three years, but then periodic problems begin, primarily with the steering. However, the disadvantages are offset by the relatively inexpensive “cost of ownership” of the tractor, the cheapness and availability (in terms of availability) of consumables, spare parts and other components.
