Tractor LTZ-60, 60A, 60AB, 60AV: characteristics, design, engines

General information

The SMD motor line includes the following motors:

• four-cylinder in-line;
• six-cylinder in-line;
• units with six cylinders are V-shaped.

It is also important to note that any of these motors are highly reliable. This parameter is ensured due to correctly adopted design decisions, which, even by today’s standards, may well ensure a long service life of this motor. To date, the production of this type of units has been established at the Belgorod Motor Plant.

Main modifications

Diesel-electric stations are constantly in a state of hot reserve, which provides for heating the water and oil in them to a temperature of 45 - 50 C. If the temperature of the water and oil is below 45 C (but not lower than 15 C), the diesel generator is considered unheated. [1]

Diesel-electric stations are constantly in a state of hot reserve, which provides for heating the water and oil in them to a temperature of 45 - 50 C. [2]

Diesel-electric stations (DES) are used as an autonomous, backup or emergency source of power supply to electricity consumers. They can be stationary, mobile (on cars, trailers, electric trains) or containerized. At the same time, as an autonomous source of electricity, a diesel unit can be effectively used only in cases where there is no access to centralized power grids, for example, in most of the northern territories of Russia, in the regions of Siberia and the Far East. If such access is available, then for economic reasons it is advisable to use the installation as a backup source of electricity. [3]

The diesel-electric station DES-40M1 consists of a D-60 R engine with a power of 60 hp. With. and generator ES-E2-4 S with a capacity of 30 kW. [4]

The UDG-50 diesel-electric station consists of a D-108 engine and an ECC-92-6M generator. [6]

The UDG-50 diesel-electric station consists of a D 108 engine and an ECC-92-6M generator. To drive the mechanisms, electric motors with a voltage of 380/220 A are installed on the crane. [7]

The diesel-electric station ESDA-500 with a power of 500 kW is a mobile type, located on two covered car trailer bodies of a MAZ vehicle. The trailers are equipped with diesel generators with fuel and oil tanks, a compressor, a control cabinet, power switches, an automation unit, and cable drums with cables for emergency power supply. The ESDA-500 station is used for emergency power supply of conventional pumps on main oil pipelines. [9]

Mobile automated diesel-electric stations ESD A are used as power stations and are installed on a trailer with a hood or on a trailer in a box body. They are produced with a power of 20, 30, 100 and 200 kW and the first or third degree of automation. [10]

The power of the diesel-electric station is spent on powering the welding transformer and electric motors that drive various units of the installation, which can operate simultaneously during the welding process. [eleven]

In diesel-electric stations and units, an improved automation scheme is used, the readiness time for receiving a full load is reduced and the ability to maintain a diesel engine in hot reserve is ensured. [12]

Next, diesel-electric stations and gas piston power plants based on cogenerator units will be considered in more detail. [13]

The power source for the crane's electric motors is a diesel-electric station DE. [15]

Engine Description

The line of six-cylinder V-shaped SMD engines is represented by engines such as SMD 60...65 and their more powerful versions - SMD 72 and 73.

According to its design features, the SMD 60 is a four-stroke power device with direct injection of diesel fuel. The main component of this engine is the crankcase. In this type of engine, it is designed to combine the cylinders into one solid block and add to them the upper part of the crankshaft housing. The required rigidity in such an engine is achieved due to the presence of partitions between the cylinders and the end walls of the crankcase block.

This engine is cooled using water. In winter, it is possible to replace water with antifreeze in this system. The system has a centrifugal water pump, which ensures the necessary circulation of liquid throughout the closed cooling system.

Lubrication system

The D-242 engine lubrication system is combined. Crankshaft and camshaft bearings, intermediate gear bushings and drive gears

the fuel pump, the connecting rod bearing of the pneumatic compressor crankshaft, as well as the valve drive mechanism are lubricated under pressure. Liners, pistons, piston pins, rods, lifters and camshaft lobes are splash lubricated.

The oil pump is a gear type, single-section, bolted to the first main bearing cap. The pump pushes the oil through the pipe and channels of the cylinder block into a centrifugal filter, where it is cleaned of foreign impurities, combustion products and wear.

And from the centrifugal filter, the purified oil flows into the radiator for cooling. From the oil cooler, oil flows into the engine line. The centrifugal oil filter housing contains valves: pressure reducer, drain and safety valves.

When starting the engine, unheated oil, due to the significant resistance of the radiator, flows directly through the pressure reducing (radiator) valve into the engine line, bypassing the radiator.

MTZ-82

The centrifugal filter safety valve serves to maintain an oil pressure in front of the filter rotor of 0.8 MPa. If the pressure increases above the specified value, part of the crude oil is drained through the valve into the engine crankcase.

Reducing and safety valves are not adjustable.

The drain valve is adjusted to a pressure of 0.25...0.35 MPa; it serves to maintain the required oil pressure in the main line of the engine. Excess oil is drained through the valve into the engine crankcase.

From the main line of the engine, through the channels in the cylinder block, the oil passes to all the crankshaft main bearings and camshaft journals. From the main bearings it goes through channels in the crankshaft to all the connecting rod bearings. From the 1st main bearing, oil passes through special channels to the bushings of the intermediate gear and the fuel pump drive gear, and to the fuel pump.

The valve mechanism parts are lubricated by oil coming from the rear camshaft bearing through channels in the block, cylinder head, drilling in the 4th rocker arm post into the internal cavity of the rocker arm axis and through the hole to the rocker arm bushing, from which it goes through the channel to the adjusting screw and rod.

Oil is supplied to the pneumatic compressor from the main oil line through drillings in the cylinder block and a special oil pipeline. The oil drains from the compressor into the engine crankcase.

Service

Maintenance of these engines comes down to the fact that constant monitoring of its operation is required, as well as timely routine maintenance, which are prescribed in the operating instructions for each engine. The manufacturer can guarantee that: the motor will work for a long time and without failure; maintain all its power indicators throughout its entire service life; be highly economical; only if the necessary maintenance specified in the instructions is provided.

Repair of SMD engines is most often resorted to due to the fact that malfunctions occur, and they, in turn, appear only due to non-compliance with operating rules. If crankcase oil is released through the exhaust pipe, then as a repair work, it is necessary to operate the engine at low or idle speed for a long time. If oil escaped through the flywheel housing, then there are two reasons for this: the self-moving oil seal was deformed, the gearbox sealing ring was cut off. As a repair, it is necessary to replace the failed parts.

SMD-23, SMD-24, SMD-31A

The design of SMD motors of this line is as follows:

• four-stroke diesel engines;
• Direct fuel injection is carried out into a chamber in the piston;
• has a liquid cooling system;
• equipped with turbocharging and an intermediate cooling system for air pumped into the cylinders.

The technical parameters of these engines also fully comply with current requirements. The liter power of the SMD 23 is 19.9 kW/l, and for the SMD-31A engine it is 18.2 kW/l. The specific metal consumption of these engines, as well as the specific fuel consumption, are also at a high level. Oil consumption due to waste is from 0.4% to 0.5% in relation to fuel consumption. Achieving such high performance was made possible due to the fact that the system uses turbocharging of air into the cylinders, and also cools the charge air. In addition, these engines also feature oil cooling of the pistons, damping of torsional vibrations, and improved temperature conditions of the diesel engine by introducing an oil-water heat exchanger.

Overall, installation and connection dimensions of D series motors of basic design

SMD-62

Installation of such engines is carried out on T-150 tractors. The unit itself consists of such parts as: a crankcase, a crank mechanism, two cylinder heads, a cooling system and a lubrication system, and a gas distribution mechanism (GDM).

The placement of the cylinders in such a motor is carried out at an angle of 90 degrees or 1.53 radians. Also, these cylinders are made as a single block with the upper part of the crankcase. To carry out the fuel purification process, this engine has two types of filters. One is intended for fine cleaning of fuel, the other for coarse cleaning. In order to clean the air entering the cylinders, the engine is equipped with an air cleaning system, which is presented in the form of paper filter elements. To start this engine, a single-cylinder gasoline starting engine is used. The transmission of rotation from this engine to the SMD-62 flywheel is carried out through a gearbox with one stage.

Attachments

The design of the tractor provides for the possibility of its aggregation with a huge number of attachments, in particular:

• 3-furrow plow;
• mole;
• various types of seeders;
• cultivator (including high-speed);
• equipment for automatic planting of seedlings;
• potato digger;
• sprayer, etc.

The number of units with which the LTZ-60 can work reaches more than 120 positions, this allows the model to be used in various sectors of the national economy.

Thus, solving a lot of utility problems becomes possible by attaching a plow blade, brush device, etc. to the tractor. Moreover, at one time even excavators were made on the basis of this machine.

Cost and reviews of the SMD engine

It is worth noting that the cost of these engines is very low. It cannot be compared with imported analogues. All components for these units that may be needed during repairs are also low in cost. It is also worth noting that, despite the long break in the production of these models, there are a lot of spare parts for them and they are not difficult to find, since previously too many of these engines were produced.

However, it is worth noting that their low cost is not for nothing. Reviews about the SMD-21, for example, are not the most pleasant. Despite the fact that major repairs were carried out once a year, the maximum speed was only 80 km/h when driving downhill and the clutch was depressed, and if not depressed, then 60 km/h. The owners also said that vibration in the engine constantly caused everything to spin up. The only plus that stood out from user reviews was fuel consumption, which was only 20 liters per 100 km.

Technical characteristics, photos and videos of the LTZ-60 tractor and its modifications LTZ-60AB and LTZ-60AV

The LTZ-60 tractor is an all-wheel drive agricultural machine with a towing class of 1.4 tons. This device, which is no longer produced today, is effectively used during spring sowing and for harvesting, plowing fields, transporting various goods, and landscaping work.

The production of the Lipetsk tractor began in 1991. It was decided to improve the previous model, the T-40, which was outdated and definitely needed improvement. The result was a fairly light and inexpensive car, very economical in fuel consumption, stable on the move and easy to operate. It could even compete with the most popular tractor model of that time - MTZ-80.

The designers provided full reverse for any gear, resulting in increased maneuverability. And the fact that automatic equipment was installed on the front axle (which is the drive axle) eliminated slipping of the rear wheels.

The hood type of the body allows easy access to the engine for maintenance. The large cabin, protected from noise and vibration, is equipped with a heating and ventilation system, and the driver can adjust the comfortable seat to his weight and height.

The ability to connect with various agricultural machines and equipment (more than 120 types, all of which are compatible with the MTZ-80) made it possible to use the tractor for any rural work, and not only. During production, several modifications of the tractor were developed to increase the possibilities of its use. After the bankruptcy of the plant in 2004 and its reorganization, this model ceased to be produced. Photo of the LTZ-60 tractor

Engine

The four-cylinder diesel engine produced in Rybinsk, which powers the base model, is water-cooled. Its power is 60 horsepower, and it “eats” very little fuel - only 8.98 liters per hour.

Transmission

The unit is equipped with a dry friction permanently closed single-disc clutch. An additional clutch is used to transmit rotation to the power take-off shaft. The four-speed gearbox has eight speeds. Its shafts are arranged transversely. The gears are locked using the clutch pedal blocking roller. Brakes are dry, band type.

rear axle transmission – gear (spur gears). This axle is equipped with a double-satellite closed differential with automatic locking. On the front axle, the main transmission is carried out using bevel spiral gears, and its differential is a ratcheted double double-sided freewheel. If the wheels slip by more than 4%, it turns on itself.

Electrics

The generator produces 700 watts of power and is equipped with a 14-volt rectifier and voltage regulator. To start the engine, an electric starter with a power of 4 kilowatts is used.

Regarding the D-260 on ZIL. MMZ (Minsk Motor Plant) at one time made several pieces for ZIL - the problem is that the engine is long and heavy and that’s the point. In practice, you can plug in a D245.30 - 156 hp (notched), but the crankshaft, flywheel, clutch, and bell have their own (9 holes for the flywheel). However, on the bison, the crankshaft is a consumable. You can look for a gearbox with a divider, I had a bull at one time and thought about it. MAZ makes agricultural vehicles with D260 with KAMAZ gearbox. IMHO it's worth looking in this direction. The D260 is lighter than the YaMZ, the Kamaz gearbox is an overdrive gearbox, and if desired, also with a divider. The only original spare parts are the bell (ask dealers) and the muzzle from the 133GYA.

Well, I don’t know about the heavy SMD, but it’s heavy, and probably 40% of the converted Zils are running in our country. Only recently they started putting 245 e but 6ka thing! and it works softer and dope just right. For some reason everyone wants to load more and attach something.

Well, long, yes. But regarding the severity, I don’t know. The D-260 weighs 700 kg, and the ZIL-508 weighs 490 kg. Only 210 kg heavier. Weight of 2 adults! And if everything is so critical, then you can put wider tires on the front and you will negate the harmful effect of excess weight on the soil.

The inline 6 rules! D-245 is smoking nervously on the side!

—Where did you manage to make so many enemies for yourself? “You don’t have to be a genius to do this.” Do your job, tell the truth, don’t fawn - and this is quite enough for any mongrel to bark at you from under every fence.
