Description of maintenance features of YaMZ 238 engines

According to the recommendations for servicing motors of the 238th model range, scheduled work must be carried out after the distance traveled, equal to no more than 20 - 25,000 kilometers. At scheduled maintenance comprehensive measures are being taken, the purpose of which is to restore the original operational properties and technical characteristics of working parts and assemblies of a diesel engine. The operating and repair manual for the YaMZ G8, developed by the manufacturer, contains a list of the main diesel maintenance activities:

Engine oil change.
Valve clearance adjustment.
Change of filtering mechanisms.
Cleaning the openings of the spray nozzles.
Adjustment of modes of the fuel pump high pressure fuel pump.
Other procedures related to the maintenance of an internal combustion engine.

The duration of operation and the reliability of the functions are directly dependent on the timely care of the diesel engine. Maintenance works are carried out for the purpose of prevention, therefore, it is necessary to adhere to the recommended deadlines.

TO types:

daily service;
MOT after break-in;
the first TO-1 (carried out after 500 working hours);
second TO-2 (after 1000 hours);
seasonal maintenance - carried out during the change of seasons (preparation for winter, transition to summer operation of the motor).

Maintenance of the YaMZ 238 lubrication system

The duration of the operating life of YaMZ 238 engines depends entirely on the frequency of lubrication operations. The grade, quality, brand of oil for the YaMZ 238 engine also play important role in the duration of the operation of a complex device.

How to check the engine oil level:

Clean the filler hole of dirt accumulations.
Remove the oil dipstick from the engine housing.
Wipe dry with a lint-free cloth.
Insert the dipstick in its original place and pull it out again.
Determine the oil level.
A mark between the designations "H" and "B" (lower and upper levels) is considered normal.

Important: If the engine was running before checking the engine oil level, a check measurement is carried out no less than 5 minutes after it was turned off.

If, as a result of measuring the oil volume, the mark is closer to the lower value, it is recommended to add the required amount of fresh portion lubricating fluid into the engine through the filler hole. The filler neck is located in front of the engine behind hydraulic clutch fan.

In the process of measuring the level, the condition of the lubricant is monitored. To do this, apply a few drops of oil on a paper napkin. white color and study the following engine oil parameters:

oil stain color;
degree of transparency;
the presence of foreign inclusions in the form of black dots and metal chips.

If deviations in the quality of the oil from the norm are detected, it is necessary to replace the used fluid, as well as flush the diesel engine.

Motor oils for diesel engines YaMZ 238

M8DM oil is intended for use in diesel engines X. The basis for the production of this material is sour oil. To improve beneficial features, specifications and increase the effectiveness of this lubricant, it contains special additives - high-quality additives. This allows you to protect the working units and parts of the power unit from harmful effects corrosion, accelerated wear, premature deformations resulting from sharp jumps in temperature. When using M8DM engine oil, the diesel engine runs stably and smoothly throughout the entire operating period.

Motor lubricant M-10DM is a high-quality lubricants low-ash type. This brand recommended for use in summer period. Scope of application - diesel engines and engines equipped with a turbocharger operating in difficult conditions increased complexity. When using oil of this brand in internal combustion engines without turbocharging, a sharp increase in the interval between service replacements of the lubricant was noticed.

Few diesel engines can boast such a solid " track record", like YaMZ-238. This engine has become the "heart" of many thousands of MAZ, KrAZ, Ural trucks familiar to everyone and everyone; tractors "Kirovets" and "ChTZ"; combines "Don" and "Polesie". And a large number all kinds of highly specialized equipment, boats, diesel power plants. YaMZ-238 is extremely reliable and unpretentious in operation, which provided him with a “long-liver career”: the engine launched into series in the early 60s continues to roll off the assembly line of the Yaroslavl Motor Plant today. Despite the fact that a lot of more modern "successors" appeared in the assortment of the plant.

Yaroslavl Automobile Plant. Until 1958, this was the name of this enterprise, which produced trucks, buses and trolleybuses. In many things, YaAZ became a pioneer. Here, in the 1920s, the production of the first heavy-duty vehicles (from 3 to 7 tons) in the Land of Soviets was launched. In the 1930s, the first dump trucks in the USSR left the assembly line of the plant; one and double-decker buses and trolleybuses.

The first diesel engine in the Union was also produced in Yaroslavl. Here, by the end of the 30s, diesel engines MD-23 domestic development for trucks and tractors were tested and prepared for launch in a series. But mass production diesel engines was established only two years after the end of the Great patriotic war. During the war years, YaAZ gave the front light tracked tractors for artillery.

Since 1947, the plant has launched mass production of families of 2-stroke four- and six-cylinder diesel engines YaAZ-204 and YaAZ-206 with power from 110 to 220 hp First of all, the developers of new families of motors - and YaMZ-238 - relied on the experience of their production and operation.

During 1958-1961, a group of scientists led by the outstanding Soviet designer and inventor Georgy Dmitrievich Chernyshev created and prepared for the launch in a series the best diesel engines in the world at that time: powerful, versatile, reliable and trouble-free. And also economical (for that time). For the development of these four-stroke six- (YaMZ-236) and eight-cylinder (YaMZ-238) engines with power from 180 to 500 hp. was awarded the State Prize of the USSR, and the plant was awarded the Order of Lenin.

Since that time, the story of Yaroslavsky ended car factory(production of trucks was transferred to Minsk), and the history of the motor plant began. The scale and volume of production of universal diesel engines that were deployed here in Soviet time, strike the imagination. It is estimated that in total more than three hundred models of trucks, buses, tractors, and other vehicles were equipped with YaMZ engines.

In our time, YaMZ has retained the function of a full-cycle enterprise: with its foundry, forging press, thermal, welding, galvanic, painting, hardware, mechanical assembly, assembly and testing, tool, repair production. With energy facilities, transport and storage services, a developed network of distribution points and after-sales service, with workshops for small machine tool building and non-standard equipment. YaMZ is part of the GAZ Group holding.

So, YaMZ-238 is a four-stroke eight-cylinder diesel engine, with a classic V-arrangement cylinders, with direct injection fuel, compression ignition and liquid cooled. Available in both conventional "atmospheric" and turbocharged versions.

In total, at the present time, the assortment of the plant, set out in the current official price list on the YaMZ website, includes 25 various modifications YaMZ-238 engine. Whole line turbocharged versions (DE series, for dump trucks and trucks, truck tractors MAZ, KrAZ, Ural; tractors and timber trucks) have been modified to Euro-2 standards. In total, the general list of modifications of this motor has 86 positions.

Varieties of motors of the YaMZ-238 family and their features

YaMZ-238 is the most demanded diesel engine of the Yaroslavl Motor Plant on the market. In technological terms, it is not much different from the YaMZ-236 series of six-cylinders (first of all, the number of cylinders, of course). Power basic versions YaMZ-238 varies from 180 hp. in the de-forced version of the YaMZ-238 / G2, up to 240 hp in the YaMZ-238 / M2 modification.

YaMZ-238 / Euro-0 Turbo engines are forced YaMZ-238 / M2 engines. They differ from the usual "atmospheric" not only in the presence of a turbine. During the development of this family, a number of design changes were made to the cylinder block and the cylinder-piston group.

The high-pressure fuel pump and crankshaft have also been redesigned. The assortment of the plant includes YaMZ-238 models with flywheels for the installation of 2-disk or single-disk clutches; with right-hand controls (by order from South Africa), and other constructive solutions, for the needs of each specific technique.

Motors of the YaMZ-238 / Euro-1 Turbo series are modified Euro-0. The features of their configuration is the installation of a liquid-oil heat exchanger, a fan clutch and air ducts to the charge air cooler mounted directly on the engine.

YaMZ-238 / Euro-2 Turbo engines, DE series, were the result of further modernization of the turbocharged YaMZ-238. The motors of this series received a modernized modern high-pressure fuel pump.

The device and layout of the main elements of YaMZ-238 engines

Eight cylinders YaMZ-238 are arranged in two rows, in a V-shaped pattern, at an angle of 90 degrees. Inlet fuel mixture and exhaust gases are provided by 16 valves.

The basis for the installation of all units and parts is the cylinder block, which is cast from low-alloyed gray cast iron. In the tides-bosses on the walls of the block, a system is provided oil channels, supplying lubricant to the bearings of the distributive and crankshaft; to the oil filter and to the liquid/oil heat exchanger.

A closed power belt is formed around each cylinder seat by the walls of the water jacket. Together with special ribs, the power belt fastens together the upper and lower plates (parts of the cylinder block), giving the entire structure the desired degree of rigidity. In the transverse walls of the block there are five nests with liners for the crankshaft main journals. As well as five bores with bronze bushings in which the camshaft rotates.

The cylinder heads of the YaMZ-238 engine are four-block, cast from gray cast iron with a polished surface and annular grooves. The gas joint of the head, block and cylinder liners is sealed by a single gasket with 19 sealing elements. The cylinder heads house the intake and exhaust valves with springs, rocker arms, rocker arms and injectors.

The inlet valve seats are made from a special grade of cast iron, while the exhaust valve seats are cast from a special heat-resistant alloy. Seats and metal-ceramic cylinder bushings are finally processed during their pressing into the head.

Crank mechanism

Pistons made of aluminum eutectic alloy are placed inside the cylinder liners, which are coated in YaMZ-238 with a special phosphated layer to enhance wear resistance. Oil is supplied to the piston from a special fixed nozzle. The groove for the upper (compression) ring is made in an insert made of heat-resistant cast iron of a special grade, such as "niresist". The number of rings, depending on the modification of the YaMZ-238 engine, is three or four. piston pin- nitrided, with an increased outer diameter.

The I-section steel connecting rod has an oblique lower head connector. The connecting rods are finished after they are assembled with the cap, so the rod caps are not interchangeable. Replaceable liners are mounted in the lower head of the connecting rod, and a steel-bronze bushing 56 mm in diameter is pressed into the upper head.

Flywheels on YaMZ-238 are used in two types. Brand "K", for a ring gear with a module of 4.25. And brand "H", designed to work with the gear rim of the module 3.75. Flywheels are supplied complete with ring gears and are not interchangeable. The cast-iron flywheel is attached to the crankshaft with bolts, under which a high-strength steel plate is installed (one for all bolts). With respect to the crankshaft journals, the flywheel is fixed exactly with the help of two special pins.

Crank mechanism YaMZ-238

The steel crankshaft of YaMZ-238 engines is manufactured by hot stamping. All surfaces of the crankshaft are additionally processed and covered with a nitrided layer with a thickness of at least 0.35 mm. The crankshaft is equipped with five main bearings and four connecting rod journals. The system for balancing the crankshaft and saving (unloading) the main bearings includes, in addition to counterweights on the cheeks of the crankshaft, also two external masses at the front and rear ends of the crankshaft.

The crankshaft of YaMZ-238 engines of the BE and DE series is equipped with a cone at its front end, on which a hub is fixed, a liquid damper torsional vibrations and a special pulley.

The gas distribution mechanism of the YaMZ-238 engine

What elements does the gas distribution mechanism on YaMZ-238 consist of: this is a camshaft equipped with a drive gear and bearings; pushers with special axles; rods and rocker arms with adjusting screws; rocker axles; valves with springs, fasteners and guide bushings.

The camshaft is made of steel, forged, the bearing journals and cams of which are hardened by HDTV to increase wear resistance. It is installed at the top of the crankcase of the cylinder block. It is driven from the front end of the crankshaft, by means of special helical gears. The other listed elements of the gas distribution mechanism are also stamped, made of steel.

The inlet and outlet valves of the gas distribution mechanism are made from special heat-resistant alloys. The working chamfers of the valves are additionally welded with a particularly heat-resistant alloy of the Stellite type. Tips made of alloyed steel are welded to the rods.

Engine lubrication system YaMZ-238

The lubrication system at YaMZ-238 is of a mixed type, with a "wet" sump. Oil pump, having a working capacity of 140 liters per minute, sucks oil through the intake pipe from the lower part of the crankcase and supplies it under pressure to the liquid-oil heat exchanger. From where, through the bypass valve, the oil is driven through special channels to the bearings, pushers and other working surfaces of the engine.

When the oil pressure rises above 520 kPa (5.2 kgf/cm2), excess oil is drained through the oil line back down the crankcase. To clean the oil from waste products, the presence of oil filter and an additional centrifugal oil filter.

The fuel supply system of the YaMZ-238 engines is of a split type. Its components are as follows: high pressure fuel pump (with built-in regulator and corrector); fuel pump; nozzles; coarse and fine diesel fuel filters; low and high pressure fuel lines.

The functioning of the YaMZ-238 power system is as follows. Diesel fuel is sucked from the fuel tank by the fuel priming pump, while passing through the original filter coarse cleaning fuel. Further, the fuel reaches the fine filter through the fuel line, passes through it and enters the high pressure fuel pump.

The injection pump, like a real fuel distribution station, in accordance with the order of operation of the cylinders, drives the fuel through the high pressure fuel lines to the injectors. Through which it is sprayed into the cavity of the cylinders. Through bypass valve V fuel pump and a jet in the fine filter, excess diesel fuel, together with the air that has entered the system, is discharged through a special fuel line back to fuel tank. The same function is performed by the fuel line, which removes excess fuel that has leaked into the cavity of the injector spring.

Specific application of YaMZ-238 engines: yesterday and today

Despite the abundance of modifications, design and technological diversity, YaMZ-238 engines, in most cases, are interchangeable with their predecessors, already removed from the assembly line. For example, variations of the YaMZ-238 / M2 model (of which there are 19 pieces - especially for Urals, river boats, MAZs, KrAZs, etc.) are interchangeable without problems not only with YaMZ-238 / M, produced until 1988, but also with YaMZ-238, the supply of which ceased in 1985.

Malfunctions YaMZ-536

Here you need to monitor the state of the USR, where carbon accumulates and the valve is stuck. This is solved either by regular cleaning or plug EGR and ECU firmware for operation without this valve.
Also, the motor may consume oil. In this case, check the valve guides, they may wear out and oil will flow through them.
The turbine serves approximately 250-300 thousand km, plus or minus. By this run, you need to control its condition so that the dead turbine does not pull other expenses with it. In the event of a turbocharger failure, it is advisable to install an analogue of BorgWarner B2G. There are cases of turbine failure even up to 50 thousand kilometers.
In general, the motor does not have a very positive reputation, it is less reliable than the older brother YaMZ-650 and requires a more careful attitude in everything. Do your best on your own: pour only quality fuel, quality oil, maintain regularly, do not save, and perhaps problems will bypass you.
Autodiesel says that an oil change is required after every 30,000 km, but if the sulfur content in the fuel exceeds 0.2%, then the oil needs to be changed 2 times more often.

Engine number YaMZ-536

The number is stamped on the cylinder block on the left under the generator.

Tuning YaMZ-536 engines

Chip tuning

Motors that have programmatically underestimated power can be pumped up to a full 312 hp with firmware. To do this, you just need to contact a tuning company dealing with YaMZ engines and they will upload the firmware for your engine.

Motor oils for YaMZ diesel engines

Yaroslavl Motor Plant in the middle Russian manufacturers autotractor diesel engines for more than 60 years has been a leader in the formation of the necessary requirements for motor oils.

The year 1940 was marked by the release of the YAZ-204 engine, it was at this moment that it was necessary to launch completely New Product, because cars with the new YaAZ-204 engine, even on the most the best oils without additives, they did not have time to turn out more than 160 hours! They failed after 100-150 hours of operation. coking piston rings or a complete loss of mobility - that's what was the stop of the motor. The sulfur contained in the fuel, and naturally the oxidation products of non-polymerization, formed from the oil due to exposure to high temperatures, strongly coke the piston rings in the grooves.

It is worth understanding the fact which oils form strong oil films, do not prevent coking of piston rings, do not form resinous deposits, interfere with the formation of deposits in the exhaust system, in addition, they exclude carbon deposits on candles; they do not have amazing anti-corrosion and anti-wear properties. How much oil is in the MAZ-504 YaMZ-238 engine: 240: 29.0: Engine oil tolerances: summer: M-10V2, M. Krapiva, synthetic oils. they are perfectly adapted to new types of fuel and are not environmentally friendly.

By the end of the 50s, the Yaroslavl Motor Plant produced two YaMZ-236 diesel engines, not YaMZ-238. This diesel YaMZ engine 238 turbo has a fairly wide account of using inexpensive engine oil and transmission oil. How to change the oil in Daewoo engine V Daewoo Nexia how many liters. For these engines, oils with more effective additives were useful. Then the new production of YaMZ diesel engines necessitated an increase in the level operating parameters motor oils used in almost all engines.

Currently, YaMZ has a standard RD 37.319.034-97, which spells out what remains to be done by our client with the requirements for the physical and chemical non-operational properties of motor oils used on YaMZ engines. A similar standard establishes the procedure for admitting motor oils to YaMZ engines. How much oil should be poured into a Renault gearbox. How many liters; Oil volume (l.) 1.5: SOHC: How many liters; Fluid in brake system Daewoo. For this purpose, the document also additionally spells out sets of methods for testing motor oils, which are subjected to oils of different groups.

According to the systematization of motor oils (API - South American Petroleum Institute). four groups of YaMZ oils correspond to the following four classes:

Ural timber carrier Changing the oil in the engine. How many liters of oil should be poured into the engine. Yamz-238 first person

Ural timber carrier, Yamz engine—238 , drain oils, washing the centrifuge, filter, etc. thermostat is not a faucet trailer.

How to change the oil on a T-150K tractor with YaMZ-236(238)

April 2014. Seasonal change oils V YaMZ engine-236 on the T-150K tractor. Oil used for replacement.

According to the Russian systematization of motor oils GOST 17479.1-85 (by designation not the level of operational parameters) used in cars, tractors, diesel locomotives, agricultural, marine, road and other equipment, the first three groups are equivalent to G2, D2 not E2.
