KamAZ trucks have a set of exceptional characteristics. First of all, these include increased wear resistance. Such vehicles are designed to cover long distances, amounting to hundreds of thousands of kilometers. Additional advantages are the trucks’ unpretentiousness to the quality indicators of the fuel fluid. But despite this, long-term operation can be ensured only through proper selection of oil and maintaining it at the required level.

Oil for KAMAZ axle. What and how many liters to fill.

Oil in the KamAZ axle is one of the most important conditions for long-term operation. For the correct and durable operation of the mechanisms, the volume of oil in the KamAZ axle must correspond to the established level.
The brand of oil used, as well as its timely replacement, is also decisive. How much oil to pour into the KAMAZ axle

How many liters of oil are poured into KamAZ axles? Design features establish different volumes of lubrication in the main gear housings. All-terrain vehicles produced by the Kama Automobile Plant are equipped with a front drive axle, which also requires lubrication. Its cavity holds 5.3 liters of oil. In addition, the steering knuckle assemblies need lubrication.

The presence of a center differential mechanism determines how much oil to pour into the middle KamAZ axle. Seven liters of lubricant must be placed in the gearbox. The center differential attached to it also needs an additional 750 grams of oil.

The plant has about 80 types of bridges, they all have a similar structure, but there are exceptions. Therefore, in any case, be guided by the level of the control holes.

In the middle part of the crankcase there is a control hole, which is used to determine how much oil to pour into the KamAZ rear axle. The control hole plug is unscrewed and oil is added to the filler hole until it appears in the control hole. The check should be carried out on a horizontal platform, you need to make sure that the wheels are at the same level: otherwise it is impossible to correctly determine the required level.

Which oil should you choose?

Drivers are not always responsible about what kind of oil should be poured into the KamAZ axle. However, the wrong choice of lubricant will lead to premature wear of moving parts and failure of the machine’s chassis components.

The most preferred oil for KamAZ axles is 75W-90 or 80W-90. You can also successfully fill domestic oil into the rear axle of a KamAZ TAD-17i brand. It provides good lubricating properties, but is unstable to low temperatures and tends to thicken in severe frosts, making it difficult for mechanisms to operate. However, most drivers use it due to its low cost.

It is better to use KamAZ axle oil from well-known foreign brands. Synthetic motor oils 75W-90 Shell Spirax S6 AXME and Castrol Syntrax Long Life have a long service life and perfectly protect the rubbing surfaces of gears, bearings and shafts. They also work excellently in temperatures of -40 degrees without losing their fluidity. The maximum ambient temperature for their use is 35 degrees.

Gearbox oil of the KamAZ middle axle 80W-90 is also used. They are used in temperate climates, since its operating temperature range is from + 35 to -25 degrees Celsius. One of the best in this category is Mobilube HD. It perfectly lubricates components subjected to heavy loads. For adherents of semi-synthetic oils, Esso Gear Oil GX, also 80W-90, is suitable.

In climate zones where high temperatures prevail, the best choice is 85W-90 oil. It retains its thickness in 45-degree heat. The minimum thermometer reading for this category is -12° C.

Change of oil

The first check of the oil level is carried out after 1000 km. mileage, the second - after another 4000 kilometers. Subsequent monitoring and topping up must be carried out every 8,000 kilometers, and after 50,000 km. A complete oil change must be performed in KamAZ axles. To do this, the gearbox is warmed up, allowing the car to run. Then unscrew the plugs of all three holes: filler, control and drain. After all the used lubricant has flowed out, the gearbox cavity is washed and the bottom plug is tightened. Then oil is poured into the KamAZ front axle through the upper hole until it appears in the control hole. Then the remaining plugs are tightened.

for the mess, don’t blame everything.

A power unit with insufficient lubricant is much more susceptible to wear during operation and is more likely to fail. Using non-recommended oils and intermittently changing them increases wear on internal engine components.

Properties of oils and their differences

Modern motor oil

Made from mineral and synthetic base oils and additive packages. Thanks to this, engine oil differs in thermal-oxidative abilities, viscosity, temperature and performance characteristics. Choosing a brand of motor oil depends on your preferences and needs. It is worth highlighting the main characteristics of motor oils poured into the KamAZ 740 engine: Viscosity level. Diesel power units use oils with a high level of internal friction; - operational properties. For engines with a gas turbine system, special oils are used; Viscosity class.

With timely replacement and compliance with the required amount of oil poured into the engine

KAMAZ, you can achieve maximum engine life.

Which oil is suitable for the KAMAZ engine

Amount of oil to replace in the engine

The durability and reliability of the power unit of cars from the Kama Automobile Plant depends precisely on what kind of oil is poured into KAMAZ engines. They are known for their reliability, durability, unpretentiousness and extended service life. And the lubrication system of automobile engines played a significant role in this. Depending on the brand of the unit and its design, different lubricants are used.

Today there are a large number of different brands and types of oils on the market. And here the main thing is to make the right choice, because the main indicators of the engine’s performance will depend on this. Oil for the KAMAZ engine is selected in strict accordance with the engine specifications. And every owner of a truck of this brand must decide what oil to fill into the Kamaz engine, based on the manufacturer’s recommendations. Oil for KAMAZ engines should be used in group CD according to API classification or group D in accordance with GOST 17479.1. KAMAZ engine oils are most often used in accordance with international classifications from SAE 15W-40, for all seasons of use, to SAE 5W-40 or 5W-30, for areas with cold climates and severe operating conditions. KAMAZ engine oil for seasonal work or for maintenance in a temperate climate area can be used with SAE 20W.

What oil is better to pour into a Kamaz engine?

One of the most common oils for Kamaz diesel engines is KAMAZ SAE 15W40 API CI-4/SL K10-40.50 oil. What kind of oil to pour into the KAMAZ engine is chosen in each specific case by the mechanics themselves who service the vehicles. Sometimes, KAMAZ SAE 15W40 API CI-4/SL OPTIMUM KO15-40.50 engine oil is used for Kamaz engines, which has improved characteristics. Oil for the KamAZ 740 engine is selected based on the future operating conditions of the vehicle, most often it is Lukoil-Super (SAE 15W-40, CE/SG) or Lukoil-Super (SAE 15W-40, CF-4/SG). The brand of oil for the KAMAZ engine has a serious impact on the operation and performance of the engine. And its durability and reliability depend on what kind of oil is poured into the Kamaz engine. KAMAZ engine oil grades CES 20078, 20076 have improved friction properties and contribute to less wear of rubbing parts.

Modern engines of the Kama Automobile Plant, which meet modern environmental standards, require special lubrication. Oil in the Euro 3 KAMAZ engine is poured from Lukoil Super series with different viscosities, since the principle of operation of the power unit with supercharged air is fundamentally different in design from atmospheric. KAMAZ turbo engine oil Lubri-Loy15w40 API CJ-4/SN, CES 20081, Lubri-Loy API CI-4/SL Multi-Grade or CES 20072 contributes to the durability and reliability of power units.

Reviews

Vasily, Tomsk. KamAZ 65115 is an inexpensive and economical truck, easy to maintain despite the factory defects. Sometimes the body lift jams due to a defect in the fluid release valve in the hydraulic system. On the other hand, I have a restyled version of 2010, with an engine that is not afraid of overloads, unlike foreign cars. Lower fuel consumption (minus 10%) and an extended service interval - that’s all about my KamAZ 65115.

Alexey, Taganrog. I work on KamAZ 65115 with a diesel engine 740.11.260 with a power of 260 hp. With. A rather voracious and noisy unit, sensitive to overheating and prone to oil burning. It is forbidden to fill in antifreeze due to possible pump failure, so only antifreeze.

Lubrication system in Cummins diesel engines

Do-it-yourself oil change in a VAZ-2114 engine

The main parts that make up the lubrication systems of all diesel engines are the oil pan, the oil cooler, and a system of channels that distribute oil to all moving mechanisms.

Sometimes units can be equipped with electric oil pumps, which drivers use to pre-lube the engine (before starting it) and increase the pressure to operating levels.

Oil pan

- This is an oil reservoir. The most common types of pans found in diesel engines are aluminum, cast iron or steel (stamped) pans. It is equipped with a rubber-metal oil dipstick for checking the oil level and an oil deflector that prevents oil from splashing onto the connecting rods. The walls of the pan remove heat from the oil, cooling it slightly. Oil sediment settles to the bottom of the pan.

Oil pump

– designed to take oil from the sump and supply it further to the oil cooler, as well as to maintain the required pressure in the lubrication system of a diesel engine. The drive is provided directly, via an intermediate shaft or a camshaft.

Diesel engines use gear and rotary pumps (externally geared, internally geared or planetary), while truck-type diesel engines use gear scavenge pumps. They ensure a constant supply of oil when the machine is operating on a slope.

Oil cooler

– designed for additional oil cooling. It becomes possible to reduce the size of the oil pan, resulting in much less oil coming into contact with hot engine parts during sudden changes in engine tilt. The oil cooler is a radiator - a system of copper tubes enclosed in a sealed housing.

Oil flows through the tubes, and coolant flows into the housing. Moreover, the directions of flow of oil and liquid are opposite. At the inlet of the oil cooler there is a pressure reducing valve designed to regulate pressure. The valve is set to a pressure of 414 kPa.

Oil filter

– installed at the outlet of the oil cooler. Modern diesel engines use full-flow and part-flow engines. The former completely allow the oil flow coming from the oil cooler to pass through them. The latter are only part of this flow.

The rest of the oil goes back into the pan. Thus, oil purification is ensured in several cycles. There is a bypass valve at the oil filter inlet.

The Cummins diesel engine duct system consists of the main oil duct and its branches, the oil supply duct and the turbocharger line. Oil is supplied to the turbocharger and drained back into the sump through flexible tubes made of neoprene rubber, nylon and other synthetic materials.

The main oil line supplies oil to all moving mechanisms - main and connecting rod bearings, crankshaft and camshaft, valve mechanism, piston and cylinder blocks, and others. Oil pressure in the lubrication system is maintained by holes of a given cross-section.

How much oil is required for a UAZ engine

Before draining the old one or filling in a new motor lubricant yourself, you need to familiarize yourself with the manufacturer’s advice on how much to fill when changing. Since all cars have different power, different modifications, engine size, this value will differ. Let's consider the parameters for engines of domestically produced cars, namely UAZ.

How many liters of oil are in a UAZ Patriot engine?

To change the lubricant for the UAZ engine of the Patriot model, seven liters are needed. In terms of viscosity, the most optimal options are 10W-40, 5W-30 or -40.

After how many kilometers, or what period of time, you can change the lubricant in the UAZ operating unit, you can find out from the operating instructions developed by the manufacturer. It states that after draining the old one, filling in the new one is done every 15,000 kilometers, at least once a year.

How much oil should be poured into a truck engine?

The engines of trucks, just like cars, require modern replacement of the lubricant. This procedure can be carried out independently, but you need to know how much lubricating fluid is required. Every car owner should clearly understand that the lifespan of the main unit of his car depends on timely oil changes, and change intervals should be monitored.

KAMAZ

What is the amount of lubricating fluid in the KAMAZ 740 and 5320 engine? According to the advice specified in the operating requirements, for stable operation of the engine, the required volume is 28 liters, and replacement should be made every 16,000 kilometers or after 250 engine hours.

Video of oil change in KAMAZ:

ZIL

Information on how many liters of oil are in the ZIL 130 engine is contained in the operating instructions developed by the manufacturer. This parameter is nine liters. The manufacturer also recommends that the lubricant should be changed every 6-10 thousand kilometers.

This measure, taken by the owner of the ZIL 130 car, will extend the life of an important unit

Gazelle

The manufacturer who created the operating instructions indicates the amount of lubricant in the Gazelle 405 and 406 engine. This value is 5.4 liters. This is the amount that should be adhered to when making a shift. The mileage that the machine travels from replacement to draining the old one and refilling the new one is 15,000, but you should focus on the load during operation. Service center employees servicing these cars recommend replacement every 7-8 thousand kilometers.

How much oil is in a Gazelle Cummins engine? This question worries many owners of the updated GAZelle model. Despite the fact that there is only one manufacturer, this modification has a more powerful engine. The amount of lubricant required is 5.7 liters. Recommendations for the period and kilometers traveled are similar.

GAS

Let's figure out how much lubricant to pour for stable operation of the gas 53 unit. For the GAZ-53, the displacement of the lubricant is eight, and replacement is carried out every 10,000 kilometers.

Advice! Sometimes, for prevention, you should fill in a mineral lubricant with additives and drive it for about 2,500 kilometers. It will help flush the engine. After this, refill with synthetic or semi-synthetic.

It is worth paying attention to the fact that manufacturers recommend draining the old lubricant and adding new lubricant every fifteen thousand kilometers. But be sure to take into account the fact that the cars are operated in city traffic jams, wear and tear occurs faster

Therefore, this gap should be reduced by at least half.

The Kamens engine lubrication system provides lubrication and cooling of the moving parts and mechanisms of the system - bearings, gears, and cylinders.

A lack of oil in the engine can lead to breakdown and failure of the entire system, so it is extremely important to promptly diagnose and lubricate the engine, as well as monitor the sufficient oil level. The volume in a Kamens engine (the capacity of the engine lubrication system) depends on several characteristics: the number of cylinders, engine displacement and type of oil pan.

The volume in a Kamens engine (the capacity of the engine lubrication system) depends on several characteristics: the number of cylinders, engine displacement and the type of oil pan.

Oil volume in a 4-cylinder Kamens engine (standard):

Small capacity tray – system capacity 10 l; pallet - 7.9 l.

• Hanging tray – system capacity 13 l; pallet – 11 l.
• Aluminum tray – system capacity 15 l; pallet – 13 l.
• Large capacity tray – system capacity 18 l; pallet – 16 l.

Oil volume in a 6-cylinder Kamens engine (standard):

• Small capacity tray – system capacity 13 l; pallet – 11 l.
• Hanging tray – system capacity 19.5 l; pallet - 17.5 l.

• Standard type tray – system capacity 16.7 l; pallet - 14.2 l.
• Hanging tray – system capacity 19.7 l; pallet - 17.5 l.
• Large capacity tray – system capacity 26.4 l; pallet - 23.9 l.

Kamens marine engine oil capacity is 15.1 liters (16 quarts).

If the type and capacity of the oil pan are unknown, you can:

• Contact your Cummins representative.
• Determine the oil pan volume using the engine serial number using the QuickServe OnLine system.
• Fill the pan with the minimum amount of oil specified for this engine type. Next, add 1 liter at a time to the top mark on the dipstick.

Characteristics of Kamaz-740

Oil movement in the Kamens lubrication system

From the oil pan, oil enters the oil pump through the intake pipe. Next, the oil is supplied to the inlet of the oil cooler.

In case of increased pressure, excess oil flows back into the pump (3.9 L and 5.9 L engines) or into the sump (4.5 L and 6.7 L engines). Next, the oil enters the filter inlet, the bypass valve of which opens if the pressure drop across the filter is above 345 kPa.

After being cleaned in the filter, the oil enters the lubrication system - the main line, the injector channel and the turbocharger line. The main oil line passes through the cylinder block next to where the oil flows to the main bearings and crankshaft. From the main bearings there is a branch to the camshaft and piston cooling nozzles.

We list some possible reasons leading to a malfunction of the lubrication system:

High oil pressure. The pressure regulator valve is stuck in the closed position.

Low oil pressure. It is important to find out the conditions under which the pressure decreased. If after changing the oil, this may be due to its high level in the sump, since the connecting rods during operation are immersed in it and saturated with air, which leads to a decrease in pressure

Low oil levels can cause short-term loss of pressure when operating on slopes and turns. A clogged oil filter causes a gradual decrease in pressure by 69 kPa. Poor fastening of the intake tube leads to a decrease in pressure during startup. A decrease in pressure over a long period of time may indicate wear of the bearings or oil pump. Operation malfunction.

Presence of impurities in the oil (fuel, coolant). Mixing oil and coolant is usually caused by a leak in the oil cooler.

Reliability, problems and repair of KAMAZ 740

The production of engines for trucks at the Kama Automobile Plant began in 1975 and this was the first internal combustion engine for KamAZ vehicles. This engine has an 8-cylinder cast iron V-shaped cylinder block with a camber angle of 90° with a cylinder bank offset of 29.5 mm and with wet cast iron liners. The block is equipped with a steel crankshaft with a piston stroke of 120 mm, the diameter of the main journals is 95 mm, and the diameter of the connecting rods is 80 mm. The connecting rods are made of steel (225 mm long), the pistons are made of aluminum (their height is 75.7 mm), and they have a combustion chamber offset of 5 mm from the center. Piston pin diameter 45 mm. In turbo versions, the pistons are cooled using oil nozzles installed in the cylinder block. Oil pressure on KamAZ 740 is 4.0-5.5 kgf/cm2.

Separate cast iron heads are installed on top of the block for each cylinder separately, each cylinder head has 2 valves. The diameter of the intake valve plates is 51.6 mm, and the exhaust valves are 46.6 mm. The camshaft is located in the cylinder block and operates the valves through rods, pushrods and rocker arms. The camshaft drive is gear driven from the crankshaft. On the base Euro-0 engine, the camshaft characteristics are as follows: phase 242/256, lift 14.2/13.7 mm. Adjustment of valves on KamAZ 740 is required as necessary, valve clearances: inlet 0.3 mm, exhaust 0.4 mm. The valve adjustment order is: 1-5-4-2-6-3-7-8. For this internal combustion engine there was a YAZDA 33 pump and 33-03/10 injectors, later they were repeatedly changed to a variety of versions (see below for more details).

Euro-1 engines are distinguished by their crankshaft, pistons, piston pins, piston rings, modified head, turbocharging without intercooler, YAZDA 337 pump, 273 injectors. Euro-2 engines with a stroke of 120 mm use a crankshaft with a different flywheel mount, pistons from Euro-1, as well as an air intercooler. There are also Euro-2 engines with a piston stroke of 130 mm, which gives a displacement of 11.76 liters. There are pistons with a height of 70.7 mm, their liners, and the piston pins are still old. Diesels for Euro-3 are created on the basis of Euro-2 and have their own more durable heads, differ in crankshaft, piston rings, 274 injectors. Kamaz Euro-4 engines differ in pistons, piston pins, rings, heads with a Common rail injection system, the presence of SCR- catalyst. Versions without SCR are environmentally suitable for class 4 (Rules 96-02).

KamAZ 740 Euro-4 vehicles have a Bosch CP3.4 injection pump with an injection pressure of up to 1600 bar. These motors are controlled by a Bosch EDC7UC31 ECU.

These engines are equipped with two turbines TKR-700-01 and TKR-700-02 (their analogues: CZ K27-145, CZ K27-49, TKR 7S-6). For versions 7403 there were turbochargers TKR 7N1K-01 and TKR 7N1K-02.

KamAZ-740 malfunctions

1. Cracked heads in the injector area. A popular problem on Euro-2 engines, which happens even on new engines (up to 100 thousand km) due to the characteristics of the cylinder head. The problem was solved using Euro-3 heads. 2. Wear of liners. Another problem is Euro-3 engines, which need to be checked every 50-100 thousand km and replaced if necessary. Sometimes it turns over even before 100 thousand km. 3. It gets warm. Look for the reasons in the radiator, which needs cleaning from time to time, as well as in thermostats, fluid coupling, perhaps a problem in the ignition, in the liners or in the heads. Overheating can lead to cracks in the liners. 4. Smokes: - white smoke - there is water in the tank or coolant is entering the cylinders. - blue smoke - oil enters the cylinders. — black smoke — a fuel problem, look at how the pump is configured. 5. Knock. The reasons should be sought in injectors, unregulated valves, ignition, liners, crankshaft, perhaps the problem is in incorrectly selected pistons, in piston pins. 6. Troit. First of all, look at the pump, filters, pipes, nozzles, check the spark plugs, most often the dog is buried here. Engines with Euro-3 have an oil pump that runs for about 150 thousand km. Motors with Bosch electronics for Euro-2 do not like frosts and have difficulty starting when they occur. On Euro-2 and Euro-3 engines the crankshaft often bursts. ICEs under Euro-3 are characterized by increased wear of valve guides. In general, use good oil, change it regularly, maintain the car regularly, try not to overload it, and then the engine will work normally.
