Historical aspect

The YaMZ 236 motor was developed in 1951 on the basis of the YaAZ 204 and YaAZ 206 power units. The production of these internal combustion engines was carried out by the Yaroslavl Motor Plant, which later became Avtodizel OJSC.

During the installation and modernization process, YaMZ engines began to be permanently installed on MAZ, URAL, KRAZ trucks, K-700 tractors and some military equipment, especially tanks and all-terrain vehicles.

Technical characteristics and device

The technical characteristics of the YaMZ 236 engine have not changed much since the start of engine production. Only some technical and design elements have been added, such as turbocharging, power supply or exhaust gas systems.

Applicability

YaMZ 236 engines have become quite widely used. Thus, about two dozen brands and more than 40 models of cars, buses, military vehicles and construction equipment are still equipped with legendary engines.

URAL with YaMZ 236 engine.

The URAL-4320 with the YaMZ 236 engine has become quite popular. In addition to this brand of engine, there is also an older brother - the YaMZ-238. This motor is much more powerful, and therefore is installed on heavy construction equipment, tractors, and even strategic military vehicles.

Why have YaMZ engines become widespread? Unlike their Western counterparts, domestically produced power units are quite easy to repair and do not have a large amount of electronics, which makes repairs possible in the field.

Also, the motors have the necessary power so that the vehicle can pull a load even in the most difficult conditions. For example, sand that gets into the fuel system is not a hindrance, and it is easily removed from the engine.

So, let's look at which vehicles the YaMZ-236 power unit can be found on:

• The first in line, of course, are MAZ cars. The engines can be found on such models as: 500, 503, 504, 509, 516, 5335, 5549, 5551 and others.
• The second most widely used vehicle is the KRAZ: 255, 250, 257, 260 and 6322.
• Also installed on URAL series vehicles: 4320, URAL 5323.
• Also, the YaMZ-236 engine was also used on KAMAZ. So, the model 5320 was equipped from 1976 and 2000.

The production of medium-duty off-road trucks Ural-4320 began back in 1977. Initially, the car was produced for the needs of the army, but soon the capabilities of the truck were appreciated in the national economy - it became indispensable for the needs of the logging, oil and gas industries and in other cases when it was necessary to work in complete off-road conditions. Over the years of its production, the Ural-4320 went through several modifications, but all of them were limited to minor cosmetic changes to the cabin and the installation of different power units. Currently, production of the Ural-4320 continues, in parallel with the start of production of the new civilian version of the Ural-NEXT.

Ural-4320

Depending on the year of production, various versions of naturally aspirated V8 diesel engines were installed on the Ural-4320 truck. Until 1993, almost all models were equipped with a KamAZ-740 diesel engine, but since 1993 they began to install 11.5-liter V6 engines YaMZ-326 or 14.9-liter V8 engines YaMZ-238, developing power of 210 and 230 hp. respectively. Since 2011, all Ural-4320 have been equipped with modern, economical in-line YaMZ-536 engines with a volume of 6.7 liters and a power of 230 hp. or turbodiesel V6 YaMZ-6565 with a volume of 11.1 liters and a power of 300 hp. The transmission is a 5-speed manual gearbox with a two-stage transfer case that transmits torque to all three drive axles.

Real reviews about the fuel consumption of the Ural-4320 per 100 km.

• Oleg, Miass. Consumption in the Urals greatly depends on the cost of the engine. At our enterprise we have several Urals with different engines, mine still has an old KAMAZ engine - the consumption is about 30-35 liters, but this is only for pure mileage, without load. It can carry up to 40 liters loaded.
• Sergey, Tyumen. I work on a timber carrier Ural-43202-01, with a gross weight of 15 tons. It’s stupid to compare this car with foreign trucks - they are in completely different categories. I previously worked in a Mercedes Atego, of course there was comfort and all that. In the Urals, the concept of comfort and convenience for the driver is completely absent - but in terms of cross-country ability, hardly anyone can compete with it. The truck's consumption is high - with a trailer of 15 tons in the taiga it comes out to about 50 liters per 100 km, no less.
• Alexey, Krasnoyarsk. Before the Urals, I had a Shishiga, but the body was small, so I took the Ural. I did a complete tuning - I installed comfortable seats in the cabin, replaced the axles, installed a winch, a snorkel, installed a radio station and a couple of berths in the back. There is plenty of space in the back – you can easily stow a couple of inflatable boats, camping equipment, a supply of provisions and even an ATV if necessary. Fuel consumption depends on the terrain - if on the highway, then I fit in 30-32 liters, off-road from 45 to 70 liters.
• Konstantin, Kirov. In the Urals he served in the army - he served as a driver. I wouldn’t wish anyone to drive such a car in my life – it shakes my whole soul, Kamaz is much better and more comfortable. Diesel fuel consumption is simply outrageous - with a platoon of soldiers in the back, 50 liters, like straight out of a bush. I would never take one like this for work.
• Andrey, Krivoy Rog. A couple of years ago I got a job in an office that had a bunch of different special equipment. I received a crane on the Ural-4320 platform - what a gift. The car is, of course, passable, but because of this they sent me into every hole where it was difficult to send other cars. The consumption is huge - on the highway 35 liters, in a quarry or off-road easily 50 liters, or sometimes even more.
• Anton, Ufa. I own a Ural-4320, manufactured in 2011. The Yaroslavl turbodiesel engine, 11 liters, produces 300 horses. I will say this - this is even a lot for the Urals - all-wheel drive allows you to overcome any mud and off-road conditions. Well, the truth is that the consumption is appropriate - it doesn’t eat less than 40 liters, or even more.
• Sergey, Omsk. I used to drive a Kamaz 6x6, then the authorities bought new Urals with YaMZ-535 and YaMZ-5656 engines. I got a shift car with a 230-horsepower engine - this engine is just right for it, the power is not particularly needed, since apart from the duty crew and a small number of spare parts, I don’t drive anything special. Consumption is high - from 35 to 42 liters per 100 km, but no other car will get to where I take the guys; the same KamAZ trucks get stuck tightly, despite all-wheel drive.

Repair

Repair of the YaMZ 236 engine is carried out quite standardly for the entire series of engines produced by the Yaroslavl Motor Plant. Thus, in-line repair work is carried out directly on the car.

Depending on the make, model and design features of the vehicle on which the engine is installed, even major repairs can be performed without removing the power unit. Moreover, this is a condition that no boring is required.

The process of overhaul of YaMZ 236.

Often, if a restoration or major overhaul is underway, the engine is bored. As recent practice shows, most old cylinder blocks are not subject to boring and honing, and therefore they undergo a liner process. The block heads are quite durable, which makes it possible to go through them not often, but when overhauling, this is a mandatory procedure.

Another element with a modest lifespan is the oil pump. It is this that is often changed even before a major restoration of the power unit is carried out. Along with this part there is a water pump, which is unbearable and, as practice shows, quickly fails. But there is a way out - installing a repair kit, which is quite cheap.

Modern YaMZ-236

Cast iron was used as the base material at the plant until 2010. But later engineers and designers decided that it was time to use aluminum. Now the block and cylinder head are made from this metal, which has greatly simplified the repair of the YaMZ-236 and the boring of the combustion chamber journals. Also, the honing procedure has become much more accurate. At the same time, the block did not lose its strength. For YaMZ-236, the price in this form is 460 thousand rubles. On the secondary market you can buy copies for 50-200 thousand rubles. It all depends on the condition.
