  4. The device of the main mechanisms: engine, transmission, body, clutch, brake system, air suspension.
  5. Electrical equipment.
  6. Malfunctions and ways of their elimination.
  7. Frequency of maintenance.
  8. Rules for storage and transportation.


The owner's manual tells you where to find the frame number. The frame number is located on the top right side of the channel.

Adjustment of valves

Valve adjustment is carried out with the power unit turned off. Before starting work, it is recommended to install transport on a viewing hole.

The first step is to set the piston of cylinder number 1 to top dead center. After installing it, turn the crankshaft 1-1.5 turns clockwise.

After the intake and exhaust valves are closed, you can begin to set the valve clearances on the ZIL-131. To do this, hold the adjusting screw with a screwdriver and loosen the locknut with a wrench.

The gap must not exceed 0.3 mm for both valves.

Then you need to repeat the procedure for the remaining seven cylinders. At the end, you need to start the engine and check the performance of all systems.

Ignition installation

The ignition installation on this ZIL model is carried out as follows:

  1. Set the piston to the top dead center position.
  2. Install the groove so that it is parallel to the housing of the switchgear drives.
  3. Turn the crankshaft by the value of the installation angle.
  4. Remove the plate fixing bolt.
  5. Turn on the ignition and turn the switchgear housing counterclockwise.
  6. Tighten fasteners.
  7. Check the correct installation of wires in accordance with the order of operation of the cylinders.

Oil change

The oil change is carried out with the engine turned off. Before filling, it is necessary to drain the old oil fluid, clean the drain magnet and replace the fine filter.

New oil is poured using a funnel. After refueling, you need to let the engine run for several minutes at medium speed so that the lubrication system is filled. After that, it is recommended to turn off the power unit and check the oil level in the system.


In 1970, on the basis of the ZIL-131 truck, already known by that time, a fuel truck was created by order of the army. Rather, they created a whole series of fuel trucks. Now I will explain - the ATZ-4, ATZ-4.3 and ATZ-4.4 models are essentially the same car. It's all about the tank. When it is steel, it has a capacity of 4000 liters, when the steel was changed to aluminum, due to the thickness of the walls and the overall strength of the structure, the capacity increased to 4300 liters, and when the tank itself was slightly lengthened (this is the only visible difference), the tank already contained 4400 liters. The index changed accordingly.

According to the technical description, this tank was intended for the transportation of filtered fuel and mechanized refueling of tracked and wheeled vehicles. Interestingly, along with the replacement of the base model with 131H in 1986, the chassis for tanks also changed. However, I could not find any information about gas tanks on the 131H chassis. Accordingly, it is impossible to accurately indicate the year of completion of production.

We can only say for sure that in 1994 the ZIL-131N was removed from production, and such gas tanks were also finished with it. What came to replace them - I, alas, do not know ...

The model is the work of the usual Kazan "Elecon". Or rather, not quite usual, but late, the end of the 90s of the last century, when everything went "in disarray" at Elecon - the quality of the castings deteriorated, they began to make skewed suspensions, tires were not always inserted into the disks, and about giant gaps and thick headlight grilles, I'm not talking at all ...



Look at the top view... Of course, I understand that since the hood opens, then there must be some kind of gap there. But for such a... What about a cistern? It's just inhuman horror - if it were a prefabricated model, I would have put putty on it a long time ago and brought everything into a human form, but at 1:43 I rarely do this anywhere ... Authenticity is more expensive :-)


In general, looking at all the distortions and imperfections, I can say that this model is like all those times of the 90s ... Unstable, bursting at the seams, skewed, but still native. So this ZIL will remain for me :-)
As for the name, choose for yourself. I prefer the ATZ-4-131 of the year 1980 :-) Well, something like that, in general ...

The family of various tankers on the ZIL-131 chassis included the simplest dual-use models, as well as the ATZ-4-131 and ATZ-4.4-131 unified military tankers and the MZ-131 oil tanker.

AC-4.0-131- a multi-purpose dual-purpose tank truck on the ZIL-131 chassis with a steel tank with a capacity of 4100 liters and a gravity drain of fuel. Adopted in 1971 and was part of the material support units for the storage, transportation and pumping of petroleum products. It was equipped with a vortex pump SVN-80 with a capacity of 500 l / min driven by a car power take-off, a side control cabin, longitudinal cylindrical canisters or boxes for storing sleeves, a pre-filter and a control system. Gross vehicle weight - 10 365 kg.

AC-4.3-131 (ATsZ-4.3-131)- a dual-purpose refueling truck based on the ZIL-131 chassis with a 4300-liter frame tank made of aluminum alloy and a rear control cabin. Adopted in April 1970 and produced until 1973. It was used for transporting, pumping fuel and simultaneously refueling up to four units of wheeled or tracked vehicles with the measurement of dispensed quantities. A vortex pump SVN-80, a fine filter, two fuel meters-litrometers, pipelines and dispensing hoses with taps, side cases for hoses were mounted on the machine. All operations are controlled manually from the control cabin installed between the driver's cabin and the tanker. Gross weight - 10 510 kg.

ATZ-4,4-131- army tanker on the ZIL-131 chassis with a steel carrier tank with an operational capacity of 4400 liters. Adopted on January 21, 1975. According to the general design and configuration, it was unified with the ATZ-4-131 tanker and served for the simultaneous refueling of four consumers.

AT3-4-131 (ATZ-4.1-131)- a multi-purpose army tanker on the ZIL-131 chassis with a steel tank with a capacity of 4148 liters. Adopted in July 1976 and produced from the same year by the Reutov Construction Equipment Plant. According to the general design and equipment, it was unified with the ATZ-4.4-131 tanker. The curb weight of the car is 7040 kg, the total weight is 10 370 kg.

The three-axle vehicle ZIL-131 is the main model of the off-road truck of the Moscow Likhachev Plant in the period from 1966 to 1994. This is one of the most famous and recognizable cars of the Soviet automobile industry throughout the world. ZIL-131 is a car, first of all, a military one, which for decades has been supplied to the Soviet army and the armed forces of the countries that are allies of the USSR.

Thanks to this prevalence, not only in the socialist states, but also in many, so to speak, "banana republics", ZIL-131, unexpectedly for itself, made a long and successful film career in Hollywood.

In addition to dozens of films about James Bond and other numerous, less well-known, Cold War movie fighters, ZIL-131 has repeatedly appeared in frames of modern foreign cinema.

The Expendables team quickly restored the abandoned ZIL-131: Statham deals with the engine, Stallone provides "wise leadership."

In the same "Transformers", for example. Or in "The Expendables-2": Sylvester Stallone and his "dream-team" from the stars of retro action movies famously burst into the terrorists' lair on a military "ZILka"! At the same time, the creators of all these films - both the old and the new time, during their shooting have never visited not only Russia, but even the CIS.

ZIL-131 is a front-engine all-wheel drive truck with a 6x6 wheel arrangement. Initially, it was created as a cross-country vehicle. For the transport of goods and people, as well as for towing trailers - both on all types of roads and on rough terrain.

In the lineup of the Likhachev Plant, the ZIL-131 replaced the no less famous, and even the legendary off-road car.

In terms of its cross-country ability, the ZIL-131 is not inferior even to tracked vehicles. This truck was created on the basis of the production experience of its predecessor, the ZIL-157. The new ZIL off-road truck has been significantly improved; equipped with an innovative bridge, eight-ply tires with a special tread pattern. At ZIL-131, the front axle was made disconnectable, and one common driveshaft goes to both rear axles from the transfer case.

ZIL-131 proved to be an extremely hardy machine for operation in any climatic conditions, including the Far North, tropical and equatorial latitudes, demonstrating stable and trouble-free operation at air temperatures from -45 to +55 ° C.

Developing the ZIL-131, the designers of the Likhachev Plant successfully coped with the task of creating an off-road army truck, inexpensive to manufacture, easy to operate and most unified with its "civilian counterpart".

The first mass production was nevertheless launched a new mass truck for the national economy -; and three years after that - the army ZIL-131. However, less than five years later, from January 1971, it ceased to be a purely military vehicle and began to be mass-produced as a simplified national economic truck - without the units characteristic of army vehicles.

The serial, “classic” ZIL-131 was produced for twenty years: from 1966 to 1986, when its modernized version, the ZIL-131N, was launched into the series. This version was equipped with an improved engine (improved efficiency, extended working life), more modern optics and an awning made of new synthetic materials.

A few years later, they began to try to equip the ZIL-131N not with carburetor, but with diesel engines: their own ZIL-0550; motors from other manufacturers: D-245.20; YaMZ-236 and even Caterpillar.

However, the modernized 131st was not widely used, despite the fact that, in addition to the Likhachev plant, it was also produced at the Ural Automobile Plant until 2006. It's just that production volumes were far from the same. In the Urals, by the way, ZIL-131N has been produced in recent years under the name Amur-521320.

The maximum level of production of trucks of the 131st series fell on the 80s, when up to 48 thousand such vehicles were produced per year. And the number of workers employed by that time at ZIL reached 120 thousand people. In total, the Likhachev plant built 998,429 cars of the ZIL-131 family. The vast majority of them, of course - in the years of the USSR. And for the entire period of 1987 - 2006, both enterprises assembled 52,349 cars of an updated modification - ZIL-131N.

Special vehicles based on ZIL-131

A significant volume in production was occupied by a universal chassis designed for mounting various superstructures and special equipment. In addition to the well-known fire engines, the following were also produced on the ZIL-131 chassis:

  • Fuel tankers: ATZ-3.4-131, ATZ-4.4-131, ATZ-4-131;
  • Oil tankers: MZ-131;
  • Universal tank trucks: AC-4.0-131, AC-4.3-131.
  • Aerodrome mobile units (tractors): APA-50M; APA-35-2V. It is interesting that these ZIL-131s serving in aviation had a total mass in excess of the officially permitted: 10,950 and 11,370 tons, respectively.

For army versions of workshops, laboratories, mobile radio stations, command and staff vehicles, standard KUNG K-131 and KM-131 van bodies were developed. These KUNGs were equipped with a special filtration unit FVUA-100N-12. It takes air from the surrounding atmosphere and feeds it into the van, while decontaminating it.

In the canisters installed on the sides of the tank, there are three sleeves Du-75 mm 3 m long each. In addition, two Du-38 mm hoses, each 9 m long, are laid in the rear compartment.
To control the amount of liquid in the tank there is a mechanical level indicator.
The electrical equipment system installed on the tank truck allows you to control the limit level of liquid filling with the receipt of light and sound signals, duplication of lamps for emergency overheating of the coolant and emergency oil pressure drop, illumination of the vehicle track and illumination of the control cab.
The tank truck is equipped with a set of spare parts, tools, accessories and fire fighting equipment.
The hydraulic system AC-4.0-131 includes: pump SVN-80; bypass valve; suction, pressure, drain and pumping pipelines; pre-filter; valves and valves. It is operated manually by means of a mechanical transmission.
The pump is attached to the pallet of the control cabin. The operating mode of the pump is changed by a manual gas drive installed in a box on the left side of the tank car. To control the speed of rotation, determine the total operating time of the pump in hours and remotely control the draining of the liquid, the pump is being finalized.
The fittings include standard valves Du-65 mm, Du-50 mm and valves Du-20 mm. Technological piping at AC-4.0-131 is made of steel pipes ø 75x2 mm and 56x2 mm with anti-corrosion coating of their inner surface.
The suction and discharge pipelines are used to fill the tank and dispense liquid from it both with its own pump and with extraneous pumping means. The inlet-outlet pipes of these pipelines are brought to the left side of the tank car. The pre-filter is installed in the sump tank and attached to the suction pipe. The drain pipeline is designed to drain the liquid from the tank by gravity.
At AC-4.0-131, you can perform the following loading and unloading operations:
- filling the tank and draining the liquid from it with your own pump;
- filling the tank and draining the liquid from it with extraneous pumping means;
- pumping liquid, bypassing the tank;
- draining the liquid from the sleeves into the tank and dispensing the liquid from the tank through the dispensing valves.
