When purchasing spare parts, you should take into account the modification of your vehicle.

Suspension, chassis

Three-leaf parabolic springs were installed in the front of this truck, and a half spring with cushions was installed in the rear. A high-quality rear axle is single-stage, equipped with a hypoid gear, characterized by low noise, durability and ease of any maintenance work. The power line of the Mercedes-Benz 814 truck can be equipped with different sets of gear ratios, which ensures consistent efficiency in all transport tasks.

Ease of movement and stability are achieved by installing parabolic springs and maintenance-free hinges with a pre-stressed elastic rubber unit.

Depending on the type, modification and superstructure option, Mercedes Benz 814 trucks were equipped with different types of brake systems: front disc brakes, rear drum brakes. or all disc brakes. However, in any case - with an anti-lock braking system (ABS). The braking system operates on a dual circuit, which maintains a pressure of 10 bar. This ensures a shorter braking distance for the Mercedes-Benz 814 and increased driving safety.

Cabin Mercedes-Benz 814

The cabin of the Mercedes-Benz 814 can comfortably accommodate three people, but in some modifications there are only two seats: a driver and one passenger. Also, in some cab options there is a berth behind the seats. The inside of the cabin is quite spacious and comfortable, and the precise and carefully thought-out arrangement of all truck controls allows the driver to feel comfortable. The ceiling is usually low or high. The floor in the cabin is flat.

Electronic systems are practically not used in controlling this machine, so its operation is extremely simple. The steering mechanism has a two-spoke, fairly large steering wheel, and a hydraulic booster. Ergonomic, strict and laconic old-fashioned dashboard; The sprung seat is simple but quite comfortable.

The level of vibration and noise insulation of the cabin is quite good. But in many regions of Russia it is simply impossible to do without additional heating in winter. Because the cockpit glass area is very large.

Salon

Visually, the interior of the car is disappointing, but it is worth remembering the years of manufacture. People will sit on simple fabric seats with headrests, of which there are three in the Mercedes 814 interior. Popular models are not equipped with a sleeping place, but you can find such versions. There is enough free space in the cabin, plus a completely flat floor.

The control unit is a 2-spoke steering wheel, the rack of which is supplemented with a hydraulic booster. The tidy is unusual, yes, everyone is used to analog sensors, but the design itself is not the same as that of modern cars. On the left, a lever responsible for the parking brake is inserted into the dashboard of the 814.

Visually it seems that it all shakes and creaks on bumps, but the build quality is excellent. Mercedes has always done everything conscientiously, especially in older cars, so you won’t hear any squeaks here. Of course, after so many years the fastenings have weakened.

Exterior of Mercedes 814

There is no point in discussing the visual part, everyone has seen it and it has nothing to stand out on the roads. The shape of the van is interesting due to the short hood. Rectangular optics with halogen headlights are installed, rounded by a radiator grille. The car's bumper is also made of black plastic, which is also used to widen the wheel arches.

The muzzle sports a huge windshield, which provides high visibility and, as a consequence, safety. Two wipers are enough to clean the forehead. The edges of the black grille are complemented by gills. Many people don’t know what they are needed for, let us explain – to blow dirt off the doors with a stream of air.

The sidewall of the Mercedes-Benz 814 is simple, like the entire design. Access to the salon is provided directly through a massive step. Three rear-view mirrors are installed, as many of them are needed to get rid of blind spots.

Reviews of Mercedes-Benz 814 cars

Almost all drivers and owners speak very positively about the Mercedes-Benz 814, as very good, extremely reliable cars. These are real “workhorses” that serve faithfully for many years. And they are very economical in maintenance compared to more modern models. Spare parts, of course, are a bit expensive (as is traditional for any Mercedes model).

On the Mercedes 814 (like its descendant), standard mounting holes are drilled in increments of five centimeters, making the process of reinstalling attachments and/or additional equipment quick and low-cost. This car does not pretend to be any kind of sophistication; its appearance is no longer presentable (considering the venerable age of any specimen). Still, even the newest of them were released back in 1998.

However, with careful operation and proper care, the Mercedes-Benz 814 works out its service life much beyond what can be imagined in the most optimistic forecast.

The machine is absolutely not picky about the quality of diesel fuel; it also “eats” ordinary tractor fuel of poor quality. Therefore, if by chance there is no “branded” gas station on the road, then you don’t have to be afraid to fill up what is available. Even if you are completely unlucky with diesel fuel, you can simply replace the fuel filter and hit the road. Of course, in winter - this is a completely different topic; you need to be more careful with diesel fuel in cold weather.

According to the passport, the vehicle’s carrying capacity is 3,900 kilograms, however, according to the old Russian tradition, during all the years of operation it is possible to transport it according to the norm only a few times. Much more often in fact there is an overload - 5 tons; 5.5 tons; 6 tons; 6.5 tons. Although the last two values ​​are, of course, already violence for the truck, it drives and delivers its entire overload without any particular problems. On the country road it goes extremely smoothly. Diesel fuel consumption is within 15 liters per 100 kilometers.

In cold weather, if the glow plugs in the engine are working properly, then the car starts with half a turn even in twenty-degree frost. The suspension of the Mercedes-Benz 814 is also very, very patient. The main thing is to monitor its condition and not neglect the rule of doing maintenance on time.

Of great importance, of course, is the technical condition in which a particular car was purchased. After all, for some time now we are no longer talking about “second hands” and “cars from Europe”, but about “third or fourth hands”, and cars that have already worked hard on the imperfect roads of Russia or the CIS.
