General information

KamAZ-43253 is the optimal modification for those companies that need universal transport operating in different fields of activity. Moreover, this version looks more preferable compared to trucks of a higher class, with which the KamAZ-43253 is ready to compete in terms of load capacity and survivability. At the same time, the Russian truck is attractive due to its low operating costs. Among them are relatively low fuel consumption and high power.

Cabin design features

The truck in question is equipped with a licensed Mercedes cabin, which in the basic version does not have a berth. It is mounted on the 4-point air suspension used to equip the Mercedes-Benz Axor.

The cabin, installed on all new products of the Kama Automobile Plant since 2010, has a high level of comfort and can have a high or low roof. The original suspension design has a positive effect on the smoothness of the ride, while at the same time preventing cab sway and reducing vibrations during driving.

The position of the cabin, namely its height, is kept at a constant level, which is not affected by the degree of loading of the vehicle. The driver's seat is also equipped with pneumatics and lateral support.

The position of all seats in the cabin can be adjusted, for which four levels of adjustment are provided. This solution, coupled with the suspension of the cabin itself, provides a high level of comfort.

The steering column tilt and height adjustment function, implemented through pneumatic control, is also convenient for the driver. The steering wheel is equipped with a modern hydraulic booster.

The modernization of the truck cabin also affected its interior decoration. Thus, the quality of the materials used has increased significantly, and the plastic panels have acquired softness and pliability. The instrument panel design has become more modern. and she herself received anti-reflective glass.

The indicators, sensors and screen that are placed on it are informative and easy to read, which allows the operator to read the necessary data about the condition of the car without stopping from driving.

The plastic handles on the cabin doors received new integrated locks, as well as protection in the form of deflectors. There are fairings installed on the sides of the cabin, which are designed to reduce air turbulence and prevent contamination of the rear-view mirrors.

The latter are distinguished by new brackets where the main, curb, sliding and spherical mirrors are mounted, which guarantees the best possible visibility.

The optics of the car have also changed. Headlights, turn signals and side lights now form a single unit, providing excellent visibility and visibility. Three windshield wipers ensure the cleanness of the monolithic windshield.

The new cabin, unlike its predecessor, has a molded plastic (rather than steel) bump stop. The footrests are equipped with special pads that prevent slipping, ensuring safe lifting of the driver and passenger, regardless of weather conditions.

Service

The design of this car, in general, is quite thoughtful. However, some points could have been worked out more carefully. Among the obvious shortcomings that surfaced during operation, it is worth highlighting the following:

1. The control unit fuse often blows - this problem is usually associated with a short circuit and is determined by the classic “ringing” using an ohmmeter.
2. Diagnostic connector pinout required. Attached is a diagram.

1. Not the best location of the accelerator sensor. Nothing can be done here - this is a flaw of the design engineers. Unfortunately, in our auto industry we cannot live without this.

There are other minor complaints against the manufacturers.

Design Features

Compared to its predecessor, KamAZ 43253 has some features. In particular, it is smaller in size. The chassis length is 7,425 mm, and the onboard version is 7,505 mm. Also, this truck, if necessary, is equipped with additional equipment, including such as a cross-axle differential lock and a power take-off for attachments, if any.

There are custom-made modifications that are adapted to difficult and extreme operating conditions: at ambient temperatures from -40 to +50 degrees Celsius, dust levels up to 1.5 g per 1 cubic meter.

Flatbed version and universal chassis

The universal chassis is designed for special vehicles, such as concrete mixers, truck cranes and so on. Often, within urban operating conditions, KamAZ 43253 vehicles are used in fire services and housing and communal services.

Onboard options are also quite common. The side platform has folding sides with a height of 0.73 m as standard. If the customer wishes, they can be increased. The internal dimensions of the onboard platform are 5,162 mm by 2,470 mm. At the same time, the loading height is 1,425 mm.

Cabin KamAZ 43253

All models of this manufacturer are equipped with standard cabins, which are licensed by the German concern Mercedes. They can be with a high or low roof. A sleeping place, as already noted, is not provided. At the same time, the cabin has four mounting points for the air suspension. This is very convenient from a practical and ergonomic point of view.

The driver and passenger seats are conveniently adjustable in four directions (in practice, this turns out to be quite enough); you can also adjust the steering column, both in height and inclination angle. By the way, the steering itself is equipped with an effective and truly “working” power steering.

Design and interior

The cabin uses really high-quality materials to create a feeling of comfort. The developers thought through the location of sensors, control devices, and information boards. All of them are located so as not to distract the driver from driving the vehicle.

The modern look of the truck is given by: a large windshield with three cleaning brushes, a new bumper and an original radiator grille. The hanging elements are usually painted the same color as the cabin.

Car cost

Excellent technical characteristics, low fuel consumption and excellent maintainability made the KamAZ-43253 a very popular truck, which could not but affect its price.

At the end of last year, prices for new station wagons and flatbed cars of this model started at 2.5 and 2.9 million rubles, respectively. On the secondary market, the range of prices for the used cars in question fluctuates greatly. The cost depends on the configuration and condition of the vehicle.

Today, a car of this model can be bought second-hand for 800 thousand rubles, but you need to be very careful not to buy a truck that requires serious repairs of units or components.

Main disadvantages and advantages

If you study specialized forums and chats where KamAZ 43253 is actively discussed, you can highlight important aspects, both positive and negative.

Advantages of the car:

1. Gravity.
2. Small size, which is important in city conditions.
3. Spacious, modern cabin.
4. Maintainability.
5. Affordable price.

Flaws:

1. Low traffic.
2. Sound insulation in the cabin, although present, is clearly insufficient.

Transmission

The 5-speed manual gearbox of the KamAZ-142, which has remote mechanical control and a final drive ratio of 4.98, also gradually became a thing of the past, along with the KamAZ-4325. KamAZ-43253 vehicles are equipped with a 6-speed manual transmission ZF 6S700 with a final drive ratio of 6.53.

It is a six-speed gearbox in which all forward gears are engaged by synchronizers, and the reverse gear is engaged by a gear clutch. The highest gear is overdrive. The maximum torque is 700 N.m. The weight of the ZF 6S700 box is 103 kilograms. The gearbox of this model has proven itself well on delivery trucks operating on intracity routes. Countless stops, maneuvering in tight spaces - such conditions require modern drive technology, which is what the ZF 6S700 is.

Gearbox KamAZ-43253.

Both of these gearbox options - the old and the new - work in conjunction with a single-plate diaphragm, push-type clutch with a hydraulic drive, which is complemented by a pneumatic booster. Currently, KamAZ-43253 is equipped with a ZF&Sashs MF 362 model clutch. The model in the domestic auto industry is quite common: in addition to KamAZ vehicles, such a clutch basket has long been installed on Minsk Auto trucks, MAZ-4570; PAZ/KAVZ buses.

Transmission manufacturer ZF Friedrichshafen AG is one of the leading supplier concerns to the automotive industry. KamAZ also created a joint venture with this company: “ZF-Kama” and established assembly production of manual transmissions in Naberezhnye Chelny.
