transmission
The 5-speed mechanical gearbox KAMAZ-142, with remote mechanical control and a gear ratio of 4.98, gradually became a thing of the past with the KAMAZ-4325. The Kamaz-43253 is now equipped with the 6S700 transmission with a ratio of 6.53.
This is a six-speed transmission, which contains all front synchronizer gears and a rear gear with a toothed clutch. The highest gear is upshifted. Maximum torque is 700 N.M. The weight of ZF 6S700 gearbox is 103 kg. The gearbox of this model is well-proven on trucks, working on inner-city routes. Countless stops, maneuvering in tight spaces – such conditions require modern drive equipment, which is the ZF 6S700.
Both gearboxes – old and new – in combination with the single diaphragm clutch have a hydraulic drive, which is supplemented by a pneumatic booster. The KAMAZ-43253 is currently equipped with a ZF & Sachs MF 362 clutch. This model is widespread in local automobile industry: in addition to the KAMAZ, this clutch has long been installed on the MINSK truck plant MAZ-4570. Busse Paz/Kavz.
Manufacturer of gearboxes ZF Friedrichshafen AG is one of the leaders in the production of car-like devices. KAMAZ also created a joint venture with this company: ZF-Kama and created a manual transmission module in Naberezhnye Chelny.
KAMAZ 6522 6×6, 13.4 t. (permissible up to 19 tons), S/S
The “6522” was made on the basis of the “6520”. The machine has a pretty decent body volume for the claimed capacity. Due to the full stroke, the truck works well in off-road conditions. At the same time, it is not afraid of low temperatures. One of the reasons for this is that the fuel system is now controlled mechanically, not electronically. Due to this, it is not only easier to put the engine into operation in winter, but also it is easier to repair and service it. And the fuel requirements for the “6522” are not so high any more. The exhaust gases are used for body heating.
The suspension is very complicated. According to drivers, the feeling when fully loaded is that this is the most rigid model under KAMAZ (“…as if there are no shock absorbers at all!”). At speeds over 80 km/h the cabin vibrates a lot (“… my teeth shut off!”). The driver’s seat is too high and uncomfortable. From the inconveniences also can be noted the completely unattractive location of the gear lever and a difficult fixation of the steering column, which, moreover, all of the Belarusian stock, quickly fumbles. But the main disadvantage could be a not too powerful engine for this machine. When fully loaded, the dump truck takes a long time to get and accelerate.
Kamaz-43253 cabin
The trucks of this model are equipped with a standard – KAMAZ (Licatzed Mercedes) cabs without a bed. Both with low and high roof. These are comfortable (especially comparing to the classic Kamazes) cabs on a four-stage air suspension from the Mercedes-Benz Axor truck.
Since the beginning of 2010 all new Kamaz trucks are equipped with it. Air suspension improves ride comfort, reduces vibration and prevents the cab from rocking when driving at speed. It also maintains a constant measure of the cab for continued driving, regardless of the vehicle’s service station.
The combination of the new air suspension of the cab and a comfortable seat (also on a vibration-damping air suspension with side support) has increased comfort to an unprecedented level for KAMAZ. The driver’s and passenger’s seats are equipped with 4-position adjustments.
The steering column is also adjustable. The height and tilt of the steering wheel can be easily adjusted with a pneumatic steering column control. The steering wheel itself is equipped with hydraulic packing.
The quality of the interior trim has been significantly improved. The plastic overlays and the dashboard have become softer and more pleasant. The dashboard has been treated according to modern trends and equipped with an anti-glare coating. Thanks to the properly positioned graphic display, poll pointers and tax levers, the driver can get the necessary information instantly, without distracting from the street.
The door handles have become plastic with built-in locks that are protected from distracting air currents. This keeps the door handles clean, along with the cladding on the sides of the cab. These facings reduce air turbulence and reduce pollution from the current, mirror and doors in general.
Instead of the former metal “Chipper” in the remaining cab, a plastic bumper is installed on the remaining cab. The foot boards on both sides are equipped with anti-slip pads. Climbing into the cab is safe and comfortable in all weathers. The new design of the cab also has a completely new appearance with improved visibility and visibility. Headlights, parking lights and turn signals merged into a single unit.
The rear mirrors have changed the shape of the bracket. The right side has a roll and edge mirror, and spherical mirrors have been added on both sides to cover blind spots. The windshield is fully trimmed with three windshield wipers.
Kamaz 65222 6×6, 19,5 t. (Restyling 65222), S/S
After the restoration in 2010 “65222” was replaced by “65222”. The new modification increased not only due to all-wheel drive, but also due to special primers on profiles, large wheels and single tires. The base became longer, so the body volume could be brought to 16 cubic meters. The interval between trips is increased and fuel consumption is reduced by 10%. As an option in the cabin is installed a sleeping bag.
The cost of the truck is high enough, at the level of “65201”. Dump truck is positioned as a vehicle to work in northern conditions. According to the reviews of drivers with severe frosts, the electrical appliances are not in order. Often there is a factory defect – up to the fact that the fasteners on the frame do not fit the diameter of the bolts. The transmission, air heater, and belly muscles deteriorate quickly. The turn signals don’t work well. Rear feathers are better replaced after a few months. The steps are as high as they were, and still are.
Owner and driver reviews
Reviews of owners and drivers on these trucks are mostly positive. Kamaz-43253 In daily routine work shows itself well as a reliable and dependable machine, which almost never fails. The engine is enough to spare, has good dynamics and good maneuverability in urban conditions. The cabin is convenient, spacious and comfortable for work. But the quality of the sound insulation is not satisfying for everyone. Heat insulation and fast heating of the cabin in winter conditions is up to the mark – it is affected by the upgraded air duct system and a powerful cabin heating.
One should drive it mainly on asphalt. From the street this truck is not able to show a serious cross-country ability. All the information that comes across, mainly concerns only little things that can be easily fixed. The quality of assembly in recent years has become much more decent than before. Due to this and the economy of Kammin diesel, the truck for the first year of operation with a stable load fully pays for itself and begins to benefit.

Design features of the cab
The truck in question is equipped with a licensed Mercedes cab, which in the basic version has no place to sleep. It is mounted on a 4-point air suspension Mercedes-Benz Axor.
The cabin, which is installed on all new trucks of Kamsky automobile plant since 2010, has a high level of comfort and can have a high or low roof. The original design of the suspension positively affects the rest of the travel, and at the same time prevents the cab from rocking and reduces vibration during driving.
The position of the cab, namely its height, is held at a constant level that is not affected by the loading level of the vehicle. The driver’s seat is also equipped with “pneumatics” and side support.
The position of all seats in the cabin can be adjusted, for which there are four levels of adjustment. This solution in combination with the cab suspension itself provides a high degree of comfort.
The pneumatically controlled tilt and height adjustment of the steering column is convenient for the driver. The steering wheel is equipped with a modern hydraulic power unit.
Modernization of the cab also affected the interior. The quality of materials used has increased significantly, plastic panels have become soft and pleasant to the touch. Design of the dashboard became more modern. It received anti-glare glass.
Announcements, gauges and screens attached to them are informative and easy to read, so that the driver can familiarize himself with the necessary data on the state of the car without taking his eyes off the controls.
The plastic handles on the cab doors have new built-in locks and protection in the form of deflectors. Masking elements are installed on the sides of the cab, reducing air turbulence and preventing rear-view mirrors.
The latter are distinguished by new brackets to which the main, curbside, sliding and spherical mirrors are attached, which guarantees the best possible view.
The appearance of the car has also changed. The headlights, “indicators” and “lights” now form a single unit and thus provide excellent visibility and visibility. Three windshield wipers guarantee a clean monolithic windshield.
Unlike its predecessor, the new cab has a stop buffer made of shaped plastic (instead of steel). The running boards are equipped with special pads that prevent slipping and provide safe access to the driver and front passenger, regardless of weather conditions.
The cost of the car
Excellent technical characteristics, low fuel consumption and excellent maintenance have made 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 platform trucks of this model started from 2.5 and 2.9 million rubles. In the second market, the price range of the corresponding used vehicle is very different. The cost depends on the configuration and condition of the car.
