Modifications

The KAMAZ 55102 truck is a more modern representative of the Kama Automobile Plant family of vehicles. The model is capable of taking on board up to 10 tons of various types of cargo. There are two modifications of KAMAZ 55102 in the production line:

• 55102-053 – model with a body with extension sides. The design provides for doubling the volume of the platform.
• 55102-050 – a vehicle with a body with main sides.

Model 55102-053 is capable of transporting more cargo. Both modifications have found application in the manufacturing, agricultural and construction sectors. The technical characteristics of the KamAZ 55102 dump truck make cargo transportation extremely profitable for specialized enterprises, since the vehicle is ready to work in different climatic conditions, regardless of weather conditions.

Malfunctions

Premature wear of the vehicle system can occur as a result of frequent off-road driving. Long-term loads on the engine, steering, and brakes lead to their rapid wear.

The car is distinguished by the installed lighting system. Replacing optics is important if there is a failure in the backlight system.

Signs of steering problems:

• liquid leaks;
• the appearance of a roll when making a turn;
• knocking sounds from the suspension.

Also, KamAZ-55102 must be sent for diagnostics if difficulty rotating the steering wheel begins to be noted. As a rule, all this indicates a breakdown of the rack or related operating mechanisms.

The drive needs diagnostics if the clutch fails to function. The cable may have broken and the cuffs may have been damaged. If there is severe wear, the mechanism must be replaced. Among the signs that there is a clutch failure, it is worth highlighting weak power delivery, acceleration, as well as difficult changes in speed modes. In this case, it is necessary to check the filter elements; if they become clogged, similar symptoms are observed.

Difficulty changing gears or gears not being engaged - these are the main signs of a gearbox failure. In some cases, drive adjustment and synchronizer replacement are required. An unresolved malfunction related to the engine or transmission system will cause an emergency situation on the road. The danger is oil leakage from the side of the box.

Malfunctions with the brake system of KamAZ-55102 can be expressed as follows:

• the car moves to the side when slowing down;
• tight or too soft brake pedal;
• the appearance of extraneous knocks during deceleration.

After any damage to the mechanisms of the automotive system, it is advisable to replace the deformed part with a similar one. The lifespan depends on how regularly the owner undergoes technical inspection.

Engine

Equipped with a four-stroke eight-cylinder power unit, the vehicle has virtually no equal in regional transportation. The engine is distinguished by the presence of turbocharging and an air cooling system. The sleeves are made of high quality cast iron. The cast engine block is also made from cast iron.

Fuel consumption depends on the technical characteristics of the vehicle, as well as the load and some other parameters, including the speed limit. Fuel consumption at a speed of 60 km/h is 24 liters per 100 km.

If you have a trailer, this figure increases to 35 l/100 km. When traveling at a speed of 80 km/h, fuel consumption per hundred kilometers will be 31 and 47 liters without a trailer and with it, respectively.

The technical characteristics of the 1992 KamAZ 55102 are still relevant today, thanks to which the truck continues to actively compete with many modern imported dump trucks.
