Ural » 4320

Constantly working on the improvement of the Ural 375D, engineers of the factory made the original design safer and more durable. The only major drawback was the engine running on high-octane gasoline. Ural started development of the own diesel engine in the 1960s with few prototypes were made. The decision came in 1969, when the government decided to build an engine factory in Naberezhnye Chelny to produce engines for KamAZ and Ural trucks.

The prototypes of the diesel engine YAMZ-740 were finished by 1972 and after hard tests were recommended to mass production for Ural 4320 trucks. The first Ural 4320 truck left the factory on the November 17th, 1977. The engine got designation KamAZ-740.10. This was the V8 powerplant with an output of 210 hp. In 1993, huge fire destroyed the engine factory, so Ural had to change the choice of engines. Since 1993-94 there was YAMZ 236 and YAMZ 238 under the hood of the 4320. The versions with YAMZ 236 engine had a regular hood, while the versions with YAMZ 238 — a longer hood. Since the mid-2000s, all trucks got the long hood.

The engine is connected with a 5-speed manual gearbox KAMAZ 141 and 2-speed transfer case. There is a winch under the front bumper. Top speed — 85 kph. Range — 800 km. Curb weight — 8440 kg. GVW — 13425 kg.

Early Ural 4320 were fitted with an all-metal cargo platform (similar to Ural 375D). In 1986, they got an updated platform with flat floor (version Ural 4320-01). The model was also available as a chassis for special equipment. In the mid 2000-s Ural 4320 got modern Euro-4 engines YAMZ 6565 230 hp (version Ural 4320-61) and YAMZ 536 285 hp (version Ural 4320-73).
