( 16 votes, average: 3.19 out of 5)

The bus with the model name PAZ 3205 was put into serial production in 1989 and was modified several times during this period. The model belongs to the class of small high-floor buses, which is well suited for transporting small groups of people over short distances. PAZ 3205 is considered the base model of the Pavlovsk Automobile Plant, although its technical characteristics are similar to later series of vehicles.

The appearance of the bus speaks of its compactness. Its dimensions are 6925 mm in length, 2500 mm in width, 2950 in height. The ground clearance of the bus is 264 mm, which allows you to comfortably drive over small off-road conditions. The total actual weight of the bus is 8060 kg.

Specifications

PAZ 3205 is equipped with one automatic door and a pneumatic brake system. Some bus modifications have two automatic doors, which are controlled from the driver's instrument panel. The nominal capacity of the bus interior is 41 people, based on 5 people per square meter of area. The number of seats ranges from 21 to 25. All of them are covered with leatherette, which is characterized by a long service life.

Where is the engine number GAZ 66?

Look from above in the area of ​​the clutch housing there is a platform for the number. On older versions it’s there, but on the side on the starter side.

why do you need it now? On April 3, a new order of the Ministry of Internal Affairs on car registration came into force. — When registering a car, the engine number will not be checked. So, drivers of older cars will no longer have to worry about the engine number being erased, dirty or impossible to find.

above the crankshaft pulley it seems

now they will send you everywhere to look... whether on ZILs or GAZs, the engine serial number is stamped on a special platform located on the upper end of the cylinder block, in the front right side. See the number on the block, under the compressor mounting bracket.

PAZ 3205 is equipped with different types of domestic and foreign gasoline engines. The new modifications achieve fuel savings of 2-3 liters per 100 km. The total fuel consumption of new modifications of the bus is 18 liters if the equipment operates in a mixed cycle. In the urban cycle, consumption is 20.5 liters. The capacity of the standard fuel tank is enough for a trip of 500 kilometers without the need for intermediate refueling.

The bus has a pneumatic braking system. Some modifications are marked by the presence of a pneumatic-hydraulic braking system equipped with dual-circuit ABS. The PAZ 3205 is controlled by the MAZ 64229 steering system with a standard hydraulic booster. At the same time, a fully loaded bus can reach a speed of 100-120 kilometers per hour.

Story

It was developed by creating dozens of prototypes over almost 15 years. The basis was the one developed in 1972-1977. and the PAZ-3203 bus, prepared for serial production since 1979, but never put into production[1]. The first pilot batch of buses for testing was manufactured in 1979, and assembly line assembly began in 1984[2]. The final version of the bus was approved in 1986. Mass production began on December 1, 1989, when the assembly line completely stopped production of the previous PAZ-672M model. On June 4, 2001, the plant celebrated the production of the 100,000th bus of this model. In 2008, production was modernized, which made it possible to carry out certification for regular use on busy routes, the service life of the body increased significantly (from 5 to 10 years), a more efficient heater and more comfortable seats were installed in the cabin.[3] In 2014, production of the restyled version began [4].

All seats are equipped with special seat belts, and the bus also has luggage racks for backpacks. An additional step at the front door will help even the smallest passengers climb onto the bus. Special devices prevent movement when the doors are open and limit the speed to no more than 60 km/h. All buses for transporting children are equipped with electrically heated rear-view mirrors and a sound signal when reversing.

The buses are equipped with a digital tachograph with a CIPF unit and a Granit-Navigator 2.07 user terminal.

Northern version: double glazing of side windows and insulation of the passenger compartment.

A bus with a diesel engine is equipped with an engine brake as standard.

Interior layout:

• with MMZ engine – 18 months or 50 thousand kilometers
• with ZMZ engine – 24 months or 60 thousand km
