Modifications

On the basis of the tractor in question, a record number of modifications of "SuperMAZ" was produced.

Version MAZ 54323 with a wheel formula 4 * 2 received a diesel engine with a turbine boost YAMZ-238B. V-shaped engine is equipped with 8 cylinders (working volume - 14 865 cubic cm, power - 330 horsepower, speed - 2 thousand / min.). Starting the motor is facilitated by an electric flare device. There is a dry filter element with a weakening controller and a multimode speed controller. It pumps up the low-pressure fuel pump.

The tractor is equipped with a double-disk clutch with a mechanical drive, springs of a peripheral type and an air booster. MAZ-54323 has 4 stages, demultiplikator, 8 front and 2 rear speeds. The gearshift is carried out by means of a telescopic drive, mounted in the gearbox. An important function of the transmission is the rear axle with diskless wheels.

The spring suspension with longitudinal semi-ellipses is equipped with front and rear shock absorbers for truck stability. Drum brakes interact with a two-circuit pneumatic drive. Behind the camera there are spring-type energy accumulators. The parking brake is a design with an air retarder for the power unit, and a special fuse prevents the condensate from freezing.

Other Modifications

Among other variants of the version in question are the following modifications:

• MAZ-543205. Major updates affected the fifth wheel coupling (its height began to vary from 1.29 to 1.4 m) and the power unit (it began to correspond to Euro 2). The fuel consumption per 100 km has changed slightly. In the updated model, it was 31 liters at a speed of 60-80 km / h .;
• The experimental series 543208 is a variant with an improved YaMZ engine, 400 horsepower;

Features

The car MAZ-54323 is equipped with two types of signals:

1. The pneumatic horn is placed on the roof of the cabin, controlled by a button on the switch on the right under the steering wheel. After the activation of the electric valve, the compressed air enters the signal, after which the high- and low-frequency horn produces a loud sound.
2. Electrical alarm consists of high and low tones. It is activated by means of the handle on the steering column controller.

Also in the alarm system, a noise relay is involved, reporting a reduction in pressure and clogging of the oil and air filters. All the nuances of the device can be seen on the diagram of the installation of the air signal and its electric understudy.

It is worth noting that the MAZ-54323 circuitry for all modifications is standard, at 254 volts. The complete unit of the tractor is available for study in the operating and repair manual.
