MAZ 545 / 545A

In 1969, KZKT made two prototypes – a semi tractor MAZ 545 and ballast tractor MAZ-545A. Both were based on a chassis of MAZ 537. Later, in 1973, they got a new 4-door 8-seats cabin.

In the mid 1970s an updated cabin was presented with additional protection and a flat front mask.

The main technical feature of MAZ 545 trucks was a new multifuel V-38 V12 turbocharged engine rated at 650 hp. It replaced the old D-12A diesel. The second feature was a new 4-speed gearbox.

The tractor version used to work as a part of a combination with GCVW up to 90,8 tonnes and was very similar to MAZ 537G. The 15-tonnes ballast tractor MAZ 545A came fitted with a flatbed body from MAZ 537A and used to tow 75-tonnes trailer systems. Both version had the same curb weight – 22 tonnes. Maximum speed – 65 kph.

After hard factory tests in Syberia and Middle Asia, the test report was mentioned “The trucks showed a satisfactory performance and is generally consistent with the technical specifications”. MAZ 545 characteristics were very close to MAZ 537.
