Pistons — nominal diameter of 100 mm, with conic dredging on the bottom, with a thermoregulating insert, are cast from an aluminium alloy and covered by tin. In the top part is available three flutes for piston rings.
Piston fingers — floating type in diameter of 25 mm, hollow. For increase of fatigue durability the internal surface of fingers has the improved cleanliness of processing.
Rods — steel, двутаврового sections. The length of a rod is increased by 7 mm in comparison with rods of engines ZMZ-4025, ЗМЗ-4026. Diameters of the top and bottom heads of rods coincide in the sizes with rods of engines ZMZ-4025, ЗМЗ-4026.
The cranked shaft — five-basic, is cast from special high-strength pig-iron and has training of all necks by currents of high frequency.
The forward end of a cranked shaft is condensed with an epiploon 4 (fig. 4.88), working on an external surface of a nave of a pulley.
The back end is condensed with an epiploon 2 (fig. 4.89), diameter working on a special neck 80 mm. The neck is tempered by currents of high frequency.
The axial effort is perceived by a forward support of a cranked shaft through two persistent washers.
Loose leaves radical and шатунных bearings of a cranked shaft are made of the steel tape which have been filled in with an antifrictional alloy.
Flywheel — pig-iron with a steel gear wreath for start-up by a starter; отбалансирован in gathering with cranked shaft and coupling. The flywheel is attached to a cranked shaft (to an end face of a neck in diameter of 80 mm) by seven self-blocked bolts of M 10u1,25 mm.
