PULLEYS
Since May, 1983 in engines ONS two types of pulleys of a cranked shaft are used: cast from pig-iron or shaped from a steel. Pulleys differ by means of the signs serving for installation of ignition:
– On steel pulleys adjusting signs cover corners: from 4 ° after ВМТ to 12 ° before ВМТ, and digital designations are located everyone 4 °;
– On pig-iron pulleys adjusting signs cover corners: from 0 ° (ВМТ) to 16 ° before ВМТ and they are hyphens (digital designations are absent); everyone 4 ° the hyphen of a designation is deeper than the next. |
