Pistons
Pistons are made of an easy alloy, without flutes on a spending part, with filled in инварным a ring limiting thermal changes of the sizes. In the top part there are three flutes for piston rings. The axis of an aperture of a piston finger is displaced concerning a piston axis. Pistons are delivered in complete sets together with fingers and rods.
Installation method: the arrow at the bottom of the piston should be directed towards a forward part of the engine (towards a system drive газораспределения).
