4.8.4.2. Control of mass of pistons

Install pistons only of one weight group in the engine.

On weight pistons of one engine should not differ from each other more than on 5 g.

If there is no set of pistons of one weight group, it is possible to remove a part of metal from the basis of lugs under a piston finger. Places of removal of metal are specified by shooters in the drawing. Metal removal, however, should not exceed 4,5 mm on depth of rather nominal height of the piston (59,4 mm), and on width with a diameter of 70,5 mm is limited.
