3.9.8. The control of weight of pistons

The scheme of removal of metal from the piston for adjustment of its weight

Arrows specify places on which it is possible to delete metal.

On weight pistons of one engine should not differ from each other more, than
On ±2,5

If there is no complete set of pistons of one weight group, it is possible to remove a part of metal on the basis of lugs under a piston finger. I will eat metal, however, should not exceed 4,5 mm on depth concerning nominal height of the piston (59,40 mm), and on width 66,5 mm are limited in diameter.
