X: Maximum value of standard projection of selected gasket . . . 0.555 (0.0219) (in chart A) + 0.05 (0.0020) = 0.605 (0.0238) 7. Determined 1.20 (0.0472) (Grade 2)*2 *1: If the average value of projections for all pistons is, for example, 0.553 (7) 5, as shown in the table above, it should be rounded off as fol- lows: *2: If X < Y, then the thicker grade 3 gasket must be used.
