Scheme for removing metal from the piston to adjust its weight
The arrows indicate the places where the metal can be removed.
Diameter of pistons of various classes, measured perpendicular to the pin axis at a distance of 52.4 mm from the piston crown, mm:
class A | 75,94 – 75,95 |
class B | 75,95 – 75,96 |
class C | 75,96 – 75,97 |
class D | 75,97 – 75,98 |
class E | 75,98 – 75,99 |
The increase for the repair dimensions of the pistons is 0.4; 0.8 mm.
Pistons of the same engine should not differ in mass by more than 2.5 g. When adjusting the mass, metal removal should not exceed 4.5 mm in depth relative to the nominal piston height (59.4 mm), and in width should be limited to a diameter of 66.5 mm.
When pressing the piston pin into the piston, use tool A.60325 instead of 02.7853.9500.
