5. Measuring piston diameter
Using a micrometer (2) measure the diameter of the
piston (1) to determine the assembly clearance.
The pistons are selected in two classes A and B ac-
cording to the diameter.
NOTE: The diameter has to be measured at the distance
X from the base of the piston skirt:X = 18 mm (0.709"), for
the F2B engine;X = 19 mm (0.748"), for the F3A engine.
6. As spares they are supplied in class A and can also
be mounted in the cylinder liners with inside diameter
class B.
The clearance between piston and cylinder liner can
also be measured with a feeler gauge (1).
7. Piston pin
The pins are mounted with clearance both on the
small end and on the piston.
Measure the diameter of the pin (1) with a micrometer
(2).
