1. Piston dome
2. Piston measurement
NOTE:
The measured dimension must not be less
than 0.12 mm (.005 in) of the one scribed on piston
dome. Otherwise, use a new piston and measure
piston/cylinder wall clearance following method
with a new piston.
If piston is within specifications, adjust and lock
the micrometer to the obtained piston dimension.
