Piston Diameter Measurement

Measure the outside diameter of the piston 17 mm [A]
up from the bottom of the piston at a right angle to the
direction of the piston pin.
If the measurement is under the service limit, replace the
piston.

Piston/Cylinder Clearance Inspection

The piston-to-cylinder clearance is measured whenever a
piston or cylinder is replaced with a new one. The standard
piston-to-cylinder clearance must be adhered to whenever
the cylinder is replaced.
If only a piston is replaced, the clearance may exceed the
standard slightly. But it must not be less than the minimum,
in order to avoid piston seizure.
(1.9070 ∼ 1.9076 in.)
