PISTON AND PISTON RING
Piston diameter
Measure the piston diameter with a micrometer
at 15 mm of the end of the skirt. If the piston
diameter is lower than the service limit, replace
the piston with a new one.
Tool ref.:
Micrometer (75-100 mm)

Space between the piston ring and the
groove
Measure the side spaces of the 1st and 2nd
piston rings with the thickness gauge. If any of
the spaces exceeds the service limit, replace the
piston and the rings.
