Piston Ring Free End Gap and Piston Ring End Gap

Measure the piston ring free end gap using vernier
calipers. Next, fit the piston ring squarely into the
cylinder and measure the piston ring end gap using the
thickness gauge. If any of the measurements exceed the
service limit, replace the piston ring with a new one.

Piston Pin and Pin Bore

Measure the piston pin bore inside diameter using the
small bore gauge. If either is out of specification or the
difference between these measurements surpass limits,
replace the piston.

Measure the piston pin outside diameter at three
positions using the micrometer. If any of the
measurements are out of specification, replace the
piston pin.
