2) Using a groove cleaning tool, clean the piston ring grooves.
3) Using solvent and a brush, thoroughly clean the piston.
NOTE:
Do not use a wire brush.
2. The standard measurement of the piston outside diameter is taken 14 mm (0.5512 in.) from the bottom of the piston.
3. Calculate the difference between the cylinder bore diameter and the piston diameter.
Piston-to-cylinder clearance
0.03 - 0.0 5mm (0.0012 - 0.0020 in.)
4. Inspect the piston ring side clearance.
Using a feeler gauge, measure the clearance between new piston ring and the wall of the ring groove.
If the clearance is greater than maximum, replace the piston.
5. Inspect piston ring end gap.
To measure the piston ring end gap, insert a piston ring into the cylinder bore. Position the ring at right angles to the cylinder wall by gently
pressing it down with a piston. Measure the gap with a feeler gauge. If the gap exceeds the service limit, replace the piston ring. If the gap is too
large, recheck the cylinder bore diameter against the wear limits. If the bore is over the service limit, the cylinder block must be replaced.
