Piston Ring: Testing and Inspection
1. Check the piston ring for damage, excessive wear, and breakage and replace if defects are evident. If the piston has been replaced with a new one,
the piston rings must also be replaced with new ones.
2. Check for the clearance between the piston ring and ring groove. If the limit is exceeded, replace the ring or piston, or both.
Standard value: 0.03 - 0.07 mm (0.0012 - 0.0028 inch).
Limit: 0.1 mm (0.004 inch).
3. Install the piston ring into the cylinder bore. Force it down with a piston, its crown being in contact with the ring, to correctly position it at right
angles to the cylinder wall. Then, measure the end gap with a feeler gauge. If the ring gap is excessive, replace the piston ring.
