Piston Ring: Testing and Inspection
End Gap
CAUTION: Use care when fitting piston rings to avoid possible damage to the piston ring or the cylinder bore. Piston rings should not be transferred
from one piston to another.
NOTE: Cylinder bore must be within specification for taper and out-of-round to fit piston rings.
1. Use a piston without rings to push a piston ring in a cylinder to the bottom of ring travel.
2. Use a feeler gauge to measure the top piston ring end gap and the second piston ring end gap.
