HELPFUL TIPS FOR RING FITTING AND SEATING
All pistons (including new ones) should be checked for proper ring to groove clearances.
Ring to piston groove back clearance should be a MINIMUM of .005" deeper than radial wall dimension of piston ring. If piston ring sticks out of groove by any amount, you have the wrong rings (see fig.1).
Ring to groove side clearance should be a minimum of .0015 to a maximum of .003" (see fig.1).
