Piston Ring Gap
Check the rings in the bore to determine the end gap
clearance.
Position the rings, one at a time, in the cylinder to the
lowest point of ring travel. Use an inverted piston to
place the ring squarely in the bore. With a feeler
gauge, measure the ring end gap.
Using a ring file, open the gap on any ring which does
not meet the minimum gap. Discard any ring which
exceeds the allowable gap.
NOTE: The ring is shown at the top of the bore for
clarity.
