2. Measure the gap with a feeler gauge at both the top and
bottom of the cylinder.
NOTE: Measure at two points in the cylinder. A
difference in end gap indicates cylinder wear. The
cylinder should be measured for excessive taper
and out of round.
3. If the installed gap measurement exceeds the limit, replace
the rings.
NOTE: Always check piston ring installed gap after
re-boring a cylinder or when installing new rings. A
re-bored cylinder should always be scrubbed
thoroughly with hot soapy water, rinsed, and dried
completely. Wipe cylinder bore with an oil rag
immediately to remove residue and prevent rust.
