Piston Ring Installed Gap

1. Place each piston ring inside cylinder using piston

to push ring squarely into place as shown at right.

2. Measure installed gap with a feeler gauge at both

the top and bottom of the cylinder. NOTE: A

difference in end gap indicates cylinder taper. The

cylinder should be measured for excessive taper

and out of round.

3. If the bottom installed gap measurement exceeds

the service 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 re-

move residue and prevent rust.
