Ralph:

When rebabbitting the thick shell "Insert" bearings, they are mounted in the rod with the appropriate shim pack and then poured.

Afterward, reaming gets them to size.

Use some heat to try to loosen the stuck ring.  Most times, if you get the piston smoking hot (no hotter), the rings will pop out on their own.  If not, while still too hot to touch, dip the whole works in your favorite penetrant or solvent and let it cool overnight.  Gentle prying should make it give up.

If you break it - don't worry.  There are folks out there (Otto Gas Engine Company) who can supply single rings or sets in a very large variety of sizes.

Take care - Elden
