Piston compression ring
A piston compression ring for sealing cylinder pressure, cataloged under PN 41-0092 in the cylinder and crankshaft section.
This is a piston compression ring, listed in the catalog under part number 41-0092, appearing in the CYLINDER AND CRANKSHAFT section of the parts books. Compression rings ride in the top grooves of the piston and do the job of sealing the combustion chamber against the cylinder wall, keeping cylinder pressure where it belongs during the power stroke instead of leaking past into the crankcase.

Our records show this part turning up across catalog entries from 1969 to 1970, but we don't have anything beyond that pinning it to a specific model or engine size. If you're rebuilding a top end and need to match ring sizing to your bore, give us a call and we'll confirm fitment before you order.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
