Piston Ring: Description and Operation
DESCRIPTION
The piston rings include a moly-filled top ring with a symmetric barrel face. The intermediate piston ring is of the standard chrome design OR
Micro-Napier design. The Micro-Napier design has a reduced "hook" on the running face, removes the need for chroming and improves oil economy.
The oil control package consists of two steel rails and an expander spacer.
