Specs At A Glance

Good To Know

Q: Do I need to split the cases to install these seals? A: On most Ovation 340 engines the crank seals sit behind the cases and require case splitting to replace, so plan for a full bottom-end service. Q: How often should crank seals be replaced? A: Seals typically get replaced during a rebuild or when a leak is detected through a pressure test, not on a fixed interval.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
