With 48452, the safest match is the specific check-valve sealing location in the drive or bell-housing assembly, because Mercury uses several different quad rings and sealing rings across nearby service areas.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eWhen This Part Needs Replacement\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThis quad ring is typically replaced when the oil release check valve is leaking, hardened, damaged, or when the check-valve assembly is already apart for service. Because 48452 seals the oil release check valve itself, it is usually smarter to renew it during that repair than to reuse an aged seal in the same location. This service guidance is a practical inference based on its documented role in the oil release check valve assembly.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eInstallation Notes\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eInstall 48452 only after confirming the exact Mercury MerCruiser diagram for the drive being serviced.
