Because 864596066 is a calibrated shim\/race rather than a one-size-fits-all bearing part, correct selection is part of the setup process itself. This service guidance is a practical inference based on Mercury’s thickness-coded thrust-bearing race listings.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eInstallation Notes\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eInstall 864596066 only after confirming the correct Mercury service diagram and measuring for the required thrust-bearing stack thickness. Current parts diagrams place it in the same area as the thrust bearing assemblies, thrust collar, upper driveshaft, and clutch components, so race selection and assembly order should be checked carefully during reassembly.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eCurrent sources reviewed show \u003cstrong\u003e864596066\u003c\/strong\u003e as an active OEM Mercury number.
