The thrust bearing is a gearcase component that manages axial load on the propeller shaft, helping the lower unit run smoothly and protecting the gearcase from premature wear. Sierra manufactures this bearing to OEM specification, making it a direct equivalent for the original part rather than a generalized substitute.\u003c\/p\u003e\u003cp\u003eThis is a compact, precision component measuring 0.75 x 4 x 5.12 inches and weighing 0.03 pounds, sized to fit into the Johnson\/Evinrude gearcase exactly as the original bearing does. It is compatible with grease lubrication, consistent with standard outboard gearcase service practice. Because it is held to OEM specification, installation follows the same procedure as replacing the factory thrust bearing, with no modification required.\u003c\/p\u003e\u003cp\u003eThe Sierra 18-1368 is intended for outboard owners and marine technicians performing gearcase rebuilds or replacing a worn or damaged thrust bearing on Johnson\/Evinrude outboard motors. It cross-references directly to GLM 16370 and OMC\/Evinrude\/Johnson 398901, so buyers can confirm fit against the original part number before ordering.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-1368\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Type:\u003c\/strong\u003e Thrust Bearing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Thrust Bearing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Met:\u003c\/strong\u003e OEM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Lubricant:\u003c\/strong\u003e Grease\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions (L x W x H):\u003c\/strong\u003e 0.75 x 4 x 5.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross-Reference:\u003c\/strong\u003e GLM 16370, OMC 398901\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJohnson\/Evinrude outboard motors\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGLM 16370\u003c\/li\u003e\n\u003cli\u003eOMC 398901\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-1368 thrust bearing fit?\u003c\/strong\u003e The Sierra 18-1368 is designed for Johnson\/Evinrude outboard motors as a gearcase thrust bearing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-1368 the same as OMC 398901?\u003c\/strong\u003e Yes, the Sierra 18-1368 cross-references directly to OMC\/Evinrude\/Johnson 398901, so it is a direct equivalent for that original part number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-1368 cross-reference to a GLM part number?\u003c\/strong\u003e It does, the Sierra 18-1368 is interchangeable with GLM 16370.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Sierra 18-1368 thrust bearing?\u003c\/strong\u003e It measures 0.75 x 4 x 5.12 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-1368 thrust bearing weigh?\u003c\/strong\u003e The Sierra 18-1368 weighs 0.03 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-1368 built to OEM specification?\u003c\/strong\u003e Yes, Sierra manufactures the 18-1368 thrust bearing to meet or exceed original equipment quality.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat lubricant should be used with the Sierra 18-1368?\u003c\/strong\u003e The Sierra 18-1368 thrust bearing is compatible with grease lubrication.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when ordering the Sierra 18-1368?\u003c\/strong\u003e The package includes one thrust bearing, part number 18-1368.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or aftermarket?\u003c\/strong\u003e The 18-1368 is a genuine Sierra-manufactured thrust bearing, produced to OEM specification for Johnson\/Evinrude outboard motors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen would I need to replace this thrust bearing?\u003c\/strong\u003e A gearcase thrust bearing like the Sierra 18-1368 is typically replaced during a lower unit rebuild or when the original bearing is worn or damaged.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988087648475,"sku":"SIE-18-1368","price":15.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-1368_lg__37726.1558122245.500.750.jpg?v=1785188702","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-1368-driveshaft-thrust-bearing-for-johnson-evinrude-outboards-replaces-omc-398901","provider":"Good Vibes Marina","version":"1.0","type":"link"}
