Built from alloy steel, this bearing is manufactured to meet or exceed the quality of the original equipment part it replaces, giving rebuilders and engine shops a reliable option when servicing the bottom end of these V8 marine engines.\u003c\/p\u003e\u003cp\u003eEach 18-1308 bearing is sized at standard (Std.) tolerance, which is the baseline fit specified before any machining oversize is required. It is compatible with oil lubrication and is supplied as a single rod bearing, making it easy to order the exact quantity needed for a full engine rebuild or a partial bearing replacement job. Because it is a precision wear component, using the correct part number and size is essential to maintaining proper bearing clearance and engine longevity.\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 18-1308\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Rod Bearing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e Standard (Std.)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.14 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Lubricant:\u003c\/strong\u003e Oil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Fitment:\u003c\/strong\u003e MerCruiser 7.4L MIE Gen V and Gen VI 454 cid V8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 23-85701, 23-15961, 23-52221, 23-52270, F3910555, F3916351, FI1100305, FI1100570\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMerCruiser 7.4L MIE GEN V, 454 cid, 8 cylinder, 4 stroke, 1992-1995\u003c\/li\u003e\n\u003cli\u003eMerCruiser 7.4L MIE GEN V, 454 cid, 8 cylinder, 4 stroke, 1992-1996\u003c\/li\u003e\n\u003cli\u003eMerCruiser 7.4L MIE GEN VI, 454 cid, 8 cylinder, 4 stroke, 1996-1997\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e23-85701\u003c\/li\u003e\n\u003cli\u003e23-15961\u003c\/li\u003e\n\u003cli\u003e23-52221\u003c\/li\u003e\n\u003cli\u003e23-52270\u003c\/li\u003e\n\u003cli\u003eF3910555\u003c\/li\u003e\n\u003cli\u003eF3916351\u003c\/li\u003e\n\u003cli\u003eFI1100305\u003c\/li\u003e\n\u003cli\u003eFI1100570\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-1308 rod bearing fit?\u003c\/strong\u003e The Sierra 18-1308 is designed for MerCruiser 7.4L MIE Gen V and Gen VI 454 cid V8 marine engines, covering 1992-1995, 1992-1996, and 1996-1997 production.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-1308 a standard size or an oversize bearing?\u003c\/strong\u003e It is a standard (Std.) size rod bearing, meaning no machining oversize is required for installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich OEM part numbers does the 18-1308 cross-reference to?\u003c\/strong\u003e The 18-1308 replaces OEM numbers 23-85701, 23-15961, 23-52221, 23-52270, F3910555, F3916351, FI1100305, and FI1100570.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-1308 rod bearing made from?\u003c\/strong\u003e This bearing is made from alloy steel, matching the material used in the original equipment rod bearing it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many bearings come in one 18-1308 unit?\u003c\/strong\u003e Each 18-1308 is sold as a single rod bearing, so the quantity needed depends on how many bearings the engine rebuild requires.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Sierra 18-1308?\u003c\/strong\u003e The 18-1308 measures 0.39 x 0.39 x 0.39 inches and weighs 0.14 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-1308 meet original equipment quality standards?\u003c\/strong\u003e Yes, the Sierra 18-1308 rod bearing is manufactured to meet or exceed the quality of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat lubricant should be used with the 18-1308 bearing?\u003c\/strong\u003e The 18-1308 rod bearing is designed for use with oil lubrication, as is standard for connecting rod bearings in these engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 18-1308 be used for a full engine rebuild?\u003c\/strong\u003e Yes, the 18-1308 is part of a complete engine bearing lineup and can be ordered in the quantity needed for a full rod bearing replacement during an engine rebuild.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between the 18-1308 and an oversize bearing like the 18-1309?\u003c\/strong\u003e The 18-1308 is the standard size bearing, while other part numbers in the same lineup are machined to specific oversizes for engines that have had their crankshaft journals reground;
