It secures the bellows boot around the shift cable where it passes through the bell housing, keeping the seal tight against water intrusion at the connection point. This clamp is sold as a package of 5, giving you enough on hand to complete a full clamp replacement or keep spares for future service without having to reorder mid-job.\u003c\/p\u003e\u003cp\u003eBuilt in stainless steel, the clamp resists corrosion in the marine environment where it is installed, holding up to constant exposure to moisture, salt spray, and engine bay heat. It is a direct cross-reference match for the OEM numbers 54-38863, 54-866507, and 54-8M0090424, so it installs the same way and performs the same sealing function as those original clamps.\u003c\/p\u003e\u003cp\u003eThis is a small, low-cost, frequently replaced part: bellows clamps age, lose tension, or corrode over time, and a loose or failed clamp can let water past the bellows seal. Replacing the clamp along with the bellows itself, or on its own if only the clamp has failed, is a straightforward maintenance step for anyone servicing a shift cable assembly.\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 18-7321-9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282165802\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Bellows clamp for the Sierra 18-7321 shift cable assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eSized for the bellows on the Sierra 18-7321 shift cable assembly.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e54-38863\u003c\/li\u003e\n\u003cli\u003e54-866507\u003c\/li\u003e\n\u003cli\u003e54-8M0090424\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-7321-9 bellows clamp fit?\u003c\/strong\u003e The 18-7321-9 clamp is sized for the bellows boot on the Sierra 18-7321 shift cable assembly, where the cable passes through the bell housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many clamps come in a package?\u003c\/strong\u003e The Sierra 18-7321-9 is sold as a package of 5 clamps, not a single unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-7321-9 clamp a direct replacement for OEM clamps?\u003c\/strong\u003e Yes, it cross-references directly to OEM numbers 54-38863, 54-866507, and 54-8M0090424, so it fits and seals the same way as those originals.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-7321-9 bellows clamp made from?\u003c\/strong\u003e It is made of stainless steel, chosen for corrosion resistance in the marine environment where the shift cable bellows is installed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-7321-9 clamp weigh?\u003c\/strong\u003e Each package of the Sierra 18-7321-9 bellows clamps weighs 0.03 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should I replace the bellows clamp on a shift cable assembly?\u003c\/strong\u003e Replace the clamp on the 18-7321 shift cable assembly if it has lost tension, corroded, or if the bellows boot it secures is being replaced, since a loose clamp can allow water past the seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use the 18-7321-9 clamp with a different shift cable assembly?\u003c\/strong\u003e The 18-7321-9 is designed for the Sierra 18-7321 shift cable assembly bellows; check that any other assembly uses a compatible bellows size before substituting.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need any tools to install the 18-7321-9 bellows clamp?\u003c\/strong\u003e Standard hand tools such as a screwdriver or clamp driver are typically used to tighten this style of bellows clamp around the boot; no specialty tools are required.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the 18-7321-9?\u003c\/strong\u003e You receive a package of 5 Sierra 18-7321-9 stainless steel bellows clamps; the shift cable assembly and bellows boot are not included.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-7321-9 genuine OEM or aftermarket?\u003c\/strong\u003e It is a Sierra-branded part manufactured to replace and cross-reference OEM clamps 54-38863, 54-866507, and 54-8M0090424 directly.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988383477979,"sku":"SIE-18-7321-9","price":10.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-7321-9__58612.1737827713.500.750.jpg?v=1785329151","url":"https:\/\/www.goodvibesmarina.com\/products\/bellows-clamp-for-mercruiser-bellows-replaces-54-38863-package-of-5-sierra-18-7321-9","provider":"Good Vibes Marina","version":"1.0","type":"link"}
