When an impeller wears out or loses flexibility, the whole wet end of the pump needs fresh sealing hardware along with the new impeller to restore proper pressure and prevent leaks, and this kit brings everything needed for that job together in one package. It includes a replacement impeller, impeller lubricant to ease installation and protect the vanes on startup, two O-rings, three gaskets, four brass flat head screws, and two stainless flat head screws. Using the lubricant during assembly helps prevent the impeller vanes from tearing or taking a set before the pump is first run. Because the kit bundles both the wear part (impeller) and all the sealing and fastening hardware disturbed during a service job, it lets an owner complete a full pump service in one pass instead of ordering pieces separately. This kit is intended for Johnson Pump F4B-8\/9 pumps used in marine plumbing and washdown applications. Keeping a spare kit on hand is a common practice for boat owners who want to avoid downtime from a worn impeller mid-season.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Johnson Pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 09-45587\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Pump Series:\u003c\/strong\u003e F4B-8\/9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Includes:\u003c\/strong\u003e Impeller, Impeller Lubricant, O-Ring (Qty 2), Gasket (Qty 3), Brass Flat Head Screw (Qty 4), Stainless Flat Head Screw (Qty 2)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e No Color\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 7330717002480\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat pumps does the Johnson Pump 09-45587 kit fit?\u003c\/strong\u003e The 09-45587 kit is designed for Johnson Pump F4B-8\/9 pumps and is not a universal fit for other pump series.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the 09-45587 service kit?\u003c\/strong\u003e The kit includes one impeller, impeller lubricant, two O-rings, three gaskets, four brass flat head screws, and two stainless flat head screws, covering everything needed for a full service of an F4B-8\/9 pump.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need anything else to complete the service, or is this a full kit?\u003c\/strong\u003e This is a complete kit for the F4B-8\/9 pump, bundling the impeller with all the O-rings, gaskets, and screws typically replaced during a service, so no separate hardware purchase is needed for a standard rebuild.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs impeller lubricant necessary during installation?\u003c\/strong\u003e Yes, the included impeller lubricant should be used when fitting the new impeller from the 09-45587 kit to ease installation and protect the vanes from damage on the first startup.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the kit made from?\u003c\/strong\u003e The components in the Johnson Pump 09-45587 kit are made of plastic.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 09-45587 kit weigh?\u003c\/strong\u003e The Johnson Pump 09-45587 Impeller Service Kit weighs 0.2 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many O-rings and gaskets come in this kit?\u003c\/strong\u003e Two O-rings and three gaskets are included in the 09-45587 kit for the F4B-8\/9 pump.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many screws are included, and what are they made of?\u003c\/strong\u003e The kit includes four brass flat head screws and two stainless flat head screws for reassembling the F4B-8\/9 pump.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Johnson Pump part?\u003c\/strong\u003e Yes, part number 09-45587 is a genuine Johnson Pump service kit manufactured for the F4B-8\/9 pump series.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know when it's time to replace the impeller in my F4B-8\/9 pump?\u003c\/strong\u003e Reduced water flow or pressure from an F4B-8\/9 pump is a common sign the impeller needs replacing, at which point the 09-45587 kit provides the impeller along with fresh seals and screws for the job.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for this product?\u003c\/strong\u003e The Johnson Pump 09-45587 Impeller Service Kit has UPC 7330717002480.\u003c\/p\u003e","brand":"Johnson Pump","offers":[{"title":"Default Title","offer_id":49028225466587,"sku":"JON-09-45587","price":45.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/JON-09-45587__39025.1722510279.500.750.jpg?v=1785164627","url":"https:\/\/www.goodvibesmarina.com\/products\/johnson-pump-09-45587-impeller-service-kit-for-f4b-8-9-pumps","provider":"Good Vibes Marina","version":"1.0","type":"link"}
