Riders and mechanics use this kit when coolant weeps from the weep hole, the impeller shaft develops play, or a top-end refresh is already underway. The kit covers the parts that commonly fail, so the pump can be returned to service without sourcing each piece individually.\u003c\/p\u003e\u003ch4\u003eBuilt For Performance\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSeals and gaskets sized for the WR450F pump housing\u003c\/li\u003e\n\u003cli\u003eBearing and shaft components designed to handle continuous coolant exposure\u003c\/li\u003e\n\u003cli\u003eConstruction suited to the heat cycling of off-road engine operation\u003c\/li\u003e\n\u003cli\u003eDirect replacement for the original pump internals\u003c\/li\u003e\n\u003cli\u003eKit format reduces downtime by grouping wear items together\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFits These Machines\u003c\/h4\u003e\u003cul\u003e\u003cli\u003efor Yamaha WR450F 2024\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003eOn-The-Job Use\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCooling system refresh during a top-end or full engine rebuild\u003c\/li\u003e\n\u003cli\u003eRepair of coolant leaks at the pump weep hole\u003c\/li\u003e\n\u003cli\u003ePreventive maintenance on high-hour off-road machines\u003c\/li\u003e\n\u003cli\u003eTrailside or workshop service before a race weekend\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecs At A Glance\u003c\/h4\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Number(s)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eWR 450F kit reference\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMachine\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003efor Yamaha WR450F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel Year\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2024\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSystem\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eWater pump rebuild\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch4\u003eGood To Know\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Do I need to drain the coolant before installing this kit? \u003cstrong\u003eA:\u003c\/strong\u003e Yes, the cooling system should be drained and the pump housing removed to access the internals this kit replaces.
