It is used inside the cleaner as part of the internal drive system that works with the chain, sprockets, gearbox, and wheel assemblies to keep the cleaner moving across the pool surface.\u003c\/p\u003e\u003cp\u003ePolaris identifies R0547400 as the Turbine Gear Assembly in the current 3900 Sport \/ P39 parts diagram. The diagram specifies a quantity of three turbine gear assemblies per cleaner. This product is sold as one replacement assembly, so inspect the complete drivetrain before ordering and select the quantity needed for your repair.\u003c\/p\u003e\u003cp\u003eA worn or damaged turbine gear can contribute to drivetrain problems such as slipping, binding, uneven wheel movement, or a cleaner that receives water pressure but does not drive correctly. Because the 3900 Sport drivetrain uses several interacting parts, inspect the chain, chain tensioner, drive sprockets, gearbox, wheel sprockets, bearings, and wheels before assuming the turbine gear is the only failed component.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cp\u003eRepairing the internal drivetrain of a Polaris 3900 Sport when inspection identifies a worn, damaged, stripped, or binding turbine gear assembly and the cleaner parts diagram calls for R0547400.\u003c\/p\u003e\u003ch2\u003eWhy This Matters\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThe turbine gear assembly is part of the 3900 Sport drive system that supports cleaner movement.\u003c\/li\u003e\n\u003cli\u003eWorn gear teeth or binding components can reduce smooth power transfer through the drivetrain.\u003c\/li\u003e\n\u003cli\u003eUsing the exact Polaris replacement part helps maintain correct alignment with the surrounding 3900 Sport drive components.\u003c\/li\u003e\n\u003cli\u003eKnowing that the cleaner uses three turbine gear assemblies helps technicians inspect the complete set instead of replacing one part blindly.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon Signs \/ Use This When\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThe cleaner has water flow but the wheels do not drive normally.\u003c\/li\u003e\n\u003cli\u003eYou hear clicking, skipping, grinding, or binding from the internal drivetrain.\u003c\/li\u003e\n\u003cli\u003eInspection shows damaged, worn, or stripped turbine gear teeth.\u003c\/li\u003e\n\u003cli\u003eThe chain and sprockets move inconsistently and the turbine gear has been identified as the worn component.\u003c\/li\u003e\n\u003cli\u003eYour Polaris 3900 Sport parts diagram calls for R0547400.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct Specifications\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003ePolaris\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer Part Number\u003c\/td\u003e\n\u003ctd\u003eR0547400\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC \/ Barcode\u003c\/td\u003e\n\u003ctd\u003e052337061278\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eTurbine gear assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCleaner Compatibility\u003c\/td\u003e\n\u003ctd\u003ePolaris 3900 Sport\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCleaner Type\u003c\/td\u003e\n\u003ctd\u003ePressure-side automatic pool cleaner\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Quantity\u003c\/td\u003e\n\u003ctd\u003e1 turbine gear assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity Used Per Cleaner\u003c\/td\u003e\n\u003ctd\u003e3 shown in Polaris 3900 Sport parts diagram\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOEM Status\u003c\/td\u003e\n\u003ctd\u003eGenuine Polaris replacement part\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer Warranty\u003c\/td\u003e\n\u003ctd\u003e90 days\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch2\u003eCompatibility \/ Fitment Notes\u003c\/h2\u003e\u003cp\u003eR0547400 is specifically identified for the Polaris 3900 Sport \/ P39 cleaner.
