This assembly powers the gearbox that converts pressurized water flow into mechanical motion, driving the cleaner’s wheels and enabling it to scrub pool floors, walls, and steps — just like new. Precision-engineered to match original factory specifications, it ensures smooth rotation, reliable torque, and consistent movement throughout cleaning cycles, extending the life of your cleaner without needing a full unit replacement.\u003c\/p\u003e\n\u003ch3 data-start=\"755\" data-end=\"771\"\u003eHighlights\u003c\/h3\u003e\n\u003cul data-start=\"772\" data-end=\"1766\"\u003e\n\u003cli data-start=\"772\" data-end=\"966\"\u003e\n\u003cp data-start=\"774\" data-end=\"966\"\u003e\u003cstrong data-start=\"774\" data-end=\"804\"\u003eOEM-Authentic Replacement:\u003c\/strong\u003e Genuine Polaris part (R0547400) designed specifically for the 3900 Sport cleaner, ensuring perfect fit and compatibility.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"967\" data-end=\"1178\"\u003e\n\u003cp data-start=\"969\" data-end=\"1178\"\u003e\u003cstrong data-start=\"969\" data-end=\"1005\"\u003eRestores Full Drive Performance:\u003c\/strong\u003e Rebuilds the internal gearbox “motor,” giving the cleaner back the torque and drive needed to climb walls and cover the entire pool.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1179\" data-end=\"1380\"\u003e\n\u003cp data-start=\"1181\" data-end=\"1380\"\u003e\u003cstrong data-start=\"1181\" data-end=\"1207\"\u003eCost-Effective Repair:\u003c\/strong\u003e Lets you avoid full cleaner replacement — just swap the worn gear assembly to regain original performance at a fraction of the cost.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1381\" data-end=\"1566\"\u003e\n\u003cp data-start=\"1383\" data-end=\"1566\"\u003e\u003cstrong data-start=\"1383\" data-end=\"1408\"\u003eDurable Construction:\u003c\/strong\u003e Built to withstand pool water exposure, pressure-side flow, and repeated mechanical cycles for long-term reliability.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1567\" data-end=\"1766\"\u003e\n\u003cp data-start=\"1569\" data-end=\"1766\"\u003e\u003cstrong data-start=\"1569\" data-end=\"1589\"\u003eEasy to Install:\u003c\/strong\u003e Drop-in replacement — rebuild your existing gearbox without the need for special tools or professional service, simplifying maintenance.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePolaris 3900 Sport Pool Cleaners\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-start=\"523\" data-end=\"542\"\u003eAdditional Info\u003c\/h3\u003e\n\u003cp data-start=\"543\" data-end=\"955\"\u003eThe Polaris R0547400 Turbine Gear Assembly rebuilds the internal drive mechanism that powers the 3900 pressure-side cleaner’s wheels and movement.

Bringing your old gear housing to Discount Pool Mart allows staff to verify the match quickly.\u003c\/p\u003e\n\u003ch4 data-start=\"1328\" data-end=\"1402\"\u003eWill this gear assembly work if my cleaner only moves intermittently?\u003c\/h4\u003e\n\u003cp data-start=\"1403\" data-end=\"1545\"\u003eYes, intermittent movement often indicates internal gear wear. Replacing the turbine gear assembly typically restores continuous drive motion.\u003c\/p\u003e\n\u003ch4 data-start=\"1547\" data-end=\"1608\"\u003eCan this part fix a cleaner that no longer climbs walls?\u003c\/h4\u003e\n\u003cp data-start=\"1609\" data-end=\"1760\"\u003eOften yes. When the gear set loses torque, the cleaner cannot generate upward traction. Installing R0547400 usually restores wall-climbing performance.\u003c\/p\u003e\n\u003ch2 data-start=\"1762\" data-end=\"1799\"\u003eInstallation and Troubleshooting\u003c\/h2\u003e\n\u003cp data-start=\"1800\" data-end=\"1895\"\u003eWalk-in customers frequently ask how to diagnose worn gears or identify other potential issues.\u003c\/p\u003e\n\u003ch4 data-start=\"1897\" data-end=\"1953\"\u003eWhat symptoms suggest my gear assembly is worn out?\u003c\/h4\u003e\n\u003cp data-start=\"1954\" data-end=\"2070\"\u003eGrinding noises, jerky wheel movement, or the cleaner stalling during cycles are common signs of internal gear wear.\u003c\/p\u003e\n\u003ch4 data-start=\"2072\" data-end=\"2126\"\u003eDo I need special tools to install this assembly?\u003c\/h4\u003e\n\u003cp data-start=\"2127\" data-end=\"2264\"\u003eNo, most customers can replace it with basic hand tools.
