Restore the Polaris 3900 Sport Internal Drive System
- Genuine Polaris replacement turbine gear assembly for the Polaris 3900 Sport pressure-side pool cleaner.
- Direct replacement part number R0547400 for the 3900 Sport internal drivetrain.
- Sold as one turbine gear assembly.
- The Polaris 3900 Sport parts diagram shows three R0547400 turbine gear assemblies are used in one cleaner.
- Useful when servicing worn, damaged, binding, or stripped internal drivetrain components.
Quick Product Summary
The Polaris R0547400 Turbine Gear Assembly is a genuine replacement drivetrain component for the Polaris 3900 Sport pressure-side automatic pool cleaner. 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.
Polaris 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.
A 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.
Best For
Repairing 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.
Why This Matters
- The turbine gear assembly is part of the 3900 Sport drive system that supports cleaner movement.
- Worn gear teeth or binding components can reduce smooth power transfer through the drivetrain.
- Using the exact Polaris replacement part helps maintain correct alignment with the surrounding 3900 Sport drive components.
- Knowing that the cleaner uses three turbine gear assemblies helps technicians inspect the complete set instead of replacing one part blindly.
Common Signs / Use This When
- The cleaner has water flow but the wheels do not drive normally.
- You hear clicking, skipping, grinding, or binding from the internal drivetrain.
- Inspection shows damaged, worn, or stripped turbine gear teeth.
- The chain and sprockets move inconsistently and the turbine gear has been identified as the worn component.
- Your Polaris 3900 Sport parts diagram calls for R0547400.

Compatibility / Fitment Notes
R0547400 is specifically identified for the Polaris 3900 Sport / P39 cleaner. Do not assume compatibility with Polaris 180, 280, 360, 380, Quattro, or other cleaner families unless their parts documentation specifically lists R0547400.
The 3900 Sport schematic shows three R0547400 turbine gear assemblies and two R0547500 drive sprocket assemblies in the drivetrain. This listing is for one R0547400 turbine gear assembly. Inspect all related drivetrain components before ordering repair parts.
Installation / Use Notes
Turn off the booster pump and pool circulation equipment before removing the cleaner from the pool for service. Open the cleaner according to the Polaris service procedure and inspect the turbine gears, chain, sprockets, gearbox, wheel bearings, and wheel assemblies for wear or damage.
Replace the damaged turbine gear assembly in the correct position and verify that surrounding drivetrain components move freely and engage correctly before reassembly. If multiple turbine gears are worn, replace the quantity required by inspection. Follow current Polaris service instructions for disassembly and reassembly.
Buy with Confidence
Benchmark Pool Supply helps customers match Polaris cleaner parts by exact model, manufacturer part number, and drivetrain position. The 3900 Sport uses several similar-looking internal drive components, so matching R0547400 specifically to the turbine gear location helps reduce wrong-part orders.
