Key Benefits + Quattro Brush Drive Fitment
- Genuine Polaris OEM left-side brush gearbox
- Designed for compatible Polaris Quattro Sport and Quattro P40 pressure-side cleaners
- Transfers drive motion to the cleaner's left-side brush system
- Replaces a worn, damaged, or failed left brush gearbox
- Side-specific component; not interchangeable with the right-side gearbox
- OEM part number R0838500 helps prevent incorrect replacement-part selection
Fluidra's current Polaris parts catalog identifies R0838500 as the left-hand side brush gearbox, while Polaris parts listings document Quattro Sport and P40 compatibility.
Quick Product Summary
The Polaris R0838500 OEM Left Brush Gearbox is a genuine replacement component for select Polaris Quattro pressure-side cleaners, including documented Quattro Sport and Quattro P40 applications. The gearbox is installed on the cleaner's left side and supports operation of the side-brush system. It is intended for repairs where inspection confirms that the original left gearbox is worn, damaged, or no longer operating correctly. Confirm your cleaner model, left-side position, and R0838500 before ordering.
Best For
- Polaris Quattro Sport repairs
- Polaris Quattro P40 repairs
- Replacing a failed left brush gearbox
- Side-brush drive-system service
- Quattro cleaner rebuilds
- Pool professionals ordering by Polaris OEM number
Why This Matters
- The left-side brush gearbox is part of the Quattro brush-drive system
- A damaged gearbox can interfere with proper brush operation
- Left and right brush gearboxes use separate part numbers
- Matching R0838500 helps prevent ordering the right-side R0838400 gearbox
- The side brushes themselves are separate from the gearbox
- Proper diagnosis helps avoid replacing functioning components unnecessarily
Fluidra lists R0838400 as the right-hand gearbox, R0838500 as the left-hand gearbox, and R0838300 as the separate 2-piece side-brush set.
Common Signs You Need This / Use This When
- The left-side brush does not operate and inspection identifies gearbox failure
- The original gearbox is cracked or physically damaged
- Internal gearbox wear has been confirmed during cleaner service
- The left brush drive no longer operates correctly
- Your Quattro parts diagram specifies R0838500
- You are repairing the left-side brush-drive assembly
Brush-operation problems can also involve the brush itself, drive shaft, main gearbox, or related components, so inspect the cleaner before assuming the left gearbox alone is the cause.

Buy with Confidence
Benchmark Pool Supply helps customers identify Polaris cleaner replacement parts using OEM numbers, cleaner models, and actual repair applications. With Quattro brush components, distinguishing the left gearbox, right gearbox, and side brushes is especially important because each has a separate Polaris part number.
For R0838500, confirm that your cleaner is a compatible Quattro model and that the left-side brush gearbox is the component requiring replacement.
