Quick Product Summary
The Maytronics 9983123 Active Brush Gear is the Z12 gear used in the active-brush drive system of many Dolphin robotic pool cleaners. Maytronics parts catalogs identify 9983123 as “Active Brush Gear (Z12),” and current parts listings confirm it across a broad group of cleaners including Dolphin S200, S300, S300i, Active 20, Active 30, Active 30i, Triton PS, Triton PS Plus, Discovery, Premium, Quantum, Proteus DX4/DX5i, T35, T45, T55i, Pentair Prowler 920 and Prowler 930, plus additional compatible models.
This gear is part of the mechanism that drives the active scrubbing brush. Because several Maytronics cleaner families use similar-looking gears, bushings, adapters and wheel components, the safest way to order is to match your cleaner’s exploded parts diagram to part number 9983123 rather than selecting by appearance alone.
Best For
Replacing a confirmed 9983123 Z12 active-brush gear during brush-drive service on a compatible Maytronics Dolphin robotic pool cleaner.
Why This Matters
- The active brush depends on its drive components to rotate correctly during a cleaning cycle.
- A damaged or worn gear can prevent the brush-drive assembly from operating as intended.
- Replacing the individual gear can be more efficient than replacing a larger brush assembly when surrounding components are still serviceable.
- Exact part-number matching helps avoid confusion with other Maytronics gears used in different cleaner platforms.
Common Signs You Need This / Use This When
- Your cleaner parts diagram identifies Active Brush Gear Z12, part 9983123.
- The existing gear has damaged, rounded, cracked or missing teeth.
- The active brush is not being driven correctly and inspection points to the gear rather than the motor or brush assembly.
- You are rebuilding the active-brush drive and the original 9983123 gear shows visible wear.

Compatibility / Fitment Notes
Maytronics 9983123 is used across multiple active-brush cleaner platforms, and current parts sources list additional compatible models beyond the examples above. Fitment should still be verified against the exact cleaner model and exploded parts diagram. Do not assume every Dolphin robotic cleaner uses the same Z12 gear simply because the part looks similar.
Installation / Use Notes
Disconnect the robotic cleaner from its power source before service. Access the active-brush drive according to the service procedure for your cleaner, note the original gear position and orientation, and replace the worn 9983123 gear. Inspect nearby bushings, adapters, holders, brush components and drive parts before reassembly. Confirm the mechanism moves freely before returning the cleaner to service.
Buy with Confidence
Benchmark Pool Supply helps customers identify Maytronics replacement parts by exact OEM number, cleaner model and repair location. For internal Dolphin brush-drive components, matching part number 9983123 to the correct cleaner platform is the best way to reduce wrong-part orders.
