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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cp\u003eReplacing a confirmed 9983123 Z12 active-brush gear during brush-drive service on a compatible Maytronics Dolphin robotic pool cleaner.\u003c\/p\u003e\u003ch2\u003eWhy This Matters\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThe active brush depends on its drive components to rotate correctly during a cleaning cycle.\u003c\/li\u003e\n\u003cli\u003eA damaged or worn gear can prevent the brush-drive assembly from operating as intended.\u003c\/li\u003e\n\u003cli\u003eReplacing the individual gear can be more efficient than replacing a larger brush assembly when surrounding components are still serviceable.\u003c\/li\u003e\n\u003cli\u003eExact part-number matching helps avoid confusion with other Maytronics gears used in different cleaner platforms.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon Signs You Need This \/ Use This When\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eYour cleaner parts diagram identifies Active Brush Gear Z12, part 9983123.\u003c\/li\u003e\n\u003cli\u003eThe existing gear has damaged, rounded, cracked or missing teeth.\u003c\/li\u003e\n\u003cli\u003eThe active brush is not being driven correctly and inspection points to the gear rather than the motor or brush assembly.\u003c\/li\u003e\n\u003cli\u003eYou are rebuilding the active-brush drive and the original 9983123 gear shows visible wear.\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\u003eMaytronics\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eRobotic Pool Cleaner Active Brush Gear\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer Part Number\u003c\/td\u003e\n\u003ctd\u003e9983123\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer Part Name\u003c\/td\u003e\n\u003ctd\u003eActive Brush Gear (Z12)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC \/ Barcode\u003c\/td\u003e\n\u003ctd\u003e718117204388\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eActive brush drive system\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConfirmed Model Examples\u003c\/td\u003e\n\u003ctd\u003eDolphin 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 930\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Status\u003c\/td\u003e\n\u003ctd\u003eGenuine Maytronics replacement part\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch2\u003eCompatibility \/ Fitment Notes\u003c\/h2\u003e\u003cp\u003eMaytronics 9983123 is used across multiple active-brush cleaner platforms, and current parts sources list additional compatible models beyond the examples above.
