Maytronics 9983018 Dolphin Active Brush Gear Z12

Key Benefits + Dolphin Cleaner Compatibility

• Genuine Maytronics replacement Active Brush Gear Z12 for compatible Dolphin robotic pool cleaners.
• Maytronics part number 9983018.
• Designed as part of the active brush drive system that transfers motion to the cleaner's active scrubbing brush.
• Compatible model listings include Dolphin Active 10, E10, Nautilus CC, S50, Echo, Escape, Encore, Cayman, Saturn, Prowler 910, Proteus DX3, and S100 applications.
• Replacing a worn or damaged gear can restore proper active-brush drive operation when the gear itself is the failed component.

Quick Product Summary

The Maytronics 9983018 Active Brush Gear Z12 is a genuine OEM replacement gear used in the active brush drive system of compatible Dolphin robotic pool cleaners. The small Z12 gear works with the active brush mechanism, making it an important service component when a compatible cleaner's brush-drive gear is worn, stripped, cracked, or otherwise damaged. Maytronics parts references and established pool-parts distributors list 9983018 across multiple Dolphin cleaner families, including Active 10, E10, Nautilus CC, S50, S100, Echo, Escape, Encore, Cayman, Saturn, Prowler 910, and Proteus DX3. Verify the exact cleaner model and part number before ordering because Dolphin models can use different brush-drive components.

Best For

• Repairing a compatible Dolphin robotic cleaner with a worn or damaged active brush gear
• Active brush drive service on models that call for Maytronics 9983018
• Pool professionals replacing the individual Z12 gear instead of a larger brush assembly when appropriate
• Keeping a common genuine Dolphin brush-drive service part on hand

Why This Matters

• The gear is part of the mechanism that drives the active scrubbing brush.
• A damaged or stripped gear can prevent the active brush from being driven correctly.
• Using the correct genuine Maytronics part helps maintain proper fit with the surrounding brush-drive components.
• Matching by cleaner model and part number reduces the risk of ordering a visually similar but incompatible gear.

Common Signs You Need This / Use This When

• The active brush is not being driven and inspection identifies the Z12 gear as worn, stripped, cracked, or damaged.
• Your cleaner parts diagram or service reference calls for Maytronics 9983018.
• You are servicing a compatible Dolphin cleaner and replacing the individual active brush drive gear.

Product Specifications

Compatibility / Fitment Notes

Part 9983018 is listed for multiple Dolphin robotic cleaner models, but model families and production revisions can use different brush-drive components. Confirm the exact cleaner model and verify that the parts diagram or existing component calls for 9983018 before ordering. Do not select the replacement by appearance alone.

Installation / Use Notes

Disconnect the robotic cleaner from its power supply before service. Access the active brush drive area according to the cleaner manufacturer's service procedure, inspect the surrounding brush-drive components for wear or damage, and replace the gear in its correct orientation. Reassemble the cleaner fully before reconnecting power. If additional drive components are worn or damaged, replacing only the gear may not correct the underlying problem.
