Zodiac – Complete gear box assembly grey C – R0632303

The Zodiac R0632303 is a genuine OEM replacement complete gear box assembly (grey, C side) designed specifically for the Zodiac CX20, CX20 Tile, CX35, and CX35 Tile robotic pool cleaners. The gear box is a critical mechanical component responsible for translating motor output into the controlled drive movement of the cleaner’s tracks, enabling the robot to navigate pool surfaces efficiently. This assembly corresponds to Part No. 8 in the official Zodiac CX series parts diagram, making identification and ordering straightforward for technicians and pool owners alike.

Being a complete assembly, this unit arrives ready to install without requiring additional sub-components to be sourced separately. It includes the gear box housing together with the associated tracks, ensuring that the drive side of the cleaner is fully restored to factory specification upon replacement. The grey colour coding identifies this as the C-side assembly within the drivetrain layout of the CX series robots.

Technical characteristics and compatibility

This gear box assembly is manufactured to Zodiac’s original specifications, ensuring precise fit and reliable mechanical engagement within the CX20 and CX35 chassis. Robotic pool cleaners rely on their gear boxes to convert rotational energy from the internal motor into linear track movement, and a worn or damaged gear box will result in reduced traction, erratic movement, or complete drive failure. Replacing the complete assembly rather than individual internal gears restores full mechanical integrity and extends the operational life of the robot.

The assembly is compatible with the following models: CX20, CX20 Tile, CX35, and CX35 Tile. The inclusion of tracks within the package means the entire drive unit can be replaced in a single service operation, minimising downtime and ensuring matched wear characteristics across all drive components. As a genuine Zodiac spare part, it meets the tolerances required for correct function within these robotic cleaners.

Suitability and buying context

This part is intended for pool owners and service technicians maintaining Zodiac CX20 or CX35 series robotic pool cleaners. It is the correct choice when the cleaner exhibits symptoms such as track slipping, uneven movement, grinding noises from the drive unit, or complete loss of drive on one side. Because the CX series robots are used across a range of in-ground pool types including tiled and standard finishes, this assembly is relevant to a broad range of domestic pool installations. Always verify your specific model number against the compatibility list before purchasing to ensure correct fitment.
