Design and build quality are straightforward. The white plastic wheels and gears match the original specifications, and the set includes everything needed for a typical replacement. Installation is relatively simple for anyone comfortable with basic disassembly, though you may need a screwdriver and some patience. The parts are not compatible with Nautilus CC or Nautilus CC Pro models, so be sure to check your cleaner before purchasing.

If you own a Maytronics Dolphin pool cleaner and notice reduced movement or slipping, worn guide wheels and gears are often the culprit. The ANTOBLE replacement parts kit offers a straightforward fix. It includes four guide wheels and two pulley gears designed to fit a broad range of Dolphin models, from the Nautilus CC Plus to the M500 and beyond.
Standout features include the use of high-quality POM material, which is known for its strength and low friction. This means the parts should resist wear far longer than basic plastic alternatives. In use, the wheels and gears restore smooth tracking and traction, helping your cleaner cover the pool floor efficiently.
Build quality appears solid, with precise dimensions matching original parts. The guide wheels measure about 2.05 inches in diameter and 1.06 inches thick, while the pulley gears are slightly larger. Installation is simple, typically requiring just a screwdriver to swap out old components.
One potential downside is that this kit does not work with the older Nautilus CC model, so check your cleaner's model number before buying. Also, the manual measurement note suggests a possible slight variance, though most users should find a proper fit.

Buying Guide: Choosing the Right Dolphin Replacement Gears
Selecting the correct set of gears ensures your Dolphin pool cleaner regains its original mobility and cleaning power. Focus on these key factors when shopping.
Compatibility with Your Dolphin Model
Not all gears fit every Dolphin model. Genuine parts often list specific model numbers, while aftermarket sets typically cover a broader range. Always verify your unit’s model (e.g., Nautilus CC Plus, DX3, Premier) against the part’s compatibility list before ordering. For example, the robotic pool cleaner replacement gear options vary between generations.
Material Quality and Durability
Gears face constant friction and exposure to pool chemicals. Genuine Dolphin parts use high-grade ABS and engineered plastics designed for long life. Aftermarket brands often use reinforced POM or nylon, which can be equally durable at a lower cost. Look for sets that specify heavy-duty, non-corrosive materials to ensure lasting performance.
What’s Included in the Kit
Replacement gear sets vary: some include only pulley gears, while others bundle guide wheels, climbing rings, or timing tracks. A comprehensive kit saves time and money by addressing multiple wear points at once. For a broader overview of available sets, our pool robot replacement gears article covers the full spectrum.
Genuine vs. Aftermarket Parts
Genuine Maytronics parts guarantee a precise fit and carry the manufacturer’s quality promise. Aftermarket parts, like those from ANTOBLE or MNPARTS, can offer excellent value and often include extras like multiple gears and wheels for the same or lower price. Both options can effectively restore your cleaner’s function—your choice depends on budget and preference for OEM certification.
Final Thoughts
Whichever gear set you choose, promptly replacing worn components will breathe new life into your Dolphin pool cleaner, ensuring it navigates walls and scrubs debris efficiently all season. For those who prioritize OEM quality and simplicity, the Dolphin Genuine Replacement Part (4-pack guide wheels with 2 pulley gears) is a reliable, model-specific choice, while the comprehensive 9985006-R2 Repair Kit for Dolphin Nautilus CC from MNPARTS is an exceptional value, bundling timing tracks, climbing rings, and gears in one economical package.

Frequently Asked Questions
How often should I replace Dolphin gears?
With regular use (2 to 3 times per week), inspect gears every 6 to 12 months. Replace them when you notice reduced climbing ability, sluggish movement, or visible wear like cracked or missing teeth. Many owners find swapping them every 1 to 2 years keeps performance optimal.
Can I use aftermarket gears instead of genuine Dolphin parts?
Absolutely. Aftermarket gears from reputable brands like ANTOBLE and MNPARTS are designed for compatibility and often made from high-quality materials. They are a cost-effective alternative, but always double-check that the set supports your specific Dolphin model, as some aftermarket packs exclude newer models like the Nautilus CC.
What are the signs that my Dolphin gears need replacing?
Key signs include your cleaner hesitating or failing to climb walls, making clicking or grinding sounds, leaving dirty streaks, or moving in circles. Visual inspection may reveal cracked, missing, or smooth teeth on the pulley or guide wheels. Prompt replacement prevents further damage to the motor.
Do I need any special tools to replace the gears?
No specialized tools are required; a standard screwdriver is usually enough to remove the wheel assembly and swap out the gears. Most replacement kits come with clear instructions. For detailed guidance, refer to our pool robot replacement gears guide for step-by-step tips.
