Pros
- Premium POM material ensures long service life
- Broad compatibility with many Dolphin models
- Practical kit includes all essential parts for replacement
- Easy installation process
- Good value compared to OEM options
Cons

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. As a new product with no reviews yet, long-term durability is unproven but the material choice inspires confidence.
Overall, the ANTOBLE replacement kit is a practical, affordable solution for refreshing your Dolphin cleaner's drive system. If you need a quick fix to restore performance without paying OEM prices, this set is a solid choice.

The RPBKE R0639000 drive gear is a replacement part designed for Zodiac Polaris robotic pool cleaners. It is specifically intended for owners of popular models like the 9300 Sport, 9350 Sport, 9400 Sport, 9450 Sport, 9550 Sport, and 9650iQ. This gear is a common wear item that can cause the pool cleaner to slip, stall, or move unevenly over time.
This gear is made from POM plastic, a material chosen for its resistance to corrosion and wear in humid, chlorinated pool environments. Replacing a worn drive gear with this part helps restore the cleaner's ability to climb walls and maintain consistent coverage. The snap-fit design means no tools are required for installation, which is a significant convenience for DIY repairs.
In terms of design, the gear features 17 points to match the original specifications. It is a direct replacement for OEM part numbers R0639000 and 5313253671, and also works with the R0517200 gearbox kit. Buyers should note that 2WD models require two gears, while 4WD models require three. The all-white construction is simple and functional.
Potential drawbacks include the lack of user reviews, which makes it difficult to gauge long-term durability. Additionally, while the gear is compatible with many models, users should verify their specific cleaner's requirements before purchasing. It is also important to note that this is only the drive gear; other components may need replacement if the cleaner has additional issues.
Overall, the RPBKE R0639000 drive gear offers a budget-friendly way to restore your Polaris pool cleaner's performance. Its easy installation and durable construction make it a solid choice for DIY repairs. If you are experiencing traction problems with your compatible cleaner, this replacement part is worth considering.
Buying Guide for Robotic Pool Cleaner Replacement Gear
Compatibility with Your Cleaner Model
The most important factor is ensuring the gear fits your specific cleaner. Many Dolphin models share common parts like the climbing ring 6101611-R4 and guide wheels 3884997-R6, but always verify your model number. Polaris models such as the 9300 Sport and 9650iQ use specific drive gears like the R0639000. Cross-reference the product compatibility list before ordering to avoid returns. For more on Polaris-specific parts, see our Polaris robotic pool cleaner motor guide.
Material Quality and Durability
Replacement gears are typically made from POM plastic or heavy-duty rubber. POM offers excellent wear and corrosion resistance in chlorinated water, while rubber climbing rings provide grip for wall climbing. The Pokin combo kit uses heavy-duty rubber for climbing rings, while ANTOBLE guide wheels use high-quality POM. Choose materials that match your pool’s chemical balance and usage frequency.
Ease of Installation
Most replacement gears feature snap-fit or screw-in designs that require no special tools. The Zodiac Polaris Drive Gear Kit comes as a simple 2-pack for quick swap, while the R0639000 gear from RPBKE boasts tool-free installation. If you prefer a comprehensive kit, the Pokin combo includes climbing rings, track, and wheels all in one package, reducing the need for multiple purchases. For motor-related repairs, refer to our maytronics replacement motor.
Number of Parts Included
Kits vary from single drive gears to full combo packs. If you need multiple worn parts replaced simultaneously, a combo kit like the Pokin set (4 climbing rings, 2 tracks, 4 guide wheels, 2 pulley gears) offers better value. For targeted fixes, individual gear packs from Zodiac or ANTOBLE suffice. Consider your cleaner’s age and overall wear before deciding.
Final Thoughts
Whether your Dolphin cleaner needs a full refresh or your Polaris model just requires a new drive gear, the right replacement parts can extend its life significantly. For a complete overhaul, the Pool Cleaner Accessories Combo Replacement Kit covers multiple wear points in one affordable bundle. If you own a Polaris 9300 or similar, the Zodiac Polaris Drive Gear Kit, 9300, 2/PK delivers a precise, durable fix at a low cost. Both options have earned strong ratings and will help your cleaner climb, glide, and scrub like new again.
