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: What to Look for in a Robotic Pool Cleaner Gear Kit
Compatibility with Your Cleaner Model
The most critical factor is whether the gear kit fits your specific robotic pool cleaner. Kits are often designed for a narrow range of models. For example, the Zodiac Polaris Drive Gear Kit works only with Polaris 9300 and 9300xi Sport models, while the Pokin combo kit is made for Dolphin Maytronics units like the M200, M400, and Nautilus CC Plus. Always verify your cleaner’s model number before ordering. If you’re unsure, consult the Replacement Parts category for model specific guides.
Material Quality and Durability
Pool environments are harsh: chlorine, UV rays, and constant moisture. Look for gear kits made from corrosion resistant materials like POM plastic or heavy duty rubber. The R0639000 Drive Gear uses POM for wear resistance, while the climbing rings in the Hihitomorrow kit are built from robust rubber to handle repeated wall climbs. Cheap plastic parts will crack quickly, so prioritize durability over low cost.
Ease of Installation
Most gear kits are designed for DIY installation, but some require more disassembly than others. Snap fit gears like the R0639000 need no tools, while the Hayward Rebuild Kit involves replacing the entire lower body and may take an hour. If you’re not handy, look for kits with clear instructions or video tutorials. For motor related repairs, see our Polaris robotic pool cleaner motor guide.
Completeness of the Kit
A good gear kit should include all the parts you need for a specific repair. The Pokin combo kit comes with climbing rings, timing tracks, guide wheels, and pulley gears, making it a one stop rebuild for Dolphin cleaners. The Pooloob PF1 kit includes brushes and wheel rings for basic maintenance. Avoid buying individual parts if a comprehensive kit is available, as it saves time and ensures matched components. For other motor upgrades, explore AIPER replacement motor options.
Final Thoughts
Choosing the right robotic pool cleaner gear kit depends on your cleaner’s brand and the specific failure you’re addressing. For a simple, affordable refresh of the brushes and traction rings, the Pooloob PF1 Robotic Pool Cleaner Replacement Parts is a solid pick. If you need a full lower body overhaul to upgrade an older cleaner to a modern 4 wheel system, the Rebuild Kit, Lower Body, The Pool Cleaner 4-Wheel from Hayward delivers comprehensive coverage and durability. Both options will have your robotic pool cleaner climbing and scrubbing like new again.
