PVXH007 | Hayward AquaNaut & Poolvergnuegen Large Drive Gear

OEM Hayward Large Drive Gear PVXH007 is a genuine replacement part designed for AquaNaut 200, 250, 400, 450 and Poolvergnuegen 2- and 4-wheel suction-side pool cleaners. Positioned on the right side of the lower body, this gear transfers rotational power from the turbine and small drive gear to the steering bracket roller, enabling precise wheel movement and navigation. It plays a vital role in directional control and overall cleaning efficiency by working in tandem with the shaft bearing. Built from high-strength materials, this component helps restore smooth operation and is essential for maintaining consistent debris removal across pool surfaces.

Highlights

• OEM Hayward Gear Fit: Compatible with AquaNaut and Poolvergnuegen models 200 to 450 for factory-accurate integration and reliable performance.

• Power Transmission Role: Links the turbine and small drive gear to the steering bracket roller to enable forward motion and directional changes.

• Installs on Right Side: Mounts on the cleaner’s lower right side and interfaces with a shaft bearing to maintain smooth, stable steering cycles.

• Engineered for Pool Use: Constructed from rugged, chemical-resistant materials to withstand daily use in chlorinated water environments.

• Restores Navigation Control: Replacing a worn drive gear improves wheel coordination and helps maintain thorough and efficient pool cleaning.
