Durable build for long-lasting performance

Crafted from crack-resistant material and featuring high-strength, wear-resistant internal gears, this gear box is built for long-lasting performance underwater. Precision-molded teeth help maintain consistent rotation cycles, stable suction distribution, and reliable operation across seasons.

Every unit undergoes quality testing to meet or exceed OEM specifications, helping you keep your cleaner performing reliably between maintenance cycles.

Easy installation steps

To install, separate the pool vacuum’s middle body and lower housing to expose the gear box. Swap in the AXV408P, then apply underwater lubricant before sealing the unit. A quick built-in test confirms proper function.

• Underwater lubrication is recommended during installation
• Test rotation by blowing into the square end to hear a high spin
• Double-check your model number before purchasing
