Product details
The Polaris R0518800 is the genuine drive gear kit for the 9300, 9300xi and 9400 robotic pool cleaners. It supplies the drive gears as a matched set.
Why gears fail
Every hour the cleaner runs, the drive gears carry the whole machine across the floor and up the walls, and grit that gets past the seals grinds at the tooth faces. Over time the teeth round off or chip. The symptom looks like a dead cleaner: it powers up, the motor turns, and the unit either sits still or drags itself in a circle.
Replacing as a set
Gears wear against each other, so fitting one new gear against worn mates just moves the problem along. The kit exists so the meshing parts go in together and the drive comes back to the tolerances it left the factory with.
