This Fleck Drive Gear (FL16046) is a genuine Pentair component at the heart of a Fleck control valve's drive train. The drive gear, paired with the pinion, transmits the timer motor's power to the cam and advances the valve through the service and regeneration positions with controlled, accurate motion. It is one of the principal gears responsible for stepping the valve cleanly through its cycle.

This individual gear has been discontinued but remains available within the FL62103-50 service kit, which bundles it with the related drive components most often replaced together. Sourcing the gear through the kit ensures the interacting parts are all fresh and matched for a complete, durable repair rather than mixing a new gear with worn neighbors.

• Genuine Fleck drive gear component
• Transmits motor power to advance the cam
• Works in tandem with the drive pinion
• Available in service kit FL62103-50
• Restores accurate, reliable valve cycling
• Discontinued standalone; sourced through the kit

Because the drive gear is engaged throughout every regeneration, its teeth gradually wear over the life of the valve. Worn or stripped teeth can cause the valve to slip, stall, or skip a position, disrupting the cycle sequence and allowing hard water through to fixtures and appliances. The motor may run while the valve fails to advance, or the unit may make grinding noises as the gears struggle to mesh.

Replacing a worn drive gear alongside its mating pinion is good practice, since damage to one tends to accelerate wear on the other; addressing only one half of the pair can leave the repair short-lived. The FL62103-50 kit makes this straightforward by supplying the matched components together.

Fleck valves remain a mainstay of residential and light-commercial softeners largely because their mechanical drive trains can be rebuilt rather than scrapped when a gear wears out. Installing fresh drive components from the kit returns the gear train to factory tolerance and keeps the system cycling smoothly, regenerating fully, and softening on schedule.

For installers, sourcing the drive gear through the FL62103-50 kit is the practical route now that the standalone part is discontinued, and it conveniently supplies the matched components a proper drive rebuild calls for. Because the gear and pinion wear together, renewing them as a set restores the whole drive train to factory tolerance in a single job, keeping a long-serving Fleck valve cycling reliably.
