Idler Gear Replacement

The Sentry Idler Gear Replacement is a genuine repair part for Better Water Industries Sentry dry pellet chlorinators. This small but essential gear transfers motion within the chlorinator's drive mechanism, helping ensure that chlorine pellets are dispensed accurately and consistently to keep your disinfection system performing exactly as intended day after day. Catching and replacing a worn gear before it fails completely spares you the larger headache of an interrupted chlorination cycle.

Dry pellet chlorinators rely on a precise gear train to meter the right amount of chlorine into the water stream. Over time, gears endure continuous mechanical stress and can wear, chip, or strip teeth, which disrupts dosing and can compromise treatment of the very contaminants the chlorinator is meant to control. Replacing a worn idler gear restores smooth, reliable operation without the expense of replacing the entire chlorinator, making it a cost-effective maintenance choice.
