Abstract
A wear indicator for a sprocket adapted to have an endless track arranged in driving association therewith. The sprocket has opposite side surfaces and a series of sprocket teeth disposed peripherally about the sprocket. Each sprocket tooth has a tip with track engaging surfaces extending away therefrom to define a tooth profile. The sprocket wear indicator includes a visual marker on a side surface of the sprocket for allowing a person to visually gauge wear of the tooth profile on the sprocket.
