It meshes with the engine's accessory drive train to spin the compressor, which generates the pressurized air needed for a truck's braking system. This gear is typically replaced if the original has worn, chipped, or broken teeth, or as a preventative measure during a major engine overhaul or compressor replacement to ensure reliable air system operation.
