Micro pitting is found on the working flank of the pinion gear of the intermediate shaft AHEAD and working flank of the Bull gear of the output shaft.

Micro pitting is a phenomenon that can be found on (hardened) gears. Multiple factors can affect the development of micro pitting, most important factors are surface roughness, lubrication or an incorrect gear mesh. The damage shows itself by a matted grey colour of the teeth. This as outcome of surface fatigue. The development of the micro pitting can be stabilized or progressive. A progressive development can eventually cause more severe pitting, and scaling.
