Two of these 50-tooth gears are used per engine — one mounted on the crankshaft and one on the balance shaft — meshing together to spin the balance shaft at precisely crankshaft speed in the opposite direction. Worn, chipped, or incorrectly meshed balance gears cause a characteristic gear whine at engine RPM and can lead to balance shaft misalignment and crankcase damage.
