Balancing: To balance the rotating mass of the lower end of a engine

pyagid

as MC said they take all the spinning parts crank, rods, pistons ETC. and make sure they all balance out properly by adding or removing weight. Similiar to the reasons you would balance a car tire. TO avoid any vibrations

here is a good link that explains it
