This patent describes for use with an opposed eight piston engine having a housing, the pistons lying in a predetermined plane, an elongated crank shaft rotatably mounted in the housing. The crank shaft has four crank pins. A balancing arrangement for offsetting the primary couple is imposed on the crank shaft by the piston reciprocation comprising: a first counter weight attached to the crank shaft at a first predetermined angular position with respect to the crank pins of the crank shaft so that upon rotation of the crank shaft, the first counter weight rotates in a first plane, a second counter weight attached to the crank shaft at a second predetermined angular position with respect to the crank pins of the crank shaft so that, upon rotation of the crank shaft, the second counter weight rotates in a second plane, the counter weights being axially spaced from each other, a first idler means, means for rotatably mounting the first idler means to the housing in a plane substantially coplanar with the first plane, a second idler means, means for rotatably mounting the second idler means to the housing in a plane substantially coplanar with the second plane, and means for rotatably driving the idler means in synchronism with the crank shaft.
