Zusammenfassung:	A balancing system for different compressors utilizes a counterweight (50) having a common exterior configuration. The mass of the counterweight is optimized for each compressor by changing the size of a recess (96) located in the counterweight. In one embodiment, the recess is an arcuately shaped recess; and in another embodiment, the recess is a plurality of holes.
