1. A counterweight cover for a compressor comprising: an annular body having an outer circumferential portion, an inner circumferential portion opposing said outer circumferential portion, and an upper portion, said inner circumferential portion being spaced apart from and connected to said outer circumferential portion by said upper portion to define a recess, said recess bounded between said upper portion, said inner circumferential portion and said outer circumferential portion and disposed between a compression mechanism and a motor of the compressor; anda suction baffle disposed on said annular body and operable to direct a flow of suction gas within the compressor;wherein said upper portion is monolithically formed with said outer circumferential portion and said inner circumferential portion. 2. The counterweight cover of claim 1, further comprising a wire guide receiving at least one wire to position said at least one wire relative to said annular body. 3. The counterweight cover of claim 2, wherein said wire guide is integrally formed with the counterweight cover. 4. The counterweight cover of claim 1, wherein said inner circumferential portion is attached to a main-bearing housing. 5. The counterweight cover of claim 4, wherein said inner circumferential portion is snap fit to said main-bearing housing. 6. The counterweight cover of claim 1, wherein said inner circumferential portion includes a plurality of flexible fingers engaging a groove disposed in a main-bearing housing to attach said annular body to said main-bearing housing. 7. The counterweight cover of claim 1, further comprising at least one anti-rotation feature preventing relative rotation between the counterweight cover and a main-bearing housing. 8. The counterweight cover of claim 7, wherein said at least one anti-rotation feature includes keyed members extending outwardly from said annular body, said at least one anti-rotation feature aligning said annular body relative to said main-bearing housing. 9. The counterweight cover of claim 1, wherein said suction baffle is integrally formed with said annular body. 10. The counterweight cover of claim 9, further comprising a wire guide integrally formed with said suction baffle. 11. The counterweight cover of claim 1, wherein said suction baffle includes a lip allowing suction gas to flow in a first direction and preventing oil circulation in a second direction. 12. A compressor comprising: a motor assembly at least partially supported by a main-bearing housing; a counterweight cover fixed to said main-bearing housing and including an inner circumferential portion and an outer circumferential portion that cooperate to define a recess, said inner circumferential portion and said outer circumferential portion being coaxially aligned and opposing one another such that said recess is bounded between sa4eLan outer surface of said inner circumferential portion and an inner surface of said outer circumferential portion; a counterweight associated with said motor assembly and at least partially disposed between said inner circumferential portion and said outer circumferential portion within said recess; a suction baffle integrally formed with said counterweight cover and including a concave surface facing an inlet passage of the compressor, said concave surface being adapted to redirect a flow of suction gas from said inlet passage and facing away from said inner surface of said outer circumferential portion; and a wire guide integrally formed with said counterweight cover. 13. The compressor of claim 12, wherein said wire guide receives at least one wire to position said at least one wire relative to said counterweight cover. 14. The compressor of claim 12, further comprising a wire guard cooperating with said wire guide to protect and route at least one wire. 15. The compressor of claim 14, wherein said wire guard includes a mounting stud engaging said main-bearing housing. 16. The compressor of claim 14, wherein said wire guard includes a rib adapted to maintain a spaced apart relationship between said at least one wire and a shell of the compressor. 17. The compressor of claim 14, further comprising a lanyard including a flag portion and a clip portion retaining a lead wire connected to said at least one wire. 18. The compressor of claim 12, wherein the inner circumferential portion of said counterweight cover is snap fit to a hub of said main-bearing housing. 19. The compressor of claim 12, wherein said counterweight cover includes a plurality of flexible fingers engaging a groove disposed in said main-bearing housing to attach said counterweight cover to said main-bearing housing. 20. The compressor of claim 12, further comprising at least one anti-rotation feature preventing relative rotation between said counterweight cover and said main-bearing housing. 21. The compressor of claim 20, wherein said at least one anti-rotation feature includes keyed members extending outwardly from said counterweight cover, said at least one anti-rotation feature aligning said counterweight cover relative to said main-bearing housing. 22. The compressor of claim 12, wherein said counterweight is attached to one of a driveshaft and a rotor of said motor assembly. 23. The counterweight cover of claim 1, wherein said recess is operable to receive a counterweight therein. 24. A compressor comprising: a motor assembly at least partially supported by a main-bearing housing; a counterweight cover fixed to said main-bearing housing and including an inner circumferential portion and an outer circumferential portion that cooperate to define a recess, said inner circumferential portion and said outer circumferential portion being coaxially aligned and opposing one another such that said recess is bounded between said inner circumferential portion and said outer circumferential portion; a counterweight associated with said motor assembly and at least partially disposed between said inner circumferential portion and said outer circumferential portion within said recess; a suction baffle integrally formed with said counterweight cover; a wire guide integrally formed with said counterweight cover; and a wire guard cooperating with said wire guide to protect and route at least one wire and including a mounting stud engaging said main-bearing housing. 25. The compressor of claim 24, wherein said suction baffle includes a concave surface facing an inlet passage of the compressor, said suction baffle being adapted to redirect a flow of suction gas from said inlet passage. 26. The compressor of claim 24, wherein said wire guide receives at least one wire to position said at least one wire relative to said counterweight cover. 27. The compressor of claim 24, wherein said wire guard includes a rib adapted to maintain a spaced apart relationship between said at least one wire and a shell of the compressor. 28. The compressor of claim 24, further comprising a lanyard including a flag portion and a clip portion retaining a lead wire connected to said at least one wire. 29. The compressor of claim 24, wherein the inner circumferential portion of said counterweight cover is snap fit to a hub of said main-bearing housing. 30.
