1. A pin retention system comprising: a pin having a circumferential groove disposed along the pin;a plurality of retention elements sized to sit within the circumferential groove, each of the retention elements including a plurality of holes; anda plurality of dowels sized to slide within the holes in the retention elements;wherein the plurality of retention elements includes four retention elements sized to sit within the circumferential groove;wherein each the four retention elements is arcuate, extends 180 degrees, and is offset relative to another of the four retention elements by 90 degrees within the circumferential groove when the four retention elements are within the circumferential groove. 2. The pin retention system of claim 1, further comprising a washer sized to fit within the circumferential groove. 3. The pin retention system of claim 1, wherein the pin includes an end, and wherein at least one of the holes in one of the four retention elements is partially covered by the end of the pin when the retention element is within the circumferential groove. 4. The pin retention system of claim 1, wherein each of the dowels has a length equal to approximately twice a width of one of the retention elements. 5. The pin retention system of claim 1, wherein the pin includes an end, an axial groove extending between the circumferential groove and the end of the pin, and a first stop member sized to sit within the axial groove. 6. The pin retention system of claim 1, wherein each the four retention elements is configured to be inserted into the circumferential groove radially. 7. The pin retention system of claim 6, wherein two of the four retention elements are configured to be inserted into the circumferential groove at a first axial position along the pin, and the other two retention elements are configured to be inserted into the circumferential groove at a second, different axial position along the pin. 8. A method of assembling a pin retention system comprising: inserting a plurality of retention elements into a circumferential groove on a pin, each of the plurality of retention elements including a plurality of holes;inserting a plurality of dowels through the holes in the plurality of retention elements; andinserting a stop member into an axial groove on the pin and fastening the stop member to the pin to prevent the dowels from moving out of the holes of the retention members. 9. The method of claim 8, wherein the step of inserting the plurality of retention elements includes inserting a first retention element into the circumferential groove and inserting a second retention element into the circumferential groove, the second retention element being axially disposed from the first retention element and partially overlapping the first retention element, such that one of the holes of the first retention element is axially aligned with one of the holes of the second retention element. 10. The method of claim 9, wherein the step of inserting the dowels includes inserting a dowel through the aligned holes of the first and second retention elements to couple the first and second retention elements together. 11. The method of claim 10, wherein the step of inserting the plurality of retention elements further includes inserting a third retention element into the circumferential groove such that the third retention element is axially disposed from the second retention element and the third retention element partially overlaps the second retention element, and such that one of the holes of the third retention element is axially aligned with one of the holes of the second retention element. 12. The method of claim 11, wherein the step of inserting the dowels includes inserting a dowel through the aligned holes of the second retention element and the third retention element to couple the second and third retention elements together. 13. The method of claim 12, wherein the step of inserting the plurality of retention elements further includes inserting a fourth retention element into the circumferential groove such that the fourth retention element is axially disposed from both the first retention element and the third retention element and partially overlaps both the first and third retention elements, and such that one of the holes on the fourth retention element aligns with one of the holes on the first retention element, and another one of the holes on the fourth retention element aligns with one of the holes on the third retention element. 14. The method of claim 13, wherein the step of inserting the dowels includes inserting dowels through the aligned holes of the first, third, and fourth retention elements. 15. The method of claim 14, wherein the circumferential groove is a first circumferential groove and the plurality of retention elements are a first plurality of retention elements, and wherein the method further comprises inserting a second plurality of retention elements into a second circumferential groove on the pin, the second plurality of retention elements including a fifth, sixth, seventh, and eighth retention element, each of the fifth, sixth, seventh, and eighth retention elements being inserted into the second circumferential groove such that each of the fifth, sixth, seventh, and eighth retention elements partially overlaps at least one of the other of the fifth, sixth, seventh, and eighth retention elements, and further comprising inserting dowels through holes in the fifth, sixth, seventh, and eight retention elements. 16. The method of claim 15, wherein the axial groove is a first axial groove and the stop member is a first stop member, and wherein the method further comprises inserting a second stop member into a second axial groove on the pin and fastening the second stop member to the pin to prevent the dowels from moving out of the holes of the fifth, sixth, seventh, and eight retention elements. 17. The method of claim 15, further comprising forming the first and second circumferential grooves into the pin. 18. A pin retention system comprising: a pin having a circumferential groove disposed along the pin;a plurality of retention elements sized to sit within the circumferential groove, each of the retention elements including a plurality of holes; anda plurality of dowels sized to slide within the holes in the retention elements;wherein the pin includes an end, an axial groove extending between the circumferential groove and the end of the pin, and a first stop member sized to sit within the axial groove. 19. The pin retention system of claim 18, further comprising a washer sized to fit within the circumferential groove. 20. The pin retention system of claim 18, wherein each of the dowels has a length equal to approximately twice a width of one of the retention elements.
