Claim:
1. An eccentric assembly for vibratory compaction comprising: an outer eccentric member that is longitudinally elongated cylinder shaped and has a partial longitudinal opening through the length; an inner eccentric member that is longitudinally elongated cylinder shaped and has a partial longitudinal opening through the length and rotatably connected inside of said outer eccentric member so that the inner eccentric member can rotate with respect to the outer eccentric member around the same axis of rotation; a pin member that is fitted into the bores of the inner eccentric member and outer eccentric member thus rotatably connects said inner eccentric member and said outer eccentric member together; and bushings that are press fitted between the inner eccentric member and said pin member so that the bushings give enough friction to the inner eccentric member to rotate with respect to the outer eccentric member.
