A cylindrical conveyor of an agricultural harvester comprises: a hollow conveyor cylinder having a center and a central rotational axis; a plurality of conveyor fingers extending through apertures on the hollow conveyor cylinder; an offset shaft having a longitudinal axis that is elongate and has two opposing ends, and to which the plurality of fingers are coupled for free rotation, the offset shaft being disposed inside the hollow conveyor cylinder and offset from the central rotational axis, wherein the longitudinal axis is parallel to the central rotational axis; first and second central shafts disposed inside the hollow conveyor cylinder and coaxial with the central rotational axis of the hollow conveyor cylinder; two timing cranks fixed to the first and second central shafts and to the opposing ends of the offset shaft, wherein each of said two timing cranks is an elongate unitary body having a first end and a second end, wherein the first end defines a first aperture in the unitary body with a first longitudinal axis, wherein the second end defines a second aperture in the unitary body with a second longitudinal axis, and further wherein each of the apertures are joined by a longitudinal slot extending between and being in communication with the first and second apertures. |
