Patent ID: 8156831

Claim:
A power take-off shaft comprising: a first shaft means comprising an outer periphery, a proximal end, a distal end, a spline gear means proximate to the proximal end, and a notch proximate to the distal end; a second shaft means configured to fit over at least a portion including the notch of the first shaft means, the second shaft means comprising a spline gear means proximate to the proximal end, the spline gear means of the second shaft configured to cooperate with the spline gear means of the first shaft so as to prevent rotary motion of the first shaft with respect to the second shaft; a self-lubricating sleeve means disposed on the notch of the first shaft means, the sleeve means configured to contact both the first shaft means and the second shaft means; and a sealing means disposed on the first shaft means between the spline means and the sleeve means, the sealing means configured to sealingly contact the first shaft means and the second shaft means so as to resist movement of lubricating oil from the proximal end to the distal end.
