Abstract

Official abstract text for this publication.

A PTO shaft is disclosed that includes an inner shaft having a first spline gear at the proximal end, and a notch proximate to the distal end. The PTO also includes a hollow outer shaft removably disposed over at least a portion including the notch of the inner shaft. The outer shaft comprises a second spline gear configured to mate with the first spline gear. The PTO also includes a self-lubricating sleeve disposed on the notch of the inner shaft and configured to contact both the inner shaft and the outer shaft. The PTO also includes a seal disposed on the inner shaft between the first spline gear and the notch to resist movement of a lubricating oil from the proximal end of the inner shaft to the notch.

First claim
