ABSTRACT:
An improved crank apparatus for a crankshaft of a diesel engine including an arm extending outwardly of the crankshaft, a crank pin affixed to the arm and having a generally rectangular configuration, a split sleeve having a slot formed therein so as to receive the crank pin therein, and a piston rod affixed to the split sleeve and having an insert key affixed thereto so as to reside within the split sleeve in contact with the crank pin during a rotation of the crankshaft. The crank pin includes a first tab extending outwardly therefrom and a second tab extending outwardly from an opposite side of the crank pin. The first and second tabs extend through an opening formed in the split sleeve from the slot. These tabs include chamfered edges extending away from the generally rectangular configuration. The insert key is positioned so as to reside within an interior area of the split sleeve as the crankshaft rotates.
