A crankshaft having an axis of rotation, comprising:
- a main throw having a web, a main pin extending from the web that is coaxial with the axis of rotation and an aperture in the web;
- a crank throw having a web, a crank pin extending from the web, a central aperture positioned in the web that is coaxial with the axis of rotation, the crank pin positioned in the aperture of the main throw;
- a connecting rod positioned on the crank pin and including a connecting rod bearing positioned about a bearing surface of the crank pin;
- a first set of thrust washers positioned on the crank pin on a first side of the connecting rod, the first set of washers including a first inner thrust washer coaxially positioned within a first outer thrust washer;
- and
- a second set of thrust washers positioned on the crank pin on a second side of the connecting rod opposite the first side, the second set of washers including a second inner thrust washer coaxially positioned within a second outer thrust washer.
A crankshaft having an axis of rotation, comprising:
- a main throw having a web, a main pin extending from the web and coaxial with the axis of rotation, an aperture in the web, an annular recess surrounding the aperture and a groove extending from a side of the web to the annular recess;
- a crank throw having a web, a crank pin extending from the web, a central aperture positioned in the web and coaxial with the axis of rotation, an annular recess surrounding the central aperture and fluidly coupled with an oiling channel having a first passage coupled with the annular recess and a second passage that distributes oil to a bearing surface of the crank pin, the crank pin positioned in the aperture of the main throw;
- a connecting rod positioned on the crank pin.
