A crankshaft (220), and method for distributing lubricant along a crankshaft (220), are disclosed. The crankshaft (220) includes a crank pin (520), a cra nk arm (530), a main segment (510), and a flange (550). The crank arm (530) is coupled between the main segment (510) and the crank pin (520) and has an outer side (565). A channel (650) extends from within the crank pin (520) to the outer side (565). The flange (550) has outer (665) and inner edges (645) , is positioned on the main segment (510) so that the outer edge (665) abuts t he main segment(510), and is further positioned so the inner edge abuts the out er side of the crank arm (530). The flange (550) has first (630) and second grooves (640) along the outer (665) and inner edges (645) of the flange (550 ), respectively, and the grooves (630,640) form a passage extending from the channel (650) to an exterior portion of the main segment (510), so that lubricant can flow between the exterior portion of the main segment (510) an d the channel (650) via the passage.
