Abstract: A cam roller pin for mounting a cam roller with a substantially uniform width to a rocker lever includes a substantially cylindrical pin body bounded by a pair of oppositely-disposed ends and having a length which extends from one end to the opposite end, the pin body defining an oblong trough therein which has a length that is at least 30 percent of the length of the pin body. The pin body has an outer surface which defines a passageway extending from the outer surface through the pin body and into one end of the oblong through. The passageway is configured with two portions having different entry locations into the pin body and the passageway provides a path for lubrication from the exterior of the cam roller pin to the oblong trough.
