Abstract
An engine assembly having a cover for catching oil splatted by crankshaft gear and a balance shaft gear is provided. The crankshaft gear is mechanically coupled to the balance shaft gear. The balance shaft gear may be partially submerged in a pool of oil formed at the bottom of the crankcase housing. The cover includes a first cover portion having a back wall and a pair of side walls extending along a top portion and a bottom portion. The top portion covers a respective portion of a circumferential edge of the crankshaft gear. The bottom portion a respective portion of a circumferential edge of the balance shaft gear. Accordingly, oil splattered by the crankshaft gear and the balance shaft gear is caught by the cover, reducing oil entrainment and increasing oil pumping efficiency. Further, the cover helps prevent oil mist from escaping the system so as to reduce oil consumption.
