Abstract: Methods and systems are provided for a crankshaft damper cover for a crankshaft damper of a crankshaft in an engine. In one example, a crankshaft damper cover shaped to fit within a cavity of a crankshaft damper and including an inset and an annular ring embedded within the inset, where the annular ring includes tabs adapted to mate with an inner surface of the crankshaft damper. As one example, the inset may be comprised of a damping material, such as plastic or foam.

Abstract: Systems are provided for a damper cover for an engine crankshaft damper. In one example, a damper cover may include a frame and an inset, with extensions of the frame adapted to couple to slots of an engine crankshaft damper, and with portions of the inset positioned between each extension and each corresponding slot. As one example, the frame may be comprised of metal and the inset may be comprised of a damping material such as foam or rubber.

Abstract: A crankshaft for an engine, includes: a first number of main journals including a head main journal positioned between one or more first-side main journals and one or more second-side main journals, the head main journal supporting a grooved shell with one or more oil grooves, a second number of pin journals including one or more first-side pin journals and one or more second-side pin journals, the head main journal connected to and being positioned between the first-side and second-side pin journals, a first extended passageway defined by and in communication with the head main journal, the one or more first-side main journals and the one or more first-side pin journals, and a second extended passageway defined by and in communication with the head main journal, the one or more second-side main journals and the one or more second-side pin journals.

Abstract: A parting line strategy for a crankshaft (100) includes providing a parting line that has a plurality of portions that extend across a plurality of cheeks (104, 106, 108) and pins (120, 126, 136, 142, 152, 158). Further, the parting line has a portion (126, 142, 158) that extends generally diagonally across a face (168) of each of the plurality of cheeks (104, 106, 108) to assist in removing flash from the crankshaft (108).
