Daihatsu 8DK-28 crankshaft

The Daihatsu 8DK-28 crankshaft is a heavy-duty forged steel component that converts the reciprocating motion of the pistons into rotational motion to drive the engine. It is designed to withstand high cyclic loads and torsional stresses encountered in medium-speed marine diesel engines. The crankshaft is precisely machined and dynamically balanced to ensure smooth operation, proper power transmission, and long service life. It is supported by multiple main bearings and includes drilled oil passages for efficient lubrication.
