In this video, we walk you through the complete process of replacing the crankshaft on a Hitachi EX200-5 excavator with a D6D engine. You'll see a detailed demonstration of crankshaft removal, inspection for wear or bending, and installation of the new forged steel component. We also explain when this critical repair is necessary—such as after engine vibration, bearing damage, or during major overhauls—and highlight compatible machinery models.
