Excavator Engine Crankshaft

If you're dealing with engine vibration, abnormal noise, or power loss on your Doosan DX500LC-9C or DX500-9C excavator, a worn or damaged crankshaft is often the root cause. Our replacement crankshaft, part number 150107-00527, is engineered to directly match the OEM specifications of your Doosan engine, eliminating the risk of fitment issues or compatibility errors during installation.

Unlike generic aftermarket parts, this crankshaft is forged from high-grade alloy steel, then precision-machined and dynamically balanced to meet the strict tolerances required for heavy-duty construction machinery. Each journal surface is ground to the exact diameter needed to maintain proper oil film thickness, preventing premature wear and ensuring stable oil pressure even under full-load operation. We've also retained all OEM oil passages and lubrication points, so you won't need to modify any engine components during installation.

This crankshaft is specifically built for the demanding cycles of excavator use-where engines frequently operate at high loads and varying speeds. It undergoes hardness testing and dimensional inspection before leaving our warehouse, so you can be confident in its performance. The part comes with a 1-year warranty against manufacturing defects, covering issues that may arise under normal operating conditions.
